2.0 SUMMARY OF RESULTS
This section provides summaries of the stack gas parameters and HAP emissions
measured during the test program. Testing of the Waukesha 3521GL engine was conducted
August 4 through August 6,1999 at CSU's Engines and Energy Conversion Laboratory in
Fort Collins, Colorado. The following sub-sections present the test times and durations,
engine and stack gas parameters, and HAP concentrations and mass flow rates before and
after the oxidation catalyst. The end of this section contains a discussion of the efficiencies
at which the catalyst removed HAP.
CSU submitted a report documenting the results of the test program to PES. This
report is reproduced in its entirety in Appendix A. PES discovered errors in the combustion
products (Fa) factors calculated by CSU, which resulted in errors in the calculations of
pollutant mass flow rates. PES requested that CSU correct the errors and re-submit the
emissions calculations so that the final report could be completed. The corrected results
submitted by CSU showed that only 9 of the sixteen runs used the correct Fd values. Slight
errors still exist in CSU's calculated results for Runs 2,4, 7, 8,10,11, and 12. In the tables
mat follow, the correct Fd values are used for each run. PES believes that the values
expressed in these tables are correct representations^of pollutant mass flow rates during the
test program.
2.1 EMISSIONS TEST LOG
During the test period, the test team conducted thirty-four test runs using FTIRS and
GEMS. These test runs consisted of sixteen 5-minute Quality Control (QC) runs, sixteen 33-
minute sampling runs for collection of FTIRS and CEMS data, and two 5-minute baseline
runs. Table 2.1 presents the emissions test log. The test log summarizes the date and time
that each run was conducted. Additional discussions regarding me engine operating
parameters may be found in Section 3.0 of this document.
In Table 2.1, the sampling runs are presented in the order that they were conducted.
In the tables that follow Table 2.1, the sampling runs are presented in numerical order.
During the test program, engine conditions were set by making small changes in engine
operation from run to run rather than large changes. The purpose of this approach was to
reduce both the times between test runs to change an engine condition and the time required
for the engine to stabilize after each change. The effect on the test program was that the
engine load conditions for which emissions data were sought were not conducted in the same

Formaldehyde was detected at the upstream and downstream locations during every m
sampling run. Neither acetaldehyde nor acrolein were detected on any sampling run either
before or after the catalyst. Run by run detection limits for the FTIRS compounds are •
presented in Table 6.1.
EECL personnel operated two GEMS sampling and analysis systems. Engine exhaust g
gas samples were extracted from locations before and after the catalyst, conditioned, and
transported to the GEMS analyzer racks. Moisture was removed from the gas sample before j^
introduction to the O2, CO2, CO, and NOX analyzers. All of the GEMS target compounds |
were detected at the catalyst inlet and catalyst outlet.
The reported concentration of NMHC at the catalyst outlet for Run No. 8 was 284 I
ppmv as methane. The reported concentration at the catalyst inlet was 171 parts per million
by volume (ppmv) as methane. CSU examine the NMHC data and invalidated the data for 9
this run. At the direction of the WAM, the NMHC values obtained during the 5-minute QC •
run conducted just prior to Run No. 8 were substituted at both locations. The NMHC
concentrations were 168 ppmv as methane and 155 ppmv as methane at the catalyst inlet and •
outlet locations, respectively. These values are presented in Appendix C of the CSU test P
report. «
V
2.4 DESTRUCTION OF HAP BY THE CATALYST
There are five possible HAP mass flow rate combinations that can occur across the
oxidation catalyst. Table 2.4 presents these combinations, and notes whether a destruction ^
efficiency is reported. Out of the five possible combinations, there are two instances where |
the destruction efficiency of the target pollutant is reported. If the mass flow rate of a
pollutant into the catalyst (Qin) is greater than the mass flow rate exiting the catalyst (Qout), j*
%DE is calculated. If the pollutant is detected entering the catalyst, but is not detected £
exiting the catalyst, %DE is estimated using the measured mass flow rate at the inlet, and the
mass flow rate corresponding to the analytical detection limit at the outlet. •
The removal efficiency of HAP for various target compounds is presented in
Table 2.5. Formaldehyde was detected on every run that was attempted. In every case, the •
mass flow rate of formaldehyde into the catalyst was greater than the mass flow rate of ~
formaldehyde leaving the catalyst. Therefore sixteen formaldehyde removal efficiencies
were reported. Neither acetaldehyde nor acrolein were detected on any run at either location. m
There are no removal efficiency data to present for either of these compounds.
The removal efficiency of NOX is not presented for any run. In every case, the ,£
measured concentration of NOX at the catalyst exit was greater than the measured
concentration of NOX at the catalyst inlet. The difference between the outlet and the Met •

values ranged from 5 parts per million by volume, dry basis (ppmvd) to 11 ppmvd, which is
1.0 to 2.2% of the measurement range (0 - 500 ppmvd) of the NOX analyzers. The apparent
increase in NOX across the catalyst may be due to uncertainty inherent in using two
analyzers, and not due to any increase in the mass flow rate of NOX. Carbon monoxide was
detected at the catalyst inlet and outlet on every run. The mass flow rate of carbon monoxide
showed a marked decrease across the catalyst. Carbon monoxide destruction efficiencies are
presented for every run.
Methane and NMHC were detected by each methane/NMHC analyzer at both
locations for every run. There are sixteen removal efficiencies calculated. The difference hi
methane concentrations across the catalyst averaged approximately 160 ppm for all of the
runs. This corresponds to about 3% of the methane analytical range of 0 - 5,000 ppmv. The
small difference makes it difficult to determine if there was a reduction hi methane across the
catalyst, or if the differences are due to uncertainty inherent in using two analyzers. The
difference between the NMHC concentrations measured at the catalyst inlet and the catalyst
outlet averaged about 30 ppm for all of the runs. This difference is about 6% of the NMHC
analytical range of 0 - 500 ppmv. The data indicates that some NMHC was probably
removed by the catalyst.
There are no destruction efficiencies presented for total hydocarbons. In fifteen of
sixteen cases, the mass flow rate of THC exiting the catalyst was greater than the mass flow
rate of THC entering the catalyst. The difference in the concentration measurements at these
locations approached 1% of the THC analytical range of 0 - 5,000 ppmv. Therefore, there
was most likely no removal of THC across the catalyst. Since THC is made up mostly of
methane, this seems to indicate that the difference in methane values was most likely due to
inherent measurement errors.

3.0 SOURCE DESCRIPTION AND OPERATION
This section presents discussions of the candidate engine and the catalyst used for the test
program. The sections that follow describe the engine and the operation of the engine during
testing.
3.1 ENGINE DESCRIPTION
The Waukesha 3521GL is a 4-stroke stationary internal combustion engine. The engine
has six inline cylinders; the total piston displacement is 3520 cubic inches. Each cylinder is
9.375 inches in diameter, and has an 8.5-inch stroke. The compression ratio is 10.5:1. Air is
delivered to the engine via the EECL's pressurized air delivery system; air manifold pressures are
controlled by the EECL process control system. Engine loading is controlled by a computer-
controlled water brake dynamometer. Before the test program EECL installed an oxidation
catalyst, manufactured by MiraTech Corporation, on the engine. EECL aged the catalyst under
its normal operating condition (i.e., burned in the catalyst) before the test program. This
procedure ensured that the catalyst's HAP destruction efficiency approximated the HAP
destruction efficiency of mature catalysts installed on 4-stroke engines in industry. Table 3.1
presents specifications of the engine and the catalyst. Table 3.2 presents nominal engine
operating parameters.
The 4-stroke cycle requires two revolutions of the engine crankshaft for each power
stroke. During the intake stroke, the piston moves down the cylinder and an air/fuel mixture is
injected into the piston chamber. On the compression stroke, the piston moves back up the
chamber, and the mixture is compressed and ignited. The expanding gas generated upon
combustion forces the piston back down the chamber. This stroke is the power stroke. The last
stroke of the 4-stroke cycle is the exhaust stroke. The piston travels back up the chamber and the
combustion products are vented through the exhaust manifold.
The 3521GL engine was outfitted with lean-burn technology, which controls NOX
emissions. The lean-burn system uses pre-combustion chambers to ignite a lean air/fuel mixture
in the main combustion chambers. A rich mixture of air and fuel is drawn into the pre-
combustion chamber and is ignited by a spark plug. The resulting flame is then directed into the
main combustion chamber, which contains a lean mixture of air and fuel. The flame jet from Hie
pre-combustion chamber ignites the air/fuel mixture in the main chamber.

3.2 ENGINE OPERATION DURING TESTING
As stated in Section 2 of this document, three types of test runs were conducted during ^
the test program: quality control runs, sampling runs for FTIRS and GEMS, and baseline runs. •
The operation of the engine during these various runs is discussed in the following pages and
tables. The four-stroke engine test matrix described in the QAPP was based upon estimated mm
operating parameters for a candidate engine to be installed and operated at the EECL. When the £
engine was received and first operated by EECL the actual operating parameters differed from
the estimates. Table 3.3 presents the test matrix for the Waukesha engine based upon the actual m
engine parameters. During the test program, the six engine operating parameters expected to |
have the greatest impact on pollutant formation were varied from their baseline values. These
parameters were: engine speed (measured in revolutions per minute or rpm), engine torque •
(measured in foot-pounds or ft-lb), air-to-fuel ratio (calculated as an equivalence factor), engine •
timing (the location of the piston, relative to top dead center, at the tune of spark in the pre-
combustion chamber, measured in degrees), air manifold temperature (measured in degrees •
Fahrenheit), and jacket water outlet temperature (measured in degrees Fahrenheit). »
Table 3.4 presents engine parameters recorded during each test run and their percent •
deviation from the target values. Sixteen sampling runs were conducted on the engine during the !™
two-day period. Except for air/fuel ratios, the actual parameters agreed with the target
parameters to within 5%. Although the calculated air/fuel ratios were not within 5% of the target •
air/fuel ratios, testing was conducted while operating at rich air/fuel ratios (Runs 5 and 8) and at ~
lean air/fuel ratios (Runs 6 and 7). The air/fuel ratio was varied to simulate the range of air/fuel ~
ratios that typcial in field applications. ' £
Before starting Run 7, the humidity control system failed. The humidity system could not ,g
be repaired quickly so the run was conducted without inlet air humidity control. Run 2 was also |
conducted without inlet air humidity control. The set point for the humidity ratio for all test
points was 0.015 Ib. water / Ib. air. The actual humidity ratios for Runs 2 and 7 were 0.0126 and -m
0.0127 Ib. water / Ib. air respectively. The engine emissions for Runs 2 and 7 should be similar fl
to engine emissions at the specified humidity ratio. The most dramatic effect will be on NOX
emissions as can be seen from the data and the graphs presented in Appendix S of the CSU test K
report. At a constant humidity ratio, it would be expected that formaldehyde emissions would •
either remain constant or increase slightly with similar changes hi CO and THC emissions.

Table 3.5 presents engine parameters measured during two baseline test runs. There were
two testing periods. On August 4, testing was conducted over a six-hour period. The engine was
shut down and testing resumed on August 5. The testing was completed over the next 26 hours
of continuous engine operation. Test accuracy required that the overall engine operation did not
change. The stability of the engine over this period was demonstrated by operating the engine at
the baseline condition for one 5-minute period early hi the 26-hour period and a second 5-minute
period at the end of the testing. Changes to the baseline parameters would have Indicated a
change in the overall operating characteristics of the engine. It would not have been possible to
distinguish between emission rate changes attributable to changes hi the Independent variables
and emission rate changes attributable to random changes in the performance of the engine.
Table 3.5 compares the values of 13 engine parameters measured during the baseline runs to the
manufacturer's recommended settings that were presented hi Table 3.2. Deviations are
calculated in percent. Temperatures were converted to degrees Rankine, then the percent
deviation was calculated.

4.0 SAMPLING LOCATIONS
A schematic drawing of the exhaust gas piping on the Waukesha 3521GL engine is
shown in Figure 4.1. The engine exhaust manifold was connected to the inlet of the catalyst with
an 8-inch internal diameter (ID) pipe. The pipe extended vertically from the exhaust manifold,
made a 90° bend, and was connected to the inlet of the catalyst. A 12-inch diameter pipe
connected the outlet of the catalyst to a back pressure valve, and then to the exhaust header.
EECL personnel used two sampling ports to extract samples for analysis by FTIRS and GEMS.
One port was located before the catalyst and one port was located after the catalyst.

5.0 SAMPLING AND ANALYSIS METHODS
This section discusses the various sampling and analysis methods employed by PES and
EECL to quantify the HAP emission rates upstream and downstream of the oxidation catalyst.
PES selected the sampling and analysis procedures that would provide the information required
during the planning stages of the project. The methods were selected to provide the required data
in the most economical fashion, while providing the quality required by EPA's Emissions
Standards Division (BSD).
Table 5.1 summarizes the parameters measured, the sampling methods, and measurement
principle. The text that follows presents brief descriptions of the sampling and analysis
procedures used.
PES and EECL used QA and calibration procedures described in 40 CFR 60, Appendix A
(or other references as appropriate) as a guideline for instrument calibrations and drift checks.
The instrumental methods as written in 40 CFR 60 Appendix A are designed by EPA to be
portable, field test procedures. Because these instruments are maintained in a laboratory-type
environment (the control room at EECL), fewer QA activities and calibrations are required to
adequately show their continuing accuracy. The only significant change to the quality assurance
activities was that fewer instrument calibrations were done to quantify instrument drift.
Historical calibration data for the instruments shows their stable operation over extended, e.g.,
24-hour, periods. Multipoint calibrations'were conducted (including the sampling system bias
checks) on these instruments once at the beginning of each engine test series.
5.1 DETERMINATION OF STACK GAS VOLUMETRIC FLOW RATE
PES used EPA Method 19 to calculate the volumetric flow rate of the exhaust gases for
Runs 1 through 16. The mass flow rates of pollutants measured by FTIRS and GEMS were
calculated using the Method 19 flow data. EPA Method 19, Determination of Sulfur Dioxide
Removal Efficiency and Paniculate Matter, Sulfur Dioxide, and Nitrogen Oxides Emissions
Rates, uses a fuel factor to calculate the volume of combustion products generated upon
combustion of specific fuel types. EECL personnel analyzed a sample of the natural gas fuel
during each day of testing. The results of the compositional analysis were used to calculate the
upper heating value and oxygen-based F-factor, Fd. The EECL Engine Control and Monitoring
System recorded stack gas O2 concentrations and the fuel consumption rate during testing. These
data were used to calculate the exhaust gas flow rates by multiplying the fuel consumption by the
fuel factor, and correcting for excess air. Exhaust gas flow rates were calculated upstream and
downstream of the catalyst for each run.

5.2 DETERMINATION OF STACK GAS OXYGEN AND CARBON DIOXIDE
CONTENT
EECL used EPA Method 3 A, Determination of Oxygen and Carbon Dioxide
Concentrations in Emissions from Stationary Sources (Instrumental Analyzer Procedure), to
measure oxygen and carbon dioxide content of the exhaust gas during testing. EECL's sample
gas extraction and transport system extracted a gas sample from locations upstream and
downstream of the catalyst. Each sample was conditioned to remove moisture and entrained
particulate matter and directed to the CEMS.. Oxygen was measured using the paramagnetic
detection principle. Carbon dioxide was measured using non-dispersive infrared (NDIR)
analyzers. The oxygen and carbon dioxide monitors were calibrated with a pre-purified zero gas
and three upscale gas standards corresponding to approximately 30, 55 and 85 percent of the
instruments' analytical ranges. EECL used only EPA Protocol gas standards certified by the gas
manufacturer. The calibration gases that were used and the calibration responses of the
instruments are discussed in Section 6.0 of this document. A schematic diagram of the
FTIRS/CEMS sampling and analysis system is presented in Figure 5.1.
5.3 DETERMINATION OF STACK GAS MOISTURE CONTENT
EECL used two methods to determine the moisture concentration hi the exhaust gas
upstream and downstream of the catalyst. Moisture content downstream of the catalyst was
calculated using a carbon balance method. This method is summarized in the EECL test report,
which may be found hi Appendix A. During the testing, EECL personnel determined that the
moisture concentrations downstream of the catalyst, as measured by the Nicolet Magna 560
FTIR analyzer, were about 6 percent higher than actual. Therefore the carbon balance method
was used to calculate moisture content at this location.
EECL used methodology described in the document Measurement of Select Hazardous
Air Pollutants, Criteria Pollutants, and Moisture Using Fourier Transform Infrared (FTIR)
Spectroscopy to measure moisture concentrations upstream of the catalyst This document,
called the GRI Protocol in this report, is presented as Appendix B of a report published by the
Gas Research institute: Fourier Transform Infrared (FTIR) Method Validation at a Natural Gas-
Fired Internal Combustion Engine. A sample of the gas was extracted from the exhaust, filtered
and directed to a Nicolet Rega 7000 FTIR analyzer to measure the moisture concentration. The
gas sample was transported to the analyzer via a heated Teflon® sample line. Further discussion
of the FTIRS sampling and analysis method may be found hi the report generated by the EECL.
5.4 DETERMINATION OF NITROGEN OXIDES
EPA Method 7E, Determination of Nitrogen Oxide Emissions from Stationary Sources
(Instrumental Analyzer Procedure), determined nitrogen oxide content of the exhaust gases.

These tests also provided the data needed to do the EPA Method 301 validation of the FTIRS for
NOX emissions from this source. Gas samples were extracted from locations upstream and
downstream of the catalyst, conditioned to remove moisture, and the nitrogen oxide
concentration determined by chemiluminescence analyzers. The NOX monitors were calibrated
with a pre-purified zero gas, and two upscale gas standards corresponding to approximately 55
and 85 percent of the instruments analytical ranges. EECL used EPA Protocol gas standards
certified by the gas manufacturer. The calibration gases that were used and the calibration
responses of the instruments are discussed in Section 6.0 of this document. A schematic diagram
of the FTIRS/CEMS sampling and analysis system is presented hi Figure 5.1.
5.5 DETERMINATION OF CARBON MONOXIDE
EPA Method 10, "Determination of Carbon Monoxide Emissions from Stationary
Sources," measured CO concentration of the exhaust gas during the testing. These tests also
provided the data needed to do the EPA Method 301 validation of the FTIRS sampling and
analysis system for CO emissions from this source. Gas samples were extracted from the
exhaust gas streams, conditioned to remove moisture, and the carbon monoxide concentration
determined by instrumental analyzers. The measurement principle for carbon monoxide is
GFC/NDIR. The CO monitor was calibrated using a pre-purified zero gas and three upscale gas
standards corresponding to approximately 30, 55 and 85 percent of the instrument's analytical
range. All gas standards used for calibrations were prepared according to EPA Protocol and
certified by the gas manufacturer. The calibration gases that were used and the calibration
responses of the instruments are discussed in Section 6.0 of this document. A schematic diagram
of the FTIRS/CEMS sampling and analysis system is presented hi Figure 5.1.
5.6 DETERMINATION OF TOTAL HYDROCARBONS
EPA Method 25A, Determination of Total Gaseous Organic Concentration Using a
Flame lonization Analyzer, determined the total hydrocarbon concentrations at the inlet and the
outlet of the catalyst. At the catalyst inlet, EECL used a Thermo Environmental Instruments
(TECO) Model 51 Total Hydrocarbon Analyzer. The analyzer consisted of a heated
compartment to prevent condensation of organic compounds, and a Flame lonization Detector
(FID) to measure THC concentrations. At the catalyst outlet, EECL used a Rosemount
Analytical NGA-2000 FID Hydrocarbon Analyzer. This analyzer also used an FID to measure
the concentrations of THC in the gas stream. The FID detector consists of a burner hi which a
regulated flow of a sample gas passes through a flame sustained by regulated flows of a fuel gas
and air. The hydrocarbon components of the sample stream ionize in the flame. The positive
ions that are produced are collected by an electrode causing current to flow through a measuring
circuit. The ionization current is proportional to the rate at which carbon atoms enter the burner,
and is therefore a measure of the concentration of hydrocarbons in' the sample.

I
5.7 DETERMINATION OF METHANE AND NON-METHANE HYDROCARBONS 1
A modification of EPA Method 25 A determined the methane and non-methane •
concentrations at the inlet and the outlet of the catalyst. Gas samples extracted from each gas »
stream were transported to Questar Baseline 1030H Methane/Non-Methane Analyzers. These
analyzers are single-purpose gas chromatographs that separate methane from the other organic I
compounds hi the sample by passing the sample through a separation column. The methane "
elutes from the column first and is directed to the flame ionization detector. Then, the analyzer
reverses the flow through the column and the remaining organic compounds are back flushed to •
the same detector. The analyzer sums the two fractions to yield the concentration of total organic
compounds. Because this unit is a gas chromatograph, it cannot measure methane and non- •
methane concentrations continuously. During testing, each analyzer determined concentrations •
once every five minutes. This frequency is sufficient for testing on RICE, because the operating
conditions were maintained within close constraints. Each analyzer was calibrated before each •
week of testing using methane and propane calibration standards corresponding to approximately m
30, 50, and 85 percent of the instrument span. The calibration gases that were used and the
calibration responses of the instruments are discussed in Section 6.0 of this document. A •
schematic diagram of the CEMS/FTIRS sampling and analysis system is presented in Figure 5.1. •
5.8 DETERMINATION OF GASEOUS ORGANIC HAPS USING FTIRS •
EECL used two FTIRS systems that met the sampling and analysis requirements set forth •
in the GRI Protocol. Table 5.2 summarizes the specifications of each FTIRS analyzer. GRI
validated extractive FTIRS systems successfully for an analysis of emissions from natural gas- m
fired RICE. The extractive FTIRS Continuously extracts a sample gas from the stack, transports •
the sample to the FTIRS system, and does spectral analysis of the sample gas. The computer
system analyzes sample gas spectra for target analytes continuously and archives them for •
possible later re-analysis. I
The sampling and measurement system consists of the following components: I
• heated probe; •
• heated filter; I
• heat-traced Teflon® sample line;
• Teflon® coated, heated-head sample pump; I
• FTIRS spectrometer; and •
• QA/QC-apparatus.

EECL validated each sample extraction and analysis system for formaldehyde,
acetaldehyde, and acrolein before testing. The results of the FTIRS validation are discussed in
Section 6. The basic sampling procedure consisted of EECL taking an initial interferogram of
the stack gas with the FTIRS measurement and analysis system before each test to describe the
sample matrix. This measured the concentrations of moisture and the target pollutants and
allowed for adjustments to the cell pathlength and the spectral analysis regions if the
concentrations differ from expectations. Sample conditioning was not necessary at the EECL
test site.
After QA/QC procedures and initial adjustments were completed for a given test day, a
gas sample was drawn continuously through the heated FTIRS cell while the system collected
spectral data. The spectrometer collected one complete spectrum of the sample, as an
interferogram, per second and averaged interferograms over 1-minute periods. The FTIRS
computer converted these tune-integrated interferogram into conventional wave number spectra,
analyzed for the target compounds and archived the data. Sample collection was '33 minutes in
duration, coinciding with the test runs.
5.9 DETERMINATION OF NATURAL GAS COMPOSITION
The composition of the fuel gas combusted in the engine was determined daily using a
dedicated Daniels Industries gas chromatograph (GC). The GC was calibrated each day using a

BTU content of the fuel were calculated. Fuel flow measurements were determined using an
American Gas Association (AGA) specified orifice meter run equipped with high accuracy •
pressure and temperature transmitters. All fuel flow calculations were in accordance with AGA •
Report #3. Stoichiometric air to fuel ratio calculations were also made using the results of the
fuel gas analysis. The results of fuel gas calibrations and analysis are presented in the EECL I
report, which is attached in Appendix A. ™

6.0 QUALITY ASSURANCE/QUALITY CONTROL
PROCEDURES AND RESULTS
Summarized in this section are the specific QA/QC procedures that PES and EECL
personnel employed during the performance of this source testing program. PES' quality
assurance program was based upon the procedures and guidelines contained in the "Quality
Assurance Handbook for Air Pollution Measurement Systems, Volume III, Stationary Source
Specific Methods," EPA/600/R-94/038c, as well as in the test methods. These procedures
ensure the collection, analysis, and reporting of reliable source test data.
6.1 FTIRS QA/QC PROCEDURES
EECL calibrated the FTIRS instruments before each engine test series and at the
beginning and end of each test day. The calibration procedures employed were consistent
with procedures found in the following documents:
Gas Research Institute Report Number GRI-95/0271 entitled, "Fourier Transform
Infrared (FTIRS) Method Validation at a Natural Gas-Fired Internal Combustion
Engine."
This report was prepared for the Gas Research Institute by Radian Corporation.

EPA Method 301 validation process for formaldehyde, acetaldehyde, and acrolein. The I
validation process quantified the precision and accuracy of each FTIRS analyzer for these
compounds. Besides the validation program, EECL personnel performed the following •
calibration procedures before each engine test series. •
1. Source Evaluation - Initial source data were acquired to verify concentration •
ranges of target compounds and possible interferences. This was completed ™
before and during the Method 301 validation process for formaldehyde,
acetaldehyde, and acrolein, and during the test program for moisture. •
2. Sample System Leak Check-A leak check was done on the portions of the •
system between the sample filter and the pump outlet. A rotameter was connected |
to the discharge side of the sample pump. The indicated sample flow rate was
recorded with the sample system operating at typical temperatures and pressures •
(the sample pump pulled a slight vacuum on the suction side). The inlet was |
closed off just downstream of the sample probe. The rotameter monitored the
flow rate. If the leakage rate is found to be no greater than 500 ml/min or 4% of •
the average sampling rate (whichever is less) the system is considered to be •
acceptable for use. The leak checks conducted by EECL personnel indicated that
the system was acceptable for use. •
3. Analyzer Leak Check - Both FTIRS analyzers were checked to ensure that they
were operating at normal operating temperatures and pressures. The operating •
pressures were recorded. The automatic pressure control device was disabled and
the inlet to the FTIRS was closed. The cell was evacuated to 20% or less of the . g
normal operating pressure. After the cell was evacuated, it was isolated and the I
cell pressure was monitored with a dedicated pressure sensor. The leakage rate of

4. Cell Pathlength Determination - The FTIRS cell pathlengths were to be •
determined using the procedure outlined in the Field Procedure Section the •
document entitled "Protocol for Performing Extractive FTIRS Measurements to
Characterize Various Gas Industry Sources for Air Toxics." Because each FTIRS •
was a fixed pathlength unit (i.e., the pathlengths were not adjustable) •
measurements of the cell pathlengths were deemed unnecessary. The cell
pathlengths specified by the manufacturer were used in the measurement •
algorithms.

6.1.2 FTIRS Daily Calibrations and OA Procedures
Before each day of testing, EECL personnel calibrated each FTIRS system following
the procedures outlined below.
1. Instrument Stabilization - Each of the following components were checked for
proper operation to ensure the stability of the operation of the FTIRS instruments:
a) Instrument heaters and temperature controllers.
b) Pressure sensors and pressure controllers.
c) Sample system (pump, filters, flow meters, and water knockouts).
2. The FTIRS analyzers were purged with conditioned air for a minimum of
30 minutes before conducting background spectrum analysis. During periods
when the instruments were in stand-by mode (i.e., between sampling runs or
between test days), they were maintained at normal operating temperatures and
purged with conditioned air.
3. Background Spectrum Procedures — Each instrument was allowed to stabilize
while being purged with Ultrahigh Purity (UHP) nitrogen for 10 minutes. The
FTIRS spectra were monitored during this time, until CO and H2O concentrations
reached a steady state. The following procedures were then done:
a) The interferogram signal was checked using signal alignment software.
b) A single beam spectrum was collected and inspected for irregularities.
c) Using the single beam spectrum, the detector was checked for non-linearity
and corrected if necessary.
d) The instrument alignment procedure was done.
e) A background spectrum consisting of 256 scans was collected.
4. Analyzer Diagnostics - Analyzer diagnostics were done by analyzing a diagnostic
standard. The standard was a 109 ppm CO EPA Protocol gas standard. EECL
uses CO because it has distinct spectral features that are sensitive to variations in
system operation and performance. The standard was introduced directly into
each instrument, and instrument readings were allowed to stabilize for 5 minutes.
The accuracy and precision of each instrument were calculated. The pass/fail
criterion for accuracy and precision was 10% of the concentration of the standard

I
gas. A second diagnostic standard consisting of a blend of CO2, CO, CH4> and |
NOX was analyzed using the same procedure. Each instrument met the precision
and accuracy requirements. Analyzer diagnostic data are presented hi the report •
generated by EECL. •
5. Indicator Check & Sample Integrity Check - An indicator check was done by jl
analyzing an indicator standard. A 10.66 ppm formaldehyde standard was •
introduced directly into each instrument. The instrument readings were allowed
to stabilize and a 5-minute data set was collected. The indicator standard was •
then introduced into the sample system at the sample probe, just upstream of the
filter. The instrument readings were allowed to stabilize and a 5-minute set of _
data was collected. The accuracy, precision, and recovery were calculated based |
on equations in the document entitled "Protocol for Performing Extractive FTIRS
Measurements to Characterize Various Gas Industry Sources for Air Toxics", •
prepared by Radian Corporation for the Gas Research Institute. The pass/fail |
criterion for accuracy, precision, and recovery is 100 ± 10% of the known
standard (recovery shall be 100 ± 10% of the instrument reading when the •
indicator gas is introduced directly into the instrument.) Each instrument met •
these criteria. Indicator check and sample integrity data sheets are included with
the EECL report. •
6.1.3 Background Assessment
During data acquisition procedures, the baseline absorbance was continually
monitored. If at any time the baseline spectrum changed by more than 0.1 absorbance units,
the instrument's interferometer was realigned and a new background spectrum collected. •
6;1.4 Post Test Checks •
Upon completion of the daily test program steps 4 and 5 of the pre-test calibration
procedures were repeated. Both of the FTIRS analyzers met all of the acceptance criteria for m
the calibration and QA procedures. Post test calibration data sheets are included in the EECL |
report.
6.1.5 FTIRS Validation •
Before the test program, both FTIRS sampling and analysis systems were validated •
for formaldehyde, acroleiri, and acetaldehyde. The validation was conducted by personnel *
from ERG, using procedures outlined in EPA Method 301 "Field Validation of Pollutant
Measurement Methods from Various Waste Media." The validation was conducted by •
spiking the sample gas with known concentrations of formaldehyde, acrolein, and
acetaldehyde. The carrier gas was a mixture of acrolein and acetaldehyde and was introduced _
into the spiking system from a compressed gas cylinder. Formaldehyde was added to the |

-------
carrier gas by injecting a stock formalin solution onto a heated block at a fixed rate. The
acrolein/acetaldehyde gas standard was used as a carrier gas for the vaporized formaldehyde.
The three-component mixture was injected into each FTIRS sampling system at a point
upstream of each system's filter. Further discussions of the validation procedures employed
may be found in the report generated by EECL.
6.1.6 FTIRS Detection Limits
Table 6.1 presents the in-stack detection limits for formaldehyde, acetaldehyde, and
acrolein as reported by CSU EECL. These detection limits have been used to calculate the
run-by-run mass detection limits for each of the target pollutants.
6.2 CEMS QA/QC PROCEDURES
The following paragraphs describe the CEMS quality assurance procedures that
EECL personnel used during the test program. The calibration and QC frequencies far
exceeded those required for permanently-installed, compliance analyzers, but are less than
those specified for compliance tests by EPA (40 CFR 60, Appendix A). EECL operates their
CEMS in a way that is more similar to permanently-installed analyzers.
6.2.1 Analyzer Calibration Gases
EECL used EPA Protocol calibration gases. The calibration gases were manufactured
by Scott Specialty Gases. For this program, EPA Protocol 1 calibration gases (RATA Class)
were used. Formaldehyde and acetaldehyde/acrolein standards with concentration ranges
between 5-20 ppm were obtained for FTIRS calibrations. These gases are not available as
EPA Protocol Gases, so EECL specified the highest quality available. Scott supplied
certification sheets, which may be found in the Appendices of EECL's test report.
6.2.2 Response Time Tests
Response tune tests were done on each sample system before initiation of the engine
test program. The response time tests were performed before the FTIRS validation process
for each sampling system. The response tune of the slowest responding analyzer (Questar
Baseline Methane/Non-methane hydrocarbon GC) was determined. Response tune tests
conducted at the EECL indicated sampling system response tunes of 1:10 minutes. This is
the tune for the Rosemount Oxygen analyzer (the slowest responding continuous analyzer) to
stabilize to response output of the analyzer. The Questar Baseline analyzers have a minimum
cycle time of 4:50 minutes. The overall response time for these analyzers when their cycle is
started 1:10 minutes after a sample source change is 5:50 minutes.

6.2.3 Analyzer Calibrations
Zero and mid-level span calibration procedures were done on the CO, CO2, O2, NOX,
THC, and methane/non-methane analyzers before each test day. Zero and span drift checks
were performed upon completion of each data point and upon completion of each test day. A
zero and mid-level gas was introduced directly to the analyzers before testing for carbon
monoxide, carbon dioxide, oxygen, total hydrocarbons, methane/non-methane, and oxides of
nitrogen. The analyzers' output response was set to the appropriate levels. Each analyzer's
stable response was recorded. From this data a linear fit was developed for each analyzer.
i The voltages for each analyzer were recorded and used hi the following formula:
Y = MX + B
where: B = Intercept
M = Slope
X = Analyzer or transducer voltage
Y — Engineering Units
After each test point and upon completion of a test day, calibrations were conducted
by reintroducing the zero and span gases directly to the back of the analyzers. The analyzers'
stabilized responses were recorded. No adjustments were made during testing or during the
final calibration check. Initial calibration values and all calibration checks were recorded for
each analyzer during the daily test program.
The before and after calibrations checks were used to determine zero and span drift
for each test point for the CO, CO2, O2, NOX, THC, and methane/non-methane, and analyzers.
The zero and span drift checks for all test points and all test days were less than ±2.0% of the
span value of each analyzer used during the daily test program. The calibration data sheets
are presented in the test report generated by EECL. Table 6.2 presents the types and
frequencies of the analyzer calibrations conducted by EECL.

6.2.4 Analyzer Linearity Check
Analyzer linearity checks were done before beginning the test program. The oxygen,
carbon monoxide, total hydrocarbon, methane/non-methane, and oxides of nitrogen analyzers
were "zeroed" using either zero grade nitrogen or hydrocarbon free air. The analyzers were
allowed to stabilize and their output recorded. The analyzers were then "spanned" using the
mid-level calibration gases. The analyzers were allowed to .stabilize and their output
recorded. From this data a linear fit was developed for each analyzer. The voltage for each
analyzer was recorded and used in the following formula:
Y = MX + B
where: B = Intercept
M = Slope
X = Analyzer or transducer voltage
Y = Engineering Units
Using the linear fit, the linear response of the analyzer was calculated. Low-level and
high-level calibration gases were individually introduced to the analyzers. For each
calibration gas, the analyzers were allowed to stabilize and their outputs were recorded. Each
analyzer's linearity was acceptable. The predicted values of a linear curve determined from
the zero and mid-level calibration gas responses agreed with the actual responses of the low-
level and high-level calibration gases within ±2.0% of the analyzer span value. The
methane/non-methane analyzers' linearity was acceptable as the predicted valued agreed with
the actual response of the low-level and high-level calibration gases within ±5.0% of the
actual calibration gas value. This procedure was done for one range setting for each analyzer.
The Linearity Check data sheets are presented the test report generated by EECL.
6.2.5 NO7 Converter Check
EECL did NO2 converter checks before the test program began. A calibration gas
mixture of known concentration between 240 and 270 ppm nitrogen dioxide (NO2) and 160
to 190 ppm nitric oxide (NO) with a balance of nitrogen was used. The calibration gas
mixture was introduced to the oxides of nitrogen (N

exhaust stack probe. With the sample pump operating, a vacuum was pulled on the exhaust |
sample train. Once the maximum vacuum was reached, the valve on the pressure side of the
pump was closed, thus sealing off the vacuum section of the sampling system. The pump •
was turned off and the pressure in the sample system was monitored. The leak test was •
acceptable as the vacuum gauge reading dropped by an amount less than 1 inch of mercury
over a period of 1 minute. The Sample Line Leak Check data sheets are presented the test I
report generated by EECL.
6.2.7 Sample Line Integrity Check £
A sample line integrity check was done before and upon completion of each test day. «
The analyzers' response was tested by first introducing a mid-level calibration gas directly to g
the NOX analyzer. The analyzer was allowed to stabilize and the response recorded. The
same mid-level calibration gas was then introduced to the analyzer through the sampling •
system. The calibration gas was introduced into the sample line at the stack, upstream of the |
inlet sample filter. The analyzer was allowed to stabilize and the response recorded. The
analyzer response values were compared and the percent difference did not to exceed ±5% of •
the analyzer span value. •
The sample Ime integrity check was to be done for both the NOX and methane/non- •
methane analyzers. Due to tune constraints, EECL performed the integrity check for the NOX •
analyzers only. The SSB procedure was performed for the methane/non-methane analyzers
before and upon completion of the test program. The Sample Line Integrity Check data •
sheets are presented in the test report generated by EECL.
6.2.8 Carbon Balance Check |
One of the methods used to calculate mass emissions was a carbon balance •
calculation developed by Southwest Research Institute specifically for the American Gas |
Association. The calculations consist of a theoretical O2 calculation .based upon measured
exhaust stack constituents and fuel gas composition. The theoretical exhaust O2 is then •
compared to the measured exhaust O2. The percent difference between the actual and •
theoretical O2 measurements was within ±5 % of the measured O2 reading. The O2 balance
was performed for every 1-minute average and the 33-minute averaged valued for each test •
point.
6.2.9 Fuel Factor Quality Assurance Checks I
Besides the GEMS calibration and QC checks, carbon dioxide and oxygen
measurements were validated by calculating the fuel factor, Fp, using the following equation:

4, 5, and 6 respectively. The F0 values were within 6% of the calculated F0 for all of the
sampling runs conducted. Based upon the results, the integrity of the CEMS sample stream

6.3 DATA QUALITY ASSESSMENT
EPA used the Data Quality Objective (DQO) Process to plan the test program. The
DQO Process consists of seven distinct steps.
1. State the problem.
2. Identify the decision.
3. Define inputs to the decision.
4. Define the study boundaries.
5. Develop the decision rule.
6. Specify tolerable limits, on decision errors.
7. Optimize the design for obtaining data.

The DQO outputs for this test program were presented in the Quality Assurance
Project Plan. The problem was defined in the QAPP and is restated below.
/
EPA believes that there is a need to conduct emission tests on a subset of engines of
differing designs to evaluate the following issues:
• the effectiveness of after-combustion control systems on HAP emissions, and
• the effectiveness of combustion modifications (engine operating parameters) on
HAP emissions.
EPA then developed a decision statement. The decision statement defined the process
that would be used to answersfhe stated problem. The decision statement is restated below:
If EPA can identify a range of engine operating conditions for a defined set of
engines with specified after-combustion treatment systems and a list of pollutants of
interest, and EPA collects data to determine emissions of those pollutants for each
engine operated at each engine operating condition, then EPA can make a
determination of the control effectiveness of after-combustion and combustion
modifications. In addition, EPA can obtain information on HAP emissions
throughout the engine operating range.
PES and EECL conducted the test program on the Waukesha 3521GL, natural gas-
fired, 4-stroke, lean-burn, reciprocating internal combustion engine. The MiraTech oxidation
catalyst was designed to provide the information required by the decision statement. Based
upon the inputs, EPA will make decisions that will be used to regulate this engine
subcategory. Inputs to the decision were defined, agreed to, and documented in the QAPP.
These inputs consisted of agreement on a finite list of engines to test, the after-combustion
control systems to test, the range of engine operating conditions, the catalyst conditioning
process, the target list of pollutants, and the sampling and analysis methods, and sample
durations.
During conduct of the test program, there were deviations from the QAPP. These
deviations are discussed in Section 3.0 for deviations in engine operation, and Section 5.0 for
deviations in Sampling and Analysis procedures.
Table 6.5 presents a summary of engine and sample method performance compared to
the QAPP requirements. Outlier and data validation issues have been discussed in previous
sections. Based upon the engine and method performance, the data quality is evaluated on a
run-by-run basis for suitability in the assessment of pollutant emissions and destruction
efficiency of HAP by the catalyst.
Six engine parameters were varied over the course of the test program. The
parameters were changed so that emissions data and HAP destruction efficiency could be

evaluated at a range of engine operating conditions. These conditions are expected to |
simulate the range of engine operating conditions in industry. Table 6.5 identifies the
number of engine parameters that were within the tolerances prescribed in the QAPP. The - •
target engine operating conditions were estimates based upon manufacturer's I
recommendations. There are differences between these recommendations and the nominal
engine operating parameters of the Waukesha 3521GL engine located at the EECL. When •
testing was conducted some of the prescribed engine parameters could not be met. The fact •
that a pre-set engine parameter could not be met is considered to be minor. The testing was
conducted over a range of engine operating conditions, and these operating conditions are B
documented. *
The remainder of the table assesses data quality using a three-tiered system. A (/ +) •
indicates that all method performance parameters defined hi the QAPP and/or the sampling
method were met. A (/) indicates that at least 90% of the method performance parameters _
were met. In the case of FTIRS and GEMS detection limits, there were no detection limits . jj
specified in the QAPP. The calculated detection limits are reasonable for this test program.
A (/ -) would indicate that fewer than 90% of the method performance parameters were met. •
There were no cases where less than 90% of the method performance parameters were met. |

1.0 INTRODUCTION
1.1 OVERVIEW
Natural gas fueled and diesel fueled reciprocating engines represent a large portion of the
horsepower in operation within the oil and gas industry and power generation markets. With
stringent emissions regulations being required by federal, state, and local agencies, accurate data on
current engine emission levels and development of new technologies to reduce and control emissions
levels has become essential for federal agencies, engine manufacturers, and equipment operators.
Criteria pollutants and Hazardous Air Pollutants (HAPS) issues are of major concern for operators of
both two-stroke and four-stroke engines. Current Environmental Protection Agency (EPA) and
natural gas industry funded test programs are directed toward evaluating emission levels from
existing engines, determining formation mechanisms for the exhaust gas constituents of interest, and
developing new technologies to reduce the emissions levels of these constituents.
The investigation of the application of commercially available techniques designed to address the
HAPs emissions from reciprocating internal combustion engines (RJCEs) will allow the EPA to
quantify the effectiveness of current commercially available control devices. These devices have
been identified as having the potential to reduce HAPs emissions from stationary RICE sources.
Information gained through this program will assist the EPA in the regulatory development effort.
Accurate information on emission levels from operational facilities is difficult to obtain. Based upon
a recommendation from the Internal Combustion Coordinating Rulemaking Committee (ICCR) to the
EPA, a series of tests were conducted on industrial class -engines at Colorado State University's
Engines & Energy Conversion Laboratory. Testing was being conducted on both two-stroke and
four-stroke natural gas engines and a four-stroke diesel engine. The test program for four-stroke,
lean burn, natural gas fueled internal combustion engine was performed during Phase Two of this test
program. The results of Phase Two testing are contained within this document.
1.2 BACKGROUND
The 1990 Amendments to the Clean Air Act include provisions that significantly impact the
operation of stationary reciprocating internal combustion engines. Of the ten titles to these
amendments, four have direct bearing. They are as follows:
Title I - Attainment of Air Quality Standards
Defines ambient air quality standards, defines non-attainment areas based, imposes
emissions reductions to achieve attainment per specified timeline per reasonably
available control technology (RACT).
Emissions Testing 1-1 Pacific Environmental Services

-------
COLORADO STATE UNIVERSITY m
Title m - Hazardous Air Pollutants |
Defines 189 pollutants classified as hazardous air pollutants (HAPS), specifies
thresholds in tons per year (TPY) for any one of these pollutants or a combination of •
these compounds, introduces maximum achievable control technology (MACT) for B
sources triggering thresholds. ^
TitleV -OperatingPermits
Imposes requirement to obtain federal operating permits for major sources, imposes •
requirement to provide annual certification of compliance, defines emissions fees based |
on actual emissions. ^
•
Title VE -Enforcement
Establish mechanisms to enhance and strengthen enforcement of CAA, establishes M
criminal penalties, gives authority to issue administrative orders (fines / penalties) £
without going to federal court for certain violations.
I
The EPA in conjunction with the RICE Work Group of the ICCR process determined that additional *P
emissions data for HAPs exhaust gas constituents is required to support the regulatory development £
process. In a RICE Emissions Test Plan Document dated November 1997, a five component test plan A
to acquire additional HAPs emissions test data was set forth. The five components include the
following: V
Engines, Fuels, and Emissions Controls to be tested -A
Matrix of Operating Conditions to be tested I
Pollutants to be Measured During Testing
Test Methods to Quantify Emissions
Prioritization
I
Eight HAPs pollutants are included in the test plan. These compounds are: formaldehyde, •
acetaldehyde, acrolein, the BTEX compounds (benzene, toluene, ethylbenzene, xylene) and 1-3 *"
I
butadiene. Polyaromatic hydrocarbon (PAH) compounds were measured on the two-stroke lean burn
gas engine, but were not measured during the test program for the four-stroke lean bum gas engine.
Insight gained through the test program will provide information on the engine operating conditions W
that affect the formation / reduction mechanisms of HAPs. The investigation of the application of •
commercially available techniques designed to address the HAPs emissions from RICEs will allow ^
the EPA to quantify the effectiveness of current commercially available control devices. These •
devices have been identified as having the potential to reduce HAPs emissions from stationary RICE
sources. Information gained through this program will assist the EPA in the regulatory development •
effort. •

2.0 TEST PROGRAM
2.1 OBJECTIVE
The objective of this program is to evaluate commercially available catalyst technologies which have
been identified as having the potential to control both formaldehyde and other Hazardous Air
Pollutants (HAPS) as well as existing criteria pollutants from reciprocating internal combustion
engines (RICE). The specific internal combustion engine class tested under the Phase Two test
program was the four-stroke, lean bum, natural gas fueled internal combustion engines. The catalyst
hardware was evaluated according to the 16-point test matrix developed by the EPA, and the
Reciprocating Internal Combustion Engine (RICE) Work Group of the ICCR process. Investigation
of catalyst performance during operation at various engine operating conditions provides insight into
the effectiveness'of catalysts at various conditions. The information gained through the test program
will assist the EPA in regulatory development efforts for control of HAPs emissions and criteria
pollutants from RICE sources.
2.2 INCENTIVES
Title IH of the 1990 Clean Air Act Amendment requires the development of Maximum Achievable
Control Technology (MACT) standards for major sources of Hazardous Air Pollutants (HAPs)
emissions. A MACT major source is defined as one that emits greater than 10 tons per year of any
single HAP or 25 tons per year for all HAPs. For most source categories (RICE included), the
MACT standards will require existing major sources apply HAPs emissions control technologies that
reduce emissions to a level achieved by the best performing existing sources. In some cases,
depending upon the cost of the control technology and the amount and toxicity of the HAPs removed,
more stringent standards may be set. The MACT standards for RICEs are scheduled to be
promulgated by the year 2000.
Of the HAPs listed, the EPA in conjunction with the Internal Combustion Coordinating Rulemaking
Committee (ICCR) have identified compounds which may be present in the exhaust of reciprocating
internal combustion engines. Existing test data indicates that the only HAP present in the exhaust of
RICEs at levels approaching 10 tons per year is formaldehyde. Commercially available after-
treatment technologies (catalysts) for the control of organic compound emissions are currently in
operation on RICEs. These technologies have demonstrated performance for control of volatile
organic compounds (VOCs) and products of incomplete combustion. However, there is limited
information on the effectiveness of these technologies for reducing organic HAPs emissions.
Determining the effectiveness and longevity of exhaust catalyst will aid the EPA in evaluating
current technologies for control of HAPs emissions from RICE sources as well as provide
information in support of regulatory development by the EPA for these sources.

3.2 FTIR POST-CATALYST WATER ANALYSIS
Analysis method on the Nicolet Magna 560 FTIR analyzer gave water measurements that were
excessively high for post-catalyst emissions measurements. The spectra for H20, provided by
Nicolet, on the Magna 560 calculated water content to be approximately 6% higher than actual
exhaust gas concentrations. Carbon balance calculations for each one-minute data point, at all test
conditions, agreed with the H20 readings from the Rega 7000 FTIR analyzer, pre-catalyst emissions
measurement. The measurements agreed within ±0,5% to ±1% water content The carbon balance
calculations for the post-catalyst water content agreed with the pre-catalyst measurements within
±0.5% to ±1% water content at all test conditions. The carbon balance measurements are based upon
the pre-catalyst and post-catalyst reference method analyzers. Since the pre-catalyst and post-catalyst
measurements were made with separate analyzers, the variability in the H20 calculation could be
caused by variability in emissions analyzers.
The changes in the water content were calculated by the carbon balance method and detected by the
FTIR analyzer. Based on the agreement between the pre-catalyst FTIR measurements and the carbon
balance calculation for water content at every test condition, and between the pre-catalyst and post-
catalyst calculations, the water content from the post-catalyst FTIR measurements were used to
convert the wet FTIR measurements to dry measurements. As both FTIR analyzers passed the
validation process and passed all QC checks, the variation in water readings from the Nicolet Magna
560 analyzer has no impact on the results of the testing conducted during Phase Two of the overall
test program.

Humidity Ratio:
Baseline humidity ratio is 0.015-lb. H20/lb. air. The baseline humidity ratio was stated as
0.0015-lb. H20/lb. air . This is a misprint. Documentation should be corrected to show
0.015-lb. H20/lb. air as baseline humidity ratio.
August 6,1999 Baseline:
The air/fuel ratio appears to be wrong because it is calculated from the output of the pre-
catalyst 02 monitor. The monitor failed during this baseline. The air/fuel ratio is 28:1 when
the 02 is 9.8%. The catalyst outlet 02 is 9.9%, so the air/fuel ratio is correct.

3.4 FOUR-STROKE ENGINE TEST MATRIX
The four-stroke engine sixteen point test matrix and associated engine operating conditions as
described in the Scope of Work are presented in Table 2 of this.report. During testing discrepancies
between the CSU "Scope of Work" and the QAPP in relation to engine operating conditions were
identified. The QAPP referenced engine operating data in relation to field engines originally
proposed in the ICCR process and not the engines at Colorado State University. Deviations from the
engine operating conditions described in the sixteen-point test matrix are referenced to the CSU
"Scope of Work". Deviation from the described engine operating conditions are as follows:
Global Deviation in Engine Operating Conditions
Speed:
The baseline speed condition was changed to 1200 rpm as indicated. This value was used for
the high speed points. The value used for the low speed points was 1000 rpm.
Air/Fuel Ratio:
The baseline air/fuel ratio condition is 28:1. This corresponds to an equivalence ratio of 0.57
and an oxygen concentration of 9.8% in the exhaust. This value was used for the normal
points. The low condition corresponds to an equivalence ratio of 0.53 and an oxygen
concentration of 10.7%. The high condition corresponds to an equivalence ratio of 0.62 and
an oxygen concentration of 8.9%.
Test Point Specific Variances
Only deviations which were not previously described in the "Global Deviation" section will
be described.
Test Point 3:
The air/fuel ratio on test point 3 appears to be wrong because it is calculated from the output
of the pre-catalyst 02 monitor. The monitor falied during this test point. The air/fuel ratio is
28:1 when the 02 is 9.8%. The catalyst outlet 02 is 9.81%, so the air/fuel ratio is correct.
Test Points 2 and 7:
The humidity system experienced a failure prior to initiation of the test point and it was
determined to conduct the test points without inlet air humidity control. The set point for
humidity ratio for all test points is 0.015 Ibs. water / Ibs. dry air. The actual humidity ratios
for Test Point 2 and Test Point 7 were 0.0126 and 0.0127 Ibs. water / Ibs. dry air
respectively.

effects of variations in humidity on engine performance and emissions.
Results from investigation into the effects of humidity on engine emissions show the *
following (Appendix S: Figure 27 - Figure 30): I
- With increasing humidity ratio, NOX emissions decrease.
- With increasing humidity ratio formaldehyde production increases. I
- With increasing humidity ratio, CO emissions decrease slightly while THC
emissions remain fairly constant. ||
- With increasing humidity ratio exhaust temperatures increase slightly, ,|
.approximately 5°F over the range of humidity ratios at the air manifold boost
pressure for Test Points 2 and 7(Appendix S: Figure 9). I
Over the range which the humidity ratio deviated from the test matrix for Test Points 2 and 7, ^
the engine emissions should be similar to engine emissions at the specified humidity ratio. |
The most dramatic effect will be on NOX emissions as can be seen from the data and the
graphs presented in Appendix S. At reduced air manifold temperatures (with engine •
operating parameters remaining constant), reduction in NOX emissions would be the most , ™
noticeable change. NOX emissions would be reduced due to the lower inlet air temperature ^
and increased inlet air density. At a constant humidity ratio, it would be expected that CH20 •
emissions would either remain constant or increase slightly with similar changes in CO and
THC emissions. •
The data collected at Test Point 2 and Test Point 7 is indicative of engine field data under
similar operating conditions. The variation in humidity ratio represents minimal impact on m
the overall emissions obtained for this data point. The most noticeable impact would be
increased NOX emissions due to changes in ambient conditions, which would result in
elevated in-cylinder temperatures and reducde heat capacity of the inlet air charge.

3.4 OTHER DEVIATIONS
The Annubar mass flowmeter used for the exhaust flow measurement did not perform correctly m
during the test program. Analysis by the manufacturer showed the unit to be properly calibrated and J
the operation of the unit was confirmed in another location on our piping system. Although the
flowmeter was installed well downstream from flow obstacles, the unit shows signs of operating in •
disturbed flow. The fuel flow measurement is the primary mass flow measurement on the system. •
The exhaust flow system was not required for the test program and was disconnected, showing a ~
negative value on the data sheets. I

4.0 TEST SAMPLING PROCEDURES
Engines & Energy Conversion Laboratory
Industrial Engine Test Facility
Colorado State University
To aid industrial,engine research, Colorado State University was commissioned to design and
install a dedicated test facility for industrial class, reciprocating internal combustion engines.
The Industrial Engine Test Facility was installed at the Engines & Energy Conversion Laboratory
to provide a mechanism by which environmental and technological issues related to industrial
class engines could be evaluated in an independent, economical and efficient manner. The
facility would also provide a level of expertise and understanding not obtainable from field-
testing.
4.1 GENERAL TEST PROCEDURES
As with any viable testing program, a procedure has been established which affords accurate and
repeatable results. The test program developed for the Industrial Engine Test Facility located at
the Colorado State University's Engines & Energy Conversion Laboratory is no exception to this
rule. Testing criteria established for the test facility ensures that the data collected has a high
degree of accuracy and can be repeated if warranted. However, since the Industrial Engine Test
, Facility was designed to allow for several different industrial engine types to be tested in a
laboratory environment, testing procedures differ somewhat from field test procedures and are
unique to this facility. The sampling procedure and calibration procedures are described under
their respective sections of the TEST SPECIFICS portion of this report.
4.2 TEST SPECIFICS-DATA COLLECTION
The data collection process has been standardized to afford accurate and repeatable results
throughout a test program. The high degree of accuracy, which can be obtained at the Industrial
Engine Test Facility, is due to the sophisticated level of instrumentation utilized at the facility.
However, without proper implementation no amount of instrumentation can assure accurate or
repeatable results, therefore a specific outline of the data collection process has been developed
for the Industrial Engine Test Facility.
Data Point Definition
A typical data point consisted of engine operating data taken over a specified time period
and averaged. During normal field operations, engine-operating parameters will fluctuate.
Variations in facility process conditions can effect-engine speed and load. Minimal control
equipment or equipment which is not specialized to provide precision control required for
engine research, can also generate unstable operation. Changes in environmental

,
conditions during the course of a test program will introduce additional unknowns into •
typical emissions field data. The Industrial Engine Test Facility was developed through an _
initiative to provide a facility which would provide accurate and repeatable data by M
reducing variations in engine operation. Under controlled conditions at the EECL,
fluctuations of engine load, speed, environmental conditions, etc. have been minimized.
This effort allows more accurate and repeatable engine data than possible with field
research programs.
I
A. standard data point collected at the EECL consists of engine operating data being
gathered over either a tkee-minute or five-minute period and averaged. It has been
determined, based on previous tests, that 3-5 minutes provides an acceptable time period
required for an appropriate data set to be collected and an average for each parameter
calculated. •
l
i
The Large Bore Engine Testbed, which has been functional since 1993, was used as a £
reference for the other test beds at the EECL. A data point at the LBET consists of 101 J
engine-operating parameters, which are collected and averaged for each data point. The
data point consists of 30 parameters which provide basic engine operating information, M
twenty parameters which are received from the emissions computer and the remaining 51 9.
parameters are engine combustion parameters calculated with a combustion analysis ^
system. For each data point an average value, minimum value, maximum value, and •
standard deviation are obtained for all engine operation and emissions parameters
collected. The combustion analyses system was not used for this test due to the lack of
sensor access ports on the Waukesha 3521 Engine.
i
For the work conducted under this test program, a test point consisted of a series of data I
points taken in succession and averaged. The data were gathered in 1-minute averages
over a 33-minute test period. Using a data set consisting of thirty-three, one-minute data M
points would highlight any large fluctuations in load and other parameters that would have ty
a significant effect on emissions data. No fluctuations in data occurred during any test
points. This demonstrated that the engine was operating at a steady condition and the data •
recorded in the individual data points was repeatable. ^
Table 5 provides information on the nominal number of samples collected under each data I
point / test run scenario for the LBET.

4.3 TEST SPECIFICS - ENGINE STABILITY
For data taken during testing to be reliable, the engine was operated in a state of equilibrium at
each test point. The engine control system allowed for engine operation data to be monitored so
that engine stability could be easily recognized. The stability of each specific engine's operation
was not only determined on a test point by test point basis, but also on a daily basis. Since
combustion parameters for each engine type will vary, engine-operating parameters were used to
determine engine stability. Procedures used for determining acceptable engine stability are as
follows:
Engine Stability: Engine Start Up Procedures
Prior to the beginning of data collection each day, the engine was "warmed up" and a
thermal equilibrium state established. This was nominally determined when the engine
coolant water systems and lubricating oil reached a steady state temperature. Once steady
state operation was achieved, a daily "baseline" data point was gathered. The length of
time required to obtain steady state operation was highly dependent upon the ambient
temperature and the temperature of the engine when started. Due to the dependence on
these factors, there was no pre-determined warm-up time.
Engine Stability: Daily Baseline Data Point
The Scope of Work for the project required that a specified number of test points be
collected on the engine. The data collection process encompassed multiple days of testing.
To ensure that the engine was operating in a similar manner on each test day, a set of
engine "baseline" data was collected. An initial set of engine "baseline" data (one five-

I
minute data point) was collected prior to the first data point. On the ensuing test days, a
"baseline" data point was collected to verify the data collection for that day. The primary m
engine operating parameters of the data point must compare to within a specified |
acceptable range of the values of the primary engine operating parameters on the original
"baseline" data set for engine stability and to the baseline operating conditions specified in M
Table 4. If primary engine operating parameters did not compare to within the *
predetermined range, corrective measures were taken to isolate and correct the cause of the ^
unacceptable values for the primary engine operating parameters. Both CSU and PES •
representatives initialized the daily "baseline" data set. All baseline data points were
acceptable during the test program. The primary/secondary engine operating parameters, A
acceptable ranges, and their nominal values for a "baseline" data set are presented above in m
Table 4.
1
i
As with the daily engine "baseline" data point, the engine must maintain a stable mode of
operation prior to and during a test run. Changing various operating parameters to achieve I
the desired test condition will cause the engine to operate in an unstable mode during the
transition period from one condition to the next. The engine parameter which has the most *
effect on engine equilibrium is engine load. Fluctuations in load will result in erratic and •
inaccurate emissions data and for this reason load was closely monitored during testing.
Changes in load will also affect the engine's thermal equilibrium and will require the I
longest time for the engine to return to a thermal equilibrium state. *••
Although the effects are not as significant as those of changing engine load, any changes in I
air manifold pressure, temperature, exhaust back-pressure, or ignition timing also affected
the engine's equilibrium. As with load changes, the engine must be closely monitored for •
return to an equilibrium state after any changes are made. Typically, the engine will return 9
to equilibrium, steady-state condition within 30-45 minutes. Prior to initiating alest run, a
pre-test run data point was gathered. The data point was five-minutes in length. For each I
pre-test run data point, an average value, minimum value, maximum value, and standard
deviation were obtained for all engine operation and emissions parameters collected. j|
Primary engine operating parameters specified at a test condition must agree with the test |
condition value within +/- 2% to +/-10% of the requested value dependent upon the engine
parameter. The relative standard deviations of the primary operating variables were below I
1.0% for engine operating parameters and below 3.0% for the engine emissions -
parameters. The primary engine operating parameters and their nominal values for a "pre-
test run" data point are presented below in Table 6.

If primary engine operating parameters did not agree with the requested test condition
values within the predetermined range, corrective measures was taken to isolate and
correct the cause of the unacceptable values for the primary engine operating parameters.
All pre-test run data points were acceptable for the test program. Both CSU and PES
representatives initialized each "pre-test run" data point.
Engine Stability: Test Run Stability
A test run consisted of a set of one-minute averaged data points taken consecutively over a
33-minute time period. For each data point, the average value for each primary engine
operating parameter must compare to within the acceptable range of the specified target
value at the test condition for engine stability and the data collection process to be valid for
the specific test condition. If primary engine operating parameters did not compare to
within the predetermined range, the data point was invalid, and corrective measures were
taken to isolate and correct the cause of the unacceptable values for the primary engine
operating parameters. •
Engine stability was maintained throughout the data collection process for each test run.
The relative standard deviation of the primary operating variables was below 1.0% for
engine operating parameters and below 3.0% for the engine emissions parameters at each
data point.
Both CSU and PES representatives initialized each data point of a test run. The tabular format of
the primary engine operating parameters, designation, and the acceptance criteria is presented in

4.6 TEST SPECIFICS - EMISSION ANALYZER GENERAL TEST PROCEDURES I
i
The following general test procedures and calibration checks guaranteed the integrity of our
sampling system and the accuracy of our data. The testing was conducted in basic accordance I
with approved Environmental Protection Agency (EPA) test methods as described in the Code of '
Federal Regulations, Title 40, Part 60, Appendix A. *
General Procedure
I
Exhaust oxygen and oxides of nitrogen concentrations from the engine were determined in basic *•
compliance with EPA Method 20, "Determination of Nitrogen Oxides, Sulfur Dioxide, and ^
Diluent Emissions From Stationary Gas Turbines"and EPA Method 7E, "Determination of I
Nitrogen Oxides Emissions From Stationary Sources (Instrumental Analyzer Procedure)". The
sampling procedure for CO concentrations was based on EPA Method 10, "Determination of
Carbon Monoxide Emissions from Stationary Sources." EPA Method 25A, "Determination of
Total Gaseous Organic Concentration Using a Flame lonization Analyzer" was the sample
procedure used to determine THC emission concentrations. A modified EPA Method ISA was •
used for the sampling procedures for Methane/Non-Methane Analysis. The method for
calculating mass emissions levels was based upon an EPA Method 19 "Determination of Sulfur
Dioxide Removal Efficiency and Particulate Matter, Sulfur Dioxide, and Nitrogen Oxides
Emission Rates" calculation. Mass emissions were also calculated using carbon balance
calculations developed by Southwest Research Institute specifically for the American Gas •
Association. Calibration and test procedures are detailed under their respective sections of the ™
TEST SPECIFICS portion of this report. . .

Sampling System
Dedicated analyzers were used to determine the NOX, CO, THC, C02, and 02 emissions
level on a dry basis for both pre and post-catalyst emissions. Dedicated analyzers were
used to determine the Methane/Non-Methane emissions on a wet basis for both pre- and
post-catalyst emissions. FTIR analyzers were used to determine aldehyde emissions on a
wet basis for both pre and post-catalyst emissions. Refer to Table 7 for the analyzers and
the methods of analysis.
Exhaust gas entered the system through a 3/8" stainless steel multi-point probe. Sample
points were located in accordance with procedures described in Method 1. Exhaust gas
then passed through a heated 3-way sample valve and glass wool filter assembly. The
sample was transported via a heat-traced Teflon sample lines and heated sample
distribution manifold. Sample for the "dry" gas analyzers then passed through a 4-pass
minimum contact condenser specifically designed to dry the sample. The "dry" sample
then entered a stainless steel sample pump. The discharge of the pump passed through 3/8"
Teflon tubing to a Balston Microfibre coalescing filter, moisture sensor, and then to the
sample manifold. The sample manifold was maintained at a constant pressure by means of
a pressure bypass regulator. A flow meter, placed in line at the exhaust of each analyzer,
monitored exact sample flows. Heated sample flow for all "wet" measurement analyzers
will be provided by means of a heated sample distribution manifold prior to sample gas
entering the "dry" gas analyzer platform. Each heated analyzer had a dedicated sample
pump and heat traced line from the main sample train to the analyzer.

Standard calibration gases with a ±1.0% or ±2.0% accuracy. For this program, EPA Protocol 1
calibration gases (RATA Class) were used. Manufacturer supplied certification sheets were •
available during the testing procedure and copies of the current inventory of gases, which were
used for calibration and integrity checks on the reference method and FTIR analyzers, are g
provided within this document. J
EPA Protocol 1 gases (Rata Class) were used to calibrate the reference method analyzers and flj
FTIR analyzers. Formaldehyde standards with a concentration range between 5 - 20 PPM were "
obtained. Acetylaldehyde/acrolein standards were also acquired. Any calibration standards
which were not EPA Protocol 1 gases were the highest quality standard available. I

Response time tests were performed on each sample system. The response time tests were •
performed prior to the FTIR validation process for each sampling system. The response time of ™
the slowest responding analyzer (Questar Baseline) was determined. Response time tests *
conducted at the EECL indicated sampling system response times of 1:10 minutes. This is the J
time for the Rosemount Oxygen Analyzer (slowest responding analyzer which continuously
monitors) to stabilize to response output of the analyzer. The Questar Baseline Industries •
CH4/Non-CH4 analyzers have a minimum cycle time of 4:50 minutes. The overall response time •
for these analyzers when their cycle is started 1:10 minutes after a sample source change is 5:50 ' —
minutes. When the CH4/Non-CH4 analyzer cycle time was initiated at a sample source change, I
the overall response time is 9:00 minutes. The response time was tested to assure that the
analyzers' response was for exhaust gas entering the sample system from each of the test point A

Calibration (Daily)
Zero and mid-level span calibration procedures were performed on the reference method
analyzer prior to each test day. Zero and span drift checks were performed upon completion
of each data point and upon completion of each test day. This procedure is referenced as
ZSD (zero and span drift check) in the CSU "Scope of Work". A zero and a mid-level gas
was introduced individually directly to the back of the analyzers before testing for carbon
monoxide, carbon dioxide, oxygen, total hydrocarbons, Methane/Non-Methane, and oxides of
nitrogen. The analyzers' output response was set to the appropriate levels. Each analyzer's
stable response was recorded. From this data a linear fit was developed for each analyzer.
The voltage for each analyzer were recorded and used in the following formula:
Y=MX+B
Where: B = Intercept
M= Slope
X= Analyzer or transducer voltage
7= Engineering Units
After each test point and upon completion of a test day, calibration checks were conducted by re-
introducing the zero and span gases directly to the back of the analyzers. The analyzers'
stabilized responses were recorded. No adjustments were made during testing or during the final
calibration check. Initial calibration values and all calibration checks were recorded for each
analyzer during the daily test program.
The before and after calibrations checks will be used to determine a zero and span drift for each
test point for the CO, C02, 02, THC, CH4/Non-CH4, and NOX analyzers. The zero and span
drift checks for each test point and each test day were less than ±2.0% of the span value (specific
range setting) of each analyzer used during the daily test program. The calibration data sheets
are presented in Appendix E of this document.
Linearity Check (Prior to initiation of engine test program)
Prior to initiation of the test program, analyzer linearity checks were performed. This
procedure is referenced as ACE (analyzer calibration error check) in the CSU "Scope of
Work". The oxygen, carbon monoxide, total hydrocarbon, methane/non-methane and oxides
of nitrogen analyzers were "zeroed" using either zero grade nitrogen, or hydrocarbon free air.
The analyzers were allowed stabilize and their output recorded. The analyzers were then
"spanned" using the mid-level calibration gases. The analyzers were allowed to stabilize, and
their output recorded. From this data a linear fit was developed for each analyzer, the
voltages for each analyzer were recorded and used in the following formula:

Using the linear fit, the linear response of the analyzer was calculated. Low level and high-level I
calibration gases were individually introduced to the analyzers. For each calibration gas, the
analyzers were allowed to stabilize and their outputs were recorded. Each analyzers' linearity •
was acceptable as the predicted values of a linear curve determined from the zero and mid-level |
calibration gas responses agreed with the actual responses of the low level and high level
calibration gases within ±2.0% of the analyzer span value. The methane/non-methane analyzers', I
linearity was acceptable as the predicted values agreed with the actual response of the low level
and high level calibration gases within ±5.0% of the actual calibration gas value. This procedure •
was performed for one range setting for each analyzer. The Linearity Check data sheets are |
presented in Appendix E of this document.
NOj Converter Check (Prior to initiation of engine test program) ™
Prior to initiation of the test program, N02 converter checks were performed. A calibration gas I
mixture of known concentrations between 240 and 270 PPM nitrogen dioxide (N(>2) and 160 to
190 PPM nitric oxide (NO) with a balance of nitrogen was used. The calibration gas mixture I
was introduced to the oxides of nitrogen (NOX) analyzer until a stable response was recorded. ™
The converter is considered acceptable if the instrument response indicated a 90 percent or •
greater NC>2 to NO conversion. The N02 Converter Check data sheets are presented in Appendix |
ijs
E of this document.
Sample Line Leak Check (Prior to initiation of engine test program)
I
The sample lines were leak checked before the engine test program. The leak check procedure m
was performed for both pre-catalyst and post-catalyst sample trains. The procedure involved
closing the valve on the inlet to the sample Filter located just downstream of the exhaust stack •
probe. With the sample pump operating, a vacuum was pulled on the exhaust sample train. Once
the maximum vacuum was reached, the valve on the pressure side of the pump was closed thus •
sealing off the vacuum section of the sampling system. The pump was turned off and the J
pressure in the sample system was monitored. The leak test was acceptable as the vacuum gauge
reading dropped by an amount less than 1 inch of mercury over a period of 1 minute. The •
Sample Line Leak Check data sheets are presented in Appendix E of this document. *

Sample Line Integrity Check (Daily)
A sample line integrity check was performed prior to and upon completion of each test day. This
procedure is referenced as SSB (Sampling System Bias Check) in the CSU "Scope of Work".
The analyzer's response was tested by first introducing the mid level calibration gas directly to
the NOX analyzer. The analyzer was allowed to stabilize and the response recorded. The same
mid level calibration gas was then introduced to the analyzer through the sampling system. The
calibration gas was introduced into the sample line at the stack, upstream of the inlet sample
filter., The analyzer was allowed to stabilize and the response recorded. The analyzer response
values were compared and the percent difference did not to exceed ±5 % of the analyzer span
value (range setting).
The SSB procedure was to be performed for both the NOX and methane/non-methane analyzers.
It was determined to perform the integrity check for the NOX analyzers only. The SSB procedure
was performed for the methane/non-methane analyzers prior to and upon completion of the test
program. The Sample Line Integrity Check data sheets are presented in Appendix E of'this
document. .
Carbon Balance Check (Continuous)
One of the methods used to calculate mass emissions was a carbon balance calculation developed
by Southwest Research Institute specifically for the American Gas Association. As part of a QC
check, the calculations involve performing a theoretical 02 calculation based upon measured
exhaust stack constituents and fuel gas composition. The theoretical exhaust 02 is then
compared to the measured exhaust 02. The percent difference between the actual and theoretical
02 measurements was within ±5 % of the measured 02 reading. The 02 balance was performed
for every one-minute average and the thirty-three minute averaged value for sach test point. The
averaged value for each test point is included in the test point data in Appendix A.
Fuel Gas Analysis & Fuel Flow Measurements
Natural Gas Fuel Gas:
Engine fuel gas was analyzed on a real time basis with a dedicated Daniels Industries
GC. The GC was calibrated on a daily basis against a known standard. A daily gas
analysis was acquired for each test day. This analysis gave the actual specific gravity,
mole fractions of specific hydrocarbons and BTU content so that fuel flow and mass
emissions could be accurately calculated. Fuel flow measurements were made using an
AGA specified orifice meter run equipped with dedicated high accuracy pressure and
temperature transmitters. All fuel flow calculations were in accordance with AGA

Each unit and the associated test method have been designed for measurement of raw exhaust
gases from internal combustion engines. Dedicated temperature controllers maintained cell
temperature and associated sample lines at the appropriate the design temperature. Pressure was
controlled by means of an MKS pressure controller for each system. Sample flow to each
analyzer was between 8-15 liters/minute. The units utilized a high-energy mid-range IR source
and are equipped with modulating, potassium bromide beamsplitters with MCT-A liquid nitrogen
cooled detectors. The cells have been equipped with specific optical windows to prevent signal
degradation from damaged optics due to moisture and corrosive gases present in the exhaust
stream.
Pre Engine Test Calibration
Prior to initiation of an engine specific test program, the FTIR sampling systems, both pre and
post-catalyst sample trains underwent an EPA Method 301 validation process. The validation
process was to verify the sample and analytical system performance in relation to precision and
accuracy of data collected. Additional calibration procedures prior to testing of the engine were
as follows:

1.) Source Evaluation - Acquired initial source data to verify concentration ranges of target «
compounds and possible interferants. This was accomplished prior to and during the |
Method 301 validation process
2.) Sample System Leak Check -Sample system leak checks were performed. The leak I
check procedure encompassed the sample train from the sample filter to the pump outlet. ™
A dedicated ro'tameter was installed on the discharge side of the sample pump. With the «
sample system operating at typical temperatures and pressures (sample pump will pull a |
slight vacuum on the suction side), the sample flow rate from the rotameter was
recorded. The inlet to the sample filter located just downstream of the sample probe was •
closed and the flow rate through the rotameter was monitored. The flow rate through the «
rotameter went to zero. The leak checks were determined to be acceptable, as the leak
rate was less than 4% of the standard sampling rate or 500ml/min, whichever is less. I
Sample system leak check data sheets are provided in Appendix F of this document.
3.) Analyzer Leak Check - With the FTIR analyzers operating at normal operating
temperatures and pressures, the operating pressures were recorded. The automatic
pressure controllers were then disabled, and the inlet valves to the FTIR analyzers were
then closed. The measurement cells were then evacuated to 20% or less of their normal I
operating pressure. After the measurement cells were evacuated, each measurement cell
was then isolated and the cell pressure monitored with a dedicated pressure sensor. The m
leak rate of each measurement cell was less than 10 Torr per minute for a one-minute £
period. The analyzer leak rate was determined to be acceptable. Analyzer leak check
data sheets are provided in Appendix F of this document. • I
4.) Cell Pathlength Determination - The cell pathlength was to be determined using the *
measurement procedures as outlined in the Field Procedure Section of the document ^
entitled "Protocol For Performing Extractive FTIR Measurements To Characterize I
Various Gas Industry Sources For Air Toxics", prepared by Radian International for the •
Gas Research Institute. Because the units are fixed pathlength (non-adjustable) •
measurement cells which are stationary units dedicated to a specific task, the pathlength »
determination process was determined not to be necessary. The units are "as specified"
from the manufacturer, and have passed all validation and calibration procedures at this I
fixed pathlength.

Daily Calibration Procedures - Pre Test
The following daily calibration procedures were performed prior to the initiation of each day's
testing. . • .
1.) Instrument Stabilization - To ensure the FTIR instruments were operating in a stable
manner, verification of the operation of the following components at the beginning
of each day was performed:
a.) All instrument heated devices and temperature controller were at operating
temperature and performing properly.
b.) Pressure sensor and pressure controllers were at operating conditions and
performing properly.
c.) Sample systems (pumps, filters, flow meters, and water knockouts) were
functioning properly.
2.) Instruments were operated on a conditioned air source for a minimum of 30 minutes
prior to conducting background spectrum procedures. When the instruments were in
standby mode, between test days, the analyzers and all components were kept at
normal operating, temperatures. The analyzers operated on conditioned air at all
times when not involved with data acquisition.
3.) Background spectrum procedures - After purging with a conditioned air source for a
minimum of 30 minutes, the instruments were allowed to stabilize by flowing an
ultra high purity N2 gas through the measurement cell for a minimum of ten minutes.
During the stabilization process, the FTIR spectra were monitored until the
concentrations of CO and H20 were reduced and normal steady state background
levels had been achieved. The following procedures were then performed:
a.) Check for proper interferogram signal using alignment software
b.) Collect a single beam spectrum and inspect for irregularities
c.) Check the single beam spectrum for detector non-linearity and correct if
necessary
d.) Perform an instrument alignment procedure
e.) Collect a background spectrum - The background spectrum was comprised -256
scans, which was equal to or greater than the number of scans used for sample
analysis.
4.) Analyzer Diagnostics - Perform an analyzer diagnostic procedure by analyzing a
diagnostic standard. The standard was a EPA Protocol 1 CO gas standard at
concentration levels indicative of the emissions source, 109 ppm. A CO standard
was recommended due to the distinct spectral features, which are sensitive to
variations in system operation and performance. The standard was introduced
directly into the instrument: The instrument readings were allowed to stabilize and a

five-minute set of data was acquired. The calculated accuracy and precision based
on equations from the document entitled "Protocol for Performing Extractive FTIR •
Measurements To Characterize Various Gas Industry Sources for Air Toxics", |
prepared by Radian International for the Gas Research Institute, was acceptable. The
pass/fail criteria for accuracy and precision was ± 1 0% of the known standard for the I
instrument to be acceptable. Each instrument meets this criteria for all daily
calibrations. Analyzer diagnostic data sheets are provided in Appendix F of this m
document. |
5.) Additional Analyzer Diagnostic - An additional diagnostic check was performed to
ensure system operation and performance. A second diagnostic standard comprised •
of a multi-gas composition was analyzed by the same procedure. The gas consisted ™
of C02, CO, CH4, and NOX in concentrations similar to exhaust gas composition. ^
The same pass/fail criteria was used to evaluate each analyzer's performance when I
analyzing the multi-gas standard. Each instrument meets this criteria for all daily
calibrations. Analyzer diagnostic data sheets are provided in Appendix F of this Mj
document. ™
6.) Indicator Check & Sample Integrity Check - An indicator check procedure was
performed on each analyzer by analyzing a certified indicator standard. The standard I
was either a NIST traceable, EPA Protocol 1 gas standard, or highest grade standard
available of a surrogate/analyte gas concentration at levels indicative of the
emissions source. A formaldehyde standard (concentration of 10.66 ppm) was used
due to the fact that formaldehyde represents a sampling challenge because of its
solubility in water. The standard was introduced directly into the instrument. The I
instrument readings were allowed to stabilize and a five-minute set of data was
acquired. Next, the indicator standard was introduced into the sample system at the *
sample filter located just downstream of the sample probe. The instrument readings £
were allowed to stabilize and a five-minute set of data was acquired. The calculated
accuracy and precision based on equations from the document entitled "Protocol For •
Performing Extractive FTIR Measurements To Characterize Various Gas Industry ™
Sources For Air Toxics", prepared by Radian International for the Gas Research ^
Institute. The pass/fail criteria for accuracy, precision, and recovery was ± 10% of I
the known standard ( recovery was ± 10% of the instrument reading with the
indicator gas introduced directly into the instrument.) for the instrument to be •
acceptable. Each instrument meets this criteria for all daily calibrations. Indicator •

Daily Calibration Procedures - Background assessment
The baseline absorbance was continually monitored during data acquisition procedures. If it was
determined by PES, ERG, and CSU personnel that the baseline had changed by more than 0.1
absorbance units, the instrument interferometer was realigned and a background spectrum
collected.
Daily Calibration Procedures - Post Test
Upon completion of the daily test program steps 4-6 of the pre test calibration procedures were
repeated. Both analyzers meet all acceptance criteria for calibration procedures. All post test
calibration data sheets are presented in Appendix F of this document.
4,9 TEST SPECIFIC - FTIR VALIDATION PROCEDURES
To ensure the accuracy of data collected during testing, the test program required procedures to
evaluate instrument performance. Prior to collecting test data, a validation procedure was
performed on each FTIR sample train, both pre-catalyst and post-catalyst, for the natural gas
fueled engine classification. The specific sample trains are as follows:
1.) Pre-catalyst emissions sample trains from the exhaust of natural gas fueled engines.
This comprises the two-stroke lean bum engine class and four-stroke lean burn
engine.
2.) Post-catalyst emissions sample trains from the exhaust of natural gas fueled engines.
This comprises the two-stroke lean burn engine and four-stroke lean burn engine.
Each sample train was validated for the following target compounds:
1.) Formaldehyde
2.) Acetaldehyde
3.) Acrolein

Procedures
I
Eastern Research Group, ERG, performed the validation for the target aldehyde compounds. The
validation procedure was conducted in basic accordance with procedures outlined in Method I
301-"Field Validation of Pollutant Measurement Methods from Various Waste Media".
Validation procedures for aldehydes utilized an analyte spiking technique as specified in Method m
301. The procedures for the validation process are as follows: |
Analyte Spiking: •
The process was carried out by means of dynamic analyte spiking of the sample gas. The ™
sample stream of the exhaust gas was spiked with the specific analyte after the sample . ^
probe, and before the sample filter. Spike levels for the specific aldehydes were |
determined and the spike gas concentrations were generated for the specific aldehydes
using the following methods: flj
Formaldehyde:
Formaldehyde spike gas was generated by volatilization of a formalin solution I
prepared from a stock formalin solution of 37% formaldehyde by weight. The
solution was injected into a heated vaporization block. The vaporized formalin
solution was mixed with a acerylaldehyde/acrolem carrier gas and carried into the
sample exhaust stream. Carrier gas flow rate was measured by a mass flow meter
equipped with readout I
i
Acetlyaldehyde/Acrolein: •
Acetlyaldehyde and acrolein spike samples were generated from a certified gas |
standard (Scott Specialty Gases, ±2% analytical accuracy) which contained both
' analyte species and a sulfur hexaflouride (SF6) tracer gas. Carrier gas flow rate was I
measured by a mass flow meter equipped with readout. *
sample system filter. The spike gas was introduced at a known flow fate. The spike gas
flow was controlled by a three-way solenoid valve, which directed gas either into the •
sample stream or diverted the spike gas to the atmosphere. This allowed for •
uninterrupted flow of the analyte spike gas source during the validation procedures.
I
The formaldehyde and acetylaldehyde/acrolein validation runs were conducted
simultaneously. The validation test runs consisted of 24 test runs, 12 spiked and 12 •
unspiked runs, which were paired and grouped further into six groups of 2 |
spiked/unspiked pairs to simulate the "quad train" approach used for Method 301

statistical calculations. Samples were one minute in duration. Measurement procedures
for acquiring the spiked/unspiked pairs are as follows:
1.) Verify stable engine operation
2.) Begin measurement of the unspiked native exhaust stack gas.
3.) Upon completion of acquiring the unspiked sample, initiate spike gas flow into
sample stream.
4.) Let system equilibrate.
5.) Begin measurement of the spiked exhaust gas sample.
6.) Upon completion of acquiring the spiked sample, divert spike gas flow to
atmosphere.
7.) Let system equilibrate.
8.) Repeat items 2 through 7.
This procedure was performed twelve times to acquire the appropriate number of
spiked/unspiked pairs. To ensure stable engine operation during the validation
procedure, engine operating data was collected during the spiking process.
4.10 TEST SPECIFIC - GENERAL CALIBRATION
To ensure the accuracy of data collected during testing, the test procedure required that all
instrumentation be routinely calibrated. Calibrations and/or calibration checks were performed
within one week before initiation of testing, and upon completion of the entire test program to
ensure that no "drift" has occurred. The devices calibrated included the dynamometer 5000-lb.
load cell and amplifier, all thermocouples, pressure transducers, and all pressure transmitters.
Dynamometer Load Cell and Amplifier (DaUy)
The 5000 pound load cell and amplifier was calibrated prior to. the engine test section. The
calibration procedure is outlined in a document contained in Appendix M of this document.
Calibration of the load cell and amplifier were then be verified by applying the full range of load
without any adjustments to the offset or gain of the instrumentation. Calibration checks were
performed on a daily basis prior to starting, the engine to identify and correct any drift in the load
cell or amplifier. These checks used the same procedure as the calibration verification. If the
daily calibration check showed an indicated load that exceeded ±1.0% of the torque applied by
the standard weights, the full calibration procedure was performed. The dynamometer was
within acceptable limits during the test program. Dynamometer calibration data sheets are
provided in Appendix L of this document.

Thermocouples (Within one week prior to initiation of each engine test program)
K-type insertion thermocouples are used throughout the Large Bore Engine Testbed with |
compensation performed through the engine control and data acquisition hardware. The
thermocouples were calibrated using a Ronan X88 portable calibrator calibrated within ±1.0°F of •
N.I.S.T. standard by an independent laboratory. The thermocouple signal was zeroed and the *
gain adjusted at full span until the value displayed by the NetCon 5000 matched the setting of the ^
Ronan X88 within ±2.0°F. Once the zero and gain have been set a minimum of two mid-point |
temperatures were checked to verify the calibration. Thermocouple calibration data sheets are
provided in Appendix! of this report. •
Pressure Transducers (Within one week prior to initiation of each engine test program) ^
A 3-way valve has been installed to allow pressure transducer calibration without removing the
sensor from the system. The Model 320 Beta calibrator used for transducers calibration provides . •
an accuracy of 0.05% of reading or 0.02% of full span and is calibrated to N.I.S.T. standards by I
an independent laboratory. The transducer was zeroed and the gain adjusted at full span until the

implemented. Although ominous the task of meeting compliance, difficulties involved in
complying with tightening emissions regulations have advanced the knowledge and
understanding of engine emissions and perjbrmance. The mechanism, which has elevated the
understanding of exhaust emissions, is research and development. To aid in this effort the
Engines & Energy Conversion Laboratory was established at Colorado State University. The
engines located at the Engines & Energy Conversion Laboratory (EECL) located at Colorado
State University, and are representative of the types used by the oil and gas industries as well as
power generation markets. The CSU facility currently comprises the only independent large-
bore industrial engine test facility in North America. Engines that are located at the facility are
as follows: .
• Cooper -Bessemer GMV-4-TF, Two-Stroke Lean Bum Natural Gas Fired
Engine
• Waukesha 3521GL, Four-Stroke Lean Burn Natural Gas Fired Engine
• White Superior 6G825, Four Stroke, Rich Burn Natural Gas Fired Engine
• Caterpillar 3508, Four Stroke, Lean Burn Diesel Fueled Engine
The natural gas pipeline industry has supported the installation of three four-stroke engines in the
same manner as the original engine installation. The program sponsor for the installation of the
engines is the Gas Research Institute (GRI). The additional engines have been installed at the
facility to assist research efforts in addressing needs, both emissions and performance related, on
multiple engine types. The high-speed, four-cycle, industrial engines (approximately 1000-1800
rpm) represent a large portion of the current horsepower in operation within the oil and gas
industry and power generation markets.

1.0 EXECUTIVE SUMMARY
An independent verification of the Fourier Transform Infrared (FTIR) system at
Colorado State University (CSU) Engine and Energy Conversion Laboratory-(EECL) was
conducted on 16 and 17 January 1997. The verification test was performed on the CSU
FT3R system for formaldehyde, acetaldehyde, and acrolein utilizing the validation test
procedures according to EPA Method 301. The sample matrix measured in the system
evaluation was exhaust gas from the natural gas-fired Cooper GMV 2-cycle large-bore
internal combustion (1C) engine operated under lean combustion conditions located at the
EECL facility.
The CSU FTIR system met the EPA Method 3 01 validation criteria for all three
analytes (i.e., formaldehyde, acetaldehyde, and acrolein). Relative standard deviation was
significantly less than the Method 301 precision criteria of 50 percent in all cases and
measurement bias was statistically insignificant for formaldehyde and acetaldehyde. The
results indicate that no bias correction factor for formaldehyde and acetaldehyde is
required. However, the acrolein data generated using the CSU FTBl system must be
multiplied by a bias correction factor of 0.96 before subsequent use. Table 1-1
summarizes the results of the CSU FTIR system verification.

2.0 INTRODUCTION
I
I
Radian International, LLC was retained by Enginuity International, Inc. to conduct •
an independent verification of the CSU EECL FTIR system using EPA Method 301 •
validation procedures. The verification testing was conducted for formaldehyde, H
acetaldehyde, and acrolein in exhaust gases generated from natural gas-fired 1C engines. •
The verification testing of the CSU FTIR system was essentially identical to that used in _
the EPA-approved validation tests performed by Radian for the Gas Research |
Institute [1]. The verification testing was conducted at the CSU site during 16 and
17 January 1997. |

The following procedure was used for generation of spiked and unspiked samples:
• Measure native stack gas for a 5 minute period;
• Start spike gas flow into sample stream;
• Let system equilibrate for 5 minutes;
• Measure spiked sample stream for 5 minutes;
• Turn off spike gas flow;
• Let system equilibrate for 5 minutes; and
' • Repeat cycle.
This cycle is repeated 12 times to provide 12 spiked/unspiked pairs. These pairs were
grouped further into six groups of 2 spiked/unspiked pairs to simulate a 'quad train'
approach used for the Method 301 statistical calculations.
Spike level was computed from mass balance for formaldehyde, and by dilution
measured from the SFg dilution tracer for acetaldehyde and acrolein. The equations for
computing spike level can be easily derived or can be found in the GRI FUR validation
report [1].

4.0 RESULTS AND DISCUSSION . I
Tables 4-1,4-2, and 4-3 present the CSU FTIR system verification results for •
formaldehyde, acetaldehyde, and acrolein, respectively. These tables are taken directly •
from the Method 301 validation spreadsheet available from the EPA EMTIC electronic „
bulletin board. Verification test data were grouped into 'quad train' sets to facilitate the |
use of the EPA spreadsheet. As previously summarized in Table 1-1, the CSU FTIR
system met the EPA Method 301 validation criteria for all three analytes (i.e., |
formaldehyde, acetaldehyde, and acrolein).
As indicated in Table 4-1 through 4-3, all three analytes were well within the
Method 301 precision criteria of 50% RSD. The highest RSD observed is 12 percent for |
the unspiked acetaldehyde validation. Acrolein unspiked data were set to zero since •
acrolein was not detected in any of the unspiked validation runs. Formaldehyde and «
acetaldehyde do not show any statistically significant bias, while acrolein shows a small I
but statistically significant bias of + 4 percent. This is easily 'within the Method 301
criteria of +/- 30 percent bias. As a result, formaldehyde and acetaldehyde data from the |
CSUEECL FTIR system do not require any bias correction, while acrolein results should
be multiplied by a bias correction factor of 0.96 before final use. |
Table 4-4 presents the calibration data for all flow measurement devices used in |
the study. As indicated, the difference between pre- and post- validation calibrations is
less than 4 percent in all cases. •

1 Make sure programmed PAL chip is in position U3 on the Auto Ignite board.
2 Adjust the voltage at test point 1 to 3.00V with P1.
3 Attach auto ignite test fixture to test points 1-12.
4 Adjust P2 until diode 10{occilation frequency) turns on every 10 seconds.
5 Turn unit off, then on to reset. Diodes 6-9 on the test fixture should step
through a binary count sequence, with diode 4(coil on) lighting every other step.
6 Diode 5(H2 Shutoff) should remain lit until a binary count of 10.
Afterwards, diode 5 should respond to the front panel H2 ON/OFF switch
and diode 4(coil on) should respond to the Ignite button.
7 Short terminal 7 on the back panel to ground. The sequence should reset.
I SAMPLE PUMP SETUP
1 Turn on the pump with the front panel switch.
2 Check that the fittings and lines are not vibrating against the case as they
pass through the oven wall.

L FLOW CALIBRATION
1 Attach H2 and HCF Air to their respective inlets on the back panel.
Bottle pressure should be 40PSI in both cases.
Note: It is common to "T" the Air line to provide pressure for both the
combustion Air inlet and the SP (valve actuation) inlet.
2 Attach a flow meter to the outlet side of the built in H2 regulator.
Adjust the pressure until a flow of 40 cc/min is obtained.
3 Attach a flow meter to the outlet side of the Air regulator.
Adjust to pressure until a flow of 200cc/min is obtained.

Calibration
Check zero with no weights or calibration arm. If it is a couple units or more offj
set toggles to zero, press, and hold Auto Zero button on DynLoc controller for one
second.
Record reading.
Put on calibration arm and first weight. Let it settle and record reading.
Repeat for next five weights.
Put on last weight (there will be one weight not used) and let it settle. If it is a
couple units or more off, set toggle switches to 4984, press, and hold Auto Span
button on DynLoc controller for one second.
Record reading.
Remove weight; let it settle, and record reading.
Repeat for next six weights.
Remove calibration arm.
Average loading and unloading calculated torque. Calculate % actual torque as
per calibration sheet
All should be within one % of actual torque. If not, recalibrate.

ABSTRACT
Alternative fuels, catalytic converters, and high scavenging ratios
necessitate refined approaches toward calculating air/fuel ratio from
measured exhaust composition. Computation methods were developed
for most of the situations encountered, including a method based on
oxidation potential for use in catalyst applications. The methods
developed, along with the technical basis and derivations, are
provided in this paper.
INTRODUCTION
This is the third in a series of technical papers involving emissions
' related computations for alternative fuels. The two previous papers
by Urban et al (1992 and 1993)-involved hydrogen and natural ;gas
engines. The subject of this paper is the computation of air/fuel ratio,
from exhaust composition, for combustion of any carbon-containing
fuel. Computations provided in this paper were developed as a result
I of specific needs within the laboratory of the authors. It is hoped that
providing these computations will save others from having to go
through the mathematical derivation exercise, when the need arises in
their activities.
I Over the past almost 100 years^ there have been several periods of
development of air/fuel ratio calculations. The most recent extensive
development was in the 1960s, which is considered exemplified by
the "landmark" technical paper by JSpindt (1965). With the wide-
spread use of alternative fuels and personal computers, further
development of APR calculational methods has again become both
essential and practical. Any who are interested in the history of the
development of air/fuel ratio calculations are referred to a technical
paper of a few years ago by Uyehara(1991), which contains
numerous pertinent references.
DERIVATION APPROACH
After a brief review of previous efforts toward developing air/fuel
ratio (APR) calculations for alternate fuels, the decision was made to
begin with the basic combustion equation and to include as many of
the potential fuel and exhaust constituents as practical in developing
standard 'APR computations. • Another approach involved
determination of an "oxidation potential" for use when the APR is
very near stoichiometric. It was also decided that no laboratory effort
would be conducted in this endeavor, and that the literature would be
relied on to provide a suitable water-gas equilibrium constant
In this paper, multiplication will be designated by an asterisk (*)
and division will be designated by an oblique line (/). Rather than
have a list of definitions to which the reader must continually refer,
an attempt has been made to minimize the number of terms and
identifiers requiring definition, and to provide necessary definitions
at the point where needed.

Water-Gas Equilibrium Constant
At the present lime, water and hydrogen are not measured in the
exhaust. The hydrogen (H2) concentration is related to the
concentrations of carbon monoxide (CO), carbon dioxide (C02), and
water (H20) as follows:
CO, + H, ±5 CO + HiO
M £ ••
Extent of reaction is defined by the water-gas equilibrium constant (k)
defined as follows:
k « CO«H,0 / C02*H,
An initial question is whether k is really a constant. The answer
appears to be that k is not an actual constant, and an absolute value
for k is not known and For practical purposes, however, the value of
k Is adequately known and sufficiently constant to enable acceptable
computation of APR.
Reported values for k have ranged from a low of 3 to a high of 4,
but the predominant accepted value appears to be 3.5. First, let us
look at the effect of variation in the value of k on computed APR.
The error in calculated APR with variation in k is approximately as
follows:
% Error in AFR - 0.0025«((% Variation in k)*(Exh %CO)*HCR]
Where: HCR a Fuel Hydrogen to Carbon Ratio
(Atoms of H per atom of C)
Even taking a worst case of ten percent variation in k, ten percent
CO in the exhaust, and a fuel HCR of 4, the error in computed AFR
would only be a relatively insignificant one percent. Therefore, the
predominantly-used value for k of 3.5 will be used in developing the
computations in this paper.
It should be pointed out that the value of k could change1 when a
catalyst is being used, because the activity of the catalyst on CO and
Hj can differ, and the resulting concentrations may not equilibrate.
Error in calculated AFR would generally be insignificant, however,
because with a catalyst in the exhaust stream, concentrations of CO
and H2 will generally be low.
Combustion Equation
Based on review of numerous equations over the years, the
usefulness of meaningful variable names has been well established.
In this paper, fuel components will be expressed as atoms and exhaust
constituents will be expressed as molecules. The generally used x, y,
and 2 for the fuel components of carbon (C), hydrogen (H), and
oxygen (0) will be retained, and an "f" will be used for all other
components of the fuel. Variable names for exhaust constituents,
Other than oxygen (02), will be the first letter of the last word in their
names (e,g., d for C02, n for oxides of nitrogen (NOX), w for water
(H20), etc,), A T, rather than an "o", is used for exhaust 02, to
eliminate possible confusion between the letter "o" and zero, and-an
HAH is used for air (rather than an "a").
Therefore, to follow the equations in this paper, it will only be
necessary to memorize the variables designated by "f" and "t" and to
remember the process used in naming the other variables. Also, in an
attempt to make the equations less confusing, from this point forward.
subscripts will not be used (e.g., C02 = C02, H20 = H20, etc).
The combustion equation is as follows:
FUEL + AIR -» EXHAUST (1)
FUEL = xC + yH + zO + fN
AIR = A02 + [3.7742*A]N2
EXHAUST = cHC + mCO + hH2 + dC02 + nNOX
+ wH20 + t02 + (3.7742«A -0.5n]N2 + fN
The fuel components are to include all of each component.
regardless of the source (e.g., the C and the 0 for gaseous fuels
include that from the C02), and the N is to include all components
that are not C. H. or 0. Initially, let X equal 1; then y becomes the
hydrogen- to-carbon ratio (HCR), and z becomes the oxygen-to-
carbon ratio of the fuel (on a per atom basis). Note that the N2 in the
"AIR" includes all of the constituents of air, other than oxygen., as
given on Page F-155 of the CRC Handbook (1988). Also, the oxides
of nitrogen (NOX) are considered to be nitric oxide (NO), because the
ratio of NO to N02 is generally unknown, and the majority of the
NOX is generally NO in raw exhaust.
COMPUTING STOICHIOMETRIC AFR
For stoichiometric combustion (c, m, h, and t = 0, w = 0.5 y, and
n set = 0), the AFR can be determined as follows:
SAFR = [A*(MWm +3.7742*MWN2)]
/ (AWc + y*AWH + z*AWo + f*AWn]
Where: A = 1 + 0.25y - 0.5z
Note: MW is molecular weight and AW is atomic weight
Using the preceding value for A and inserting the molecular and
atomic weights, the SAFR is as follows:
SAFR
Notes:
(1 + 0.25y - 0.5zH31.999 * 3.7742*28.159)
12.011 + 1.008y + 15.999z + 14.007f
• The MW of 28.159 given for N2 is the average MW for
all of the components in air, other than oxygen.
• If some additional fuel constituent other than the N is
present in significant quantity, use a corrected AW
in place of the 14.007 .
SAFR =
138.28»(1.0 * 0.25y - 0.5z)
12.011 + 1.008y + 15.9992 + 14.007f

COMPUTING COMBUSTION APR
This section of the paper describes the approach taken and provides
the basic criteria applied toward computation of the combustion
air/fuel ratio (APR). The derivations of the equations for computing
the APR are given in the attachment to this paper. In essence, the
computation requires deriving the value of variable "A" from the
exhaust constituents. This would involve a rather simple exercise if
the concentrations of all exhaust constituents were known. Such is
not the case, however, because the amounts of hydrogen and water
from combustion are not generally measured, and at times oxygen is
not measured. The APR calculated is for dry air (does not include
humidity). To compare the results to an APR calculated from
measured fuel and air, the water vapor in the intake air must be
mathematically subtracted from the APR derived from measured fuel
and air or added to result derived from measured exhaust constituents.
Initial Conversion of Input Data
Initially all fuel and exhaust composition data must be converted
into consistent units. Assuming fuel components are input, as mass
fractions of the total fuel (i.e., Total Fuel =1), the conversions to
number of atoms of a fuel constituent per atom of carbon (or moles
per mole) are as follows:
FUEL FACTORS: (3)
• x = (FFC/FFC)*( 12.011/12.011) for carbon
y = (FFH/FFC) * (12.01 II 1.008) for hydrogen
z = (FFO/FFQ* (12.011/15.999) for oxygen
f =. (FFX/FFC) * (12.011/AAWX) for all other
FF = Fuel Fraction
AAW = Average Atomic Weight (Use 14.007 ifN or unknown)
Use total C, H. and 0 - including that in C02, H20. etc.
For the exhaust constituents, all measured concentrations must be
expressed in percent on a dry basis. Additionally, the C02
concentration must be corrected for background (BG), and the HC
concentration must be corrected for FID response. Equations for
performing the necessary conversions are as follows:
CONVERSION EQUATIONS: (Exhaust Constituents) (4)
Measured Dry (dew point less than -30°C):
Dry %XX = Measured %XX
Measured Ice-Trap Dry (dew point 0°C to 2°C):
Dry %XX = (Measured %XX)»1.0068 :
Note: Following equations include constants derived empirically by primary author.
Measured Wet (no water removed from sample):
Dry%XX * Wet%XX*[(100 +H20FAC +HUMFAQ/100]
H20FAC = 0.005*y*%C02 + 0.005*y*%CO
- 0.01 *y*SAFR*[%CO +0.0121 *(%CO)16]
HUMFAC <= 0.168*HUM
(HUM s Intake humidity in grams/kg of dry air).
C02 Corrected for Background C02: •'-
%C02 ~ Measured %C02 - I.1*BG%C02

. • tiC Corrected for FID Response:
%HC = Measured %HC / FID Response Factor
If unknown: FIDRF « {0.87 +0.07*y -0.33*z]
Balance Equations and Water-Gas Ratio
Three balance equations can be generated from the combustion
equation. The equations (for carbon, oxygen, and hydrogen) are:
BALANCE EQUATIONS:
Carbon Balance:
1 = c + m -fd (When x = I )
Oxygen Balance:
0.5z + A = 0.5zc + 0.5m + d + 0.5n + 1 + 0.5w
(5)
Hydrogen Balance:
0.5y = 0.5yc + h + w
w = 0.5y - O.Syc - h
The water-gas ratio for determining exhaust H2 from measured
exhaust constituents is as follows:
k = 3.5 = [CO»H20] / [H2*C02] = [m«w] / [h*d]
Substituting for "w" and solving for "h" provides:
h = [0.5m(y-c)]/[3.5d + m] (6)
Relating Variables To Concentrations
The next requirement is to define the variables in the combustion
equation in terms of the measured values for the exhaust constituents.
This can be done in the form of ratios, as follows:
c/c = %HC/%HC m/c = %CO/%HG d/c = %C02/%HC
i
Then substituting into the carbon balance equation:
1 = c(%HC/%HQ + c(%CO/%HC) + c(%C02/%HC)
c = %HC / (%HC + %CO + %C02)
Solving all of the other variables in terms of the measured exhaust
constituents, in like manner, provides the following:
VARIABLES IN TERMS OF CONCENTRATIONS:
(7)
c = %HC
m= %CO
d = %C02 / (%HC + %CO + %C02)
n = %NOX/(%HC +
t = %02
Solution of APR Equation
At this point, all of the necessary conversions have been defined and
all of the necessary equations have been developed to enable deriving
the equations for computation of APR. It onlv remains to carry the
resolution to a final solution.
Initially, an attempt was made to use the computer to effect the
solution, but no available program was capable of solving the
numerous simultaneous equations. Therefore, the solution was
derived manually. The solution is included in Appendix A to the
extent practical.
-------
EQUATIONS FOR CALCULATING APR AND LAMBDA
Computations of APR and Lambda (X) have been developed for
coses in which:
• All exhaust constituents are measured;
* All exhaust constituents, except oxygen, are measured;
«Oxygen is the only exhaust constituent measured.
Lambda is the combustion APR divided by the stoichiometric APR.
In the definition of lambda, the 0 in the exhaust NO is effectively
taken as being available oxygen. With three-way catalyst systems,
the NO is the source for the oxygen involved in oxidizing the CO .
Basic equations for calculation of APR and X are as follows:
APR
138.28«A
12.011 + 1.008*y + 15.999«z + 28.016»f
X sAFR/SAFR
(8)
(9)
Derivations for most, and the computations for all. of the variables
(except "A") are provided in the text of this paper. Derivations for
MAM are more involved and are provided only in the attachment. In
these applications, exhaust H2 concentration is computed (identified
as H2FAC) as follows;
H2FAC
- %HC]
3.5»%C02
„„
All Exhaust Constituents Available
Por the situations in which all exhaust constituents are measured,
and it can be assumed that C02 and 02 are both measured with equal
accuracy (accuracy as a percent of the measured value), the measured
values of both are included in the computation. In situations where
the 02 measurements are significantly less accurate than the C02
measurements, use the computation in the next section, in which an
02 value is effectively derived from the measured C02. The
equation for computation of "A" when the measured C02 and 02 are
considered to be equally valid is as follows:
[(0>z-0.25«y)*%HC + 0.5*%CO + %C02
+ 0.5'NOX + %02 - 0.5-H2FAC]
/ (%HC+%CO+%C02] +0.25*y -0.5*z
(U)
Oxygen Balance Computation
An oxygen balance computation (02BAL) has been developed to
indicate accuracy of the measured exhaust C02 and 02r when both
are measured, In this process, an 02 value is calculated from the
other exhaust constituents, and that calculated 02 value is compared
to the measured 02 value. Derivation of the balance computation is
as follows:
.1
02BAL « P02 - CAL02)*100.]
/ [(A + 0,5«z)*(%HO%CO+%C02)]
CAL02 « [Calculated t] * [%HC+%CO+%C02]
02BAL-
t*100.]
A+0.5*z
Calc! t = [20.946/(%HC+%CO+%C02)]
- [(0.2095 -0.1976y +Q.393z)c - 0.6047m
+ 0.1858H -d -0.5n -0.1976y +0.3953z -0.2095f]
The result in percent is defined as the difference between the
measured 02 and the value 02 should be, assuming measured values
of other exhaust constituents (primarily C02) were exactly correct.
In general, when the 02BAL value is significant (the primary author
usually uses a limit of two percent), either the 02 or the C02
measurement is incorrect
Exhaust 02 Concentration Not Available
When all exhaust constituents, other than 02. are available, the
computation process computes a concentration for 02. This
calculated concentration is that which would be present, assuming the
measured concentrations for all the other exhaust constituents were
exact. When a valid exhaust 02 concentration is not available, the
equation for computation of "A" is as follows:
A = [20.946 -(0.2095 +0.0524*y -0.1047«z)*%HC
- 0.1047«%CO -0.3142»H2FAC] / [%HC+%CO+%C02]
+ 0.0524»y - 0.1047*z - 0.2095*f (13)
Only Exhaust C02 or 02 Available
When only the exhaust C02 cchcentration or the 02 concentration
is available, and the concentrations of other exhaust constituents are
known to be negligible, it is possible to compute a reasonable
estimate of APR. When only the exhaust C02 or 02 is known, and
the other constituents are either unknown or negligible, .the equations
for "A" reduce to the following:
C02 Known:
A * 20.946/%C02 + 0.0524«y - 0.1047*z - 0.2095«f
02 Known:
A - [%02*(4.7742 + 0.9435*y - 1.8871*z + f)]
/ [100. - 4.7742*%02] + 1.0 + 0.25*y - 0.5*z
APR COMPUTATION PROCESS
Computation of APR is outlined as follows:
1. Compute fuel factors using Equations 3,
2. Convert emissions using Equations 4.
3. Compute A using Equation 11,13,14 or 15.
4. When Equation 10 is used, compute 02BAL.
5. Compute SAFR and APR using Equations 2 and 8.
6. If X is desired, compute using Equation 9.

OXIDATION POTENTIAL PROCESS " *" * ': V:
When the APR is very close to stoichiometric (such as with three-
way catalyst systems), the standard APR computation can result in
significant error, relative to the magnitude of the APR, Under such
conditions, a better approach is to utilize an "oxidation potential"
process (OXIPOT). This process is related to the REDOX
computation developed by Gandhi et al (1976), and utilizes the
exhaust constituents that are present in relatively small quantities near
stoichiometric APR (OXIPOT process does not use C02, H20, and
N2). The exhaust APR is stoichiometric, relative to oxidation
potential, when:
t + 0.5n = (l+0.25y-0.5z)c + 0.5m + 0.5h
The components having oxidizing potential are to the left of the
equal sign, and those having reducing potential are on the right of the
equal sign. OXIPOT is defined as the oxidizing potential divided by
the reducing potential:
OXIPOT = (t +0.5n] / [(l+0.25y-0.5z)c +0.5m +0.5h]
Solving OXIPOT in terms of the concentrations of the exhaust
constituents results in (H2FAC from Equation 10):
OXIPOT =
[2.«%02 + %NOX1
[(2.+0.5*y-z)*%HC '+ %CO + H2FAC]
(16)
OTHER CONSIDERATIONS
There are several other considerations, such as wet air-to-fuel ratio
(WAFR), fuel-to-air ratio (FAR and WFAR), and air-to-combustible
fuel ratio (ACFR and WACFR), that can be computed:
Wet Air-to-Fuel Ratio
Calculated dry APR can be converted to a wet air-to-fuel ratio
(WAFR) as follow:
WAFR = AFR*(1 + H/1000) (20)
H = Absolute humidity (grams of water per kg of dry air)
Fuel-to-Air Ratio
Fuel-to-air ratio (FAR) is total fuel divided by dry air (FAR is the
inverse of the APR):
FAR = FUEL/AIR
FAR = 1/AFR
(21)
FAR divided by the stoichiometric FAR (SFAR) is identified as :
= FAR/SPAR
= SAFR/AFR
(22)
It is also possible to calculate lambda (X = AFR/SAFR) using the
oxidation potential. The APR is stoichiometric when the total oxygen
from the intake air is (1 + 0.5*y - z), and the computation for
OXIPOTX is as follows:
OXIPOT X = [(2- * 0.5*y - z) * 02FAC]
[2. + 0.5*y - z]
(17)
02FAC = [2.*%02 +%NOX -(2.-H0.5*y-z)*%HC
-%CO -H2FAC] / [%HC+%CO+%C02]
The values for OXIPOT and OXIPOTX can be used in determining
whether the exhaust composition is oxidizing (has excess 02) or
reducing (deficient in 02) as follows:
'••*>.
OXIPOT or OXIPOTX>1 Exhaust is Oxidizing (18)
OXIPOT or OXIPOTXS1 Exhaust is Reducing (19)

This solution is more complex because the value oft must be expressed in terms of other exhaust constituents, and thus eliminated, before
expressing "A" in terms of measured emission concentrations. The solution is from the basic combustion equation as follows:
Begin with the following from [B], [C], and [E] on the previous page:
A = 0.5zc + 0.5m + d + 0.5n +1 + 0.5w + 0.5z
w = 0.5y-0.5yc-h •
%02 = t*(%HC + %CO + %C02) from t = %02/(%HC + %CO + %C02)
From the basic combustion equation, the percentage of free oxygen in the total dry exhaust is:

INTRODUCTION
The automotive industry has conducted research
regarding the effects of humidity on emissions in
four stroke gasoline and diesel engines (1,2,3).
This body of work has identified the general trends
of emissions with.increasing humidity levels and
investigated the relationships between humidity
and air fuel ratio and in-cylinder heat capacity
change (4,5). As is usually the case, there is little
data examining the humidity effects on large-bore
engines. Additionally, the majority of the
automotive research was conducted before there
was any interest in air toxic emissions and only
considered criteria pollutants.
The American Gas Association (AGA) sponsored a
project in the fall of 1996 to investigate the effects
of varying humidity levels on emissions from a
large-bore engine. The project was conducted at
the Colorado State University Large-Bore Engine
Test-bed (LBET) and included criteria and air toxic
emission data. The project equipment was
specified, installed and the testing completed by
September 1997.
PROJECT OBJECTIVE
The goal was to provide a system capable'of
simulating a 100% relative humidity day at sea
level and 90°F in the LBET for the range of ambient
conditions typically encountered in Fort Collins,
Colorado. Additionally, the capability to control and
vary the humidity level from the minimum possible
(Fort Collins ambient conditions) to 100% RH on a
90°F day at sea level was required. Once the
system was in place, the testing program consisted
of various humidity maps in which the humidity was
the only independent parameter.
TEST SETUP
The humidity control system was designed and
specified by the EECL personnel and consisted of
a variety of commercially available items. The
Woodward Governor Company provided
assistance with the controls and integrated them
into the existing engine controller. The major
components of the humidity control system
included the LBET, water supply system, steam
nullification delivery system, the atomizing
nozzle system, and humidity sensors.
Large-Bore Engine Test-bed
The LBET was commissioned by the gas pipeline
industry in 1992 to provide an independent .
research facility to assist in the development of
emission reduction technologies for large-bore
engines. Due to the generous support of the
industry, the LBET has evolved into a state-of-the-
art facility conducting some of the most advanced
research ever attempted on large-bore engines.
The centerpiece of the test-bed is a highly
instrumented four cylinder, 14 inch bore, 14 inch
stroke, two-cycle natural gas fired Cooper-
Bessemer GMV-4TFS engine. The engine has a
sea-level rating of 440 bhp at 300 rpm. There are
102 engine parameters continuously monitored,
including in-cylinder pressures for real-time
combustion analysis. Load control is accomplished
with a water brake dynomometer and the engine is
outfitted with a turbocharger simulation package
which allows operation at a range of air manifold
pressures to mimic piston scavenged and clean
burn GMV configurations. The engine is equipped
with a Woodward Governor Autobalancer system
to provide precise cylinder peak pressure balance
during testing. The test-bed uses protocol
analyzers as well as a Fourier Transform Infrared
Spectrometer (FTIR) to examine criteria and air
toxic emissions. The addition of the humidity
system compliments the existing systems that
allow control of air manifold temperature and
pressure, fuel manifold temperature and pressure,
and jacket water temperature.
Water Supply System
A reverse osmosis water supply system was
selected to provide the pure water for
humidification of the engine inlet air (Figure 3). A
1500 gallon storage tank was added to reduce the
duty cycle of the reverse osmosis machine.
Steam Humidification Delivery System
A high pressure, natural gas fired boiler was used
to generate steam and deliver it through a control
valve to injection rails placed inside the inlet air
duct of the engine (Figures 1, 2 ,6). The injection
was carried out downstream of the supercharger
(turbocharger simulator) and required the addition
of a mixing section of duct to ensure entrainment of
the water vapor in the air stream (Figure 2). The
steam injection was the primary method of injecting
water vapor. In order to maintain a constant air

Mass/'hr = Mole of Exhaust Gas * hr U B
However, the moles of exhaust gas/hr produced by the combustion ft
source is not known. It is this quantity that can be derived from the fact U
that the fuel and exhaust gas contain the same amount of carbon, as shown
in the next section. |
B. Derivation of an Expression for Moles/Hr of Exhaust Gas
I
An expression for the Moles of Exhaust/Hr can be derived from fuel ^
composition and molecular weight and the measured values of fuel flow and
volumetric concentrations of CO, C0i> and hydrocarbons in the exhaust. £
The expression is: ^
/Mass of Carbo'n in FuelV _J|
Moles of Exhaust _ I hr ' (3) '"""'
hr /Mass of Carbon in ExhaustV w
I Mole of Exhaust J I
Since the total mass of carbon/hr put into the system by the fuel m
must be equal to the total mass of carbon/hr leaving the system in the I
exhaust gas. -•'--. '
Sections 1 and 2 below will derive the expressions for mass of car- w
bon from fuel/hr and mass of carbon from exhaust/mole of exhaust,
respectively. . |i
1. Derivation of Expression for Mass of Carbon from Fuel/Hr
• •• •• it
The problem is to determine the Mass of Carbon/Hr put into the f!
system from the fuel using either an assumed or actual fuel composition
Itf
and the measured fuel flow. II
If the mass (or mass rate) of a gas mixture is known, the mass
(or mass rate) of each constituent can be found as follows: II

poses contains only liquid hudrocarbons
WhUe an analysis of gasoline fuel is not normally available, the
generally accepted hydrogen to carbon ratio for gasoline is 1. 85. This
gives a mass fraction of carbon in gasoline of . 86519.
It should be recognized that the summation term in equation (10)
divided by the fuel molecular weight,, needs only to be multiplied by the
molecular weight of carbon to be an expression for the mass fraction of
carbon in the fuel. Therefore, the expression could be thought of as the
mass fraction of carbon in fuel divided by the molecular weight of carbon.
Substituting the appropriate numerical values in equation (10) gives I
the equation for gasoline. ™

As a further example, the equation for mass emissions of NOX

First, note that the Federal Register defines the term TC:

The constant multipliers 1.8 and 6 come from the fact that the

BSE = the brake specific emissions g/HP-HR
4. NOX Correction for 15% 02

is then corrected to an assumed oxygen level of 15% in the
exhaust.

C. Exhaust Emissions
1 The total carbon method of calculating mass exhaust emission
rates is based on the assumption that all of the carbon in
the exnaust comes from the fuel. The general equation for
mass emissions in terms of Ibs/hr is:
E
Where:
Volume % E X MH of E X Wf X FPCTC
TC X MW of fuel
(13)
E = Mass exhaust emission rate constituent under consid-
eration (i.e. HC, CO, or N0x)
Volume % E = the measured volumetric concentration of E
MW of E = molecular weight of E
= 46.0055 for NOX •
= 12.01 + 1.008 ||~ for HC
» 28.0106 for CO
FPCTC * Fuel percent carbon (equation 12)
TC = Total exhaust carbon (see below)*
FMW a Fuel molecular weight (equation 11)
The measured volumetric concentration of CO is corrected for
the humWat 34°F from the condenser and for the CO,, removed
with the ascarite in the drying column. The equation is:
Volume %
ppm CO
= 100Q X
100
0<678
100 - Volume % Ec02_
x 100 "
Of all of the components present in the intake air, C02 is
assumed to be the only compound present in significant quanti-
ties to affect the exhaust emissions in the carbon balance
calculation. This correction is applied because the_ambient
species are not monitored. The carbon balance equation for
total exhaust carbon is expressed as:
0.33 X 180
*TC » Volume % CO- + Volume % CO + Volume % HC - i80 + volume % CO
2. Fuel Specific Emissions

Example Calculations for Pollutant Mass Flow Rates
Waukesha 3521GL Engine
(shown using data from Run 1)
***NOTE: Calculated results may not agree exactly with spreadsheet results due to rounding.
Part I - Determination of Volumetric Flow.
Volumetric flow rate was calculated by multiplying the heat applied to the engine by an oxygen-based
combustion products (Fd) factor:
Heat Applied to engine:
Heat Rate (MMBtu/hr) = [Fuel Flow Rate (scfh) * Higher Heating Value (Btu/cf)] /106 Btu/MMBtu
Heat Rate (MMBtu/hr) = [5418 scfh * 1135.1 Btu/cf] /106
Heat Rate = 6.15 MMBtu/hr
Volumetric Flow Rate
Volumetric Flow Rate (dscfm) = Fd (dscf/MMBtu) * Heat Rate (MMBtu/hr) * [20.9/(20.9-02)] / 60 min/hr
Volumetric Flow Rate (dscfm) = 8654 dscf/MMBtu * 6.15 MMBtu/hr * [20.9/(20.9-9.8)] / 60 min/hr
Volumetric Flow Rate (dscfm) = 1670 dcsfm
Part II - Determination of Pollutant Mass Flow.
The concentration of the target pollutant was converted to units of Ib/cf, and multiplied by the calculated
volumetric flow rate to obtain a mass flow rate. The example shows the calculation of mass flow rate of
carbon monoxide (CO) at the pre-catalyst location.
Mass Flow Rate - Ib/hr
ECO (Ib/hr) = Ceo (ppmvd) * (MWCO / 385.3 x 106 )* Volumetric Flow Rate (dscfm) * 60 min/hr
ECO (Ib/hr) = 620 ppmvd * (28 / 385.3 x 106) * 1670 dscfm * 60 min/hr
ECO =4.51 Ib/hr
Mass Flow Rate - g/bhp-hr
ECO (g/bhp-hr) = Eco (Ib/hr) * 453.6 (g/lb) / Engine Load (bhp)
ECO (g/bhp-hr) = 4.51 Ib/hr * 453.6 g/lb / 737.29 bhp
ECO = 2.77 g/bhp-hr
ExampleCalcs.doc
-------
Part III - Determination of Catalyst Removal Efficiency.
Catalyst removal efficiency was determined by subtracting the mass flow rate at the outlet from the mass
flow rate at the inlet, then dividing by the mass flow rate at the inlet.
Catalyst Destruction Efficiency
%DE »[Eco Inlet (g/bhp-hr) - Eco Outlet (g/bhp-hr)] / Eco Inlet (g/bhp-hr) * 100
%DE = (4.51 g/bhp-hr-0.301 g/bhp-hr)/4.51 g/bhp-hr*100
DE = 93,3%

Energy Lab Memo, •
To: Mr. Terry Harrison, U.S. Environmental Protection Agency
Mr. Michael Maret, Pacific Environmental Services, Inc.
From: Dr. Bryan Willson
Research Director, Engines & Energy Conversion Laboratory
Date: July 13,2001
Subject: Modifications to Report on 4-Stroke Lean Burn Engine (Waukesha)
The following modifications / errata apply to the "Four-Stroke, Lean-Burn, Natural Gas Fired
Internal Combustion Engine" report (i.e. the "Waukesha Report") submitted to PES in April,
2000.
2 "Waukesha stated that certain values in Table 2.2 of the draft report appeared to be
incorrect, specifically the value for oxygen at the catalyst inlet for Run Nos. 3 and 13."
This was discussed in Section 3.4 of the CSU report. As noted in Section 3.4, the pre-
catalyst oxygen data for Run #3 is incorrect. The paramagnetic oxygen analyzer failed
during the test. As noted in Section 3.4, the air/fuel ratio is 28:1 for the oxygen value of
9.81% measured at the catalyst outlet.
The pre-catalyst oxygen value of 10.44% measured during Run No. 13 is higher than the
9.81% value measured at the catalyst outlet. The pre-catalyst value is suspect, but as the
analyzer passed a QC check, a pre-test calibration check, and and a post-test calibration
check, CSU has no justification to "invalidate" the oxygen reading.
15 "This comment states that the air/fuel ratios shown in the baseline run on August 5 are in
error, and that the correct air/fuel ratio should be closer to 28.6."
Due to a failure with the oxygen analyzer, the air/ruel ratio is incorrect. Using an air/ruel
ratio of 9.9%, the value at the catalyst outlet, the air/ruel ratio is calculated at 28.6.
18 "This comment notes that the units of barometric pressure reported in the CSU reports are
in inches of mercury, but the values appear to be in psia."
The comment is correct. The units of barometric pressure should be modified to read
"psia"
19 "Waukesha noted that the tabulated "Air Manifold" temperatures are always about 99.5
°F, and noted that this does not make sense."
The "Air Manifold" temperature is actually the temperature of the air in the air supply
manifold to the engine, and not on the engine itself. The air supply temperature is
maintained at this value by a closed-loop control system.
20 "Waukesha noted that the values for the "Average Cylinder Exhaust Temperature" are
always in the low to mid 700 °F range, and that this value is too low."
A thermocouple was added at an intermediate point in the exhaust between the pre-catalyst
-------
g
Annubar™ flow meter and the catalyst. The parameter was mis-labeled on the engine test
runsummary, * it
21 "Waukesha commented that a value for "In-cylinder Temperature " was also given and that II
this value was typically 25 - 35 °F. " ^
This measurement is made during testing of other types of engines at the EECL. It was not II
used during testing of the Waukesha. Its inclusion on the datasheet was in error.
22 "This comment notes that the removal efficiencies for formaldehyde were presented in II
decimal format instead of per cent format. " **
The comment is correct. The efficiency values are listed in decimal format, and not in ||
percent format as indicated in Appendix A. II
24 "Waukesha noted that the inlet air humidity in CSU's Table 3 is incorrect. "
The comment is correct. The inlet air humidity baseline should written as ".015 Ib H20/lb i|
Air", not the ".0015 Ib H20/lb Air" listed in Table 3.

Reference: Draft Final Report; Waukesha F3521GL Engine Test
Dear Mr. Harrison,
Thank you for sending me a copy of the draft final report on the HAPs testing of a 4-
stroke, lean burn, gas-fired, reciprocating internal combustion engine (the Waukesha F3521GL)
at Colorado State University (CSU) to review. I have been able to review the main Pacific
Environmental Services (PES) text and the text and Appendices A and B of the CSU report (part
of Appendix A of the PES document).' I will provide most of my comments in this letter.
However, as you suggested, I am also attaching copies of pages from the report with notations
made in the margins. In no specific order I offer the following comments and suggestions for
your consideration:
> To answer your first question, the engine appears to be operating normally during all
of the 16 data runs. To further verify engine operation I compared the performance
summary in Table 2.2 with our published performance at two load points, data runs
#1 and #3. Our published data are reference Waukesha document S-06124-62.
Run#l: 1200 rpm, rated 738 bhp
Table 2.2 S-06124-62
Fuel consumption 7468 Btu/bhp-hr 7377 Btu/bhp-hr '
Exhaust temperature 735° F 703° F
Exhaust gas flow 1660dscfm 1616dscfm
Run #3: 1000 rpm, 432 bhp
Table 2.2 S-Q6124-62
Fuel consumption 7718 Btu/bhp-hr 7528 Btu/bhp-hr
Exhaust temperature 677° F 666° F
Exhaust gas flow 914dscfm 966dscfm
These values-agree within a normally expected tolerance.

> Having said that, there are certain values in Table 2.2 (and, of course, the CSU
Appendix A values from which they were obtained) that appear to be incorrect. ^
These incorrect values can result in subsequent erroneous calculated values. II
Specifically, the catalyst inlet oxygen values appear to be in error - too high - for
runs #3 and #13. In both cases the value should be closely 9.8%. Run #3 in the CSU n
Appendix A data actually indicates 1 00.0% oxygen. This was, apparently, interpreted Jj,
by PES as being 1 0.0%. The catalyst outlet oxygen values are correct. You can
confirm these errors by comparing the catalyst inlet and outlet values. The normal ft
difference is measured in hundredths of a percentage point. In addition, the oxygen ||
value for these runs was to have been set to 9.8%, the standard value. In run #1 3 this
oxygen error is seen to noticeably affect the calculated catalyst inlet gas flow value.
The 1703 dscfrn value is too high.
u
> In general, the criteria emittant (NOx, CO, and THC) values agree with Waukesha jl
experience. However, the NOx values are a bit lower and the total hydrocarbon II
values a bit higher than expected. This would be consistent with the engine running
slightly leaner than our standard setting. It
> The non-methane hydrocarbon values are about twice Waukesha's normal value.
This is directly due to the fuel gas composition at CSU having about twice the ethane II
and heavier components than our normal, Midwestern natural gas. "
> The formaldehyde levels presented in the report are higher than those measured at D
Waukesha on a similar engine. "
> It should be noted in the report - and considered by the EPA during the HAPs MACT II
rulemaking - that NOx universally increased across the oxidizing catalyst. ™
Reference Table 2.3 values. The average increase was just over 8%. I assume that . ,
the NOx values given for both the catalyst inlet and outlet are on the same basis, i.e., 11
as N02 per EPA convention. This characteristic will result in increased difficulty for
lean burn engine sources fitted with an oxidizing catalyst to comply with existing *.
NOx standards, some of which are now at very stringent levels. II
> I understand that the methane / non-methane values and the total hydrocarbons values m
were measured with different instrumentation (reference Table 5.1 and Figure 5.1). jl
There is a noticeable discrepancy between the two measurements. Table 2.3 shows
both methane and non-methane hydrocarbons decreasing across the catalyst (with one 11
exception that likely represents erroneous values). The total hydrocarbon values, ||
however, increase across the catalyst for 12 of the 16 runs. Of the other four runs,
one showed no change and the remaining three showed very minimal decrease. There fee
may be little change in methane across the catalyst due to methane's high "light off' J|
temperature, but, in our experience, non-methanes and, therefore, total hydrocarbons
should decrease across an oxidizing catalyst. ' jj

-------
> The non-methane hydrocarbon value at the catalyst outlet in run #8 appears to be in.
•. error in Table 2.3. It shows a very unusual large increase over the inlet value. See
also Table 2.4.
> The total hydrocarbon instrumentation is not described in the text in section 5.
> Why are the NOx and methane (catalyst inlet) and NOx (catalyst outlet) values given
to only one place after the decimal (tenths) for runs 10 -16 in Table 2.3? The
reduced precision of these values versus the other nine runs makes accurate
comparisons difficult.
> Comparing runs #1, #2, and #5 with runs #4, #3, and #8, respectively, (speed
reduction at constant loading) I note that the brake specific NOx decreased with the
decrease in speed. Waukesha's experience indicates the opposite response. Typically
- with all other factors constant - reducing speed leads to an increase in brake
specific NOx rate.
> Runs #15 and #16 do not appear to give any significant information. Here, engine
unbalance / misadjustment was simulated by retarding / advancing the spark timing of
one cylinder relative to the remaining five. At most, these changes would be
expected to yield 17% (1/6) of the changes seen in runs #13 and #14 where the timing
of all six cylinders was changed. The results seem to indicate that the changes in
engine performance were masked, i.e., were less than normal run-to-run variation.
> Table 2.3 in the report gives different emission rate values across the board for all
specie - criteria and HAPs - than those in the Colorado State tabulation in CSU
Appendix A. I assume that the g/bhp-hr and Ib/hr values were recalculated from the
raw data by PES using a different methodology resulting in the different values.
However, since this apparent discrepancy can result in confusion to anyone reading
the report, this situation should be specifically addressed and explained in the report.
Comments specifically regarding the CSU data presented in CSU Appendix A:
> In general, all of the CSU air / fuel ratio values in CSU Appendix A seem a bit high -
typically running above 28.5:1. With the fuel used at CSU and the standard 9.8%
oxygen nominal carburetor setting I would expect values about 1 APR lower, i.e.,
about 27.5:1 nominal.
> The air / fuel ratio values given in the August 5 baseline in CSU Appendix B are in
error. Instead of the indicated 32.70 figure, the "correct" value should be closer to the
28.6 figure shown in the August 6 baseline.
> CSU Appendix B does not include the 1000 rpm baseline run that was also taken on
August 6.
-------
II
., . . , , II
> As noted earlier, CSU Appendix A, run #3 shows pre-catalyst oxygen as 100% and
A/F ratio (wet) as 31.5. Both are obviously wrong. The oxygen level should be ||
about 9.8% and the A/F ratio about 28.8:1. The 100% oxygen level appears to have j|
resulted in all the F-factor Emissions Calculations (down to acetaldehyde) being
listed as negative and significantly reduced in absolute value. ll
> The barometric pressure values in CSU Appendix A are listed as inches of mercury
while the numerical values appear to be psia. If not noticed and corrected, this could ll
affect calculated values. . II
> The tabulated "Air Manifold" temperatures are always about 99.5° F. This does not II
make sense unless the air manifold referred to is not the air manifold on the engine II
but, rather, a duct bringing air to the turbocharger. The engine mounted air manifold
(intake manifold) temperature should be about that of the intercooler air out. II
> The "Average Cylinder Exhaust Temperature" is always in the low to mid 700° F -,
range. This is too low. It should have about the same value as the average given in II
the exhaust temperature block of data, i.e., in the mid 900° F range typically. The
lower temperature is more compatible with an exhaust stack temperature post- H
turbocharger. An "Exhaust Header Temperature" in the mid-7000 F range is also j|
listed. This temperature must also be at a location downstream of the turbocharger.
> An "In-Cylinder Temperature" (just above the F-Factor Emissions values) is also ||
given. This value is typically 25° - 35° F and is nowhere near an engine in-cylinder
temperature. ji
> The CSU tabulated catalyst conversion efficiencies for formaldehyde are given in a
decimal format, not the percent value as indicated. II
> As previously mentioned, the 10.44% value for pre-catalyst oxygen given for run #13
is incorrect. It should be about 9.8%. The air/fuel ratio listed is compatible with a II
9.8% oxygen level. II
II
Text and typographical comments: . W
> The inlet air humidity level in CSU Table 3 is incorrect. It should be .015 Ib H20 / Ib ll
air. II
> PES report, page 3-1, §3.1, first paragraph. "Air is delivered to the engine via a ll
supercharged air delivery system...". This is confusing since the F3521GL engine is, ™
itself, turbocharged but superchargers are used on smaller engines. If this sentence is ^
referring to a facility air delivery system I suggest use of an alternative word, e.g., ll
"pressurized", to eliminate confusion. If this sentence does, in fact, refer to the
engine's air delivery system the text should be corrected to read "... turbocharged air u
delivery system...". II
-------
> PES report, page 3-1, §3.1, second paragraph. "During the expansion stroke ...".
This is incorrect and should read "During the intake stroke...". In the context of a 4-
stroke cycle engine, the expansion stroke is identical to - and is an alternative term
for-the power stroke.
> PES report, page 3-4, §3.2, first paragraph (and other places). The correct units of
torque are pound-feet or Ib-ft (force x distance). This is entirely analogous to the SI
system of units where torque is specified in Newton-meters or N-m.
> PES report, page 3-4, §3.2, first paragraph. "... engine timing (the location of the
cylinder, relative to top dead center, at the time of peak pressure in the combustion
chamber, measured in degrees)...". This is incorrect in several respects. It should
properly read "... engine timing (the location of the piston, relative to its top dead
center, at the time the spark plug fires in the ^combustion chamber, measured in
degrees)...".

3.0 SOURCE DESCRIPTION AND OPERATION
This section presents discussions of the candidate engine and the catalyst used for the test
program. The sections that follow describe the engine and the operation of the engine during
testing.
3.1 ENGINE DESCRIPTION
The Waukesha 3521GL is a 4-stime stationary internal combustion engine. The engine
has six inline cylinders; the total piston displacement is 3520 cubic inches. Each cylinder is
9.375 inches in diameter, and h^oi _8.5-inch stroke. The compression ratio is 10.5:1. Airis
delivered to the engine via a^uparchar'ged^air delivery system; air manifold pressures are
controlled by the EECL process control system. Engine loading is controlled by a computer-
controlled water brake dynamometer. Before the test program EECL installed an oxidation
catalyst, manufactured by MiraTech Corporation, on the engine. EECL aged the catalyst under
its normal operating condition' (i.e., burned in the catalyst) before the test program. This
procedure ensured that the catalyst's HAP destruction efficiency approximated the HAP
destruction efficiency of mature catalysts installed on 4-stroke engines in industry. Table 3.1
presents specifications of the engine and the catalyst. Table 3.2 presents nominal engine
operating parameters. l ,-k;|C^
The 4-stroke cycj^equires two revolutions of the engine crankshaft for each power
stroke. During thd^^a^tutroke, the piston moves down the cylinder and an air/fuel mixture
is injected into the piston chamber. On the compression stroke, the piston moves back up the
chamber, and the mixture is compressed and ignited. The expanding gas generated upon
combustion forces the piston back down the chamber. This stroke is the power stroke. The last
stroke of the 4-stroke cycle is the exhaust stroke. The piston travels back up the chamber and the
combustion products are vented through the exhaust manifold.
The 352 1GL engine was outfitted with lean-burn technology, which controls NOX
emissions. The lean-burn system uses pre-combustion chambers to ignite a lean air/fuel mixture
in the main combustion chambers. A rich mixture of air and fuel is drawn into the pre-
combustion chamber and is ignited by a spark plug. The resulting flame is then directed into the
main combustion chamber, which contains a lean mixture of air and fuel. The flame jet from the
pre-combustion chamber ignites the air/fuel mixture in the main chamber.
Draft Final Report Waukesha 3521GL .3-1 . August 2000
-------
3,2 ENGINE OPERATION DURING TESTING
As stated in Section 2 of this document, three types of test runs were conducted during
the test program: quality assurance runs, sampling runs for FTIRS and CEMS, and baseline runs.
The operation of the engine during these various runs is discussed in the following pages and
tables. The four-stroke engine test matrix described in the QAPP was based upon estimated
operating parameters for a candidate engine to be installed and operated at the EECL. When the
engine was received and first operated by EECL the actual operating parameters differed from
the estimates. Table 3.3 presents the test matrix for the Waukesha engine based upon the actual
engine parameters. During the test program, the six engine operating parameters expected to
have the greatest impact on pollutant formation were varied from their baseline values. These
parameters were: engine speed (measured in revolutions per minute or rpm), engine torque
^\ «—(rneasurettln foot-pounds or ft4b), air-to-fuel ratio (calculated as an equivalence factor^engine
' timing (the locationofflje^^^ relative to top dead center, at the time or^fc^ossure in the p/<
Combuj^en-tMnte^easuWm degrees), air manifold temperature (measured uyaegrees
^ v x 'Ftenheit), and jacket water outlet temperature (measured in degrees Fahrenheit).^poJtil^
Table 3,4 presents engine parameters recorded during each test run and their percent
deviation from the target values.- Sixteen sampling runs were conducted on the engine during the
two-day period. Except for air/foel ratios, the actual parameters agreed with the target
parameters to within 5%. Although the calculated air/fuel ratios were not within 5% of the target
air/fuel ratios, testing was conducted while operating at rich air/fuel ratios (Runs 5 and 8) and at
lean air/M ratios (Runs 6 & 7). The air/foel ratio was varied to simulate the range of air/fuel
ratios that typcial in field applications.
Before starting Run 7, the humidity control system failed. The humidity system could not
be repaired quickly so the run was conducted without inlet air humidity control. Run 2 was also
conducted without inlet air humidity control. The set point for the humidity ratio for all test
points was 0.015 Ib. water / Ib. air. The actual humidity ratios for Runs 2 and 7 were 0.0126 and
0.0127 Ib. water / Ib. air respectively. The engine emissions for Runs 2 and 7 should be similar
to engine emissions at the specified humidity ratio. The most dramatic effect will be on NOX
emissions as can be seen from the data and the graphs presented in Appendix S of the CSU test
report. At a constant humidity ratio, it would be expected that formaldehyde emissions would
either remain constant or increase slightly with similar changes in CO and THC emissions.

SUBJECT: Comments on the EPA Draft Report on the Emission Test Results for the II
Waukesha at the Colorado State University Engines and Energy ™
Conversion Laboratory
Dear Terry: "
Thank you for the opportunity to review the EPA draft report, "Testing of a 4-Stroke II
Lean Bum Gas-Fired Reciprocating Internal Combustion Engine to Determine the
Effectiveness of an Oxidation Catalyst System For Reduction of Hazardous Air Pollutant »
Emissions," dated August 2000. For your information, in April 2000, the Gas Research II
Institute (GRI) and the Institute of Gas Technology (IGT) combined to form GTI, Gas
Technology Institute. This letter provides the comments from GTI and PRC
International.
0
If you have questions regarding the comments provided, please contact me at your
convenience.
Sincerely,
Our specific comments are attached. In general we were pleased to see that the draft n
report for the 4-Stroke Lean Burn (4SLB) engine used a format and approach similar to j|
the final report for the 2-Stroke Lean Burn (2SLB) engine, which incorporated a number
of the comments we had submitted on the draft 2SLB report. Thank you for providing a 11
copy of the comments submitted by Bob Stachowicz of Waukesha. Bob made a number ||
of good points and we have noted our agreement with several of his comments.

GTI and PRC International Comments on the EPA Draft Report
1. As noted above, Bob Stachowicz of Waukesha submitted a number of constructive
comments in his September 1,2000 letter to Terry Harrison of EPA. We particularly
note our support of the following issues raised by Bob:
a) The formaldehyde levels presented in the report are higher than levels measured
in field tests on 4SLB engines. For example, for natural gas transmission
facilities, field testing shows formaldehyde emissions at 0.23 g/bhp-hr for 4SLB
engines running in a low-NOx configuration (see Topical Report GRI-96/0009.1,
"Measurement of Air Toxic Emissions from Natural Gas-Fired Internal
Combustion Engines at Natural Gas Transmission and Storage Facilities"),
whereas the formaldehyde levels in the draft 4SLB report range from 0.28 to 0.35
g/bhp-hr.
b) NOx does increase across the catalyst and that fact raises issues about the ability
of 4SLB engines with oxidation catalysts to comply with NOx requirements. The
error bounds of the data may also contribute to the apparent increase in NOx
across the catalyst and this issue should be investigated further.
c) The 4SLB report should include a more detailed explanation of the total
hydrocarbon, non-methane hydrocarbons, and methane results, including a
discussion of the uncertainties related to the data. In addition, the report should
consider the reactions that may occur across the catalyst, such as the partial
oxidation of methane or other hydrocarbons, that would impact the measured total
hydrocarbons, non-methane hydrocarbons, or methane reduction efficiencies.
Finally, given the uncertainties related to the total hydrocarbon and non-methane
hydrocarbon data, percent reduction efficiencies for those compounds should not
be presented in the report. We also submitted this comment on the draft 2SLB
report.
d) The 4SLB report should include the equations used to calculate the Ib/hr and .
g/bhp-hr emission levels from the ppm values. As Bob noted, the values do not
agree with the values presented in the data report provided by CSU (and included
in Appendix A).
e) The 100% oxygen reading reported pre-catalyst for Run 3 clearly is in error and
the value affected the g/bhp-hr and Ib/hr emission rates reported in the CSU report
~ the values are negative. As Bob noted, PES apparently interpreted this value as
10.0%. PES will need to correct the g/bhp-hr and Ib/hr values for Run 3 once the
correct oxygen reading is available from CSU.
2. Comments related to detection limits:
a) The detection limits for all compounds should be included in the body of the
report. We understand that EPA is awaiting information from Colorado State
University regarding the detection limits, by run, for the FTIR measurements.
The detection limits should be included in the final 4SLB report.
b) In Section 2.4, the report notes that removal efficiencies were not included for
acetaldehyde based on the in-stack detection limit downstream of the catalyst
-------
Mr. Terry Harrison *"
September 20,2000
Page 3 ' "~ II
since the.FTIR detection limits were not available for the draft report. This ^
statement must be in error since acetaldehyde was not.detected for any test If
condition before or after the catalyst. The statement may refer to acrolein, which
was detected before the catalyst in 6 of 16 test conditions, and was not detected ..
after the catalyst for any test condition. II
As we noted in our September 8,1999 comments on the draft 2SLB report, n
destruction efficiency calculations based on the detection limit of a method are ||
misleading. The report should not include emission reduction efficiencies when.a
pollutant is not detected pre- or post-catalyst. If EPA intends to present emission n
reduction efficiencies when pollutants are not detected, appropriate consideration ||
should be given to the error band associated with data measured at or near the
detection limit. Such consideration would result in a range of efficiencies based II
on the range of both catalyst inlet and outlet concentrations. II
3. Section 6.3 includes a discussion of EPA's Data Quality Objective for the 4SLB
emissions test. This discussion states that EPA intended to use the 4SLB emissions II
test to evaluate the effects of combustion modifications as well as the effectiveness of
oxidation catalysts. As we have noted previously, the operating conditions used to
conduct the 4SLB emissions test were selected to simulate operating conditions that II
may be encountered in the normal field operation of natural gas-fired engines. The
operating conditions tested are not sufficient to allow EPA to evaluate the effect of .|
combustion modifications on HAP emissions. Also, engines in variable load ||
applications, such as natural gas transmission, must have the flexibility to operate at a
variety of conditions. Note that the final 2SLB report includes a similar discussion. «
4, On page 5-1, the 4SLB report indicates that FTIR is classified as a Type II method II
and states: "Type II methods were those that used permanently installed instruments
housed in a temperature-controlled environment and operated in the same fashion as II
continuous monitors used by industry to show compliance with emission regulations. II
Because these instruments are maintained in a laboratory-type environment (the
control room at EECL), fewer QA activities and calibrations adequately show their II
continuing accuracy." As we noted in our comments on the draft 2SLB report, the U
second half of the first sentence is not true for FTIR, since there are no instances
where FTIR is used for 1C engines as a continuous monitor to show compliance with II
emission regulations. Also, the characterization of FTIR as a continuous compliance **
monitoring method is not relevant to the point being made that less QA activities and
calibrations were necessary for Type II methods. The second half of the first sentence II
should be deleted, so that it reads "Type II methods were those that used permanently
installed instruments housed in a temperature-controlled environment. Because these
instruments are maintained in a laboratory-type environment (the control room at ||
EECL), fewer QA activities and calibrations adequately show their continuing
accuracy." ' H

MEMORANDUM
July 6,2001
To: Terry Harrison, US EPA
Bryan Willson, CSU EECL
From: Mike Maret, PES
Re: Response to comments received on the Waukesha Draft Final Report
This memorandum summarizes the telephone conference between Terry Harrison (EPA
EMC), Bryan Willson (CSU EECL), and Mike Maret (PES) that took place on June 11,2001.
The purpose of the telephone conference was to 1) discuss comments that were received by EPA
on the draft final report for the Waukesha 3521 reciprocating engine, 2) to decide which
comments would necessitate revisions when preparing the final report, and 3) the form of the
revisions in the final report.
The call began at approximately 11:10 a.m. EDT. EPA received two sets of comments
pertaining to the Waukesha draft final report. The first set of comments that was discussed were
those received from Mr. Bob Stachowicz of Waukesha. Mr. Stachowicz's comments were not
numbered; the group numbered the comments during the phone call. EPA's response to each
comment is summarized below.
1. The first comment compared engine operational data developed by CSU for Runs 1 and 3
with historical Waukesha engine data. Waukesha stated that the values developed by
CSU were within normally expected tolerances.
EPA decided that since the comment does not identify an error or omission, no change to
the report is required.
2. Waukesha stated that certain values in Table 2.2 of the draft report appeared to be
incorrect, specifically the value for oxygen at the catalyst inlet for Run Nos. 3 and 13.
CSU stated that the oxygen data for Run No. 3 was invalid. Together CSU, EPA and
PES developed a strategy to correct invalid data. When invalid oxygen data is detected, the
oxygen data for the 5-minute Quality Control run will be substituted and used for subsequent
calculations. If the QC data is also determined to be invalid, oxygen data from the catalyst outlet

will be substituted and used for subsequent calculations. Since for Run No. 3 the oxygen data "
was invalid EPA directed CSU to recalculate inlet values using the outlet concentration of outlet
oxygen value of 9.8%, II
CSU recognized that the measured oxygen value of 10.4% during Run No. 13 appeared to „
be higher that normal. An examination of the raw data did not turn up any reason to invalidate ||
the data, EPA directed PES to use the oxygen value supplied by CSU, but to footnote the value
as being suspect. n
3, This comment discussed observed criteria emittant (NOX, CO, and THC) values. n
EPA decided that since the comment does not identify an error or omission, no change to
the report is required. • II
4. This comment discussed observed non-methane hydrocarbon (NMHC) values. ||
EPA decided that since the comment does not identify an error or omission, no change to
the report is required. 11
5, This comment discussed observed formaldehyde values. ||
EPA decided that since the comment does not identify an error or omission, no change to _«
the report is required. ||
6, This comment requested that it be noted in the final report that NOX universally increased ||
across the oxidizing catalyst.
EPA decided that since the comment does not identify an error or omission, no change to [|
the report is required..
0
7. This comment discussed methane and NMHC data, the fact that these measurements were
made with different make and models of analyzers, and perceived discrepancies in the II
measurements over the 16-run test program. "
EPA directed PES not to make any corrections to any data, but to note in a footnote that IK
different models of analyzers were used to measure these values. ™

-------
8. Waukesha noted that the NMHC value at the catalyst outlet during Run No. 8 is very high
compared to the inlet and appears to be in error,
EPA, PES, and CSU examined the NMHC concentration data for Run No. 8. The
reported pre-catalyst concentration was 171 ppm. The reported post-catalyst concentration was
284 ppm. The NMHC concentration data for the QC run conducted just prior to Run No. 8 was
examined. The NMHC concentrations were 168 ppm and 155 ppm at the pre- and post-catalyst
locations, respectively. CSU and PES proposed that NMHC mass flow rates and NMHC
destruction efficiency be calculated using the data from the QC run, and that the data from the
test run be invalidated. EPA agreed with this approach. These values will be footnoted in the
revised table.
9. This comment states that the a description of the total hydrocarbon instrumentation used
was not included in the report.
EPA directed PES to include a description of the instrumentation used.
10. This comment states that NOX and methane values at the catalyst inlet and NOX values at
the catalyst outlet were only reported to only one place after the decimal for runs 10-16
in Table 2.3.
Upon inspection of the table PES noted an error in the number of significant figures that
were reported. EPA directed PES to correct the error in the final report.
11. This comment notes that brake specific NOX emissions during the testing program

EPA decided that since the comment does not identify an error or omission, no change to
the report is required.

emission rates reported by CSU in Appendix A. II
PES used EPA Method 19 to calculate pollutant mass flow rates at the catalyst inlet and ||
catalyst outlet locations, as specified in the Quality Assurance Project Plan (QAPP). The gas U
volumetric flow rate at each location was calculated using the fuel factor and flue flow rates
supplied by CSU. The mass flow rate for each target compound was calculated using the I
concentration values reported by CSU, and the calculated volumetric flow rates. PES could not u
reproduce CSU's calculated values when preparing the draft final report. EPA directed PES to
prepare a set of example calculations that were used, and to forward these calculations to CSU II
and EPA for further review.
The following comments were made specifically regarding the CSU data presented in the CSU
report, which was included as Appendix A in the draft final report. n
14. Waukesha stated that all of the air/fuel ratios reported by CSU seemed a bit to high n
compared to Waukesha's expected values. II
EPA decided that since the comment does not identify an error or omission, no change to ||
the report is required. •
15. This comment states that the air/fuel ratios shown during the baseline run on August 5 are «
in error, and that the correct air/fuel ratio should be closer to 28.6.
CSU examined the oxygen data presented in the baseline run. The catalyst inlet oxygen »
monitor failed during mis run, therefore the calculated air/fuel ratio is in error. This error was
described on Page 3-4 of the CSU report. CSU will recalculate the air/fuel ratio using the oxygen ||
value of 9.8% at the catalyst outlet.

16. This comment notes that CSU's Appendix B does not include data for the 1000 rpm
baseline run that was taken on August 6. n
The 1000 rpm is an invalid baseline data point. Baseline testing was conducted at an
engine speed of 1200 rpm. A1200 rpm baseline run was conducted on August 5 and 6. EPA n
directed PES to remove the 1000 rpm baseline run from the final report. 1
17. Waukesha commented that the pre-catalyst oxygen value observed during testing (100%) 1
is obviously wrong.

18. This comments notes that the units of barometric pressure reported in the CSU report are
in inches of mercury, but the values appear to be in psia.
CSU confirmed that the values are hi psia. CSU will generate an errata sheet noting this
error. PES will include this error in the final report. Further, PES will make a hand notation on
the CSU run data in Appendix A of the CSU report.
19. Waukesha noted that the tabulated "Air Manifold" temperatures are always about 99.5 °F,
and noted that this does not make sense.
CSU explained that the "Air Manifold" temperature is the temperature of the air supplied
to the engine by the EECL's combustion air blower. CSU will add this mis-labeled parameter to
the errata sheet. PES will make a hand notation in the CSU run data.
20. Waukesha noted that the values for the "Average Cylinder Exhaust Temperature" are
always in the low to mid 700 °F range, and that this value is too low.
CSU explained that a thermocouple was added at an intermediate point in the exhaust
between the pre-catalyst annubar flow meter arid the catalyst. The parameter was mis-labeled on
the engine test run summary. CSU will add this error to the errata sheet. PES will make a hand
notation in the CSU run data.
21. Waukesha commented that a value for "In-cylinder Temperature" was also given and that
this value was typically 25 - 35 °F.
CSU stated that this value is an erroneous value for the Waukesha engine set-up. This
value is sometimes used during testing of other engines at the facility. CSU will add this error to
the errata sheet. PES will make a hand notation in the CSU run data.
22. This comment notes that the removal efficiencies for formaldehyde were presented in
decimal format instead of percent format.
CSU will add this error to the errata sheet. PES will make a hand notation in the CSU
run data.

higher than levels measured in field tests on 4SLB engines.
EPA decided that since the comment does not identity an error or omission, no change to
the report is required.
Ib. GRI reiterated the fact that NOX emissions increased across the catalyst, and stated that
this phenomenon would raise issues about the ability of 4SLB engines with oxidation
catalysts to comply with NOX requirements.
EPA decided that since the comment does not identify an error or omission, no change to
the report is required.
Ic. GRI requested that the final report include a more detailed explanation of the total
hydrocarbon, non-methane hydrocarbon and methane results, and that chemical reactions
across the catalyst (such as partial oxidation reactions) should be considered. The
comment also stated that destruction efficiencies for these compounds not be included in
the final report.

16. ABSTRACT
The United States Environmental Protection Agency (EPA) is investigating Reciprocating Internal Combustion Engines (RICE) to characterize
engine emissions and catalyst control efficiencies of hazardous air pollutants (H APs). This document describes the results of emissions testing
conducted on a Waukesha 3521GL natural-gas-fired, 4-stroke, lean bum (4SLB) engine. Early in 1998, several industry and EPArepresentatives
agreed that the Waukesha 3521GL engine at the Colorado State University's (CSU) Engine and Energy Conversion Laboratory (EECL) is adequately
representative of existing and new natural-gas-fired 4SLB engines. The group agreed that a matrix of test results from testing conducted at the EECL
could be used to develop Maximum Achievable Control Technology (MACT) standards for RICE. The group further agreed that an oxidation catalyst
installed on the Waukesha 3521GL could be used to determine the effectiveness of oxidation catalysts forthese engines, and that the EPA could use the
results from testing at the 4SLB matrix conditions at CSU as the basis for developingthe MACT standard for natural-gas-fired 4SLB engines.
The testing was performed to estimate HAP emissions before and after the oxidation catalyst Miratech Corporation manufactured the catalyst and
CSU personnel installed it on the engine. Fourier transform infrared spectroscopy (FTIRS), owned and operated by CSU, was used to measure
formaldehyde, acetaldehyde, and acrolein. Continuous emission monitors (CEMs), owned and operated by CSU, were used to measure oxygen (Oj),
carbon dioxide (C02), nitrogen oxides (NO,), carbon monoxide (CO), total hydrocarbons (THC), methane (CIL,), and non-methane hydrocarbons
(NMHC).
This document is comprised of 427 pages and consists of the report text, and Appendices A and B.
