ABSTRACT
Research was done to assess the long term durability of closed-loop three-way
catalyst technology in nonroad large spark-ignited (LSI) engine applications. Two LPG-
fueled forklift trucks with three-way catalyst systems having accumulated more than 4,000
hours use were selected. Recorded in-field operation parameters were used to generate
a new transient cycle. The engines and the emission control systems from the two forklift
trucks were tested for emission performance under several steady-state conditions, and
over five different transient test cycles. Performance deterioration trends were established
through the use of both new and aged emission control system components. Failed
catalytic converter mufflers discovered at the end-user site were investigated for failure
mode. A brief fuel sensitivity study with an "off spec" LPG composition was also
conducted. Finally, a test was performed to measure fuel temperatures in the bulk liquid
volume of the tank of a gasoline forklift truck in near-continuous operation.

Composite emission results for the ISO C2 and D2 steady state tests on the aged
systems were well within the limits of CARB's adopted LSI emission standards. Transient
operation emissions for all the five transient cycles were below the worst case of 14 g/hp-hr
CO, and 2.8 g/hp-hr THC+NOX.

EXECUTIVE SUMMARY
Background - In order to meet ambient air standards in California by the year 2010,
the California Air Resources Board finalized in October of 1998 emission standards for
nonroad spark-ignition engines rated over 19 kW (large SI engines). At that time, there
was limited information on the durability of emission control systems in industrial
applications, and on the ability of manufacturers to control emissions at operating modes
not represented by the steady-state test cycle. Furthermore, there was little information
available to describe typical engine operation, especially with respect to the degree of
transient operation. It was also desired to study the effects of varying LPG fuel quality on
emissions. Since the U.S. Environmental Protection Agency had also started the process
of proposing new emissions standards for this engine category, the purpose of this
research was to generate information to address these issues. Concerns that high tank
fuel temperatures in gasoline-powered industrial equipment could cause high evaporative
emissions were also addressed.

Approach - With the assistance of the EPA, SwRI selected the test site and a list
of potential test equipment. After on-site screening, two LPG-fueled forklift trucks with
three-way catalyst systems installed for more than 4,000 hours were selected for the test
program. In-use operating data was taken and analyzed, and later used for the
development of a new transient cycle. Performance of the engines and emission control
systems from the two forklift trucks was evaluated at Southwest Research Institute's
Department of Emission Research laboratory.

Results - Two forklift trucks from "Trout Blue Chelan Apples and Pears," located
in Chelan, Washington were selected for the test program. The two Hyster-made forklift
trucks were powered by a GM 181 c.i.d. and a Mazda 121 c.i.d. engine. They had both
been retrofitted with Terminox ™ closed-loop fuel control and three-way catalytic converter
muffler systems marketed by Engine Control Systems, Ltd.

Several hours of in-use operation data including vehicle speed, engine speed,
throttle position, manifold absolute pressure, and intake and ambient temperature were
logged at the site. Subsequently, the engines and emission control systems were shipped
to SwRI for emission tests, and replacement rental forklift trucks were provided for the end-
user.

Steady-state emission testing using the ISO 8178 seven-mode C2 cycle, as well as
a 36-mode map was used to assess the impact of deterioration of emission control
components on both engines. "Best NOX" calibrations were developed for both engines in
order to assess the performance level potential. The highlights of the steady-state
emission results are summarized in the following table.

      Two, five-minute segments of operating data were selected from each forklift truck,
representing a most typical portion, and a most transient portion, respectively.  Together
with a five-minute portion from the welder cycle, they were used as the building blocks for
a new transient cycle for these type engines. The two engines were also tested using the
FTP, Backhoe Loader (BHL), Backhoe Loader-Crawler Tractor (BHL-CT), and Welder
transient cycles.  Brake specific emissions and tailpipe emission concentrations were
recorded. Results are summarized in the following table.

REPORT 08.03661 & 08.03377

-------
      For the fuel sensitivity investigation, a mix of 90 percent propane and 10 percent
butane, representing the lower quality end of the  HD10 LPG  specification, was used.
Results with the new forklift cycle and the old catalytic muffler on the Mazda  engine
showed an  increase in  brake  specific CO and  NOX emissions of 25% and 40%,
respectively.

      Conclusions - It was determined that long term catalyst  durability was very good.
Good emission control system performance throughout a 5,000-hour useful life period will
require periodic maintenance. It is likely that at least once during the useful life period, the
oxygen sensor will have to be replaced.

      Although the five transient test cycles are significantly different from one another,
emissions levels were very similar. All fell below the worst case  of 14 g/hp-hr CO and 2.8
g/hp-hr THC+NOX.

I. INTRODUCTION
Off-road equipment powered by gasoline and LPG engines over 19 kW contributes
significantly to the South Coast Air Basin's mobile source emissions inventory. In October
1998, the California Air Resources Board finalized emission standards for nonroad spark-
ignition engines rated over 19 kW (large SI engines). The Environmental Protection
Agency has also started the process of proposing new emission standards for this engine
type. Prior to this research, there was limited information on the durability of emission
control systems in industrial applications. Furthermore, there was little information
available to describe typical engine operation, especially with respect to the degree of
transient operation.

The primary objective of this project was to develop information regarding the
emissions durability of LPG-fueled large spark-ignited engines. With the assistance of the
EPA, SwRI selected a test site and two LPG-fueled forklift trucks with three-way catalyst
systems with more than 4,000 hours use. Forklift truck operating data were taken for
development of a new transient cycle. The engines and emission control systems from the
two forklift trucks were then tested at Southwest Research Institute's Department of
Emission Research.

Test matrix Tables 7 and 8 should be used to identify steady-state hardware
configurations throughout this report. Tables 12 and 14 serve the same purpose for the
transient test results.

II. FIELD MEASUREMENTS

A. Background

In Task 1 of the project, SwRI measured in-use engine operational parameters (load
and speed) on two LPG-fueled forklift trucks fitted with closed-loop fuel control systems
and three-way catalytic converters that had accumulated 4,000-6,000 hours of operation.
With the assistance of the EPA, SwRI selected the test site and a list of potential test
equipment.

B. Test Site

The selected test site was the packaging plant and warehouses of "Trout Blue
Chelan Apples and Pears," located in Chelan, Washington. Trout is one of the main apple
growers in the state. Currently, they have approximately 60 LPG-fueled Hyster and
Caterpillar forklift trucks retrofitted with Terminox™ three-way emission control systems
marketed by Engine Control Systems Ltd.'of Ontario, Canada. The Terminox systems
were installed by the local Hyster dealership and by Trout Apple's two maintenance
mechanics.

Operation at this site was representative of forklift truck applications, with high
usage and minimal maintenance. However, a detailed log of repairs and maintenance was
kept for each of the forklift trucks.

C. Selection of Forklift Trucks

The selection criteria were:

emission control system hours of use (>4,000 hours desired)
system integrity assessed using a diagnostic tool and tailpipe
emissions levels, and
general engine and forklift truck condition.

Table 1 summarizes information for the trucks inspected.

1. Truck No. 29

This was the first truck examined. Emission control system operation was
found to be within parameters, and instrumentation with the data logging equipment was
begun on February 14, 2000.

2. Truck No. 28

This was the second truck examined for testing. It was taken out of service
and parked in the work area during the morning of February 15, 2000. While parked and
prior to any work being performed on it, the electrical harness caught fire due to a short
circuit.
3.
Truck No. 32
This truck was brought to the work area after truck no. 28 was declared
irreparable in useful time. The Terminox system control box was not working. An attempt
was made to replace a blown fuse in the control box. The new fuse was immediately
blown, indicating a short circuit in the control box. The control box from truck no. 28 was
removed and installed on truck no. 32 with a new fuse. The closed-loop control system
was then found to be working properly. After instrumenting the truck, the engine was
started, and a short engine warm-up procedure was performed prior to emission testing.
Fast warm-up is typically achieved at WOT (wide-open throttle) with full tilt on the mast.
Less than two minutes after beginning this procedure, the hydraulic pump shaft broke,
REPORT 08.03661 & 08.03377
Page 3 of 77

rendering the truck unusable. After-hours service support was summoned from the local
Hyster dealership to change the pump.

A no-load emissions check showed that the catalytic converter muffler was
inactive. The counterweight was taken off to gain access to the muffler. It was removed,
and it was observed that retention of the ceramic substrate had been lost. The catalytic
muffler, manufactured by Engine Control Systems Ltd. (P/N 600031W, S/N 57551), was
set aside for future failure mode investigation. The catalytic converter muffler (S/N 7922)
from truck no. 28 (disabled due to the electrical harness problem) was removed and found
to have the same type of failure. It, too, was set aside for future failure mode investigation.

4. Truck No. 30

The same type of catalytic converter muffler failure was found (S/N 7926).
It, too, was set aside for future failure mode investigation.

5. Truck No. 16

Although the closed-loop fuel control system appeared to be working well on
this truck, tailpipe emissions showed a rich air fuel ratio, favoring high NOX conversion.
Given the otherwise normal operation of the truck, the likely cause was suspected to be
02 sensor condition. A new sensor was installed, proving the diagnosis right. Emissions
characteristics changed to the opposite extreme - lean mixture under load with low NOX
conversion. After the emission test, the old sensor was reinstalled on the truck with the
data logging instrumentation. The driver commented that this truck ran for only eight hours
on a bottle of LPG, while all the other trucks that he has operated ran in excess of twelve
hours per bottle.

D. Tailpipe Emissions

Tailpipe emissions measurement was used as part of the screening process, and
to identify if any exhaust system leaks were present. Since no leaks were detected on the
two forklifts selected, it was decided to ship only the engines to SwRI for subsequent
testing.

A four-gas ECOM S portable analyzer, made available on loan by Engine Control
Systems Ltd., was used for emissions measurement. All of the catalytic converter mufflers
tested had a NPT port after the catalyst, allowing connection of the sampling probe.
Engines and catalysts were warmed up prior to emissions sampling. Results are
summarized in Table 2.

E. Data Logging Instrumentation

Trucks no. 16 and 29 were selected for detailed emissions testing at SwRI. Before
the engines were removed from the trucks for shipment, the duty cycles and operating
characteristics of the trucks were to be documented. The trucks were instrumented, and
the following data representing normal operation were logged at 5 Hz:

engine speed
manifold absolute pressure (indicative of engine load)
throttle position
vehicle speed
intake air temperature
ambient air temperature

A magnetic pickup was used on the alternator pulley fan blades for engine speed
input, as shown in Figures 1 and 2. The engine speed multiplier was determined using an
optical tachometer pointed at the crankshaft pulley.

Manifold absolute pressure (unported vacuum) was used as an indirect indication
of engine load, as shown in Figure 3. New air filters were installed in both trucks.
Barometric pressure recorded at the test site was 28.84 in. Hg., approximately 0.5 in. Hg.
lower than at the time the pressure transducers were calibrated at SwRI.

For measurement of throttle position, a rotary potentiometer was attached to the
throttle valve shaft via a flexible link, as shown in Figure 4. Zero percent and 100 percent
open throttle positions were calibrated on each forklift truck.

Vehicle speed data were based on the rotational speed of the forklift's front wheel.
A 184-tooth ring (from an engine flywheel) was attached to the inner side-wall of the tire
so it would not get torn during operation. A magnetic pickup determined wheel rotation
speed (see Figures 5 and 6), which was converted to vehicle speed.

Temperatures were measured using K-type thermocouples. A thermocouple was
attached to the air filter housing on each truck, as shown in Figures 7 and 8.

The trucks were fitted with flags for ease of identification on the video recording.
Truck No. 29 had a yellow flag, and Truck No. 16 had a flag with blue stripes on a white
background, as seen in Figures 9 and 10.

At the invitation of the EPA project manager, two representatives from NACCO
Materials Handling Group, Inc. witnessed the forklift truck instrumentation and data logging.
Mr. Curt Schulz, P.E. (Tel: 503-721-6927) and Mr. David R. Smith (Tel: 503-721-6927) of
NACCO's Counterbalanced Development Center assisted with instrumentation efforts.

F. Duty Cycles

Forklift truck operators were assigned specific trucks and tasks, therefore it was not
possible to switch operators on the test trucks.

1. Truck No. 29

This forklift truck was used to feed the automated packaging line with apples.
It would pick up four crates of 3,850 ± 50 Ib total weight (approximately 80 percent of the
lift capacity) from the cold storage areas, and bring them to the conveyor lines. If there was
no space on these lines, the crates were placed in front of them. Lift height on the
conveyors was 19 inches. The crates were of cubic shape with a side of 46 inches, stacked
eight high in the cold storage areas, therefore, the pick-up height was almost 200 inches.
The duty cycle between pick-up and drop-off was 90 ± 10 seconds. Approximately six
hours of operation were logged on this truck. This activity is illustrated in Figure 11.

2. Truck No. 16

This forklift truck was used to feed the automated packaging line with packing
material. It would pick up skids of 800 ± 50 Ib total weight (approximately 23 percent of the
lift capacity) from different storage areas, and bring them to the conveyor lines. Its mode
of operation had frequent engine shut-downs, since the operator had to partially unpack
or unwrap the freight. The unloading area was very narrow, and required a lot of small
maneuvers. Approximately four hours of operation were logged on this truck. This activity
is illustrated in Figure 12.

Operating details for each truck were recorded on 8 mm videotape. The time
stamp of the images has an offset of approximately 2 hr and 2 Vz minutes to the internal
clock time of the dataloggers. After the operational characteristics of each truck were
recorded in detail, the camera was placed at a vantage point to record activity in the
unloading areas.

G. Field Measurements - Data Analysis
The first step of the data analysis was the validation and subsequent filtering of the
logged data following the instructions of the U.S. EPA Program Manager. For this purpose,
a data template was created with a segment length of 30 seconds. The entire data sets
for both trucks were scrolled on the computer screen, visually checked for consistency,
continuity and transducer drift, and the time stamps for the idle periods, and cold and
warm engine starts were logged.

Since the purpose of Task 1 was principally transient operation characterization, it
was decided that every idle period of 20 seconds or longer would be removed from the
data set by truncating all but the first and last one to three seconds. The variation in
length, of one to three seconds, of the beginning and end time intervals of a 20-second or
longer idle period was necessary to ensure a natural continuity of the logged engine data.
Engine starts were also filtered out. A summary of the data filtering for the two sample
populations is presented in Table 3. No "smoothing" was applied to any of the recorded
parameters.

The EPA asked for scatter plots and frequency distribution analysis of the main
engine operating variables (engine speed, throttle position, and manifold absolute
pressure). Appendix A Figures A-8 through A-19 present the scatter plots for each truck
based on filtered and unfiltered data sets. Although almost one third of the logged data
was removed from each of the sample populations (data sets), there are minimal
differences between the scatter plots based on filtered and unfiltered data sets. However,
in the area of the plots corresponding to engine speed below 600 rpm and at zero percent
throttle position, the deletion of the segments corresponding to engine starts is visible.

During the data validation process, it was observed that the throttle position
transducers on both trucks had drifted from their original calibrations (0 to 100% throttle)
by less than ±3 percent. The recorded values were re-normalized using the following
algorithm:
TPSW = (TPSorig - TPSm]n)/(TPSmax - 7PSmin) x 100
where:
TPS,,

REPORT 08.03661 & 08.03377
Page 15 of 77

-------
TPSmin - minimum recorded throttle position (<0)
TPSmax - maximum recorded throttle position (> 100)

For statistical analysis, each of the three parameters of interest (engine speed,
throttle position, and manifold absolute pressure) was broken down into predetermined
ranges, and data points were then binned in cells bounded by these ranges. The relative
frequency of occurrence (RFO) for each cell was defined as the number of occurrences
counted in a given cell, divided by the total number of occurrences (number of data points
in the population). Therefore, the sum of the RFOs for each analyzed parameter adds up
to 100 percent.

Although the analysis of engine speed is based on raw, un-normalized data, a direct
comparison between operating characteristics of the two different trucks is still possible
since both had the same idle speed (600 rpm) and almost identical governed speed (2700
rpm). It was observed from the raw data plots that the mechanical engine speed governor
on Truck 16 provided tighter and more precise control, while the pneumatic engine speed
governor on Truck 29 allowed brief "over-speed" excursions to 2800 rpm.

For the frequency distribution plots in Figures 13 through 19, bars representing RFO
values for the different cells are centered on the upper limit of each range. Consistent with
on-site observations, RFOs for Truck 16 show that it had a lighter duty cycle, lifting
payloads of 25-30 percent of its capacity, and driven almost exclusively at closed or part
throttle. This can be concluded from the fact that although both trucks have almost
identical RFO numbers for the idle speed, Truck 16 has an RFO only about one-tenth that
of Truck 29 for the 0-2 percent throttle position cell. For all other cells below 40 percent
throttle position, Truck 16 has higher RFOs than Truck 29 (Figures 13 and 14). Truck 16
also has higher RFOs than Truck 29 in the low engine speed range from 800 rpm to 1500
rpm. For engine speeds above 1600 rpm and throttle positions above 40 percent, Truck
29 has higher RFOs. Results of statistical analysis of engine speed and throttle position
are presented in numerical format in Appendix B, Tables B-1 and B-2.

they are air intake configuration-specific (see Figure 15 and Table B-3).  However, since
manifold absolute pressure is proportional to load, they appear to correlate well with the
two different characteristics of the duty cycles observed for the two trucks.

      A better characterization of modes of operation for the two trucks is shown in 3-D
histograms of throttle position vs. engine speed (see Figures 16 through 19 and Table B-4).
These figures clearly show the baseline characteristics for each of the populations.

                    I. STEADY-STATE EMISSIONS RESULTS
      Following collection of on-site operating data, the local Hyster dealer removed the
engines and accessories from the two trucks, and the engines and accessories were
shipped to SwRI for emissions testing.  These trucks were replaced with equivalent rental
equipment  for the duration  of  the  testing program.   New, replacement  emission
components, as well as the necessary engine diagnostic and programming tools were
procured.

      The  main goal of this  project was the assessment of emission control system
durability by examining the performance deterioration of three-way catalyst systems
installed on two forklift trucks with more than 4000 hours of use. To determine sources of
deterioration, individual emission components were replaced with new components, and
the engines were retested.  Both the Mazda and the GM engines completed steady-state
testing in the following configurations:

            "As Found" (AF)                      engine out - no catalyst,
                                                old (aged) catalyst (OC),
                                                new catalyst (NC)

            "Fueling adjustments" (F) (if necessary) engine out - no catalyst,
                                                old (aged) catalyst (OC),
                                                new catalyst (NC)

            "New Oxygen Sensor" (NS)            engine out - no catalyst,
                                                old (aged) catalyst (OC),
                                                new catalyst (NC)

            "Maintenance" (M)                    engine out - no catalyst,
                                                old (aged) catalyst (OC),
                                                new catalyst (NC)

            "Best Calibration" (BC) for NOX         engine out - no catalyst,
                                                old (aged) catalyst (OC),
                                                new catalyst (NC)

      Each of the above 15 configurations was tested in the seven shaded modes listed
in Table 5, which were used as the basis for the ISO 8178 C2 cycle calculation. Mazda
engine mode 22 was found to be considerably leaner than the other modes.  Mixer "fueling
adjustments" (F) were made for this mode, andithe engine  was then retested to show the
effect of this adjustment. The periodic maintenance procedure, performed in accordance
with  the OEM service manuals, consisted of spark plug replacement, ignition timing
adjustment, valve lash adjustment, and cleaning of the mixer. A "best calibration" (BC)for
NOX  was developed, and  emissions map data covering all the  points  in Table 5  was
obtained. Rated speeds were determined as follows:

      2)
      3)
      4)
Normalization of lug curve.  Normalize the lug curve by:
            - Identifying the point (power and speed) on the lug curve
              where maximum power occurs;
            - Normalizing the power values of the lug curve by dividing
              them by the maximum power and multiplying the resulting
              values by 100; and
            - Normalizing the engine speed values of the lug curve by
             dividing them by the speed at which maximum power occurs
              and multiplying the resulting values by  100.

Determination of rated speed. Calculate the rated speed from the following
speed factor analysis.
            - For a given power/speed point, the speed factor is the
             normalized distance to the power/speed point from the zero-
             power, zero-speed point.  The value of the speed factor is
             defined as:
               Speed factor=^ (power)2+(speed)2

Determine the maximum value of speed factors for all the power/speed data
points on the lug curve.  Rated speed is defined as the speed where the
maximum value for the speed factor occurs.
      Since the  rated speed definition described above differs  from  the ISO 8178
procedure, the Mazda engine was also tested referencing the true rated speed of the
engine, at which maximum power occurs. This result is presented as mode 37, and may
be compared to  the mode 36  result, which uses the  above described  rated speed
definition.  Differences in rated speed and power for the Mazda and GM engines are
shown in Table 4.

a C2 modes are bold and shaded. Note that modes 19 and 20 depart from the pattern to fit the C2 cycle.
      Forklift engines operate at idle with high auxiliary loads from the engine cooling fan
and hydraulic pump. These loads were simulated in the test cell with the dynamometer,
since both  the cooling fan and the hydraulic pump were  removed in the test stand
configuration. To maintain the target 600 rpm idle speed,  a load of over 30 Ib-ft was
applied to the Mazda engine, and a load of 60 Ib-ft was applied to the GM engine.  For the
no-load  idle test mode, the speed governor had to be  deactivated, and the idle speed
readjusted. Also, at no-load idle, the catalysts were below their light-off temperatures, and
therefore not reducing emissions.  In order to cover both real life operation and the ISO
procedure requirements, two idle modes were run on both engines in all tests.  Mode 1
was idle with load, typically described as Curb Idle Transmission Torque (CITT). Mode 1A

was no-load idle. Through the addition of these supplemental modes, a total of four
different composite emissions results could be calculated for the Mazda engine, and two
different composite results for the GM engine. These are summarized in Table 6.
Differences in emissions were generally small, with a small NOX response observed with
the loaded idle mode.

A. Mazda Engine (Truck 16)

As identified on-site at Trout Apples, the oxygen sensor on this engine was
malfunctioning, allowing operation at richer than normal air-fuel ratios. However, during
engine start-up in the test cell, it was observed that the engine was running lean. A crack
was found at the base of the throttle body which had become "unplugged" as a result of
the steam cleaning of the engine prior to test cell installation. Accumulated dirt had
apparently kept the crack sealed when tailpipe emission measurements were being taken
on-site. A new throttle body was procured and installed during the maintenance procedure.
For initial testing, an epoxy patch was applied over the crack. During the first set of "As
Found" tests, it was observed that in Mode 22 (intermediate speed, full load), the engine
was running very lean. For subsequent tests, this was corrected by opening the power
valve from its initial position of approximately 2/3, to full rich.

      Closed-loop fuel control  systems are currently being installed on  LPG-fueled
industrial engines to minimize personnel exposure to CO when the equipment is used
indoors. As expected, the original calibrations of the closed-loop fuel control systems on
both the GM and the Mazda engines were found to have a lean bias for maximum CO
reduction.

      Mazda engine original calibration, C2 cycle emission results (Figures 20 and 21) for
tests D through G, show that the emissions impact of the malfunctioning original oxygen
sensor, is far more significant than catalyst aging.  The old oxygen sensor displayed a
slower response and a shift in the lean/rich  switch point causing a 0.12  air/fuel ratio
decrease  (shift towards richer mixture) in the average air/fuel for the C2  cycle.  The
average air/fuel ratio was calculated from the recorded modal averages for all the C2 cycle
modes, excluding idle.  Replacing the old oxygen sensor with a new one re-established the
intended lean bias of the calibration, causing the C2 cycle brake specific CO to drop 98.5%
for the tests with the original catalytic converter muffler, and 97.4% for the new catalytic
converter  muffler.   As a  result, the brake specific  (NOX+THC)  doubled in  both
configurations. After the mechanical fuel flow adjustment to  cure the  lean operation in
REPORT 08.03661 & 08.03377

-------
mode 22, and maintenance work that included the replacement of the old oxygen sensor,
results showed that this lean bias, original calibration did not meet GARB standards for
NOX+THC. However, it was noted that in the original "as found" configuration with the old
defective oxygen sensor, C2 cycle emissions were in compliance.

Subsequently, a "best NOX" calibration was obtained through four iterations. Using
calibration 4, C2 cycle results of 3.16 g/hp-hr CO and 0.51 g/hp-hr THC + NOX were
obtained for test (R) with the original catalytic converter muffler. Corresponding results for
test (T) with the new catalytic converter muffler were 1.56 g/hp-hr CO and 0.58 g/hp-hr
THC + NOX. Throughout the steady-state tests on the Mazda engine, the new catalytic
converter muffler had better CO conversion efficiency, but slightly worse NOX conversion
efficiency, compared to the original part, although the supplier stated that there are no
catalyst formulation differences between the two units. Therefore, based on the last results
with the "best NOX" calibration, it can be noted that over 4,000 hours of use, this catalyst's
performance deterioration caused a twofold increase in C2 cycle CO emissions and no
change in NOX emissions. It was also noted that due to the flexibility offered by the
programmable closed-loop fuel control system used, an "indoor-use friendly" calibration,
minimizing both CO and NOX could be obtained. C2 cycle results for calibration 2, used
in test P in conjunction with the new oxygen sensor and original catalytic converter muffler,
are 0.78 g/hp-hr CO and 1.26 g/hp-hr THC + NOX.

Figures 22 and 23 present the full emissions map for this engine, with emissions
plotted versus normalized engine speed and normalized load. These results were obtained
using the "best NOX" calibration in conjunction with the new oxygen sensor and original
catalytic converter muffler. The emissions map shows that all measured modal emission
levels fell below CARB standards. Further, calibration optimization and mechanical fuel
adjustments could reduce the high full load CO emissions. Also note that the no-load idle
emission levels presented in the figures are expressed in g/hr.

B.    GM Engine (Truck 29)

      One of the two identical substrates inside the catalytic converter muffler from Truck
29 was loose, and was reduced in volume by abrasion due to vibration. The catalyst parts
were removed from the original converter and re-canned with a loss of only 18 percent in
total catalyst volume. Results of a failure mode analysis are presented in Section VII.

      Table 8 contains the description of the individual 8-mode tests performed on this
engine, and the corresponding configuration identification codes used in this report.

      The GM engine original calibration, C2 cycle emission results (Figures 24 and 25)
for tests GC through GE show a much smaller emissions impact of oxygen sensor aging
than on the Mazda engine. Furthermore, emission results for the "as found" configuration
on this engine were very similar to Mazda results after its malfunctioning oxygen sensor
was replaced. In spite of the 18% loss in volume of the original catalyst, NOX emissions
were lower than with the new unit for all the original calibration tests.  However, the "best
NOX" calibration results show a deterioration by a factor of 6.6 for C2 cycle CO in the new
catalyst/old catalyst comparison, and a corresponding threefold increase in NOX+THC for
the test  with the original catalytic converter muffler.   Note that  these  proportional
differences are magnified by the low levels being compared.

       All  results  are  included in the appendices.  Results from steady-state tests
performed on both engines are presented in Figures A-40 through A-73, Appendix A.
Figures A-40 through A-43 show C2 cycle results for both engines using both old and new
catalysts.   Figures A-44  and A-45 show catalytic muffler inlet temperatures for both
engines.  Figures A-46 through A-63 show detailed modal emissions results for both
engines, both with and without catalysts.  Figures A-64 through A-73 present the full
emissions map for both engines, with emissions plotted versus engine speed and load.
Detailed numerical results for both engines are in Appendix B, Tables B-5 through B-27.

      Approximate D2  cycle  composite emissions, pertinent  to  constant  speed
applications, were calculated using emission levels recorded in modes 36, 34,33,31, and
30. Results are approximate because the load factors in modes 34 and 33 are 5 percent
lower and higher, respectively, than the standard mode definitions for the cycle.  Results
are listed in Tables B-16 and B-17 for the Mazda engine, and Tables B-23, B-24, B-26, and
B-27 for the GM engine.

                     IV. TRANSIENT CYCLE DEVELOPMENT
A.    Defining Typical Data Segments

      Segments of data collected from the operation of the two forklift trucks were
individually identified to represent a "typical" interval of truck application.  Each "typical"
cycle was developed based on data segments selected according to rankings of chi-square
statistics. The most typical cycle for each forklift was defined  as the contiguous 5-minute
segment of data that most closely represented the speed and throttle populations depicted
from the entire forklift data collection.  The chi-square statistic was computed for each 5-
minute moving window data segment.  The segment with the smallest y? statistic identified
the 5-minute segment that contained the speed and throttle data points most similar to the
overall forklift data population. The following steps were used to rank  data segments for
developing typical cycles from gathered in-use data:

             1)    Define "bins" sized at 200 rpm for speed. Throttle bins varied because
                  of the skewness of the throttle values. Bin intervals for throttle ranged
                  from 2-30%. The same interval bins for speed and throttle were used
                  for both forklift trucks. Intervals were not uniformly spaced.
            2)    Sort entire data file (34,898 observations for Truck 16, and 66,781
                  observations for Truck 29) into speed and throttle bins.
            3)    Compute a frequency table to indicate the number of observations
                  contained in each bin.
            4)    Define data segments starting at every 1-minute time interval. Data
                  segment length is 5 minutes.
            5)    Sort each 5-minute data segment into similar speed and throttle bins.
            6)    Compute a chi-square statistic3 to compare the frequency distribution
                  of each sample window against the population frequency distribution
                  for each individual forklift.
            7)    Repeat steps 4-6 for all 216 5-minute data segments for Truck 29,
                  and all 111 5-minute data segments for Truck 16.
            8)    Sort the  chi-square  statistics in  increasing time order,  and by
                  increasing chi-square  rank.
              The chi-square test statistic is:
            where O}\s the observed frequency in the ith interval of the 5-minute sample
            window, and Ej is the expected frequency of the ith interval based on the
            frequency distribution of the entire time of operation (population).

      Table 9 lists all the identified typical cycle segments for the two forklift trucks. The
selections used are shaded. For Truck 16, the segment with the best chi-square statistic
had too much idle operation to be considered valid.

B.    Defining Highly Transient Delta Speed and Delta Throttle Data Segments
      High transient operation was defined as in-use forklift operations having the largest
change in power based on either speed or throttle changes.  Development of high transient
cycles for speed and throttle required a method for assessing the extent of transient speed
and throttle within each 5-minute contiguous data segment. Incremental delta speed and
delta throttle values were computed and summed to discriminate between data segments
for defining the most highly transient 5-minute data segments.  For developing  the high-
transient cycles, the data segments having the largest summed value for the delta speed
and delta throttle were selected for use in developing the high transient speed  and high
transient throttle cycles.  The following steps  were used to rank data segments  for
developing high transient cycles from gathered in-use data:
            1)
            2)

REPORT 08.03661 & 08.03377
Compute  delta  speed  and delta throttle  values for each ith
observation as:
Delta Speed  =  ABS(Speed(i+1) - Speed(i)) where i=observation
number
Delta Throttle = ABS (Throttle(i+1) - Throttle(i)) where i=observation
number
Data were sampled at every 1-minute interval starting at time=0. The
data segment length was 5 minutes.
Represent each  5-minute data segment by the following two values:
(1) sum of the delta speed values, and (2) sum of the delta throttle
values.
Summarize data by (1) increasing time order, (2) decreasing order of

C.    Torque Measurements

      Since torque information could not be obtained directly in the field, it was necessary
to create a torque signal in the laboratory based on available data. Initially, it was thought
that torque information could be developed from a correlation of in-field throttle position,
engine speed, and manifold absolute pressure data with a map of steady-state engine
operation. After further consideration, a more direct approach was formulated where the
engine was commanded in the test cell so as to duplicate the field operating data.  This
required development of new control algorithms.

      The engines were installed sequentially in Cell 2, where all the transient test work
for this project was conducted. They were both brought to the "as found" configuration,
with the old oxygen sensor, catalyst, calibration, and fuel adjustments.  A lug curve was
generated. The results from three runs for each of the two five-minute segments were
averaged. A very good duplication of the field operation was achieved for the two,  five-
minute segments on both engines as shown in Figures 30 and 31. The measured average
torque and speed traces for both engines were normalized using the corresponding "as
found" engine maps (lug curves) following the FTP procedure.

D.    New Cycle Construction

      The new cycle was generated using the normalized segments  in this order:

            Truck 29    - 5   minutes "most typical" operation
                        - 2.5  minutes "highest level of transients" operation
            Truck 16    - 2.5  minutes "highest level of transients" operation
                        - 5   minutes "most typical" operation
            Welder cycle - 5   minutes

      The five-minute segment of the welder cycle used was identified by the EPA Project
Manager. Figure 32 shows  the new cycle.

                   V. TRANSIENT TEST EMISSION RESULTS
      Tables 12 and 14 contain all the transient test emission results for both engines in
chronological order. Tables 13 and 15 contain a summary of the results with averages for
repeated runs calculated where applicable. For each run, the following details are listed:

            Test number
            Run  number for data logged with LabVIEW platform 1 (LV1)
            Run  number for data logged with LabVIEW platform 2 (LV2)
            Cycle type
            Cycle duration
            Soak time duration
            Hardware configuration (old catalyst, new catalyst, etc.)
            Calibration identifier
            Brake-specific emissions

      During the first part of the transient work targeted mainly at torque measurements,
emission performance  was also recorded. Subsequently, the short five-minute test runs
were also used for the "best  NOX" calibration optimization, idle fuel mixture adjustment
strategy, and old catalyst and old sensor versus new catalyst and new sensor emission
performance comparison.  Emission results in Table 12  for the Mazda engine over the
"most typical" and the "highest degree of transients" cycles show that, at least for these
short cycles, NOX emissions can be reduced by a minimum of 50% by carefully controlling
idle fuel mixture at stoichiometry. In the "as found" configuration,  the Mazda engine
generated higher  CO and  NOX emissions on the highly transient cycle segment. The
reverse was observed in the "best calibration" test, where higher emissions were observed
with the "typical" cycle  segment.  The GM engine had the exact opposite trend.

A.    Transient Cycles

      Five 9ignificantly different  transient cycles were used  to  test the emissions
performance of the two engines. These cycles were:

            •      Heavy-duty on-highway Otto-cycle federal test procedure (FTP)
            •      Backhoe Loader cycle (BHL)
            •      Combined Backhoe Loader - Crawler Tractor (BHL-CT) cycle
            •      Welder cycle
            •      New cycle

      The Backhoe Loader (BHL) cycle was run on the GM engine, and the Combined
Backhoe Loader - Crawler Tractor (BHL-CT) cycle was run on the Mazda  engine. The
Backhoe Loader cycle (BHL) and the Combined Backhoe Loader - Crawler Tractor (BHL-
CT) cycle  were  developed  by SwRI under contract for the EPA from  nonroad  diesel
equipment operating data.  Normalized 1  Hz cycle command traces are  presented in
Figures 33 through 36. Due to the hysteresis in the engine governor's speed control and
the resulting impact on torque output, most of the transient tests on both engines were run
with the governor disabled. Cycle tuning efforts were limited to the level  necessary to
ensure the tests were valid representations of emissions performance.

B.    Brake Specific Emissions and Emission Concentrations Control Factors

      Raw exhaust emission concentrations were measured during transient testing on
both engines at 1 Hz.  This information serves two purposes. First, it enables application-
specific fine-tuning of the closed-loop calibration strategy, and second, it helps target the
occurrences of maximum levels of critical pollutants.  A large number of industrial LSI
engines operate indoors, where OSHA regulations mandate maximum allowable ambient
concentrations for both CO and NOX at a 25 ppm level for 8 hours of exposure. Therefore
from a work safety point of view, information on emission concentration is necessary for
ventilation system sizing.  For  dedicated indoor applications, fuel control calibrations
should target minimum levels for both NOX and CO, rather than minimum NOX only.

      1.     Soak Time

            Soak time, which is defined as the period of time between the end of engine
conditioning and the beginning of the actual transient emission test, can have a large effect
on emission results. During the soak, the catalyst bed temperature decreases as a result
of a natural cool down. The longer the soak time, the lower the catalyst bed temperature
at the beginning of the emission test, and therefore the longer it will take the catalyst to
reach light-off  temperature.  GM engine results presented in  Figures 41 and 42 show
emission effects of a 20 minute and a 3 minute soak time, respectively, ahead of the FTP
cycle runs. A 50% reduction in light-off time from 30 seconds to 15 seconds leads to a 60%
reduction in CO levels, from 2.72 g/hp-hr to 1.02 g/hp-hr, and a 50% reduction in HC. A
similar trend was observed in the backhoe loader cycle  runs, as shown in Figures 46 and
47.  However, with  this  cycle, the reduction in  before light-off emissions yields a
proportionally smaller impact on total brake specific emissions.  Both  CO and HC were
reduced  approximately 30%.  For all five transient  cycles, light-off temperatures were
always reached in less than two minutes from the beginning of the cycle, independent of
the length of the soak time, as shown Figures 37 through 51.

      2.     Calibration

            The term "best calibration" used throughout this report refers specifically to
a maximum NOX reduction goal. The same calibration strategy was used on both engines,
for both steady-state and transient tests. Reported performance levels are therefore not
representative of an optimization effort that would take  into consideration the CO versus
NOX trade-off, necessary for indoor applications. In this context, it is conceivable that the
CO tailpipe concentrations could be further reduced.  The very high before catalyst light-off
emissions recorded in Figures 37, 39, 44 and 45 for the Mazda engine  could be reduced
by further leaning of the idle mixture. Further improvement could also be obtained by fine
tuning the calibration to the specific application. A welder or pump calibration should be
different from that of a forklift truck, which in turn could have two different calibrations for
indoor or outdoor use.

      3.    Closed-Loop Fuel Controller

            Both  engines had the  same  model of closed-loop fuel control system
installed. This five to six year old, first generation digital closed-loop fuel controller uses
engine speed for its internal clock frequency. Therefore, its reaction time increases with
a decrease in engine speed. This leads to increased A/F amplitude variation around the
stoichiometric control point at low engine speeds. For steady state operation at low engine
speeds, the impact on emissions is minimal, but still noticeable as presented in Figures 22
and 23.  The new transient cycle is characterized by a high frequency of fast throttle
opening and closing at low engine speeds. The high CO peaks presented in Figures 48
through 51, show the cumulative effect of +/- 0.8 A/F ratio fluctuations coupled with the
strong rich bias of the calibration. Nevertheless, a cycle-specific, and therefore application-
specific optimization of the calibration could have significantly  improved  performance.
Also,  second generation  controllers with  an internal,  engine speed-independent clock
frequency, could further reduce emissions levels through more precise air-fuel ratio control.

      4.    Catalytic Converter

            The two engines were fitted with catalyst sizes that yielded comparable
exhaust gas space velocities. However, the loss of retention of one of the substrates in
the original GM engine catalytic converter muffler led to an 18% reduction in total catalyst
volume. The combined effects of the volume reduction and aging allow a clear definition
of the deterioration trend for the original system installed on this engine. FTP cycle results
presented in Figures 42 and 43 show a threefold increase of peak CO concentrations,
from 1000 ppm with the new catalyst to 3000 ppm with the original catalyst. Brake specific
CO emissions increased in excess of 300%, from 1.02 to 4.42 g/hp-hr. NOX increased only
19%,  from 0.73 to 0.87 g/hp-hr.  These correspond to conversion efficiency losses of 6 -
16% for CO and less than one  percent for NOX.  If a  98%  CO conversion efficiency is
assumed for the new catalyst, a fourfold increase of tailpipe emissions would correspond
to a 92% conversion efficiency  for the  original catalyst. Similarly, for a 96% assumed
efficiency for the new catalyst, the same deterioration ratio would correspond to a  80%
efficiency for the old catalyst (98% down to 92%, or worst case 96% down to 80%.)
Figures 38 and 39 show similar deterioration ratios for CO for this engine when tested over
the new cycle, but the corresponding loss of CO performance is smaller. NOX effectively
doubled from 0.30 to 0.62 g/hp-hr for these runs.

            Both transient and steady-state results obtained with the Mazda engine show
that the new catalyst produced better CO conversion, but worse NOX conversion than the
original catalyst. FTP tests 4 and 5 (run name H7) in Table 12 show CO levels of 11.96
g/hp-hr with the old  catalyst, versus 3.10 g/hp-hr with the new catalyst. NOX results with the
old and new catalyst were 1.13 g/hp-hr versus 2.39 g/hp-hr,  respectively.   Results
presented in Figures 44 and 45 for the backhoe loader - crawler tractor cycle show a good
match between the  twofold increase in peak CO concentration, and the almost doubled CO
levels compared to the new catalyst. NOX results for this cycle show a 22% deterioration
on the old catalyst compared to the new catalyst.

      5.    Engines

            Throughout the transient test program, the Mazda engine had higher brake
specific emissions than the GM engine.  This difference can be explained in part by the
different torque output characteristics of the two engines. The smaller displacement Mazda
engine had less torque than the GM, which led to more frequent throttle activity, which in
turn put more demand on the closed-loop fuel control system, adding perturbation to the
air-fuel ratio. Note that the scale for Mazda engine gas concentrations in Figures 37, 44
and 45 is different from the rest in order to accommodate higher peak values.

            As a general observation, it can be stated that although the five transient test
cycles were significantly different from one another, emissions performance levels were
very similar. All fell below the worst case of 14 g/hp-hr CO and 2.8 g/hp-hr THC+NOX.

C.    Fuel Sensitivity Results

      As part of the work statement, a fuel sensitivity test was also performed. In spite of
efforts to obtain information on the composition of an "off spec", worst case LPG fuel, no
usable details were obtained.  After discussions with the  EPA Program Manager, it was
decided to use a mix of 90 percent propane and 10 percent butane as representative of
the lower quality end of the HD10 LPG specification. Emissions data over three runs was
generated using the new forklift cycle with the old catalytic  muffler. Results listed in Table
12 for the Mazda engine show an increase in brake specific emissions of 25% for CO and
40% for NO,

                  VI. FUEL TEMPERATURE MEASUREMENT
      The goal of this test was to measure bulk liquid volume fuel temperatures in the tank
of a gasoline forklift truck in near-continuous operation. A CLARK C500 YS 60 forklift truck
with a  6,000 Ib capacity belonging to Southwest Research Institute's Department of
Emission Research, was used.

      The test was performed outdoors in a completely shaded area during a windless
day. The length of the straight-line, no gradient run was approximately 60 ft. A palletized
weight of 1,200 Ib was used for load simulation. A simple sequence of runs with and
without load, with lifts up to half mast height was carried out for over four hours.  Every
hour, a ten minute break was introduced. The fuel tank was 3/4 full at the beginning of the
test.

      Four thermocouples were installed on the truck for temperature measurement. One
thermocouple was placed in the middle  of  the  tank  for  bulk  liquid temperature
measurement. Another was located above the liquid in the empty volume to measure tank
vapor temperature. A third thermocouple was attached to the outside wall of the fuel tank
in the engine compartment. The fourth thermocouple was attached at mid-height to the
rear leg of the  roll cage  for ambient temperature measurement. Signals from the
thermocouples were sent to a datalogger using a sampling rate of 0.2 Hz (5-second
interval).

      After three hours, the tank bulk liquid temperature reached a plateau of 3-4°F above
ambient temperature. During the ten minute breaks, the engine was not running and there
was no cooling air flow in the engine compartment.   Due to the heat transfer from the
engine, temperatures 8-15°F above ambient were recorded.  This caused the vapor
temperature in the tank to rise 2-3°F above the bulk liquid temperature. It is apparent from
Figure  52 that the vapor temperatures would continue to rise if the soak period were
longer.

        VII. ANALYSIS OF FAILED CATALYTIC CONVERTER MUFFLERS
      Three failed catalytic converter mufflers were discovered during truck selection.
Two of these were retained for analysis by SwRI, and the third was returned to the
manufacturer. Further, upon arrival of the two engines at SwRI, it was discovered that the
muffler from Truck 29, S/N B7923 also had at least one loose substrate based on the
rattling sound it produced while shaken by hand.

A.    Sample Preparation and Measurement Procedure

      Figure 53 shows the Truck 29 catalytic muffler with a welded attachment for test cell
installation. The protrusion  of the weld seam from the circular surface of the cylindrical
body was ground off at both ends of the can for circumference measurements. See Figure
54. These measurements were performed using a Pi-tape. A Pi-tape is used to determine
the diameter of a cylinder with a precision of 0.001  inch and is sold with a certificate of
accuracy traceable to the National Institute of Standards and Technology. The muffler end
caps were cut using a bandsaw allowing further inspection and measurement of the center
sections containing the ceramic substrates.

B.    Failure Mode Analysis

      Upon inspection of the ceramic substrates, it was concluded that none had suffered
from overheating.  In both mufflers, with the serial numbers B 7923 and B 7922, one of the
two substrates in each can had suffered loss of retention  and subsequent mechanical
abrasion from contact with the  metal container.  The intumescent mat had completely
decomposed and was washed away by the flow of exhaust gas. Figures 55, 56, and 57
show details of muffler S/N B 7923. In muffler S/N A 57551, both substrates were reduced
to egg-sized pieces, the final stage of the same failure type.

      The canned substrate assembly consists of the ceramic  monolith, a layer of
intumescent mat, and a rolled sheet metal wrap. The mat serves a dual role of mechanical
retention of the substrate, once the prescribed mounting pressure is ensured, and sealant
so that the exhaust flow can pass only through the catalyst and not around it. In order to
achieve the expected  assembly durability, mat manufacturers prescribe a range of gaps
between the substrate and the metal wrap, that are specific to the kind of mat used. In this
case, a common canning technique called "butt-welding" was used.  A rolled piece of sheet
metal is placed around the mat-wrapped substrate, squeezed until the two edges meet,
and welded. Control of the gap and therefore the mounting pressure is achieved through
accurate control of the length of the metal wrap before rolling. Table 16 contains the
measurement results, material  tolerances, gap calculations based on common  linear
tolerance  stack-up,  and  recommended  gaps for the mat used.  Also,  values for
recommended and as found wrap lengths have been calculated.

     NOTE:     - Substrate diameter and sheet metal thickness tolerances were
                  supplied by the manufacturer of the catalytic converter mufflers.
                - The prescribed gap tolerances for the type of intumescent mat used
                  were found in the product applications catalog.

      The maximum calculated gap based on outside diameter of the can and the worst
case scenario of tolerance stack-up exceeds the maximum prescribed gap for the three
catalytic converter mufflers investigated.

C.    Repair of Test Sample

      The center piece of catalytic converter muffler S/N B 7923 was  cut through the
middle in order to remove the partially damaged substrate  as shown in  Figure 57.
Subsequently, the substrate was machined to a suitable cylindrical shape and re-canned.
Flanges, V-clamps, and welding were used to restore the functionality of the catalytic
muffler, and allowed its use throughout the emission test program. Figure 58 shows the
repaired unit.

      At the end of the program, it again became apparent while handling the  muffler that
a substrate was loose.  It was the second half of the dual bed, which was still  intact when
the body was first cut for inspection. This failure happened during testing at SwRI due to
the above mentioned reasons.  Performance of this catalytic converter muffler may have
been somewhat degraded by a portion of the exhaust flow bypassing the second substrate.
Figure 59 shows details of the failure.
