The author, Mr. Karl J. Springer, -was the Project Leader of the re-
search and development work. This project, authorized by Modification
No. 2 to EHS 70-113, began in February, 1972, and was completed in
February 1973.
The principal engineers associated with this project were Mr.
Clifford D. Tyree, responsible for the initial road studies, and Mr. Melvin
Ingalls, who supervised the laboratory test group vehicle tests and com-
pleted the road studies.
The Project Officer cognizant of this project was originally Mr.
Charles Domke, Chief, Surveillance and Inspection Branch, Division
of Motor Vehicle Pollution Control, Air Pollution Control Office, Environ-
mental Protection Agency, 2565 Plymouth Road, Ann Arbor, Michigan
48105. Mr. John White of the same office assumed the Project Officer
responsibility about midway through the project. This project was identified
within Southwest Research Institute as No. 11-2862-01.
This is Part I of a long term study of emission behavior of gasoline
trucks above 6,000-lb gross vehicle weight. Part II final report is scheduled
for April 1974 and will cover the 30 month surveillance test results of a
fleet of 145 trucks.

ABSTRACT
This report describes the results of mass emissions tests
of a number of gasoline powered trucks above 6,000-lb GVW during
road driving and chassis dynamometer operation. A constant volume
sampler was used to obtain samples during operation on a 7. 24 mile
course in San Antonio and during the entire 20 minute nine-mode FTP.
The agreement between the road and dynamometer results, in terms of
grams of emission per pound of fuel, was used to determine what road
emissions would be from a larger, 145 vehicle, fleet that was subjected
to similar CVS nine-mode FTP tests in the laboratory. Consideration
of the end use of the data was made with preliminary expressions de-
veloped for possible use in determining the contribution of gasoline
HDVs to air pollution. In so doing, the objective of this work, to pro-
vide data that will assist the EPA to better estimate national impact from
this source, has been achieved. A group of 25 trucks representing a
variety of makes, displacements and gross vehicle weights were studied
and extensive road and dynamometer hydrocarbon, carbon monoxide and
oxides of nitrogen emission data are included in this report. Also included
are percent of time at various increments of engine speed and manifold
vacuum and vehicle speed that define how each truck operated in traffic
over the road course.

I. INTRODUCTION
According to the latest statistical information(l)*, all trucks
comprise about 16. 6 percent (1 7, 871, 000) of the total vehicles registered
and burn approximately 28. 2 percent of the gasoline consumed in the United
States. From sales dataU), approximately 42 percent of the trucks and
buses sold are above 6, 000-lb gross vehicle weight (GVW). This estimate
includes diesel vehicles which are a relatively small number. Though
there is less knowledge regarding the role of the gasoline-powered engine
in heavy-duty vehicle (HDV) operation than say light-duty (cars), the EPA,
formerly the National Air Pollution Control Administration (NAPCA), has
sponsored a continuing long-range activity at Southwest Research Institute.
A . Previous Projects
Southwest Research Institute's Emissions Research Laboratory has
been privileged to have conducted a major portion of the research with
HDVs beginning in June 1967. Past efforts included acquisition of baseline
emissions data from 150 gasoline and LPG fueled spark-ignited engine-
powered trucks and buses using three experimental road-like chassis
dynamometer procedures. To acquire the emissions, a special truck
version of the constant volume sampler (CVS) was used which permitted
expression of contaminants on a mass basis. The results of the survey
are contained in the SwRI final report(2) which concluded that the three
proposed experimental nonconstant speed cycles were not recommended
for use in testing emissions from heavy-duty vehicles powered by spark-
ignited engines. The findings of these earlier studies -were summarized in
AIChE. and SAE papers'-^' "*' which described the preparations and baseline
data results, respectively.
The second major work in this continuing program compared road
route hydrocarbon (HC), carbon monoxide (CO), and nitric oxide (NO) emis-
sions to chassis dynamometer by the Federal nine-mode constant speed
cycle (FTP) for six trucks of various sizes and makes. Using a CVS, the
current Federal cycle was subjected to a number of modifications to
investigate what improvements might be made to make the Federal procedure
agree more with road operation(S).
The third in this series of projects, sponsored by the Environmental
Protection Agency, was completed in April, 1972. The first of the three-
phase project was a broad emission characterization study of four 1969
trucks under a wide variety of engine speeds, power levels, and both
stationary and chassis-operated engines. Emission rates of hydrocarbons,
carbon monoxide, and nitric oxide were expressed in mass units of grams
per minute, per pound of fuel and per bhp-hr. In addition to the steady-state
*Super script numbers in parentheses refer to the List of References at
the end of this report.
-------
emission maps, a number of transient accelerations and decelerations were
studied using a variety of simulated vehicle inertias. The second phase was
a four-vehicle study of the effect of four different road routes on emission
rates. The road routes were sufficiently different to be distinct, yet were
considered representative of actual truck driving. The final phase was a
nine-truck evaluation of an experimental 23-mode test procedure using
both stationary and chassis-operated engines. The three phases of this
project generated a large body of data that is summarized in the report^")
and included in some detail in a number of appendixes.
The precedent for the operation of trucks on a road route and on a
closed nine-mode FTP using CVS for mass emission measurement was
established in an earlier project completed in July, 1970'5). This effort
utilizes the equipment, instrumentation, route, and approach of this
earlier project and in a sense is a continuation.
B. Project Reviews
A project review conference was held on February 14 and 15, 1972, at
the Emissions Research Laboratory of SwRI. Personnel in attendance from
the EPA were Messrs. Charles Domke and Jim Marzen of the Division of
Motor Vehicle Pollution Control and Messrs. Jim Hammerle and David
K?rcher of the Division of Air Quality and Emission Data. Mr. Karl Springer,
Manager of the Emissions Research Laboratory hosted the meeting assisted
by members of the Emissions Research Laboratory professional staff,
including Messrs. John Storment, Clifford Tyree, and Melvin Ingalls.
The project work and results to that date were reviewed and procedures
for the work required in the recent contract revision were discussed. Specific
items covered included:
1. A decision to investigate a detailed analysis of surveillance
emission data on a percent change in emission level versus
mileage basis to ascertain cost and effectiveness of the
analysis.
2. A decision to use the 1975 light duty CVS calculation pro-
cedures, with the exception of the humidity correction
factor for NOX.
3. Frequency of the propane calibration of the CVS was discussed.
It is planned to check the CVS calibration a minimum of once
a week.
The equipment and procedures used for the chassis version of the
Federal 9-mode heavy duty test procedure were observed during an actual
surveillance test. Both the continuous sampling equipment and the CVS
-------
were demonstrated. The road route test procedures were explained and
an actual road route run was observed.
Mr. Tom Bejma of the Surveillance and Inspection Branch,
Division of Motor Vehicle Pollution Control, Environmental Protection
Agency, visited the Emissions Laboratory on June 13 and 14, 1972, to
review the project, check test and calibration procedures, and discuss
EPA recommendations and requirements for instrumentation calibrations.
It is our understanding that the procedures for both truck testing instru-
mentation and calibration were satisfactory. Several recommendations
were made for improvements in instrumentation calibration procedures
which were implemented.
Messrs. John White and Tom Bejma, of the Surveillance and
Inspection Branch, Division of Motor Vehicle Pollution Control, EPA,
also visited the Emissions Research Laboratory at SwRI on August 8 and
9, 1972. The history and current status of the project was reviewed for
Mr. White, who has been designated as Project Officer for Contract
EHS. 70-113, effective August 4, 1972. Messrs. White and Bejma witnessed
the monthly calibration of the Beckman instrumentation system used for the
nine-mode FTP and the analytical instrument train used for reading bagged
samples from the constant volume sampler (CVS). The heavy-duty vehicle
CVS was also calibrated at this time. A vehicle test utilizing the chassis
version of the nine-mode heavy-duty FTP was also witnessed. The visit
concluded with a drive over the road route course to familiarize the new
Project Officer with the San Antonio Road Route.
-------
II. OBJECTIVE AND APPROACH
The main objective of this project was to determine mass emission
rates for use in estimating national impact from gasoline powered HDVs.
The project was designed to generate basic data of tailpipe emissions on
a mass basis over a road course and during the nine-mode FTP using a
CVS. Two groups of vehicles were involved.
A. Road Group
This group consists of 25 1970 or later model vehicles, each
studied over a two week period to:
(1) Determine the HC, CO and NOX emission rates during
road operation.
(2) Define truck road operation in terms of percent time in
various engine speeds, vehicle speeds, and engine mani-
fold vacuums, etc.,
(3) Determine the HC, CO and NOX emission rates during
chassis dynamometer operation by the nine-mode FTP
(concentration) and closed CVS nine-mode FTP (mass)
methods, and
(4) Examine the effect of "cold" versus the usual "warm"
or "hot" start procedure on emission rates in terms of
concentration (standard FTP) and closed nine-mode CVS.
B. Laboratory Group
This group involved the 145 1970 and 1971 vehicles in the sur-
veillance fleet that is currently in operation to determine emissions per-
formance from control equipped engines over a 30 month (approximately
50,000 mile) period.
Simultaneous concentration and mass emission measurements were
obtained during a nine-mode test using the FTP and the closed CVS procedure.
The objective of these tests (Fourth Round) was to obtain mass emissions on
a larger body of vehicles than the road group. Also, the surveillance vehicles
represented a greater variety of operation, application, and range of dis-
placements than the road group.
C. Utilization of the Results
By relating the Road Group road-to-chassis results from CVS in terms
of grams per pound of fuel (g/lb fuel), a factor can then be applied to the
-------
Laboratory Group CVS chassis nine-mode results to estimate their road
emissions. These rates, in g/lb fuel, can then be used in determining
overall mass emissions from gasoline trucks by multiplying by fuel con-
sumption in gallons per year. An alternative is to multiply by total
miles and dividing by fuel consumption rate in miles per gallon. Assuming
production statistics are available by engine displacement, the emission
rates per different categories of vehicles can be utilized to estimate national
impact. Though the latter is the ultimate purpose of this project, the SwRI
efforts were limited to development of basic data and determining the road
to FTP dynamometer factor and its application to the Laboratory Group results.
National impact estimation will be made by EPA's Office of Air Programs,
Applied Technology Division, Air Quality Management Branch, Research
Triangle Park, North Carolina.

III. EQUIPMENT, INSTRUMENTS, VEHICLES, ROAD ROUTE,
PREPARATIONS AND PROCEDURES
This section contains a brief description of the instruments, equipment
and facilities, road course, preparations and procedures used to conduct this
project.
A. Exhaust Sampling and Analysis
Two basic types of exhaust sampling techniques were used during this
program. The most familiar set of instruments used was the nondispersive
infrared (NDIR) sampling train for raw exhaust gases specified in the Federal
Register(7) for the nine-mode cycle (FTP). This system is described first.
Another technique used was the constant volume sampler (CVS) for diluted
exhaust gases and the related analyzers.
(1) Nine Mode Continuous Sampling, Analysis, and Instrumentation
The exhaust gas sampling and analysis for the nine-mode cycle or FTP
was with a system similar to that shown in Figure 1. The system meets the
requirements,,and specifications established in the Federal regulations!?)
for heavy-duty vehicle exhaust sampling. A component description of the
system is detailed in the above referenced Federal regulations. Nominal
full-scale concentration levels for the five NDIR analyzers are as follows:
V
(1) Low-Range HC - 1000 ppm hexane
(2f High-Range HC - 10, 000 ppm hexane
(3) CO - 11 percent
(4) ' COz - 16 percent
(5) NO - 4000 ppm
Although nitric oxide was not included in the then current Federal regulations
relating to g°asoline HDV's, this contaminant was important from a research
standpoint.
s> ^
The output of each analyzer was fed to strip-chart recorders. The con-
centrations from each trace •were then obtained from the continuous traces by
0 ' "
hand as specified in the nine-mode FTP. The average concentrations were
then transferred to computer cards for further processing to obtain composite
values for HC, CO, and NO. This method was used as a back-up to the
real time computer system normally used. The computer system shown to
the right of the NDIR cart in Figure 1 was designed and assembled by SwRl.
This computer utilizes a Data General Super Nova, 8K central processor,
and a Computer Products Series RTP 7410 multiplex. The computer program
was also prepared by Institute personnel. This computer system was very
helpful during this program to determine nine-mode FTP results immediately
after completion of the tests. The reliability and repeatability of the on-line
-------

FIGURE 1. CONTINUOUS NDIR SAMPLING/ANALYSIS/COMPUTER SYSTEM

-------
computer has been shown to be equal or better than manual chart reading
and computer reduction of data.
The NDIR cart was subjected to a rigorous calibration according to
exacting EPA requirements. Both static and dynamic gas simulator tests
were run initially on this and a similar back-up cart by Mr. Matt Macocha
of EPA during the period of September-November, 1971. Recheck of
calibrations and instrument response was accomplished periodically during
the course of this project by EPA. More frequent calibrations of all NDIR
and FIA instruments were made to assure optimum accuracy. One of the
EPA checks was to name an unknown to ± 1 percent, a difficult requirement
since the basic detector is only specified to ±1 percent by the manufacturer.
Suffice to say that no tests were made until initial calibrations were
satisfactorily completed and an EPA acceptance of time response obtained.
(2) Constant Volume Sampler and Analytical Equipment
This sampling system was an EPA development using the integrated
plastic (Tedlar) bag collection technique. The sampler has a nominal flow
rate of 600 cubic feet per minute (cfm). The mixture of diluent air plus
exhaust gas making up the total flow is cooled in a two-pass stainless steel
air-to-air heat exchanger. This sampler is an enlarged version of the
original EPA prototype automotive CVS. It was built and calibrated in a
previous project and described in an earlier final report'*-). Figure 2 is a
schematic of the truck-size CVS. Improvements made in the CVS prior to
this project were to incorporate the latest type of diluent air filters as
specified in the Federal regulations for the passenger car, light-duty CVS.
- Calibration of the CVS was originally accomplished using an orifice
plate made according to the specifications of the American Society of
Mechanical Engineers Flow Section Handbook as the primary element. With
a Meriam Micro-Manometer to measure the change in pressure in 0.001 in.
of water increments, the flow was calculated. Temperature and pressure
were measured at inlet conditions to the positive displacement blower, and
the airflow measured at the upstream orifice plate was plotted against inlet
conditions. Recent calibration of the airflow has been made using a Meriam
Laminar Flow element with calibration traceable to the National Bureau of
Standards.
The CVS was used during dynamometer and road evaluation procedures.
The only differences in the operation of the CVS was the power source. For
road evaluation, a 25-kw trailer-mounted generator set was used to provide
power for the CVS and related test equipment. Figures 3-5 are typical
photographs of the CVS mounted in the bed of a truck prepared for road
route evaluation. Note the CVS is carried onboard the truck and the 25-kw
generator is pulled behind the truck.

magnetic tape, providing 48 recordings or data points per second.
The strip-chart recorders and transducer equipment was operated by
a technician who rode in the van and also operated the CVS. The Metrodata
portable magnetic tape data recorder was also located in the van adjacent to
the CVS operator. Fuel container and three-way valve remained in the
truck cab. Figure 7 shows the Metrodata equipment and tape deck.
The road manifold vacuum, engine rpm, vehicle speed, throttle posi-
tion (open-closed), and transmission gear position data, recorded on the
seven track 0. 5 inch magnetic tape, was computer reduced using a suitable,
slightly modified "canned" program. In order to define the truck's operation,
percent of time at various increments of manifold vacuum, engine rpm, and
vehicle speed as well as gear position were the computer outputs. Although
several runs were recorded, only one or two such test runs per truck were
subjected to complete computer analysis.
B. Chassis Dynamometer
The SwRI chassis dynamometer system used in this and previous projects
was a'modified Clayton CT-200 series dynamometer. Up to 200 hp may be
absorbed with this water brake-type of absorber. This system incorporates
a 50-hp, three phase, AC electric motor that, when engaged, will maintain
a constant rear wheel speed during power and closed throttle (CT) operation.
The electric motor is coupled to the front roll of the chassis dynamometer
with a positive drive belt. The vehicle engine speed can be changed by
changing vehicle rear wheel speeds either by operating in a different trans-
mission drive gear or changing motor drive pulleys.
Figure 8 shows typical views of trucks being evaluated in this facility.
The top photograph is a side view of a truck mounted on the dynamometer
rolls. In the foreground is the CVS dilution air filter housing containing
the prescribed particulate and activated charcoal filters for cleanup of the
diluent. Note the stainless steel exhaust pipe located on the floor connecting
the engine exhaust to an offset Tee below the filter plenum. The bottom
photograph shows a truck prepared for test by the CVS which is. located to
the left and rear of the truck.
C. Vehicles-Engines Tested
The test vehicles-engines were in two groups. None of the vehicles were
selected on the basis of their emission rates, etc. , but rather reflect a
randomly obtained sample of in-service units.

14
-------
This group of 25 trucks included 17 vans, two stake body trucks
and six truck tractors ranging in GVW from 10, 000 to 32, 500 Ibs. The
six tractors have GVW's from 24,000 to 32, 500 Ibs. that do not include
the trailer which would normally be single axle,or on occasion, tandem.
Depending on tire size, number of axles and state regulations, the gross
combined weight, GCW, of a tractor trailer could go to 64, 000 though
this load would not normally be incurred except in commodity hauling of
liquids or in the steel or construction trades. For the bulk of intra-city
use, trucks operate only partially loaded and normally are able to stay
up with traffic. The engine displacement ranged from 300 to 478 cubic
inches representing six makes and a total of 13 different displacements.
One drawback to this project and previous projects of this type is
the difficulty of obtaining trucks from private operators for a two week
outage period. In most all cases, it is not possible to use such vehicles
even where rental vehicles are offered because of distinctive truck mark-
ings, special bodies, locking arrangements, licensing and insurance.
Trucks 7, 10, 11, 21, 23, 24 and 25 were obtained from non-rental
sources. In two instances, trucks 3 and 8, the vehicles were in factory
new condition with very low mileage. Of the remaining vehicles, all
obtained from rental agencies, the majority are from long term lease
operation and were not in transient rental fleet status. Of the twenty-
five, eight trucks were from the surveillance group and are identified below.

Another drawback was the non-availability of certain displacements
of certain makes. The vehicles available for the required two week period
did not cover as wide a variety of displacements as might have been desired.
The trucks and engine sizes are, however, the most popular - at least in
the Southwest.
It may be noted that only a few vehicles in the recently developed
intermediate class of 6001 to 14, 000-lb GVW were included in this study.
This happened because the space and weight requirements of the CVS and
related equipment and generator set are difficult to employ with one ton and
three-quarter ton pick-ups and stakes (vehicles in the 6001 to 10, 000-lb GVW
range). There are a very small, almost negligible number licensed between
15
-------
10,000 and 15, 500-lb GVW. This may be fortuitous in light of recent
studies and research directed toward operating vehicles from 6001-
14, 000-lb GVW on the current light duty driving schedule. The road
group is therefore comprised of nearly all trucks above 16, 000-lb GVW
and considered to be in heavy duty operation as contrasted to light duty
operation as is more the case of the 6001-14, 000-lb GVW vehicles.
(2) Laboratory Group
This fleet of 145 trucks has been described in detail by reports
covering the periodic emission inspection given the surveillance activity
of the basic contract. Appendix Table D-l is a listing of the vehicles and
their status, mileage, etc. , at the fourth round (12 months of operation)
test. Also shown are the fourth round emission results concentrations
obtained by a chassis version of the prescribed nine-mode FTP. These
emission results are shown to assist in describing the vehicle-engine
make-up of the laboratory group. For purposes of analysis, this fleet
has been divided into 23 categories of engine make and displacement.
These categories are shown in Table A-3. These categories may be
helpful in the analysis of the results disclosed later in this report.
D. Vehicle-Engine Preparation
The two groups of vehicles were prepared slightly differently for testing.
(1) Road Group
These vehicles were subjected to a performance and exhaust system
inspection before start of the test to make certain the engine was adjusted to
manufacturer's specifications and that the exhaust system was tight. Where
found necessary, ignition components such as spark plugs, points and
condensor or wires were replaced, though this was seldom required.
Preparations to the engine involved adjustments to factory settings of
engine rpm and basic timing according to the EPA tune-up sticker on the
engine. Empty, curb, weight of the truck was obtained by weigh scales and
the truck loaded with CVS and other equipment plus drums of water to achieve
a total vehicle weight of curb weight plus one-half net payload. Net payload
weight is herein defined as the license weight minus curb weight.
A suitable trailer hitch for connection of the generator trailer was
added. Generally, the vehicle exhaust pipe had to be extended due to the
length of the bed. This was done by connecting a long tailpipe extension
approximately 1 inch larger in diameter than the conventional short stub pipe
after the muffler. The system was sealed. There were no leaks.
16
-------
The manifold vacuum and engine rpm transducers were installed
as well as the "fifth wheel" for mph. The Metrodata tape data system
was then calibrated, along with two TI dual pen recorders, against
manifold vacuum, engine and vehicle speed. Calibration checks were
made of the CVS using the propane injection method. The fuel line to
the fuel pump was connected to a preweighed 5-gallon fuel container
located in the cab of the truck. The vehicle was then ready for test on
either the road course or on chassis dynamometer. Figures 9 through
13 show views of most of the 25 trucks prepared for road evaluation.
(2) Laboratory Group
No preparations to this group of 145 trucks in the surveillance fleet
were made specifically for the CVS test other than adding a suitable ex-
haust section that would make possible simultaneous sampling by the
continuous cart for the nine mode FTP and by the CVS. This item was
usually 3 ft. in length and replaced the usual short stub pipe from the
muffler or was coupled to it. The exhaust systems on all the surveillance
trucks were inspected and repaired or tightened where required to provide
a leak tight exhaust system. Another item of preparation was to connect
a preweighed fuel container to the inlet of the fuel pump for fuel flow rate
dete rmination.
The surveillance fleet is tested as-received from the owner. If the
basic timing is greater than ±3° and/or the engine idle rpm is more than
±100 rpm of the manufacturer's recommended, tinning and/or idle are
adjusted to factory (sticker) specifications and retest performed. This same
practice was followed with as-received and after adjustment tests made with
the CVS during the fourth round inspection, after 1 year of operation.
E. Fuel
The fuel used during all emissions tests, both road and laboratory, met
the requirements of the Federal Register^) A typical fuel analysis of the
fuel used and purchased locally is given in Table 1.
F. Road Route
The road course used in this project was the same one laid out by
Mr. Bob Olsen (EPA Project Officer of Contract PH 86-67-72) and Mr. Karl
Springer, SwRI Project Manager, several years ago. It was described in
detail in reference 5 as including a variety of truck operation typical of city-
suburban delivery.
The intent was merely to develop a road course that involved several
different types of driving such as arterial, residential, urban congested
(downtown), commercial, and freeway. This course, shown in Figure 14t

includes all these types of driving and the course is one that intentionally
makes the test truck drive traffic where many other trucks commonly
operate. It is 7. 24 miles in length and normally requires about 20
minutes to drive completely around. "Figure 15 contains three photo-
graphs taken from the back of a truck during a test run. The top photo
was taken near point 4, the middle photo on the exit of the Interstate
Highway near point 7, and the bottom photo was taken between points
7 and 1. The drivers are instructed merely to drive normally, stay
with traffic yet not to exceed posted speed limits.
No claim is made about the course as being typical of truck operation
in the U. S. or that is is based on driving habit and patterns that have been
carefully defined. Several years of effort seem necessary to establish a
road driving course that could be agreed to as acceptable and typical of
U. S. truck operation. This was specifically pointed out in the proposal so
that there is no misunderstanding of the basis of the road course used in
this project.
G. Nine-Mode FTP Schedule
The laboratory driving schedule for both the road and laboratory groups
was a chassis dynamometer version of the nine-mode Federal Test Procedure(l
This, version, contained in the proposed Federal Standards'^' an as alternate
to the stationary method was deleted in the June 4, 1968, final regulations'*^'.
Part of the surveillance test fleet was to determine the correlation of
chassis to stationary operated engines on the nine-mode procedure using ten
widely different HDV's. It was found that usually the chassis test was within
±10 percent of the stationary, although for certain contaminants for certain
makes, the difference could be as great as ±25 percent. These findings
are surmnarized in Table A-4 of Appendix A for background information.
The nine-mode FTP, 20 minutes in length, consists of the schedule in
Table 2 which is run four times. The weighting factors, listed in the last
column, are used to calculate the concentration results.
H. General Test Procedure
The road operated vehicles were subjected to a more extensive series
of tests than the laboratory group.
(1) Road Group
Each series consists of obtaining replicate exhaust emissions during the
following:
1. Cold start 9-mode Federal Test Procedure (FTP)
2. Warm start 9-mode Federal Test Procedure

-------
The first two items involved laboratory operation of the prepared vehicle
on several days to obtain replication of both cold and the prescribed warm start
nine-mode data. The "cold start" was made as nearly as possible in compliance
with the light duty cold start requirements for 1972 and later model year. An
overnight soak at 68 to 86° F was observed and the truck CVS and continuous
NDIR cart sampling begun when the starter began cranking the engine. The
normal warm start nine-mode FTP begins after a 5-minute pre-run between
1000 and 1200 rpm and no load. Both raw concentration levels and CVS
samples were obtained simultaneously. The CVS was operated continuously
during the 20-minute version of the test.
The road operation involved normally several days of actual field
operation in order to obtain replicate CVS samples for several different
drivers. Nine tests, three tests for each of three drivers, was the goal.
Sometimes only two tests were made with certain drivers and sometimes four
drivers were used. A small study of driver effect on truck emissions over
a stop-and-go road course was recently made as part of the last procedural
development project on HDV for EPA (Mr. John Bozek, Project Officer).
Pages 72-79 of reference 6, the final report, cover the expected range of
variability for the drivers used on the road course. The stop-and-go
course in which seven truck drivers were tested involved similar driver
functions to that over the SARR and showed statistically that the specific
drivers used in this project would produce fairly similar results. They
were not given any specific instruction or driver training and only asked to
drive normally and not exceed posted speed limits.

IV. RESULTS
The results are discussed in terms of the road and laboratory
group of vehicles and then their combined usefulness is considered.
A. Road Group
The results of the 25 vehicles tested are summarized as follows:
1. Cold Start - Warm Start FTP Results
Table 3 presents the average emission levels for the FTP cold
and warm start tests in terms of both continuous sample volumetric
concentrations and CVS grams/lb of fuel. Average data are shown
based on usually two "cold" starts and three or more "warm" starts.
The actual number of tests is shown in parentheses. One surveillance
fleet truck (laboratory group) was also given a single cold-warm start
series and is shown on Table 3 as truck number 50.
From the results presented in Table 3, it appears that, in gen-
eral, HC cold start emission levels are slightly higher than warm start
levels; while NO cold start levels are generally somewhat lower than
warm start levels by the nine-mode Federal method. The overall average
"cold" start HC was about five percent higher and the NO was about nine
percent lower than the "warm" start. CO was, on the average, unaffected
by the type of start. About 80 percent of the nine-mode average HC con-
centrations from the cold start tests were higher than the warm start tests.
However, the average hydrocarbon concentration from the cold and warm
start tests did not differ by more than ± 17 percent for any of the 25 trucks
tested. The cold start CO concentrations were higher than the warm start
results about half of the time. The difference in average CO concentrations
between cold and warm was between -6 percent and +22 percent. The cold
start NO concentrations showed the opposite trend, with 80 percent of the
cold start average NO concentrations being less than the warm start con-
centrations. The difference in average NO concentrations between cold and
warm start for a given truck test was between -25 percent and +3 percent.
The CVS results from the nine-mode tests showed similar results.
From the testing of this group of trucks, it does not seem to
matter much •whether the nine-mode FTP is run from a "cold" start or
the usual "warm" start. This conclusion is essentially the same as re-
ported on page 66 of reference 6. Although the CVS, which is sampling
continuously, was more sensitive to the "cold" start in terms of slightly
higher HC, the raw exhaust concentration method prescribed by the FTP
is little affected. The method of chart reading and subsequent weighting-
calculation of the mode concentrations is felt to be the reason.

Table 4 lists the CVS results from both the chassis version of the
FTP and the San Antonio Road Route tests. The values listed are CVS
in grams per pound of fuel burned, the only common means of expression
for a given truck thus operated. A number of chassis runs, usually 3 or
more, and a number of road course tests, usually 6 or more by several
drivers, are averaged for purposes of this comparison. Appendix B con-
tains NDIR concentration and CVS emissions individual run results for
all 25 trucks. One table, on which is listed the road and laboratory
results, is devoted to each truck. Please refer to these more extensive
listing of results for an indication of run-to-run repeatability, etc. To
facilitate the comparison, the average chassis test results were divided
by the average road results to obtain a ratio. Ratios less than one indi-
cate the SARR emissions are greater than the FTP, ratios greater than
one indicate the SARR emissions rates were less than the FTP.
Overall, the closed Federal test yielded 83 percent as much HC,
70 percent as much CO and 120 percent as much N©2 as did the road
course. This bears out the fact that the current FTP is a high NOX pro-
ducer. Although some variability was noted, especially for some makes,
the range of comparison ratios is surprisingly good.
For HC, the 25 trucks ranged from a 0. 51 up to 1. 27 ratio, while
CO ranged from 0. 17 to 1. 32. NOX varied from 0. 69 to 1.61. Except for
CO, the average ratios are not substantially away from unity or one-to-one,
direct, correlation. Fuel rate or fuel consumption indicated that the energy
inputs to each procedure were not grossly different, the FTP consuming
on an average of 80 percent as much fuel as the road course.
These findings agree quite well with a similar series of tests with
six pre-controlled (1968-1969) trucks. The results, described in Reference
5, are repeated as Table 5 for direct comparison. The major difference
was that NO was measured by NDIR instead of CJ_ and will be somewhat
lower than the data in Table 4 due to unavoidable conversions. Except for
CO, the pre-controlled six truck fleet gave almost identical FTP/SARR
ratios. Emission rates of HC and CO were quite similar between the two
groups.
The 25 truck road results, discussed so far in general terms,
may be considered by several other ways. The first was to group the
engines by make and displacement. Figure 16 is a bar chart which illustrates
the data thus summarized and, where more than one engine was involved,
averaged on Table 6. In effect, Table 6 is merely a rearrangement of
Table 5 data with the grams per pound of fuel of HC, CO and NOX as measured
over the S. A. road route combined in a "stacked type" bar chart on Figure
16. For purposes of this representation, HC, CO and NOX were each given
equal importance and, the specific value, shown on the bar graph.
If one were to rank order HC, CO, NOX and the total HC + CO + NOX
(assuming equal weight or importance of each contaminant) the order shown

on Table 7 -would be found, going from low to high. Table 7 is based on
only the 25 SARR trucks and emissions in grams per Ib of fuel. In so
doing, no really clear trend of make alone may be noted but, make and
displacement seems to be the predominant variable. This conclusion is
consistent -with exhaustive statistical analysis of the surveillance fleet, the
145 truck laboratory group, -which revealed engine make and displacement
to be the most significant variable in exhaust emissions by the nine-mode
FTP, reference 12.
Another way to consider the results is by weight classes using
the conventionally used breakdowns as used by the Motor Vehicle Manu-
facturers Association) ) MVMA. The 25 trucks were grouped by gross
vehicle weight, GVW, class and their SARR emission rates in grams per
pound are listed on Table 8. Using the stacked bar chart approach, the
average emission rate for each weight class are shown on Figure 17 and
compared to the overall average of the 25 trucks. Total emission rate,
•with each contaminant given equal weight, showed an overall increase
•with -weight class. The 6001-10,000 GVW class were based on a single
make and displacement and should be used with caution in this analysis.
It is interesting to note the steady increase in hydrocarbons-with weight
and the overall increase in CO with weight. One exception was the large
amount, 197 grams per pound of fuel, produced by the 16, 001-19, 500 Ib
class. NOX for the three highest weight classes •was essentially constant
•with the single 6001-10,000 class vehicle make and size showing sub- .
stantially higher NOX, 15.4 versus about 9 grams per pound of fuel, than
the other three classes.
A third way to examine the road route truck results is to group
.the trucks into function by size and type. Since the fleet size was rela-
tively small, it was decided to separate them as small, intermediate and
large. The small category represents the three similar Ford 300 CID vans
of 10,000-lb GVW.
The large category was based on the six truck tractors representing
three makes and four displacements with tractor GVW from 24, 000 to 32, 500-
Ib GVW. Gross combined weight, when pulling a trailer, will be fifty to
seventy five percent greater than the tractor and really depends on number
of axles and tire size as mentioned earlier. The remaining trucks repre-
sent single drive axle vans and stakes used in delivery and service appli-
cations. This category includes the bulk of the trucks, 16 trucks repre-
senting five makes and nine displacements with 16,000 - 32,000 GVW.
Table 9 lists the results for the 25 trucks grouped by size and type.
Figure 18 illustrates the road emissions in grams per pound of fuel as in
Figures 16 and 17. As anticipated, the size and type of truck trend follows
the same general upward trend, in overall rate, as shown in Figure 17
since only single make and displacement was tested.

FIGURE 18. COMPARISON OF SARR COMBINED HC, CO, AND
NOX EMISSION RATES, GRAMS/LB FUEL, BY SIZE AND TYPE
43
-------
The Figure 18 comparison is more meaningful in some ways
than.by strict GVW as in Figure 17. The trend of lower NOX and CO
going from "small" to "large", and higher HC going from "small" to
"large" is consistent with the way these engines are used and their
duty factor. More higher power operation is involved as one progresses
from "small" to "large". Since the displacements of the engines, and
their rated power does not follow the increases in GVW as a direct function,
it follows that the engine is working harder in the "large" category than in
the others. The trends in HC, CO and NOX are quite consistent with sta-
tionary and chassis dynamometer data and road studies conducted under a
related procedural development project, Reference 6.
3. Vehicle-Engine Performance Data
In addition to measuring emissions during Road Route operation,
engine and vehicle performance was also recorded on magnetic tape using
an automatic data acquisition system. Engine speed (RPM), maniford
vacuum (in. Hg. ), vehicle speed (MPH), and throttle position were recorded
approximately twice a second. These data were reduced by a computer
program to give percentage of time spent at various increments of engine
speed, vehicle speed and manifold vacuum.
Table 10 is an overall average of the way in which the 25 trucks
operated the road course. Also shown are the max and. min values recorded
by the group to give some idea of the variability. Little more in the way of
analysis of these results can be done at this time. It may be that this data
and the detailed truck results, given in Appendix C to this report, will prove
of use to the Procedural Development Section of EPA in comparing to the EPA
analyzed Ethyl truck and bus survey data^ ' (Mr. Preben Ostberg, EPA) or
the APRAC Cape 21 project on HDV driving patterns (Mr. John Bozek, EPA
or Mark Sherbinsky of IHC). Although six to nine road runs were made for
emissions, not all tests were computer reduced for vehicle-engine operation.
One, and many times two, runs were selected at random and processed.
These computer print-outs are included in Appendix C.
B. Laboratory Group
CVS and concentration tests were made per the nine-mode FTP, chassis
version, with the laboratory group of 145 surveillance vehicles at the fourth
round inspection (after 12 months of operation). A listing of the results is
contained in Appendix D. Table D-l shows the results by the FTP continuous
NDIR cart in terms of HC as ppm N. Hexane, CO and CO£ as percent and NO
as ppm. These fourth-round results are summarized on text Table 11 along
with the first three rounds for comparison. The average emissions from the
fourth round may be seen to be quite similar to the first three inspections.
Tables D-2 through D-5 are fourth round HC, CO and NO (observed
and corrected) by engine make - displacement category. The listings are in

ascending order of the mean values. Table D-6, in Appendix D, lists the
as-received test CVS results in terms of grams per pound of fuel burned
and grams per test. This data, like that listed in Table D-l, was for the
vehicle in as-received condition.
To summarize this extensive series of tests, text Table 12 compares
the average, maximum, and minimum emissions in grams per minute, and
per pound of fuel for all 145 trucks to the road group. The surveillance fleet
of 145 trucks resulted in average nine-mode Federal test emission levels
not greatly unlike that of the 25 road trucks. The comparison of the
concentrations by NDIR are shown on top of Table 12.
The average HC and NO concentrations for the 25 truck group were
slightly lower than the 145 truck fleet, 265 vs 273 ppm n. Hexane and 1602
vs 1703 ppm NO corrected. CO was higher, 2. 19 vs 1. 79 percent. The
range of values, maximum-minimum value, were greater for the larger
fleet as expected except for CO.
Shown next on Table 12 is a comparison of the surveillance or
laboratory fleet to the road group average results when the nine-mode
Federal test was sampled continuously during the 20-minute run (closed •
test). The CVS results on a gram per minute basis showed the road group
to emit higher rates of HC (3. 63 vs 3. 2), CO (28. 45 vs 43. 1) and NOx-as
NO,? ( 3. 9 vs 3. 65). Based on grams per pound of fuel, essentially equivalent
HC was produced with higher CO but slightly lower NOX.
0
The range of results as well as the averages are important-from the
standpoint of validating the smaller, 25 truck, fleet. Apparently, one of
the vehicles, truck 21 of the road group, had excessive CO by the FTP and
this is the reason for the higher maximum, which also overly influenced
the average. The truck ran satisfactorily and was within factory tune
specifications otherwise. The next nearest high CO unit was number 17
with 121 grams per minute versus 186 grams per minute.
Appendix Tables D-7 through D-9, like Tables D-2 through D-5,
list the HC, CO and NOX for the 23 classifications of engine make and
displacement in ascending order. These breakdowns of the results are
furnished for possible use by EPA in estimating national impact values.
Comparing the maximum divided by the minimum grams per test values
(CVS) to the same type ratio for the concentration data, per test, it may
be seen that the CVS tracks the NDIR system at least in response to the
driving cycle. If the NDIR system showed a large variation for CO, for
instance of say about 30 times (4. 90/0. 15), the CVS also showed about the
same (1513/44). Some strength and confidence in the test and test results
is gained by these indications.
Appendix Tables D-10 and D-ll list the results of NDIR concentration
and CVS emissions on those vehicles that required tune adjustment and

were retested as part of the fourth round inspection. For completeness,
CVS data was obtained along with usual concentrations where timing was
greater than i-3° and/or idle speed was greater than ±100 rpm of factory,
sticker, specification. Appendix Tables D-12 and D-13 indicate the per-
cent difference the adjustment makes on emission rates. The CVS dif-
ferences, on Table D-13, are based on grams per test. In the event the
data on the surveillance fleet should all be on an "in-specification" basis,
the data in Tables D-10 and D-ll can be substituted into Tables D-l and
D-6.
C. Use of Results
There are many uses that can be made of the results in this report.
As an example, suppose it is desired to determine from as large a data
base as possible, the road emissions of HC, CO and NOX on a grams per
mile and/or a grams per Ib (or gallon) of fuel.
It appears that a usable correlation of road to chassis emissions
has been developed. Further tests with similar year model and size
gasoline trucks should improve on this relationship but are not expected
to materially change it. The following factors, however, could be used
to estimate impact. These are simplified in that they assume the 25 truck
results reflect the population, both in number and composition. They also
assume that the S. A. R. R. gives emissions that are not unlike trucks
driven in urban areas nationwide.
HC: Divide chassis results by 0.83 to get road emission rate
CO: Divide chassis results by 0. 70 to get road emission rate
NOX as NC>2'- Divide chassis results by 1. 20 to get road
emission rate
These factors may be used on the 145 truck laboratory group (surveil-
lance fleet) CVS results (chassis version of FTP) to get road emission rates
based on a large number of vehicles. Using the data (mean values) from
Table 8, these values for HC are:
Road HC: grams _ 11. 03 grams HC (_!__ \ - 13. 29 grams HC
pound of fuel pound fuel 0.83 pound fuel
for the fuel used, API Gravity 59.3° at 60/60 and
density is 6. 24 pounds per gallon .
grams HC _ 13.29 grams HC ( 6. 24 pounds ^ _ 82.93 grams HC
gal of fuel Ib of fuel gallon gallon
49
-------
There are many ways to use this value to obtain a simplified, un-
weighted impact for say an average truck. Assuming the average truck
travels 12,329 miles per year (from the first year of surveillance project)
with a fuel consumption of say 5. 68 miles per gallon (from the 25 truck
road operation) then the average vehicle's HC emissions may be estimated
as
Road HC for an . 82. 93 grams HC , gallon . , 12, 329 mi. 180, 007 grams HC
avg. truck gallon 5. 68 mi. year " year
The same simplified approach can be used to determine CO and NOX as NO2-
The equations may be written as:
Road CO for an _ 97 grams CO / 1 \/6.24 Ibs fuelwgallon \/12, 329 miles\
average truck Ib fuel 0. 69 gallon 5. 68 mi year
1, 904. 087 grams CO
year
Road NOX as NO2 for 13.47 grams NOz 1 6. 24 Ibs fuel gallon
an average truck Ib fuel ' M.20 '* gallon ' ^5.68 miles'
12, 329 miles 152, 037 grams NO2
year year
Then, the above could be multiplied by the total number of trucks in
operation to obtain yearly contribution of trucks above 6, 000-lb GVW.
It must be emphasized that these calculational approaches are ex-
tremely simplified and based on a number of assumptions. A better, more
dependable, method would be to use the data from the 145 vehicles by engine
make and displacement and determining, from the population of these dif-
ferent makes and displacements their yearly mileage and fuel consumption
rates. This approach, however, is more difficult because of the general
lack of data on population, usage, mileage, and fuel consumed.
It may be possible to weight the 145 truck results, as well as the road
group results to national sales or population by make and engine displacement
and possibly vehicle size. Fairly good statistics are available by make or
GVW (but not make and GVW) as far as national population is concerned but
a breakdown by make, displacement, as well as size has not been uncovered
by our staff. Since this is beyond the scope of this project and could well
be a sizeable job of its own, nothing further in this regard has been done.
what good it may be, the operating experience gained with the
23 classifications is presented in Appendix D as Table D-15. The mileage
values are for the first 12 month period covered by the surveillance fleet.
The fuel consumption of the 25 road operated vehicles determined by direct
50
-------
measurement over the 7. 24 mile long S. A. R. R. was shown in Table 4.
Recall that a fuel factor or ratio was computed and shown on this table.
It is possible to use this factor with the fuel consumed in pounds for each
vehicle make and CID class with the entire 145 truck fleet, This would
result in a Ibs of fuel per road route of 7. 24 miles. Thus, a gross or
overall fuel consumption (mpg) could be determined at least for the 145
trucks had they been operated on the S. A. R. R. To illustrate, the following
is offered:
S. A. R. R. Road Fuel. miles . 7. 24 miles. FTP Test. ,Q ? .
Consumption ' gallon S. A. R. R. 5. 65 Ibs
,6.24 Ibs, , .,

where 5. 65 Ibs is the average fuel necessary for the 145 trucks to
test operate on the Nine-Mode 20-min chassis test
6. 24 Ibs is density of fuel
gal
&
0. 79 is the factor FTP fuel Ibs , determined by 25

truck fleet.
This miles per gallon could be used in the previous equations as well as the
average mileage per year to define the road emissions in grams per year for
the 145 truck fleet. The question then remains, how representative of the
national population is this fleet in composition and number of vehicles per
classification. At this point, the fleet results could be weighted by popula-
tion statistics, to the extent available, and then an average vehicle fuel rate
(mpg) and yearly mileage accumulation to gain a more accurate estimate of
tailpipe emissions contribution.
Little has been said about the usefulness of the nine-mode FTP fourth
round results obtained simultaneously with the CVS by the continuous NDIR
system per the usual procedure. First, the agreement between the road
group and the laboratory, surveillance, fleet can be examined on an emis-
sions and fuel consumed basis. The mean, maximum and minimum values
are shown in Table 13.
*
From this table, the two groups seemed to demonstrate fairly close
and comparable average values. The maximum and minimum values did
not show the extremes, in the case of the smaller road group as were
shown in the larger group of 145 trucks.

The other major use of the concentration results is to compute, even
if crudely, a factor that could be used to relate the nine-mode FTP concen-
trations to grams per mile over the road course. It may be helpful to have
a rough idea of what current and projected standards would be equivalent to
in mass per mile. This may be especially helpful if current national estimates
have been related to Federal concentration limits.
One way to do this would be to determine what one ppm n. Hexane
is equivalent to in terms of grams of HC per mile.

For the 145 truck laboratory fleet, the average HC was 273 ppm n. Hex by
the nine-mode test. Assuming both fleets, the laboratory and road, represent
not only population but usage nationally, a big assumption, the contribution of
trucks on a per mile basis could be determined as follows:
Fleet HC
(145 truck surv.)
. (273 ppm n. Hex) ^ 0.0607 grams HC ). 16.57 grams HC
1 ppm n. Hex - mile mile
average truck
Also, the current and earlier proposed Federal limits can be related to
road emissions as follows:
52
-------
Current Limit HC - 275 ppm n. Hex / 0.0607 grams HC t _16. 69 grams HC
(275 ppm n. Hex)' 1 ppm Hex - mile mile
Proposed 1973 Limit. HC = 160 ppm Hex 0. 0607 grams HC . = 9. 71 grams HC

would be:

In using the above in national impact, it must be recalled that it is
assumed that the 25 vehicle and 145 vehicle fleets represent national population
and usage. The strength of this assumption is unknown and accordingly, the
factors and their usage must be with care.
53
-------
To this point, the usage of the results has been limited to the over-
all average of the entire 25 trucks. Tables 6, 8 and 9 grouped the results
by engine-CID, GVW class, and size-type respectively. The average
emission rate for each sub-group of the twenty-five vehicles could be used
to estimate impact where population and usage statistics are available. The
engine make-displacement data (Table 6), though probably the best break-
down, will be somewhat difficult to use in national impact assessment
without better statistics of engine make and displacement by GVW. This
type of breakdown appears difficult to obtain.
The GVW class data, of Table 8, may come nearer matching the
statistics (population by make) breakdowns normally found in Automotive
Industries or Motor Truck Facts (MVMA) statistical publications. How-
ever, the less precise or involved the breakdown, the less precise the
resulting estimate will be in general.
In conclusion of this section, there are a number of ways to extend
the data obtained by the road group to_the national population for estimation
of emissions impact. The calculation methods discussed in this section
are fairly crude and may be vastly improved, depending on the time, effort,
and'availability of satisfactory truck statistics. The latter may be the
biggest stumbling block to fairly precise nationwide estimates.

V. SUMMARY
A group of 25 1970-1972 model year gasoline-powered trucks above
6000 Ibs GVW were operated on the road and in the laboratory to obtain
mass rates of emissions of HC, CO, and NOX to aid in determining na-
tional impact of heavy duty trucks. This report describes the results and
how they were obtained from both operation over the San Antonio Road
Route and in the laboratory using a chassis version of the nine-mode Fed-
eral Test Procedure.
A large, 600 CFM size CVS was used to acquire dilute samples
of exhaust during both road and laboratory operation. The CVS and related
equipment was loaded into the truck, along with additional weight to equal
empty weight plus half payload and a trailer mounted 20 KW generator
set, for electrical power and operated continuously over the 7. 24 mile ap-
proximately 20-minute road course. The route included a variety of streets
as well as traffic and is intended to represent trucks "driving traffic".
The same equipment and truck was then operated on a closed, continuously
sampled, chassis dynamometer simulated nine-mode Federal Test normally
and on a "cold-start" basis. In both tests, the quantity of fuel consumed
was measured so that the road and laboratory test emission rates, computed
in grams per pound of fuel, could be directly compared for a given truck.
To define how each truck operated over the San Antonio Road Route,
a continuous record of engine speed, vehicle speed and manifold vacuum
was obtained by strip chart and magnetic tape. Several drivers were
used to obtain replicate tests with one or two runs computer reduced to
indicate percent time at various increments of engine rpm, vehicle mph
and manifold inches of mercury.
To extend the 25-truck road group to a larger data base, the 145
truck surveillance fleet of 1970 and 1971 trucks were tested by the closed
nine-mode CVS method. These tests were performed at the scheduled
1 2-month inspection and obtained simultaneously with the usual concen-
trations of emissions according to the Federal procedure. As with the
road group, the emission rates were expressed in grams per pound of
fuel.
The road results are summarized by engine-vehicle make and
displacement, vehicle GVW class and size-type of truck and compared
to the overall average of the 25 trucks. Although all attempts were made
to adequately represent all makes and sizes of significant population,
the fleet size and the availability of trucks for this purpose was limited.
A total of six makes and 13 displacement were included ranging in GVW
from 10, 000 to 32, 500 Ibs. The six tractors tested could have gross
combined weights on the order of 50, 000 Ibs when coupled to a trailer.
55
-------
A section of the report considers several possible ways the road
group results may be used to help in predicting national emissions impact
from heavy duty trucks. Using grams of contaminant per pound fuel as
the common method of expression, relationship between the road and the
surveillance fleet test results are developed.

VI. CONCLUSIONS AND RECOMMENDATIONS
The following conclusions and recommendations are offered for
consideration as a result of this project.
1. Replicate "cold" and normal "warm" start nine-mode Federal
tests indicated in general the "cold" start to result in slightly higher HC
and slightly lower NOX. This was found to be the case in about twenty
of the twenty five trucks. The average "cold" start HC was about five
percent higher and the NOx was about five percent lower by the nine-
mode Federal method. The closed CVS test of the nine-mode method
"cold" start average HC was about nine percent higher and NOX nine
percent lower than the usual warm start. CO was unaffected by type
of start. It is doubtful whether a cold start version of the current
Federal method is justified although it may be of interest with a dif-
ferent driving schedule.
2. The agreement between the two test methods, the laboratory
closed nine-mode Federal method simulated on a chassis dynamometer
and the 7. 24 mile San Antonio Road Route was satisfactory and similar
to the agreement found in an earlier project with six pre-1970 trucks.
Based on CVS results with emissions expressed in grams per Ib of fuel
consumed, the Federal test yielded 83 percent as much HC, 70 percent
as much CO and 120 percent as much NOX as did the road course. The
nine-mode test is a high NOX and low CO producer relative to driving
traffic over this specific road course. Overall, the test results are
close enough to unity to provide a meaningful relationship between the
two procedures.
3. Several parameters were found, within the 25 truck road
group, to have an effect on total emission rate, giving equal importance
to HC, CO and NOX.
a. As found in other gasoline heavy duty studies, engine
make and displacement continue to have the greatest influence on emis-
sion rate. There are differences in emissions due to engine make and
to engine displacement that are apparently due to design and not
necessarily the type of test.
b. Weight class of vehicle was shown to have a noticeable
effect on total emission level. Namely, as weight class GVW increased,
total emission rate, in grams per pound of fuel on the road route,
increased.
c. Size and type of vehicle, whether "small", like a 10,000-
Ib delivery van, "large", defined as a truck tractor semi-trailer com-
bination or "intermediate", between "small" and "large", was shown to
57
-------
have an effect. Going from "small" to "large" total emissions in grams
per Ib fuel increased, HC and CO increased and NOX decreased. This
illustrated the greater utilization of the available power of the engines
since their displacement increased only slightly relative to the size
and weight carrying capacity.
4. The surveillance fleet of 145 trucks resulted in average
nine-mode Federal test concentrations not greatly unlike that of the
25 road trucks with HC of 273 versus 265 ppm n. Hex.-, CO of 1. 79 ver-
sus 2. 19 percent and corrected NO of 1703 versus 1602 ppm. The CVS
HC and NOX test results were likewise quite comparable with CO being
substantially higher from the road group. Although in general the road
group average levels were similar to the larger surveillance fleet, the
range of levels were broader for the surveillance fleet. This type of
comparison tends to validate the size and make-up of the road fleet for
use in national impact estimation.
5. One feature of the project was to define the way each truck
operated over the road course in terms of percent time spent in a given
increment of engine speed, vehicle speed or intake manifold vacuum.
Although the analysis of the data was carried only to the point of com-
puter reducing one or two runs per truck, the results may be quite
helpful in assessing driving habits, patterns and truck use. Its ap-
plication to the study and development of improved test procedures is
left to a future project. Full use of the data is recommended in the
current CRC-APRAC CAPE 21 project.
&
6. The emissions data obtained from the 25 trucks may be used
in a number of ways to estimate national impact. One of the easiest
is to approach impact through fuel consumed and miles driven for
gasoline trucks above 6, 000-lb or some other weight level. The 25-
truck road data can, with or without the use of the surveillance fleet,
be used to compute tons per year of HC, CO and NOX. The reliability
of the estimate will, to a great extent, depend on the availability of
sufficient truck population and usage data for assessment on some basis
other than overall averages. The 25 trucks represent a number of makes
and models of engines and applications popularly used. They are by no
means directly representative of the truck population, although the
results by make, displacement, and GVW could be weighted to national
population given adequate statistics. Although beyond the scope of this
project, it is highly recommended.
7. It may be desired to gain more information on other heavy
duty gasoline vehicles over the San Antonio Road Route in a manner
similar to this project. Additional pre-controlled pre-1969 vehicles
may be of interest to indicate gasoline truck emission levels prior to
controls which began in 1970. Comparison of the 25 controlled to an
58
-------
earlier group of six pre-controlled showed higher HC and CO with NOX
comparison not possible because of the use of different instruments and
NO to NO2 conversion between the two programs.
8. Diesel powered trucks could be operated over the road
course in a manner similar to the gasoline trucks with the addition of
a continuous heated flame ionization hydrocarbon analyzer and a
continuous indication of engine fuel consumption. Although never
done before on the road, it may be possible to gain emission rates
and vehicle-engine performance to assist EPA in assessing national
impact from this source.

16. ABSTRACT
Mass emission tests were run on a number of gasoline powered trucks above 6,000-1b
GVW during road driving and chassis dynamometer operation. A constant volume sample
was used to obtain samples during operation on a 7.24 mile course in San Antonio and
during the entire 20 minute nine-mode FTP. The agreement between the road and dynamo
meter results, in terms of grams of emission per pound of fuel, was used to determin
what road emissions would be from a larger, 145 vehicle, fleet that was subjected to
similar CVS nine-mode FTP tests in the laboratory. Consideration of the end use of
the data was made with preliminary expressions developed for possible use in deter-
mining the contribution of gasoline HDVs to air pollution. Data was provided to
assist in better estimating national impact from this source. A group of 25 trucks
representing a variety of makes, displacements and gross vehicle weights were studie
and extensive road and dynamometer hydrocarbon, carbon monoxide and oxides of
nitrogen emission data are included. Also included are percent of time at various
increments of engine speed and manifold vacuum and vehicle speed that define how
each truck operated in traffic over the road course.
