ABSTRACT
During this work effort a series of inspection and restorative maintenance actions
were performed on a sample of nine 1975 through 1977 vehicles ramdomly selected from
the St. Louis metropolitan area. Each vehicle within the test sample had been driven a
minimum of 75,000 miles prior to acceptance into the program.
A sequence of emission tests were performed before and after all adjustments or
corrective maintenance. Such test sequences consisted of a Federal Test Procedure, a
Highway Fuel Economy Test, the Federal Short Cycle, a Two Speed Idle Test and the
Federal 3-Mode Test.
While in their as-received condition, each vehicle was subjected to a sequence of
tests followed by an inspection for engine maladjustments and intentional disablements
to the emission control system. Any problems discovered during this examination were
corrected and the vehicle was retested. An Emission Component Function Check was
performed after the initial inspection and any subsequent tests. This procedure included
an evaluation of each component in the emission control system. All malfunctioning or
defective components were repaired or replaced after the Emission Component Function
Check. Following a retest of the vehicles, each was fitted with a. catalyst bypass and
tested again. The bypass units were then removed and a new catalyst was installed prior
to a final test sequence.

1. INTRODUCTION
The United States Environmental Protection Agency (EPA) is charged under the
provisions of the Clean Air Act with responsibility for the control and prevention of air
pollution. In order to fulfill these responsibilities the EPA designs, conducts and
promotes surveys and studies of air pollution sources.
National programs to characterize and reduce air pollution from mobile sources are
developed and implemented through the EPA's Emission Control Technology Division
(ECTD). Mobile emission control strategies developed by the ECTD are based, in part,
on projections of nationwide motor vehicle emissions. These projections are derived
from surveys designed to obtain emission data from representative samples of in-use
vehicles.
A significant portion of the current urban pollution is contributed by those vehicles
with accumulated mileage in excess of 75,000. These vehicles are known to have
emission levels far in excess of others in the national vehicle population as a result of a
combination of factors including worn engine parts and certain maintenance practices
(e.g. richer idle settings) commonly followed for high mileage vehicles.
Corrective actions, such as readjusting basic engine parameters or connecting
unattached hoses, lines and wires, can cause a sharp decrease in exhaust emissions at a
relatively low cost. Other maintenance requiring replacement or repair of defective
parts may result in similar exhaust emission decreases but at a higher cost.
During the past several years, the EPA has conducted a series of restorative
maintenance programs designed to ascertain the emission related benefits of various
corrective maintenance actions. Information derived from these projects is expected to
be used as a guideline for developing a cost efficient approach to vehicle inspection
programs now under consideration by various states.

-------
In July of 1978, Automotive Environmental Systems, Inc. (AESI) subcontracted with
Automotive Testing Laboratories, Inc. (ATL) to perform a restorative maintenance
program for the EPA in the St. Louis metropolitan area. In addition to this work, the
EPA authorized an expansion of the work effort to include an evaluation of catalytic
converter performance on each of the nine vehicles selected for the restorative
. . i ...
maintenance project. This additional work was performed as part of an existing contract
between the EPA and ATL.
The following report details the design and conduct of the project and presents
relevant data*.

2. TECHNICAL DISCUSSION
2.1 PROGRAM OBJECTIVES
This work effort was performed to provide quantitative data on the emission-
related .benefits of restorative maintenance performed on high mileage vehicles. The
program consisted of a series of exhaust emission and fuel economy tests performed on
nine vehicles both before and after each segment of an inspection and maintenance
procedure.
Inspection and maintenance actions were designed to provide a systematic
means of identifying and correcting emission control system failures. Exhaust emission
and fuel economy tests were performed to gauge the relative decrease in emissions
resulting from maintenance actions. Catalyst efficiency was also evaluated by
comparing emission test results obtained while the converter remained intact with those
obtained using a catalyst bypass and those measured after a new catalyst had been
installed. '
2.2. PROGRAM DESIGN
Testing was performed on a sample of nine catalyst-equipped, 1975 through
1977 model year vehicles randomly selected from a list of potential test vehicle owners
in the St. Louis metropolitan area. Each of these vehicles had been driven a minimum of
75,000 miles.
Upon arrival at the laboratory, candidate test vehicles were physically
examined to screen those which had been extensively modified or were unsafe to
operate. Once accepted into the program, the vehicles were prepared for testing and
following a brief driveability evaluation, placed in soak for a period between 12 and 24
hours.

After soaking, a series of tests were conducted to establish the as-received
level of emissions for each vehicle. This test sequence was repeated without modifi-
cations at various designated intervals in the program and is comprised of a driveability
evaluation, a 12 to 24 hour soak, a Federal Test Procedure, a Highway Fuel Economy
Test, a Federal Short Cycle Test, a Two Speed Idle Test and a Federal 3-Mode Test.
A Maladjustment and Disablement Inspection was performed after the initial
as-received tests. During this examination each vehicle was inspected for modifications
to the emission control system and maladjustments to basic engine parameters. Parts
and systems found to be deficient due to normal wear or production faults were termed
"defective" and noted for later corrective action. Purposely disabled or maladjusted
components were identified and repaired at this time. Those vehicles that received
maintenance or adjustments during the inspection were subjected to another sequence of
tests before progressing to the next segment of the work effort.
Following the inspection and any subsequent tests, the entire sample received
an Emission Component Function Check. During this examination, the performance of
each component within the emission control system was evaluated according to proce-
dures specified by the manufacturer. Those components found to be malfunctioning were
corrected immediately following the inspection as were defective parts identified during
the Maladjustment and Disablement Inspection. In several cases, these repairs were
performed with the assistance and guidance of the appropriate manufacturer's repre-
sentative. When necessary, replacements were made with parts designated as original
equipment by the manufacturer. An additional test sequence was performed after the
repair procedure to establish the cumulative effects of corrective maintenacne. . . '
Upon completion of the after-maintenance test sequence, catalytic con-
verters were removed from each vehicle and replaced with a .bypass unit. These units
were constructed with baffles to simulate the average backpressure created by a
catalyst. A sequence of tests was then performed. Following these tests, a new catalyst
2-3
-------
was installed and after 50 miles of conditioning on city streets, a final test sequence was
conducted.
2.3 TEST VEHICLE PROCUREMENT
2.3.1 Test Vehicle Procurement Plan
The nine vehicles selected for this work effort were procured from the St.
Louis metropolitan area using random sampling techniques and certain vehicle selection
criteria supplied by the EPA. Vehicles eligible for testing were limited to those 1975
through 1977 model-year passenger cars with accumulated mileage in excess of 75,000.
Each was operated regularly within 15.5 miles of the St. Louis city limits. Specifications
for test vehicle regarding model year, make, engine displacement, body size, transmission
type and number of carburetor Venturis were supplied by the EPA Project Officer.
Candidate vehicles were identified and acquired primarily through the use of
mailing lists. These lists were purchased from a company with specialized vehicle/owner
records and statistical data. Potential sources were limited to those with required
model-year vehicles living within specified zip code areas. ;
Owners of eligible vehicles were contacted by mail and asked to complete
and return a post-paid information reply card approved by the Office of Management and
Budget. Each reply card was attached to an EPA-approved introductory letter
explaining in a general manner the nature of emission tests to be performed and the
benefits available to participating owners. However, St. Louis Restorative Maintenance
vehicles were acquired and tested concurrently with FY77 Emission Factors Program
testing. Because they represented only a fraction of the total vehicles tested in St.
Louis, introductory letters only addressed Emission Factors Program testing. A more
complete explanation was given to the owners at a later point in the test vehicle
selection process.
2.3.2 Incentives for Owner Participation
The following incentives were provided to owners of test vehicles to
2-4
-------
questionnaire results. ATL normally determined a vehicle's qualifications for the
program although more complex decisions were made jointly with the EPA. Table 1 on.
Page 2-2 summarizes the test vehicle sample according to make, model year,
odometer reading, engine displacement and number of cylinders. As shown in the table,
GM, Ford and Chrysler are equally represented with 3 vehicles each.
2.3.4 Test Vehicle Preconditioning Procedure
Following acceptance into the program, the test vehicles' fuel tanks were
drained and one-pint samples were made available for possible analysis by the appro-
priate manufacturer's representative and the EPA. Each vehicle's tank was then refilled
to 40% capacity with Indolene test fuel. Tires were also rearranged to prevent the use
of badly worn or snow tires on the dynamometer.
The canister system on each test vehicle was preconditioned to assure
uniform test conditions throughout the work effort. A "slave" canister was installed on
all six Chrysler and GM vehicles. This was accomplished by disconnecting (at the
canister end) the outlet hose extending from the vehicle canister to the air filter unit
and reconnecting it to the slave canister. Because of the configuration of Ford canister
systems, a different preconditioning procedure was required for these vehicles. Canister
systems on Ford cars were disconnected at the air filtering unit end of the outlet hose.
Both the canister outlet hose and the air filter hose opening were then taped. No slave
canisters were installed on these vehicles.
Vehicle performance characteristics were evaluated during a 10-minute
driveability evaluation performed immediately after test preparation procedures. This
brief evaluation was used to purge remaining as-received gasoline in the vehicle's fuel
system and to prepare test personnel for any operating problems which might affect
subsequent tests on the dynamometer. -
2.4 HIGH MILEAGE RESTORATIVE MAINTENANCE TEST PLAN
High mileage restorative maintenance vehicles were eligible to receive a
2-6
-------
encourage participation in the program:
A. A $50.00 U.S. Savings Bond
B. Return of the owner's vehicle with a full tank of .fuel
C. Use of a late model, fully insured loan vehicle while testing was being
conducted
2.3.3 Test Vehicle Selection and Screening Criteria
Those vehicle owners that returned information reply cards were contacted
by telephone after a preliminary comparison between the EPA's vehicle list and reported
information. At this time, the vehicle owner was informed of the tests that would be
performed in connection with the Restorative Maintenance Program. Each owner was
questioned regarding the nature of recent maintenance and the extent of any driveline
modifications. Owners were also asked for permission to perform a major tune-up and
told that vehicles selected for the program would be returned in a condition that would
allow them to pass federal emissions standards. If the owner remained willing, the
vehicle was scheduled for delivery to the laboratory for a physical inspection and
screening procedure.
Prospective test vehicles were given a thorough examination for test
suitability upon their arrival at the laboratory. Oil and transmission fluid levels were
checked, vehicle exhaust systems evaluated and tires were inspected for unusual wear.
A sample of fuel was drawn and tested. Previously acquired information was
rechecked. A brief emission control inspection was also performed to screen those
vehicles that had undergone misadjustments or modifications which were not readily or
inexpensively restorable.
Vehicle owners were asked to complete a questionnaire while the pretest
inspection was being performed. This four page form consisted of 38 questions designed ,
to detail the history of the vehicle including the extent of use and the nature of recent
maintenance.
f
Test vehicles were accepted or rejected on the basis of the inspection and
- 2-5 - -:-.-' ''...-'
-------
maximum of five test sequences; one to establish as-received emission levels, one or two
sequences associated with inspection and maintenance procedures, and two performed in
connection with catalyst evaluations.
Testing was conducted according to the vehicle flow diagram on the following
page. Specific actions are designed in the chart by rectangles while diamond shaped
figures represent decision points in the testing sequence.
Each test sequence performed during the work effort was comprised of the
same series of tests: a Federal Test Procedure (without evaporative emission tests), a
Highway Fuel Economy Test, the Federal Short Cycle Test, the Two Speed Idle Test and
the Federal 3-Mode Test. Prior to each sequence, vehicles were refilled to 40% capacity
with Indolene fuel, given a 10-minute driveability evaluation and soaked for a 12 to 24
hour period.
Test sequences were followed by a procedural review designed to assure that
exhaust emission tests had been performed as prescribed by the EPA. This review
included an examination of dynamometer settings (inertia weight and horsepower),
temperature readings and driver's trace tolerances. Other test parameters were also
reviewed for mechanical or operational errors. If any problems were discovered the
vehicle was resoaked and tested again.
If no immediate errors were identified during the test validation procedure,
after test measurements were performed and the vehicle was prepared for the next day's
testing. After test measurements were performed and the vehicle's basic engine status
relative to manufacturer's recommended settings for idle CO and HC, timing, dwell (if
applicable) and idle rpm. .
Following screening and preparation procedures, all vehicles received a
sequence of tests to establish the level of emissions produced by each vehicle in its as-
received condition.

after the as-received tests. This examination was conducted to identify vehicle engine
parameters and components that were malfunctioning as a result of misadjustments or
intentional disabling actions, particularly to the emission control system. Procedures
and specifications for the inspection were conducted as delineated in the appropriate
service manual or as specified by the manufacturer's representative. Engine settings
(e.g. timing, choke, idle rpm and CO) that were found to be misadjusted were corrected
at this time. Disabled vehicle components such as disconnected hoses, lines and wires or
loose fittings were also repaired.
Engine components that were identified during the inspection as faulty due to
deterioration or as a result of production defects, were not corrected at this time but
were termed "defective" and noted for later repairs. However, defective emission
control components which would affect proper engine settings (e.g. idle stop solenoid)
were corrected.
Vehicles that received corrective maintenance during the inspection were
subjected to another sequence of tests. Chrysler and Ford vehicles found to have no
alterations or maladjustments, including idle rpm and CO settings, did not receive the
after adjustment test sequence. Because the idle rpm and CO inspection procedures for
General Motors vehicles require certain engine adjustments, each of these cars received
a test sequence after the inspection, regardless of their as-received condition.
Each vehicle received an emission component function check after the
Maladjustment and Disablement Inspection and any subsequent tests. During this
inspection, the operational efficiency of each separate component in the emission
control system was functionally evaluated according to procedures specified in the
appropriate service manual. A manufacturer's representative was also utilized in some
.- cases to assist in this inspection procedure. Problem areas were identified and noted on
an Emission Component Function Check Sheet for later repair.
Upon completion of both the Emission Component Function'Check and the
Maladjustment and Disablement Inspection, all defective engine parameters and
2-9
-------
malfunctioning emission control components were repaired. Each maintenance action
was performed according to shop manual procedures with the approval and guidance of a
manufacturer's representative. A full sequence of tests was performed immediately
following repairs to provide data on the emission related effectiveness of the maintenance
actions. FTP emission results were calculated as soon as possible for review by the
manufacturer's representative and the EPA. In most cases the test vehicle passed or
nearly passed the FTP. In those cases where emissions remained substantially above
federal standards, further action was required. Additional work on these vehicles was
determined jointly by the manufacturer's representative and the EPA. Any such
additional action was followed by a retest of the vehicle.
Following testing and the resolution of any subsequent problems, each
vehicle's catalyst was removed and replaced with a bypass unit equipped with a baffle
large enough to simulate normal catalyst back pressure. Since exhaust system pressures
vary from car to car, a separate bypass and baffle unit was constructed for each vehicle.
A full test sequence was then performed. After completing this sequence the bypass unit
was removed and a new catalyst was installed. New catalysts were preconditioned with
a minimum of 50 miles of driving before the test vehicles received a final test sequence.
Vehicles were returned to their owners upon completion of tests with a full tank of gas.
2.5 VEHICLE TEST FACILITY AND EQUIPMENT
The ATL test facility and associated equipment used for this work effort are
located at 10862 Metro Court, Maryland Heights, Missouri. This is a permanent facility
located just outside the St. Louis city limits.
This work effort was performed under a pre-existing contract to provide
additionaltesting capabilities for the Environmental Protection Agency. As a result,
facility and equipment check-in procedures .were performed at the beginning of the
contract in 1977 and periodically rechecked by representatives of the EPA.
2.6 LABORATORY TEST PROCEDURES
2-10
-------
Each vehicle received a prescribed sequence of test and inspection proce-
dures during the course of the work effort. These procedures and others associated with
the conduct of the program include the following:
Vehicle Preparation
Vehicle Preconditioning
Federal Test Procedure
Highway Fuel Economy Test
Federal Short Cycle
Two Speed Idle Test
Federal 3-Mode Test
After Test Procedure
Maladjustment and Disablement Inspection
Emission Component Function Check
Emission Component Repair
Determination of Failure
Catalyst Bypass Fabrication Procedures
Test Vehicle Depreparation
Details on these tests and procedures are presented! in the following sections.
2.6.1 Test Vehicle Preparation Procedures
All nine vehicles selected for testing received a uniform series of preparation
procedures to maintain standard testing conditions and to avoid possible vehicle
malfunctions. Transmission and oil fluid levels were checked and filled if found to be
low. Radiators and exhaust systems were also examined for. leaks prior to final
acceptance into the program. A fuel lead test was performed to establish the amount of
lead in the as-received fuel and to provide additional data when evaluating catalyst
efficiency.
Test procedures were performed in the laboratory at a location
2-11
-------
separate from the soak and emission test areas. Upon acceptance into the program, as-
received fuel was drained from the test vehicle's tank through a pump system connected
to the tank filler neck or the supply line to the engine. During draining operations, two
one-pint samples were collected and made available for analysis by the EPA and the
vehicle manufacturer. The tank was then refilled to 40% capacity with Indolene clear
fuel.
Snow tires and tires found to be severely worn were rotated to prevent their
use on the drivewheels. If the front and rear tires could not be exhanged, suitable
substitutes were acquired. Tire pressure on the drivewheels was also adjusted to 35 psi
for all test vehicles.
2.6.2 Vehicle Preconditioning Procedure
Test preconditioning for each vehicle included adjustments to the canister
system and a brief, 10-minute driveability evaluation. Residual fuel in vehicle canister
systems can affect fuel economy and exhaust emission tests as ungauged quantities of
gasoline are injected from the canister into the vehicle engine. To avoid such masking
effects, the canister systems on all test vehicles were either disconnected or rerouted
through a prepurged "slave" canister containing little or no fuel. The configuration of
emission control systems in Chrysler and General Motors vehicles required the install-
ation of slave canisters to assure optimum test results while canisters on Ford vehicles
were more accurately controlled by disconnecting the systems entirely.
An EPA driveability evaluation was performed prior to each soak period.
This evaluation was conducted to purge remaining as-received gasoline in the fuel system
and to provide test personnel with adequate advance knowledge of vehicle operating
"characteristics. The driveability test consisted of a five point rating (excellent, good,
fair, poor, fail) for vehicle performance during three operating phases: constant speed,
acceleration from idle and restart after shut-down. Each of the five ratings used during
the evaluation are defined as follows:
2-12
-------
Excellent - indicating no trace of undesireable elements (smooth, even
responsive).
Good - indicating a slight trace of an undesireable element (initial
unevenness, roughness, hesitation, quickly overcome).
*.
Fair - indicating an undesireable element exists yet realibility is
maintained (only intermittent misfire, surging, hesitation).
Poor - indicating an undesirable element exists which affects
reliability or driver confidence (steady misfire, roughness,
lack of power, response).
Fail - indicating extremely unreliable, possible unsafe conditions
exist (frequent stalling, die-outs on acceleration, lack of
throttle response).
General acceleration, cruise and idle quality were evaluated according to the'
rating system during the constant speed phase. During the acceleration from idle stage;
the quality of acceleration during quarter, half, two-thirds and three-quarter throttle
was rated. The restart phase was conducted after a ten minute engine-off period and
includes an assessment of idle quality and the duration of crank time.
2.6.3 Federal Test Procedure (Mass Exhaust Emission Test)
The Federal Test Procedure was performed in accordance with procedures
specified in 40 Federal Register 126. Preconditioning requirements for this test include
a 12 to 24 hour soak period in an area with an ambient temperature between 20 and 30
degrees Centigrade (68 to 86 degrees Fahrenheit). Each vehicle remained stationary
while soaking with the ignition in the unlock position and the transmission in neutral.
Doors were unlocked and the window on the driver's side was rolled down.
None of the nine vehicles acquired for this work effort received those
segments of the FTP which deal with evaporative loss measurements. Consequently,
following the soak period, test vehicles were moved to the dynamometer for the mass
exhaust emission segment of the FTP.
Before the test vehicle was placed on the dynamometer and secured,--the
proper inertia weight and load adjustments were set. During testing, the vehicle hood
f
remained open and a cooling fan was placed in front of the engine approximately six to
2-13
-------
twelve inches from the vehicle grille.
The Federal Test Procedure consists of three segments: the cold transient
stage, the cold stabilized stage and the hot transient stage. Sampling during the initial
cold transient portion was begun simultaneously with engine crank. This phase continued
for 505 seconds at an average speed of 25.6 miles per hour over a cumulative roll
distance of 3.59 miles. At the 505 second point, the exhaust sample was diverted from
the first sample bag of the CVS to the second. This marked the beginning of the cold
stabilized portion of the test. This segment covers 3.91 miles at an average speed of
16.0 miles per hour. Its duration is 869 seconds. At the end of this phase the engine was
stopped, sampling was terminated and the vehicle was soaked on the dynamometer for
ten minutes. After soaking, the vehicle was restarted and sampling was switched to a
third CVS bag for 505 seconds at an average speed of 25.6 miles per hour. CVS sample
and background bags were analyzed within ten minutes after completion of each phase of
the test.
2.6.4 Highway Fuel Economy Test Procedure
The Highway Fuel Economy Test consists of vehicle operation on the
dynamometer "over a 10.2 mile, 765 second driving schedule with the vehicle in a
warmed-up condition. Before testing was begun, each vehicle was driven at 50 mph on
the dynamometer for three minutes. Within one minute of the end of the cruise period,
the vehicle was brought to idle and the test begun. During the test, CVS dilute exhaust
was diverted into a sample bag over the entire driving schedule. Sampling was
terminated at the end of the schedule and the content of the sample bag was analyzed
for HC, CO, CO, and NO content. Load settings, inertia weights and vehicle speed
o X
tolerances for the HFET are identical to those used for the Federal Test Procedure.
2.6.5 Federal Short Cycle Test
The Federal Short Cycle Test is a nine-mode CVS test consisting of vehicle
operation over a 125 second driving schedule. Cumulative roll distance Is 0.7536 miles.
-------
Each mode and its duration are described below.
MODE DURATION OF MODE (sees)
1. 0-16 mph acceleration 6
2. 16-29 mph acceleration 23
3. 29 mph cruise 10
4. 29-37 mph acceleration 18
5. 37-42 mph acceleration 4.5
6. 42-37 mph acceleration 2.5
7. 37-20 mph deceleration 32
8. 20-0 mph deceleration 7.5
9. Idle 21.5
Total seconds 125.0
Inertia weight, horsepower loads and manual transmission shift speeds are the
same as those used during the Federal Test Procedure.
The Federal Short Cycle was preceded by a six minute preconditioning period
comprising a three minute soak with the engine off and a three minute idle (in neutral)
period. During preconditioning the engine compartment remained open with the
auxiliary cooling fan on. Total emissions over the full driving Sjchedule were collected in
one sample bag and analyzed within five minutes after the end of sampling.
2.6.6 Two Speed Idle Test
Raw tailpipe samples from vehicles operated at high idle and curb idle were
analyzed during the Two Speed Idle Test. This brief evaluation was preceded by a six
minute engine-off and. a three minute idle period. At the end of the six minutes, the
vehicle was operated in neutral for a maximum of three minutes at 2500 rpm and then at
curb idle. Exhaust emissions were analyzed at each speed after rpm and analyzer
outputs for CO, HC and NO had stabilized for a minimum of 30 seconds. Tests were
X
conducted with the vehicle hood open and the auxiliary fan on.

-------
2.6.7. Federal 3-Mode Test .
This test is comprised of three steady state modes performed with the
dynamometer loads set to simulate the average power (for all light duty vehicles)
occuring at each of the three speeds during an FTP. The 3-Mode Test is preceded by a
six minute (3^1 minute engine-off, 3+^1 minute idle) preconditioning period performed
with the hood open and the cooling fan on. Following preconditioning, the vehicle was
operated for a maximum of three minutes at high cruise (52 mph) with the inertia weight
set at the minimum level. The specified dynamometer horsepower was set for each
speed during the stabilization period. Equilibrium of vehicle speed and the CO, HC and
NO readings were maintained for 30 seconds before emissions were recorded. This
X .
procedure was repeated for the low cruise (25 mph) and idle modes. Since actual
horsepower was used for this test, additional dynamometer coast down calibrations at 25
and 52 mph were performed.
2.6.8 After Test Procedure
Basic engine parameters were measured after each test sequence to further
document test conditions. These parameters consisted of; basic ignition timing, dwell (if
applicable), idle speed, undiluted idle CO and HC. These measurements were performed
according to procedures outlined on the emission data sticker.
2.6.9 Maladjustment and Disablement Inspection
This inspection consisted of a step-by-step evaluation of separate engine
systems and their components to determine if each was functionally intact and complete.
During the course of the examination the induction system, carburetor and fuel system>
ignition system, EGR, air injection, PCV, exhaust system and evaporative control system
were inspected for proper settings and system alignment. Disconnected hoses, lines and
wires; missing or poorly fitted components were noted and repaired as part of the
procedure. Maladjusted engine parameters such as timing, choke and idle rpm settings
were also examined and corrected.
2-16
-------
Parts which were judged to be deficient due to wear or manufacturer error
were not corrected at this time but were addressed during the tune-up and repair
segment of the work effort. Those vehicles which received corrective maintenance
during this procedure were retested to provide data on the level of emissions produced by
high mileage vehicles with properly adjusted engine systems operating with an average
number of worn or defective components.
2.6.10 Emission Component Function Check
The Emission Component Function Check consists of a complete physical
examination of each operating component in the emission control system. Unlike the
Maladjustment and Disablement Inspection where engine systems are examined only to
see if each is functionally intact and properly adjusted, this evaluation involves a more
detailed systematic determination of the operational efficiency of separate components
within the emission control system. The inspection was performed using guidelines and
procedures outlined in the appropriate service manual or as specified by a manufacturer's
representative. Inspection procedures generally consisted of:
1. Identification of component (e.g. idle enrichment delay solenoid on
Chrysler vehicles)
2. Isolation and observation of operation (i.e. length of time solenoid was
activated)
3. Comparison with manufacturer specifications (i.e. 30 to 40 seconds)
Components found to be malfunctioning were noted on the Emission
Component Function Check Sheet and corrected during the Emission Control Component
Repair segment of the program.
2.6.11 Emission Control Component Repair
The Emission Control Component Repair Procedure was performed after the
Emission Component Function Check and consisted of the repair or replacement of
malfunctioning and defective components identified during previous inspections. All
repairs performed at this juncture of the work effort were recorded in the action
column of the Emission Component Function Check Worksheet. In most cases,
2-17
-------
maintenance was performed by ATL mechanics with the assistance and guidance of
manufacturer's representatives. All replacements were made with the same types of
parts originally used by the manufacturer.
Replaced parts were securely tagged and sent to the Environmental Protec-
tion Agency's laboratory in Ann Arbor, Michigan. Each tag contained the following
information:
1. Name of part, including the part number (if applicable)
2. Vehicle number
3. Reason for presuming defect or other problem
4. Method for determining defect or other problem
5. Additional comments (if any) on operation, diagnostics involved, diffi-
culty involved in obtaining replacements, or any other points that were
of future interest in this area.
2.6.12 Determination of Failure
After completing the preceding inspection and repair procedures, most
vehicles were able to pass or nearly pass the Federal Test Procedure using the following
standards.
Vehicle Year CO HC NO
1975 & 1976 15.0 1.5 3.1
1977 15.0 1.5 2.0
Vehicles with continued high emission levels were evaluated further to
determine the source of emission control system failures. This evaluation was performed
jointly between the EPA and the manufacturer. Because each of these vehicles already
received a tune-up, including .corrective maintenance of disabled or malfunctioning
emission control components, suspected sources of emission control failure were
generally limited to major: engine components (e.g. distributor) although previously
undiscovered malfunctioning emission control components were sometimes identified
during the re-evaluation. Most corrective maintenance actions were follo'wed by a retest
2-18
-------
of the vehicle unless otherwise instructed by the Project Officer.
2.6.13 Catalyst Bypass Fabrication Procedures
Following the completion of repairs and the resolution of any additional
emission control system malfunctions, each vehicle received a series of two test
sequences designed to provide data on catalyst efficiency. The first sequence was
performed after the as-received catalyst had been removed and replaced with a catalyst
bypass. This unit was constructed to create a level of exhaust system backpressure
comparable to that generated by the catalyst. Actual catalyst backpressure was initially
determined by gauging stabilized pressure levels generated upstream to the as-received
catalyst at a 60 mph cruise speed. After finding this pressure level the catalyst was
removed and replaced with a stock tailpipe repair section (approximately 16 to 24 inches
long) fitted with a circular plate or baffle at one end. The backpressure created by this
unit was then adjusted by drilling a series of half inch diameter holes in the baffle until
the pressure created by the bypass unit at 60 mph was within two inches H^O of the
Lf
actual catalyst backpressure. Because exhaust system configurations and pressures vary
from vehicle to vehicle, a separate bypass unit was constructed for each vehicle tested.
Following a full sequence of tests, the bypass unit was removed and replaced
with a new catalyst. After 50 miles of preconditioning, the vehicle was again tested
before being returned to its owner. All as-received catalysts were tagged and delivered
to the EPA for further inspection.
Z.6.14 Test Vehicle Depreparation
Before a vehicle was returned to its owner the following procedures were
performed.
1. Tires were rotated to the same configuration as received at the
laboratory and tire pressures were adjusted to their original levels.
2. Test vehicle "fuel tanks were refilled to full capacity.
3. Visual checks were performed to assure that the general status of the
vehicle was the same as when it was brought to the laboratory.
2-19
-------
2.7 DATA PROCESSING PROCEDURES
Accumulated raw test data and associated materials received a systematic
review of each test point in the work effort from initial generation to final processing.
These data accumulation and review procedures are described below.
2.7.1 Data Collection
Emission test procedures and laboratory conditions were monitored and
controlled through the use of strip chart recorders. These units provided a constant
read-out of data and also served to document test activities for later review. Test
parameters registered on the recorders included emission analyzer outputs, wet and dry
bulb measurements of air directed to the front of test vehicles and dilute exhaust stream
temperatures. Driver/vehicle perfomance traces were also documented on a strip chart
recorder and included speed calibrations and subsequent calibration checks performed
before and after each test.
A NOVA 2 minicomputer was utilized to collect and integrate CVS sample
and background bag emission data. Speed/time profiles were also generated for each
test schedule by the computer and produced on the driver/vehicle performance trace. In
addition to these functions, the computer totalized and recorded CVS mass pump
revolutions during each exhaust emission test segment.
Movement of each test vehicle through segments of the work effort was
controlled and documented through various raw data sheets. All data forms were
collected in test packets which were assigned to each vehicle prior to testing. As testing
progressed, relevant sheets were completed, signed and returned to the packet by the
appropriate technician. Included in the packet were: all raw data sheets used to identify
the vehicle, the vehicle exchange agreements, the completed vehicle owners question-
naire, raw data sheets used during tests, analyzer strip chart recordings, computer
system sheets and punch tapes and all appropriate temperature strip chart recordings.
Laboratory personnel were also furnished a form indicating the daily test
2-20
-------
schedule including the order each vehicle was to be tested and the estimated duration of
each test segment. Preconditioning personnel were also furnished with a similar
schedule indicating the time each vehicle was to be placed in soak.
2.1.2 Data Review and Editing
Vehicle packets were reviewed for completeness, accuracy and compliance
with temperature and speed tolerances on a test by test basis. This review was
performed as soon as possible after each test to allow an appropriate solution to any
problems that might arise. The test packet was reviewed a second time after all tests
had been completed. When practical, this was performed before the vehicle was released
to the owner. After solving any remaining discrepancies, the completed packet was
forwarded to the data processing department.
Data processing procedures included an additional review of packet contents
by personnel not directly involved in the original tests. Following this, data from the on-
site NOVA 2 minicomputer and raw data sheets were combined into a single punch tape
which was input to an offsite, time-share computer. The combined information was
subsequently listed back out and manually proofread against the original input to detect
errors introduced through keypunch operations or transmission difficulties. When obvious
computer errors had been resolved and corrected, a computerized edit program was
applied to the data. The program subjects each entry to a test of reasonableness. If
recorded information fails to fall within a predetermined range, the computer indicated
the presence of a possible error and identified the area requiring additional investigation.
Any discrepancies found to exist at this stage were resolved either through further
clarifying information from test personnel, reference to test records or through a
.complete retest of the vehicle.
As soon as all problems were resolved, the data was reduced and printed out
for a final review before the test was declared valid. When this process was completed,
the data was delivered to the EPA in the form of interpreted 80 column punch cards
2-21
-------
along with the completed data packet.
2.7.3 Calculation of Test Results
2.7.3.1 Federal Test Procedure Emission Data - Mass emission test results were
calculated using equations specified in 40 Federal Register 126. Fuel economy data for
this test was calculated using the carbon balance equation and reported in grams per
mile for CO, CO.,, HC and NO .
u X
2.7.3.2 Highway Fuel Economy Test - Exhaust emission results for this test were
calculated using Federal Register equations and a distance constant of 10.242 miles per
test. Fuel economy was calculated using these mass emission results and the carbon
balance equation.
2.7.3.3 Federal Short Cycle - Results of the Federal Short Cycle Test were calculated
using Federal Register equations and a distance constant of 0.7536 miles per test.
2.7.3.4 T\vo Speed Idle Test - Emission results for this test are comprised of tailpipe
concentrations and are reported as measured.
2.7.3.5 Federal 3-Mode Test - Emission results from this test are also comprised of
undiluted tailpipe concentrations and are reported as measured.
2-22

3. RESULTS
The tables on the following pages present the results of the Federal Test
Procedure Mass Emission tests at the various stages of the testing sequence. Also,
presented are averages for each of the manufacturer's and for the entire nine vehicles.
Averages may be somewhat distorted as the results on two of the Ford vehicles indicates
that the converters may have been significantly obstructed. This is indicated by the
reduction in CO and HC emissions achieved by removing the converters and installing the
bypass. These converters are now being subjected to a thorough analysis under a
separate EPA contract. The results of the analysis will be detailed in a report entitled,
"REPORT FOR WORK EFFORT #3, CONTRACT NO. 68-03-2693 - CHARACTER-
IZATION OF NINE HIGH MILEAGE CATALYTIC CONVERTERS FOR EPA".

Pass-outs are defined as restart from "off idle" stall
Die-outs are defined as restart from stall at idle
The codes for idle, acceleration and cruise quality are defined as
follows:
E - Excellent - No trace of undesirable elements (smooth, ^even, responsive)
J-ii
-------
G - Good - Slight trace, small indication of an undesirable element
(initial unevenness, roughness, hesitation, quickly overcome)
F - Fair - Undesirable element exists yet reliability is retained (only
intermittent misfire, surging, hesitation)
P - Poor - Undesirable element exists which affects reliability or
driver confidence (steady misfire, roughness, lack of power,
response)
U - Fail - Extremely unreliable, possible unsafe conditions exist
(frequent stalling, die-outs on acceleration, lack of
throttle response)
The Constant Speed Phase, Acceleration from Stop Phase, and the Restart
Phase are performed during the ten minute preconditioning drive. The
Cold Start and Idle Phase and the Drive-Away Phase are performed on the
