I. INTRODUCTION
Worldwide dependence on petroleum products and associated economic
and environmental problems have focused attention on the use of alcohols as a
substitute. Alcohols can be produced from both renewable and nonrenewable
energy feedstocks, but have not been widely used to date as primary engine
fuels for transportation uses because petroleum distillates were less expensive
to produce and use. The diesel engine has been used with petroleum fuels for
nearly a century. However, the use of petroleum-based fuels in diesel engine
applications yields relatively high levels of several regulated pollutants, such as
particulate matter and nitrogen oxides, as well as "nuisance" emissions such as
smoke and odor. Diesel powered buses are one of the prime examples of a
diesel engine application which has come under scrutiny due to concerns over
emissions. Methanol fuel is considered to burn more cleanly than petroleum-
based fuels, and it is easily produced from a variety of resources.
In the interest of reducing emissions and dependence on imported oil, the
State Legislature of California directed the California Energy Commission
(CEC) to undertake demonstrations of advanced fuel technologies - emphasizing
methanol. One of these demonstrations consisted of two neat methanol
powered transit buses/^* with one bus developed by Maschinenfabrik
Augsburg-Nurnberg (M.A.N.) of Germany and the other by General Motors
Corporation (CMC). Both methanol buses were placed in revenue transit
service with the Golden Gate Bridge, Highway and Transportation District, to
demonstrate the feasibility of operating methanol-fueled buses in such service.
Smoke (visible particulate) emissions have been reported as low or non-existent
on the two methanol buses, however, the effects of methanol fueling on other
regulated and currently unregulated emissions are uncertain.
Methanol-fueled buses are being proposed, by EPA and others, as a
potential solution to the current diesel bus particulate problem. However,
there are no available data on emissions from methanol fueled buses operated
on a chassis dynamometer, and only limited engine data are available. The
objective of this work was to characterize the emissions behavior of the two
methanol fueled buses'^) used in the California methanol demonstration on
behalf of EPA.
The M.A.N. methanol bus tested in this program is one of many developed
for evaluation throughout the world, and is one of the first to be evaluated in
the United States. The CMC methanol bus represents the first methanol bus
delivered by CMC and is actually a prototype. Both buses represent significant
development efforts for both manufacturers. After about 2 years of operation
for demonstration purposes, the M.A.N. accumulated 45,500 km (28,300 miles)
and the CMC accumulated 30,500 km (18,900 miles).
*Numbers in parentheses designated references at the end of this report.
-------
Exhaust emissions from both buses were characterized over chassis
dynamometer operation at four steady-state conditions and on two transient
test cycles. Emissions characterization included regulated emissions of HC,
CO, NOX, and particulate; along with unregulated emissions of unburned
methanol, selected individual hydrocarbons, and aldehydes. The total
particulate matter was characterized in terms of mass emissions, elemental
content, and soluble organic fraction (SOF).
-------
II. SUMMARY
Use of methanol fueled buses is being promoted as a step toward energy
independence and improved air quality by displacing the use of petroleum based
fuels. The California Energy Commission has sponsored the operation of two
neat methanol fueled city transit buses to obtain in-service data. One of the
methanol buses is a M.A.N. model SU 240 powered by a four-stroke M.A.N.
D2566 FMUH methanol engine utilizing spark ignition. The other methanol bus
is a CMC model RTS II 04, powered by a prototype two-stroke DDAD 6V-92TA
methanol engine utilizing on-board computer control of methanol injection,
scavenging air, and glow plugs to promote compression ignition of the methanol.
The M.A.N. methanol bus uses an exhaust catalyst, the CMC methanol bus does
not.
Exhaust emissions of both neat methanol fueled buses were determined
over various types of chassis dynamometer cycles. Regulated and selected
unregulated emissions were determined at steady-state conditions of cold idle
in neutral, 20 kph cruise, 40 kph cruise, and hot idle in drive, and over the
transient conditions of the central business district (CBD) and the EPA bus
cycles. With the exception of cold idle operation, all test work was conducted
with a warm engine (and warm catalyst on the M.A.N. bus). Emission results
from the M.A.N. and the CMC methanol buses are summarized in Tables 1 and
2, respectively. Methanol fuel economy is given for comparison purposes, but
also to facilitate conversion of the emissions results to a methanol fuel specific
basis. Diesel equivalent fuel economy is given for reference purposes. It should
be noted that although simulated passenger loads (25 passengers with a driver)
were the same for both buses, the CMC chassis was substantially heavier (1900
kg) than the M.A.N. chassis and was equipped with a wheel chair lift.
Warm engine/catalyst emissions of HC and CO from the M.A.N. bus were
very low, indicating that the oxidation catalyst was very effective. Only low
levels of methane (representing most of the total IHC) and formaldehyde
(representing most of the total aldehydes) were noted for warm engine/catalyst
operation over the various test conditions. Emissions of NOX were lower than
typical diesel levels. Total particulate emissions from cold and warm engine
operation were very low (no visible staining on the collection filter). In the
case of cold idle (with little or no catalyst activity), the soluble organic
fraction (SOF) accounted for essentially all the total particulate emission. For
warm engine/catalyst operation, however, the SOF accounted for 10 to 50
percent of the total particulate. Analyses of the SOF and lubricating oil
indicated that the SOF of the total particulate originated as engine lubricating
oil.
Emission levels of total HC (mostly unburned methanol) over both cold
and warm engine operation of the CMC were very high. Unburned methanol
emissions represented 8 to 20 percent of the fuel supplied over some test
conditions. Methane, ethylene, and lesser amounts of other individual
hydrocarbon emissions were noted for the CMC methanol bus. Total aldehyde
emissions were primarily made up of formaldehyde with some acetaldehyde and
lesser amounts of other aldehyde species. The CMC's very high HC (unburned
methanol) and CO emissions, along with very low NOX emissions, are likely due
in part to poor combustion quality. Total particulate emissions for the CMC
methanol bus were lower than for a diesel bus, but greater than expected for an

ffl. TEST PLAN AND DESCRIPTION OF METHANOL BUSES AND PROCEDURES
The intent of this program was to characterize regulated and unregulated
emissions from the M.A.N. and the CMC methanol buses. This section describes
the test plan used in the program. Some of the pertinent specifications of the
buses and their respective engines are given along with some of the properties
of the neat methanol fuel used during this test work. Procedures are described,
including both the test procedures used to generate and acquire emissions
samples and the analytical procedures used to characterize the emission
samples. For the purposes of quality assurance, an assessment of the data
accuracy, precision and completeness is given in this section of the report.
A. Test Plan
The planned program included measurement of both regulated and
unregulated emissions from both methanol fueled buses over six chassis test
cycles as indicated in Table 3.\2) Some analysis of crankcase oil was planned in
connection with analysis of the soluble organic fraction (SOF) of the total
particulate. Since particulate levels were anticipated to be very low, plans to
clean the dilution tunnel were made. Provisions to extract blank filters were
made in order to determine the "background" contribution to the extractable
portion (SOF) of the total particulate. In addition, modifications to the
computer program were planned to process emissions data accumulated on
methanol fuel. Emission samples outlined in Table 3 were to be obtained in
triplicate for each bus and processed individually whenever possible. Therefore,
most of the emissions data to be presented in summary form would be the
results of three determinations.
B. Description of Test Vehicles
Both methanol powered buses were obtained from the California Energy
Commission's "Methanol Bus Demonstration Project" being conducted in
California.'2»3) 7ne buses were delivered to SwRI on behalf of EPA for
emission testing after approximately two years of revenue service in the San
Francisco area. Some of the pertinent descriptive information on both buses is
given in Table 4.
The M.A.N. methanol bus is a model SU 240, and is a standard European
intercity coach as shown in Figure 1. This bus is powered by a M.A.N. D2566
FMUH engine, developed for consuming a variety of low-cetane fuels. This
engine is based on a M.A.N. diesel engine design and has an 18:1 compression
ratio. Ignition of the methanol is accomplished by a timed spark ignition
system.™' This naturally aspirated, four-stroke, in-line 6-cylinder engine is
essentially the same as tested on an engine dynamometer in an earlier EPA
program.(5) Figure 2 shows the engine compartment of the M.A.N. SU 240
inethanol bus with the horizontal configuration of the engine. Figure 3 shows
the spark plug wires. The ignition system and spark plugs are still under
development to extend their service. Power for air conditioning on the bus is
supplied by a small auxiliary diesel engine.

-------
The M.A.N. bus uses a catalyst for exhaust aftertreatment to reduce
emissions of unburned methanol and aldehydes. The exhaust catalyst consists of
two units operated in parallel. Each unit contains about 2.9 liters of Corning
ceramic monolith substrate M 20/400 (20 mil wall and 400 cells/in.2) in an oval
shape (3.2 x 6.7 inch) and handles the flow from 3 of the 6 cylinders. The
catalyst coating was supplied by Engelhard Kali-Chemie GmbH and is described
as a "diesel oxidation catalyst with 1766 g/m^ (50 g/ft^) of platinum." Final
assembly of the units was performed by Zeuna-Staerker AG.
Prior to transport, routine maintenance had been completed and a new
catalyst fitted to replace one which had failed due to loss of spark ignition.
Operation and driveability of the bus were deemed typical and acceptable
before shipment to SwRI. The M.A.N. was received with approximately 45,500
km (28,300 miles).
The GMC methanol bus, shown in Figure 4, is a model RTS II 04, which is
typical of the majority of city transit buses used in the United States. The
methanol engine was developed from the GMC Detroit Diesel Allison Division
(DDAD) 6V-92TA diesel engine. The DDAD 6V-92TA methanol engine shown in
Figure 5 is of two-stroke design and relies on compression ignition of methanol.
Compression ignition of methanol occurs unassisted during high load conditions.
The design relies on control of scavenging air to maintain ignition during
moderate loads. In addition, glow plugs are used to assist light load, idle and
start-up operation of the GMC methanol engine. The methanol engine utilizes
electronically controlled injectors. The GMC methanol bus uses an on-board
computer to vary scavenging air, glow plug operation, fuel delivery, and
injection timing relative to throttle demand and engine parameters. Some of
the control actuators associated with the throttle and the scavenging air
control are shown in Figure 6.(3»6)
Prior to shipment, preventive maintenance was conducted on the GMC
methanol bus, including checks of the glow plug voltages and the parameters
monitored and used by the on-board computer. Operation and driveability were
deemed typical and acceptable before shipment to SwRI. The GMC bus was
received with approximately 30,400 km (18,900 miles) accumulated.
C. Description of Test Fuel
Both buses were received with on-board tanks full of neat methanol
provided from the bulk supply fuel point at the Golden Gate Transit garage.
Grab samples from both buses were analyzed for methanol, other alcohols, and
water content. Analyses of these two samples are given in Table 5, confirming
that the fuel used was at least a "fuel quality" methanol, and that the higher
alcohols were essentially negligible. The heating value of the fuel methanol
was not determined in this program. For the sake of computing diesel fuel
equivalents, heating values of 19.7 and 42.8 MJ/kg were taken for methanol and
diesel fuel, respectively, yielding a ratio of 2.17 mass units of methanol/mass
unit of diesel fuel for equivalent heat energy. Since both buses were serviced
prior to shipment, no fuels or lubricants were added by SwRI.

D. Test Procedures
Each of the methanol buses was transported to and from California by
way of truck-trailer due to the lack of maintenance support and fuel supply
enroute. Upon arrival, the bus was off-loaded, and a basic operational check
was performed, allowing the driver to become familiar with the controls. The
bus was driven to a public scale for weight determination and returned to the
laboratory for dynamometer set-up.
The chassis testing in this program was based on the test procedure
outlined in EPA's "Recommended Practice for Determining Exhaust Emissions
From Heavy-Duty Vehicles Under Transient Conditions."^) The chassis
dynamometer used in this program was a tandem-axle Clayton heavy-duty
chassis dynamometer modified by the addition of eddy current power absorbers.
Electronic programming of the system enables the use of almost any required
speed-power curve. By utilizing an electrical signal from the vehicle braking
system, electrical braking of the dynamometer rolls is also provided. Each of
the absorption units in tandem has dual rolls that are 8.625 inches in diameter.
Inertia simulation is provided by an appropriate combination of directly-
connected inertia wheels. Maximum inertia simulations readily attainable are
49,000 pounds for single-drive-axle vehicles and 76,000 pounds for tandem-
drive-axle vehicles. Using the programmable dynamometer, the procedure
developed for road load simulation of a vehicle involves establishing the speed-
power curve, determining inertia simulation, and determining system friction.
The equation selected for calculation of the speed-power curve used for
evaluations on the chassis dynamometer is as follows:
RLP = F x 0.67(H - 0.75) W x (V/50p + 0.00125 x LVW x V/50
Where:
RLP = Road Load Power, horsepower
F =1.00 for tractor-trailer and 0.85 for city bus
H = Average maximum height, feet
W = Average maximum width, feet
LVW = Loaded vehicle weight, pounds
V = Velocity, mph
13
-------
The equations used for determination of dynamometer torque and load are as
follows:
Dynamometer torque, foot-pounds = Power, hp x 134.8/Velocity, mph
Dynamometer Load, pounds = Torque x 12/Load Arm, inches
These equations were developed in conjunction with experimental data obtained
with trucks and buses and reported in reference 8.
Once the appropriate inertia wheels were fitted to the dynamometer, the
bus was positioned on the rolls. The rear axle vertical loading was reduced by
blocking up the frame of the bus, and cooling fans were positioned to reduce the
risk of tire damage. With the bus in position, bus exhaust-to-CVS piping was
installed.
With vehicle installation complete the total system absorbed horsepower
was determined using coastdowns. This was accomplished by obtaining
repeatable 88 to 8 kph coastdown speed versus time data and then solving for
the instantaneous decelerations. From the instantaneous decelerations, the
power absorption of the vehicle-dynamometer system was determined as a
function of vehicle speed. The speed-power curve for programming into the
dynamometer controller was then determined by difference between the total
power required on the road (based on previous documentation™') and the power
absorbed by the vehicle-dynamometer system.
Both methanol buses were tested over six chassis cycles or operating
conditions which included steady-state operation at cold idle, 20 kph, 40 kph,
and hot idle; and transient operation over the central business district (CBD)
and bus cycles. All test work was conducted with the air conditioning and all
other accessories turned off.
The cold idle steady-state was conducted with the transmission in neutral
position. Emissions sampling commenced with engine cranking and start of the
engine. The engine was allowed to idle in neutral and emission samples were
taken for 15 minutes. Although it is unlikely that a 15-minute idle in neutral
would occur in field operation, the prolonged idle was used to accumulate
adequate samples for analysis. The term "cold", as it is used in this report,
refers to the engine being allowed to stand overnight in an ambient temperature
between 20 to 30°C (68 to 86°F) prior to and during engine start-up.
After completing cold-idle emissions sampling the bus was operated in a
warm-up mode, then held at 80 kph to check the dynamometer load setting.
Once the load was confirmed, emissions testing proceeded with the 20 kph
steady-state, then the 40 kph steady-state and finally the hot-idle steady-state.
The hot-idle steady-state was conducted with the transmission in drive and the
brakes set. Emission samples were collected over a 15-minute period at each
condition to allow adequate time for sample accumulation.
Emission samples were also taken over the CBD and the bus cycles. The
CBD cycle is one of four transit coach operating profile duty cycles proposed
and used for evaluation of bus fuel economy.^ For this work, the CBD cycle
was composed of 14 repetitions of the basic cycle, which included idle,

acceleration, cruise, and deceleration modes. An example of this basic cycle is
given in Figure 7, and it was repeated 14 times for a chassis driving cycle time
of 580 seconds and a distance of 2.0 miles (3.2 km).

The CVS dilution tunnel is 46 inches in diameter and 57 feet long. This
system has the capacity to obtain three 20 x 20 inch filter samples of
particulate matter along with additional samples needed for analysis of the
total particulate. All testing was conducted with the CVS since particulate
emissions were to be measured over all test conditions.
Extremely low particulate rates were expected, so the CVS dilution tunnel
and the associated sampling systems were cleaned to reduce the potential for
particulate sample interference due to tunnel background particulate. After
cleaning, the CVS and its associated sample systems were operated to verify
low background levels. Propane checks were used to assure that CVS volume
curves were adequate to provide propane recovery within two percent prior to
emissions testing.
Total hydrocarbons were measured over each test cycle by integration of
continuous hydrocarbon monitoring of the CVS-diluted exhaust, and by analysis
of a proportional sample of the CVS-diluted exhaust collected in a bag. For
continuous analysis of total hydrocarbons, the sample was transferred from the
CVS to the Beckman 402 heated flame ionization detector (HFID) by a heated
diesel sample train. Normally, the heated sample train is maintained near
375°F. However, methanol undergoes increased dissociation into H2 and CO at
temperatures above 250°F.(13) To reduce the potential problem with methanol
dissociation, the continuous HC sample train was maintained near 175°F. For
bag determinations, a proportional sample was transferred from the CVS to the
bag by an unheated sample train; then shortly after sampling was completed,
the HC concentration in the bag was determined using a HFID.
Total HC emissions are based on indications from the HFID, which has
been calibrated on propane. However, the HFID response to various species of
alcohols, some individual hydrocarbons, aldehydes, and phenols often differs
from the response to propane. The methanol response of both HFID instruments
used in this program was determined to be 0.80, based on a 90 ppm methanol-in-
air gas standard. The concentrations determined by both HFID instruments
during testing were used in processing the test data on the basis of bag
measurement or continuous measurement. Resultant HC emission levels were
divided by 0.80 to account for the 0.80 response factor of the HFID to
methanol.
Total hydrocarbons are generally assumed to be of the same general
composition as the fuel. In the case of these methanol fueled buses, the total
hydrocarbons are reported on the basis that the "HC" represents methanol.
Therefore, the weight of oxygen is included in the "HC" emissions unless stated
otherwise. Specifically, a HC density of 37.69 g/ft^ was used in the
computation (16.33 g/ft^ is specified in the Federal Register for use of fuels
with a H/C ratio of 1.85) of HC mass from concentration ppmC levels obtained
from analysis by HFID.
Unburned methanol quantities were also determined for both steady-state
and transient chassis operation. CVS dilute exhaust was drawn through a
sample train heated to 79°C (175°F), then through glass bubblers containing
distilled water kept near 2°C in order to condense out and collect unburned
methanol.(13) The jevel of methanol collected was determined by gas
chromatograph using an FID specifically calibrated for quantitative purposes.
16
-------
Although it was assumed that most of the HC measured would be
associated with unburned methanol, an additional proportional bag sample of
CVS-dilute exhaust was obtained for analysis of selected individual
hydrocarbons (IHC). A portion of the gases collected in the bag was injected
into a four-column gas chromatograph using a single FID and dual sampling
valves. The timed sequence selection valves allowed the baseline separation of
air, methane, ethane, ethylene, acetylene, propane, propylene, benzene, and
toluene.' ^
Aldehydes and ketones were determined using the 2,4-
dinitrophenylhydrazine (DNPH) method.'1 3) This method yields individual
species of aldehydes. Dilute exhaust samples were taken from the CVS dilution
tunnel. A heated Teflon sample line and filter were maintained at 190°C
(375°F) (no interference from dissociation of methanol is expected while using
this procedure). The procedure consists of bubbling filtered exhaust gases,
dilute or raw, through glass impinger traps containing a solution of DNPH and
HC1 kept near 0°C. The aldehydes form their respective phenylhydrazone
derivatives (precipitates). These derivatives are removed by filtration, and
subsequently extracted with pentane and evaporated in a vacuum oven. The
remaining dried extract, which contains the phenylhydrazone derivatives, is
dissolved in a specific volume of methanol with anthracene internal standard.
A portion of this dissolved extract is injected into a liquid chromatograph and
analyzed using an ultraviolet detector to separate formaldehyde, acetaldehyde,
acrolein, acetone, propionaldehyde, isobutyraldehyde, methylethylketone,
crotonaldehyde, hexanaldyhyde, and benzaldehyde. The emission rates of these
individual species are then accumulated by computation to yield total aldehyde
emissions.
The transient Federal Test Procedure^12) for heavy-duty diesel engines
specifies that HC emissions be determined from integration of continuous
concentration monitoring of the CVS-diluted exhaust. The procedure provides
the option of determining CO, CO2, and NOX from either dilute sample bags or
integration of continuous concentration monitoring. Carbon monoxide and CO2
levels were determined from proportional dilute exhaust bag samples.
Concentrations of both gases were determined by non-dispersive infrared
(NDIR) instruments. NOX emissions were determined from both integration of
continuous concentration monitoring of the CVS-diluted exhaust and bag
samples, by use of a chemiluminescence (CL) instrument. NOX correction
factors for intake humidity were applied as specified in the 1984 transient
Emission levels for HC, CO, CO2 and NOX were processed along with CVS
flow parameters and bus operating parameters to compute mass emissions on
the basis of distance and fuel usage. These computations were based on the
equations specified in the Federal Register for exhaust emissions from gasoline
or diesel exhaust.'12' These equations were modified per "Calculation of
Emissions and Fuel Economy when Using Alternate Fuels" (EPA Report No.
460/3-83-009) in order to account for the use of an oxygenated fuel.'*^' Using
these modified equations, fuel consumption was computed on the basis of
carbon balance. The fuel consumption during chassis testing was also measured
using a flow meter (Flo-tron), but this method is experimental and the accuracy
is unknown.

-------
Participate emissions were determined from dilute exhaust samples
utilizing various collection media and apparatus, depending on the analysis to be
performed. Particulate has been defined as any material collected on a
fluorocarbon-coated glass fiber filter at or below a temperature of 51.7°C
(125°F), excluding condensed water. The 51.7°C temperature limit and the
absence of condensed water generally dictate that the raw exhaust be diluted,
irrespective of engine operating mode. On the basis of the 51.7°C temperature
limit, the CVS was run at approximately 3200 SCFM during testing of both
buses.
Total particulate mass samples were collected on 47 mm Pallflex T60A20
fluorocarbon-coated glass fiber filter media, by means of a single-dilution
technique. Gravimetric weight gain, representing collected particulate, was
determined to the nearest microgram after the filter temperature and humidity
were stabilized. This weight gain and CVS flow parameters were used to
calculate the total particulate mass emissions from the bus under test.
Particulate mass rate was determined for each individual test cycle in
triplicate.
Metals and other elements that make up the total particulate were also of
interest, so a sample of total particulate matter was also collected on a 47 mm
Fluoropore filter for the determination of trace elements such as calcium,
aluminum, phosphorus, and sulfur by x-ray fluorescence. This analysis was
conducted at the EPA, ORD laboratories in Research Triangle Park, N.C. using
a Siemens NRS-3 X-ray fluorescence spectrometer.
Diesel particulate generally contains significant quantities of condensed
fuel-like or oil-like hydrocarbon aerosols generated in incomplete combustion
zones. In order to determine to what extent the total bus particuiate contained
these various hydrocarbons, a large particulate-laden filter (20 x 20 inch) was
washed with an organic solvent (methylene chloride) using 500 ml soxhlet
extraction apparatus. The dissolved portion of the "total particulate" carried
off with the methylene chloride solvent has been referred to as the "soluble
organic fraction" (SOF). Since the total particulate emission rates were
expected to be very low, filters to be used for determination of SOF were
allowed to accumulate particulate over three runs of a given cycle.
The boiling point distribution of the SOF from the CBD and the bus cycle
were determined by SwRI's Fuels and Lubricants Research Division using a high-
temperature variation of ASTM-D2887-73. Approximately 50 mg (when
available) of the SOF was dissolved in solvent and an internal standard (Cg to
GU compounds) was added. This sample was then submitted for instrument
analysis of boiling point distribution.
Samples of the crankcase oil were taken from each bus and analyzed for
metals and boiling point distribution. The same procedures used on the
particulate were used on the oil samples.
F. Quality Assurance
All work under this work assignment was conducted in accordance with
the Quality Assurance Project Plan for the EPA Contract No. 68-03-3192
18
-------
submitted July 1983. Results obtained from the various sampling and analysis
techniques were checked and reviewed in order to eliminate potential errors in
raw data, instrument reading, computer processing errors, or computations.
System checks such as propane recovery checks, introduction of standard gases
into instrumentation, and weigh chamber control measures were carried out in
order to provide quality measurements. Unregulated chemistry samples were
processed as carefully as possible during the work-up stages of the procedures,
and standards were processed in order to verify proper operation of liquid and
gas chromatographic instrumentation.
The overall accuracy of the emissions data obtained in this program is
dependent on both the measurement accuracy and the buses being tested.
Measurement accuracies for the various emissions determined in this program
are given in Table 6. Since no reference bus of known emissions exists, overall
accuracy is unknown.

relative to number of requested data points) made during this program is given in
Table 7. The reported data represent an overall completeness greater than 95

emissions were 100 percent complete.

IV. RESULTS
This section describes the results obtained from numerous emission
measurements and sample analyses conducted on the M.A.N. and CMC methanol
buses. It is divided into three parts. The first part describes some of the
pertinent details and the chronology of the accumulated test results. The next
two parts detail accumulated regulated and unregulated emission data,
respectively. Overall emission trends and general remarks are given along with
the results.
A. General Test Notes
In preparation for the methanol bus test work, the CVS dilution tunnel and
its associated particulate sampling systems were cleaned of accumulated diesel
fuel-derived particulate. Propane recovery checks were run in order to assure
that CVS volume curves were within the accuracy limit of ± 2 percent.
Arrangements for bus transport were established.
The M.A.N. SU 240 was received in good condition via a drop-deck trailer.
After familiarization and a check that all spark plug wires were in place, the
driver started the bus according to the start-up procedures outlined in the
instructions (essentially turn on the power to the fuel pumps, wait 5 seconds and
start the engine with the foot throttle depressed). The M.A.N. was driven to a
public scale and weighed (24,470 Ib total). Overall performance of the M.A.N.
methanol bus was good. Switch positions of the brake retarding systems were
confirmed to be in the "OFF" position. The inertia wheels of the dynamometer
were set for a simulation of 12,834 kg (28,300 Ib) representing approximately 25
passengers and a driver. Total road load power at 80 kph (50 mph) was
computed to be 58 kW (78 hp); 31 kW (42 hp) due to air resistance, and 27 kW
(36 hp) due to rolling resistance. The dynamometer controls were adjusted to
approximate the computed road load curve of the bus. The exhaust was routed
to the CVS and the bus was operated over segments of the various test cycles in
order to determine the CVS flow-rate required for single-dilution particulate
emission determinations. A surprisingly low CVS flowrate of 3200 SCFM was
adequate for single dilution of the M.A.N. exhaust. Preliminary runs were used
for range finding and instrument set-up.
The sequence of testing was a cold-start idle in neutral, 20 kph, 40 kph,
hot idle in drive, CBD cycle, then a bus cycle. This test sequence was carried
out repeatedly over three test days. Emission samples for HC, CO, CO2> NOX,
IHC, aldehydes, methanol and total particulate were collected or measured
each day. Small particulate samples for metals and large particulate samples
for SOF were accumulated or "stacked" on a single filter, used over a given
cycle during all three replicates of that cycle. This accumulation was done to
improve the accuracy of the SOF and metals determinations by increasing the
weight-to-tare ratio. A sample of the M.A.N. bus crankcase oil was taken for
analysis of metals and boiling point distribution. Cold-start of the M.A.N.
methanol engine went well, and "good" engine idle quality was observed. Engine
operation was "good" over all operating test conditions. The driver was able to
follow both the CBD and bus cycle transient driving schedules in a satisfactory
manner. After accounting for all emission samples, the M.A.N. bus was
23
-------
released for return shipment by trailer. Computer printouts from emission
tests run on the M.A.N. are given in Appendix A for reference.
The CMC methanol bus was received in good condition and was off-loaded
from the trailer with the assistance of the local transit property (VIA
Metropolitan Transit of San Antonio). After familiarization, the CMC methanol
bus engine was started according to the instructions provided. The starting
procedure basically called for turning on the glow plugs for approximately 1-2
minutes, then engaging the starter. If a false start was encountered, the
sequence was repeated. Once the bus was started, the engine was under the
control of the on-board computer and would not respond to accelerator pedal
movement until after about 2 to 5 minutes. Idle quality was very rough until
the engine oil warmed up. After about 15 minutes of low speed idle, engine idle
quality improved. Initially the improvement in idle quality was not as good as
expected, and it was determined that one of the glow plug connections was
faulty. The warm idle quality improved when all the glow plugs were working
properly.
The bus was weighed at the public scale (28,650 Ib total), then driven back
to the laboratory. Inertia wheels of the dynamometer were set for a simulation
of 14,784 kg (32,600 Ib), representing approximately 25 passengers with a
driver. This setting was 270 kg (600 Ibs) higher than desired on the basis of 21
passengers and 1 driver at 68 kg (150 Ib) each, but it was necessary because the
next available lower increment of inertia would have been much too low. In
addition, using 14,784 kg would simulate the same passenger load as used for
the M.A.N. Total road load power at 80 kph (50 mph) was computed to be 60
kW (80 hp); 29 kW (39 hp) due to air resistance and 31 kW (41 hp) due to rolling
resistance. The dynamometer controls were adjusted to approximate the
computed road load curve of the CMC methanol bus. With exhaust routed to
the CVS, the bus was operated over all of the test cycles. Particulate sample
zone temperatures were sufficiently below the 51.7°C (125°F) limit so that the
CVS flow of 90 SCMM (3200 SCFM) could be used for all emission testing in this
project.
The same test sequence used for the M.A.N. methanol bus was used on the
CMC methanol bus. Preliminary checks of emission levels over the various test
cycles indicated substantial differences between the two buses. Testing for
emissions was carried out over three test days using the same procedures as
used for the M.A.N. bus.
The CMC bus performed reasonably well with the exception of cold idle in
neutral. Cold start-up was accomplished with no problem, and the engine did
not stall. However, the idle quality was very erratic and rough for the initial 3
to 4 minutes, continuing to be rough-to-smooth intermittently until
approximately 13 to 15 minutes from the time of start-up. After the 13- to 15-
minute time mark, the computer control shifted air control and fuel scheduling
such that the idle quality became smoother. Aside from the rough idle during
warm-up, the general performance was regarded as "acceptable" by the driver.
The driver was able to follow both the CBD and bus cycle transient driving
schedules in a satisfactory manner.
24
-------
The CMC bus was equipped with a diagnostic data link (DDL). Some of
the outputs from the DDL reader were recorded during steady-state operation
and are summarized in Table 10. The "pulsewidth" represents the number of
crank angle degrees that the injectors are supplying fuel, and the "beginning of
injection" represents the injection timing in degrees BTDC. "Injector response"
represents the time taken from when the computer control requests the injector
be turned on to when the injector solenoid valve actually closes. In addition,
exhaust temperatures were taken from thermocouples located in the exhaust
manifold port of each cylinder. Examining the individual results indicates that
the engine operated consistently over the three runs made for emissions testing.

aObserved over 3 separate runs
The data in Table 10 indicate some engine control changes made by the
on-board computer to accommodate the four steady-state conditions. From the
"pulsewidth" information, more fuel was injected during the cold-start idle in
neutral than was injected during the hot-idle in drive. From the "beginning of
injection" information, it appears that the timing of the methanol bus engine
was substantially retarded from that reported by Toepel, et al during
development work on the CMC methanol engine.^)
A crankcase oil sample was taken, and after accounting for all the
emission samples, the CMC methanol bus was released for return shipment by
trailer. Computer printouts from emission tests run on the CMC are given in
Appendix B for reference.

B. Regulated Emissions
Regulated emissions of HC, CO, NOX and particulate were determined
over four steady-state conditions and two transient tests or cycles. Results of
three determinations of the regulated emissions over these six test conditions
are given in Tables 11 and 12 for the M.A.N. and the CMC methanol buses,
respectively. Averages of the three determinations are also given, along with
computed and measured fuel consumption and the computed fuel economy
figures. Emissions are tabulated on the basis of grams per unit distance and
grams per unit mass of methanol fuel. In all cases, fuel specific emissions were
calculated on the basis of fuel usage derived from carbon balance calculations
using continuous HC, bag CO, and bag CO2 determinations.
Total hydrocarbons were measured using a HFID calibrated on propane
and having a response of 80 percent to methanol. "As-measured" hydrocarbon
emissions were increased to account for the reduced response of the HFID
instrument to methanol. In addition, hydrocarbon mass emissions reported here
were computed using a density of 37.69 g/ft* for methanol with a H/C ratio of
4.0 (versus 16.33 g/ft^ for fuel with a HC ratio of 1.85), so the weight of oxygen
contained in the methanol molecule is included in the mass HC emissions
reported. Hydrocarbon values were determined by both bag and continuous
measurement techniques. Bag techniques are generally used with spark-ignited
engines (gasoline) and continuous techniques are generally associated with
compression ignition engine emissions (diesel). Generally, both techniques are
applicable to these methanol fueled vehicles, and both techniques usually gave
comparable information. The precision (or percent variation) values for both
HC and other emissions are given in Tables 8 and 9 of the Quality Assurance
section of this report.
Emissions of NOX were also determined on the basis of bag and continuous
techniques. Continuous NOX measurements indicated lower emissions of NOX
than bag measurements which is opposite the trend usually noted for diesel NOX
emissions measurements. Extensive checks of the span gases, instrument
calibrations, integrators, bag cart instruments, and data processing were made
but higher NOX levels from bag readings than from continuous readings could
not be explained. The difference may be attributed to the fact that NOX
concentrations using a single dilution CVS were low relative to background
levels. Carbon monoxide and carbon dioxide emissions were determined from
proportional bag samples only.
Concentrations of HC and CO were very low (near background levels) for
the M.A.N., making it difficult to accurately determine hydrocarbon emissions.
To the other extreme, concentrations of HC and CO were very high for the
CMC. Particulate emissions were based on filter weight gain. Particulate
collection levels were very low for the M.A.N., and the ability to determine
very small weight gains make it difficult to establish accurate particulate
emissions.
On the basis of these qualifying remarks the emissions data have been
reported in the Tables to three significant figures or limited to two places to
the right of the decimal, with the exception of three decimal places on the
particulate emissions from the M.A.N.. Similarly, fuel consumption by carbon

balance and test distance were used to compute fuel economy, which is
reported to four significant figures to allow more complete conversion of
emissions from one set of units to another. Computer printouts from all the
gaseous emission tests compiled in Tables 11 and 12 are given in Appendices A
and B for the M.A.N. and the CMC methanol buses, respectively. A summary
of the averages from Tables 11 and 12 is given in Table 13.

Cold idle emissions included engine start-up and low-speed idle operation
with the transmission in neutral for a total of 15 minutes. The engine was not
speeded up or operated at fast idle, and no attempt to cause a fast warm-up
was made. For both buses HC levels were relatively high for a short-time (1-3
minutes) after start-up, then tapered off and stabilized. On the basis of HC
levels obtained over other operating conditions of the M.A.N., it appears that
the catalyst was not functioning during the cold idle. Even so, cold idle
emission levels of HC, CO, and particulate from the M.A.N. were significantly
lower than for the CMC bus.
31
-------
Examining the continuous HC trace from the CMC during cold idle, HC
was very high during the initial 2 to 5 minutes after engine start, when the
engine idled very roughly. The HC level began tapering down to about half the
initial peak level, and it held stable for the remainder of 13 to 15 minutes,
coinciding with improved but still somewhat erratic idle quality. After 13 to 15
minutes the idle quality smoothed and the HC level dropped again. These
changes in HC levels were noted to correspond with changes in engine operation
controlled by the on-board computer modifying fuel scheduling, scavenging air
throttling, and engine rpm. The high levels of HC emitted by the CMC (6 times
those from the M.A.N.) during the cold idle represent a significant portion
(about 20 percent) of the fuel consumed. In addition, very low emissions of NOX
from the CMC during cold idle operation were likely due to poor combustion.
Cold idle particulate emissions for the M.A.N. were very low. Cold idle
particulate levels for the CMC were low compared to a diesel powered bus, but
not near the low levels expected of an engine that consumes neat methanol. It
is likely that engine lubricating oil was scavenged out into the exhaust and
caused the higher-than-anticipated particulate emissions. After completing
cold idle emissions testing, the buses were operated for 5 to 10 minutes at
speeds from 20 to 50 kph in order to fully warm up the engines for the
remaining tests.
Emission results from warm engine testing of the M.A.N. and CMC were
significantly different from cold idle testing. Hydrocarbon emission levels from
warm engine testing of the M.A.N. were very low at about 1 g/kg fuel, or less
than 1 g/km. Carbon monoxide emissions were essentially negligible. Low
levels of both HC and CO indicate that the engine/catalyst package was
working well. It should be noted that emissions during the hot idle in "drive"
were stable, and indicated the catalyst continued to steadily function for a
relatively long idle period. Emissions of NOX from the M.A.N. over all test
operation ranged from 4.8 to 11 g/kg fuel, or 3.3 to 8.8 g/km. These levels
were in the same range as noted for the M.A.N. D2566 FMUH methanol engine
tested on behalf of EPA by SwRI in 1982. Particulate emissions from the
M.A.N. over all test operation were very low, ranging from 0.05 to 0.11 g/kg
fuel, or 0.02 to 0.06 g/km. These particulate levels compare well to the 0.08
g/kg fuel obtained during engine dynamometer transient testing of the M.A.N.
engine in 1982.'5'
Fuel economy of the M.A.N. ranged from 1.01 to 2.33 km/kg of methanol.
The M.A.N. bus has been road tested for fuel economy as reported in Reference
3 by 3ackson, et al. Jackson reported fuel economy values of 10.17 and 4.56
miles per equivalent diesel gallon for the M.A.N. methanol bus for 40 kph (25
mph) steady-state and CBD operation, respectively. These values, convert to
2.36 and 1.06 km/kg of methanol, agreeing well with values of 2.33 and 1.01
km/kg of methanol determined for 40 kph steady-state and CBD operation on
the dynamometer in this program.
Hydrocarbon emission levels from warm engine testing of the CMC
methanol bus were very high compared to the M.A.N. The CMC methanol bus
does not utilize a catalyst for exhaust aftertreatment. HC emissions for the
CMC appear to be influenced by load on the engine. The light load conditions
of cold idle, 20 kph, and 40 kph all had notably higher levels of HC than the hot
32
-------
idle in "drive", bus cycle or CBD cycle. Considering that the HC emissions are
unburned methanol, the emission levels given in Table 12 represent about 6
percent of the fuel during transient operation, and 10 to 23 percent of the fuel
during some steady-state modes. Carbon monoxide from warm engine operation
of the CMC methanol bus ranged from 37 to 51 g/kg fuel. Warm engine
emissions of NOX were extremely low for the CMC bus, and ranging from 0.6
to 3.7 g/kg fuel. Lower NOX emissions is one of the claimed benefits for using
methanol. However, low NOX emissions can also be indicative of poor
combustion quality.
Particulate emission from the CMC methanol bus were low, ranging from
0.25 to 0.69 g/kg of methanol. The cold idle, hot idle and CBD had higher
particulate emission levels than the 20 kph, 40 kph, and bus cycle operations.
Engine oil is assumed to account for the majority of these particulate
emissions. Particulate sample filters appeared to have a slight gray tint after
use with the CMC methanol bus.
Characteristics of this two-stroke engine allow a certain amount of
engine oil to be scavanged out into the exhaust. During prolonged idle, oil can
accumulate in the air box. Much of this oil accumulation is emitted during
moderate to hard accelerations as condensible hydrocarbons, which can be
collected as total particulate and often are included as part of the soluble
organic fraction (SOF). The CBD cycle alternately calls for idle, then
acceleration to 32 kph (20 mph). The bus cycle contains much idle and few
accelerations during the early portions of the test, but little idle and many
accelerations in the latter portion. The differences between these two
transient cycles may explain the higher particulate emissions for the CBD than
for the bus cycle.
Visible smoke was not measured during this program mainly because no
smoke emissions were expected. However, in observing the CMC methanol bus
enroute to the loading point, low levels of visible smoke were noticed. The
smoke levels were judged to be near 5 percent opacity, and were noted for a
brief time (1 to 2 seconds) whenever the bus accelerated from a stop. No other
visible smoke was noted from either methanol bus.
Fuel consumption of the CMC methanol bus was greater than for the
M.A.N. over all the conditions tested, especially at the cold idle condition,
which appears to utilize a fuel enrichment mode. Jackson, et. al^' reported a
fuel economy of 8.17 and 3.22 miles per equivalent diesel gallon for the CMC
methanol bus operated over the road at 40 kph and on the CBD cycle,
respectively. These values, convert to 1.90 and 0.75 km/kg of methanol,
comparing fairly well to 1.48 and 0.71 km/kg of methanol measured in this
program for corresponding operation on the dynamometer. Values for the CMC
bus reported in Reference 3 were obtained in December of 1983. Since that
time, the CMC methanol bus has undergone several engine/control
modifications along with mileage accumulation.
C. Unregulated Emissions
The other emissions measured in this program are currently considered
unregulated emissions and include unburned methanol, aldehydes, selected
33
-------
individual hydrocarbons, and the soluble organic fraction (SOF) of the total
particulate. Selected samples of the total particulate were analyzed for
elemental content and the boiling point distribution of the soluble organic
fraction (SOF) of the total particulate was determined. Analyses for elemental
content and boiling point distribution of the crankcase oil from both buses were
also conducted for comparison to the characteristics of the total particulate
and its soluble fraction.
Results from determinations of unburned methanol emissions from both
buses over the six operating conditions are given in Table 1*. Unburned
methanol emissions essentially are the hydrocarbon emissions for the methanol
fueled buses. If unburned methanol emissions, given in Table 14, are multiplied
by 0.8, (based on the response of FID to methanol) the resulting levels compare
quite well to those reported as HC emissions in Table 13. Similarly, the points
discussed for the HC emissions apply to the unburned methanol emissions. Over
the cold-start idle, both buses have high unburned methanol emissions relative
to their emissions over the warm engine operating modes. The highest average
level of unburned methanol emitted for the M.A.N. was 33,000 mg/kg of
methanol, representing 3.3 percent of the fuel consumed. Over the warm
engine operating conditions of the M.A.N., where the catalyst was known to be
working, the levels were substantially lower. For the CMC, the highest level of
210,000 mg/kg of fuel (or 0.21 kg/kg of fuel) was found over the cold idle
condition representing 21 percent of the fuel consumed. Levels of 4.4 to 5.8
percent of the fuel supplied were emitted by the CMC over the hot idle, CBD
and bus cycle operation. About 17 percent of the fuel supplied was emitted
during the 20 and 40 kph cruise conditions.
Other hydrocarbon emissions were measured as individual hydrocarbons,
described in the analytical procedure section of this report. Results from these
determinations are given in Tables 15 and 16 for the M.A.N. and CMC methanol
buses, respectively. For the M.A.N., methane was the predominant individual
hydrocarbon emitted; and it was greatest during the cold-idle. Methane was
also noted to a lesser extent over the CBD, 20 kph and bus cycle operations,
Small concentrations of ethane were noted along with an indication that
ethylene and propane may be present over some conditions.
For the CMC, methane was also the predominant individual hydrocarbon
found. Methane emissions were greatest during the bus and CBD cycles. Levels
of methane were all near 100 mg/kg for the other test conditions, even the cold
idle. A greater variety of selected individual hydrocarbons, including ethylene,
ethane and toluene, were noted for the CMC. These more complex species,
relative to methane, may be associated with crankcase oils entering into the
combustion process with the neat methanol. Ethylene emissions for the CMC
over the six test conditions averaged about 46 mg/kg fuel with the highest
levels noted for the hot idle and the CBD. Lesser levels of ethane, propane,
propylene, benzene, and toluene were found, but the variabilities for those
determinations were relatively high, indicating only that these species may be
present over some conditions.
Individual aldehydes were determined using the DNPH procedure. Tables
17 and 18 summarize the individual aldehyde emissions for the M.A.N. and the
CMC methanol buses, respectively. "Total aldehydes" were obtained by adding

the levels determined for the individual aldehydes. Formaldehyde was the
predominant individual aldehyde emission for both the M.A.N. and the CMC
buses, essentially representing the "total aldehydes", especially in the case of
the M.A.N. bus. Some low levels of acetone emissions were noted during
testing of the M.A.N. For the M.A.N., cold idle produced the highest average
emission of 2000 mg formaldehyde/kg of fuel. With warm engine/catalyst, the
levels of total aldehydes ranged from 200 to 92 mg/kg fuel over all other test
operation for the M.A.N.
For the CMC, hot idle produced the highest average emission of 3400 mg
formaldehyde/kg of fuel. Formaldehyde and the "total aldehydes" emission
levels were greatest for the CMC at hot idle operation, followed by lesser
amounts for the 20 kph, cold-idle, 40 kph, then transient operation.
Acetaldehyde was noted along with lesser levels of acetone, benzaldehyde, and
isobutyraldehyde and MEK as a group. A few other species of aldehydes and
acrolein were noted, but the variability of their determination was very high.
The greater number of species noted for the CMC methanol bus is likely
attributed to engine crankcase oil entering into combustion.
Large 20x20 inch filters were used to collect samples of total particulate
for extraction of the soluble organic fraction (SOF) of the total particulate with
methylene chloride. In all cases, a given filter was used over all three replicate
runs of a given cycle or steady-state condition. Since particulate emissions
from both buses were minimal, the background contribution to SOF from
several blank filters were determined. SOF emission results were corrected for
this background contribution. The resulting SOF levels for both buses are given
in Table 19. For the M.A.N., the SOF portion of the total particulate accounted

for essentially all of the particulate emissions during the cold idle condition.
For warm engine/catalyst operation of the M.A.N., the SOF ranged from about
10 to 50 percent of the total particulate. These soluble percentages coupled
with low total particulate levels yield very low fuel specific emissions of SOF.
For the CMC with no catalyst aftertreatment, the soluble portion of the total
particulate ranged from 80 to 90 percent over all test operation.
High temperature boiling point distributions of the SOF and oil samples
from both buses were obtained, using an internal standard for quantitative
purposes. The boiling point distribution of the SOF from the CBD and bus cycle
particulate along with that of the crankcase oil for the M.A.N. are given in
Figures 9, 10 and 11, respectively. Corresponding boiling point distributions
for the CMC bus are given in Figures 12, 13, and 1*. The retention times are
shown on the horizontal axis in minutes and correspond to programmed
temperature simulation. The peaks shown before 15 minutes retention time
represent the presence of the internal standard. Peak heights shown in the
figures have been normalized and are of no quantitative value, except for data
storage and manipulation for graphics.
Chromatograms of SOF from CBD and bus cycle operation of the M.A.N.
(Figures 9 and 10) appear to be very similar in characteristic shape with the
maximum distillation rate occurring at about 26 minutes, coincident with
retention times of C$2 to C^ normal paraffins. In addition, both
chromatograms have similarities between 20 and 24 minutes (coincident with
retention times of hydrocarbons from C20 to ^g)- ^e M'^'Nt er>gine °il
chromatogram (Figure 11) has a single maximum between 24 and 30 minutes,
about the same as retention .times of C2g to C^Q hydrocarbons. The maximum
for the oil sample occurs at 26 minutes, the same as noted for the SOF. It is
likely that there would be even more similarity of chromatograms, but the
M.A.N. catalyst probably breaks down some of the long chain oil molecules,
causing the lower-boiling material found in the SOF from the M.A.N.
Chromatograms of SOF from CBD and bus cycle operation of the CMC
(Figures 12 and 13) are essentially identical, and both are very similar to the
chromatogram of the CMC lube oil (Figure 14). For all three samples, the
retention times of the materials ranged from 21 to 28 minutes, coincident with
those of normal paraffins C2Q to C^Q. The maximum distillation rates of all
three chromatograms appear at approximately 25 minutes, about the same as
for a C3Q molecule. Based on these similarities, the SOF from the CMC
methanol bus appears to be mostly engine oil.
Elemental analyses of the total particulate from selected test conditions
and crankcase oil of both buses were performed by EPA-RTP. Results from
these analyses are given in Table 20 for the M.A.N. and in Table 21 for the
CMC.
Crankcase oil samples from the two buses contained similar levels of Ca,
Cu, Cr, and Fe. Oil from the CMC bus contained measurable levels of Cl and
Mg; whereas, the M.A.N. oil did not. The oil from the M.A.N. contained lower
levels of P and Zn than noted for CMC oil, but it contained about 1.7 times the
S level.

Total particulate from the M.A.N. contained 3 to 4 percent Fe with lesser
quantities of Ca, Cu, and S. Total particulate from the CMC generally
contained 1 to 2 percent Fe with lesser quantities of Ca, P, and Zn. The
greatest concentrations of these elements for the CMC were noted over the
hot-idle condition, followed by lesser concentrations noted over bus cycle, CBD,
and the 40 kph conditions. Concentrations of various elements in the
particulate from the M.A.N. were mixed over the various conditions tested.

SAE Technical Paper No. 860305 "Emissions from Two Methanol-
Powered Buses"
16. ABSTRACT
Exhaust emissions from the two methanol-powered buses used in the California Methanol
Bus Demonstration have been characterized. The M.A.N. SU 240 bus is powered by
M.A.N.'s D2566 FMUH methanol engine, and utilizes catalytic exhaust aftertreatment.
The CMC RTS II 04 bus is powered by a first-generation DDAD 6V-92TA methanol engine
without exhaust aftertreatment. Emissions of HC, CO, NOX, unburned methanol,
aldehydes, total particulates, and soluble fraction of particulate were determined
for both buses over steady-state and transient chassis dynamometer test cycles.
Emission levels from the M.A.N. bus were considerably lower than those from the
CMC bus, with the exception of NOX. Comparison of emission levels from methanol-
and diesel-powered buses indicates that substantial reduction in emissions
(especially particulate and NOX) are possible with careful implementation of
methanol fueling.
