ABSTRACT
A comprehensive exhaust emission test program on properly maintained
and used 1972 through 1974 model-year vehicles was performed on 31 classes
of vehicles in the St. Louis, Missouri metropolitan area and on 22 classes
of 1972 and 1973 model-year vehicles in the Los Angeles metropolitan area to
determine if vehicles "in-use" continued to meet applicable exhaust emission
standards. This study was conducted and data forwarded to the United States
Environmental Protection Agency (EPA), Office of Mobile Source Air Pollution
Control, for use by the Administrator of the Environmental Protection Agency in
order that the Administrator may fulfill his obligations as defined in Section
207(c)(1) of the 1970 Clean Air Amendments.
Vehicles were randomly selected; inspection and restorative maintenance
were performed; and emission tests were conducted in accordance with EPA certi-
fication test procedures.

1. INTRODUCTION
The Clean Air Amendments of 1970, which became law on December 31,
1970, required all automobile manufacturers to warrant the maximum emission
levels of their vehicles beginning with the 1972 model year. The emission
levels of the vehicles are not to exceed the established emission standards
for 50,000 miles or five years, whichever occurs first. Furthermore, the
Clean Air Amendments established the mechanism requiring manufacturers to
rectify those classes of in-use vehicles that do not conform to air pollu-
tion requirements. Referencing Section 207(cHl) of the Clean Air Amend-
ment: "If the Administrator determines that a substantial number of any
class or category of vehicles or engines, although properly maintained and
used, do not conform to the regulations prescribed under Section 202, when
m actual use throughout their useful life (as determined under Section
202(d), he shall immediately notify the manufacturer thereof of such non-
conformity, and he shall require the manufacturer to submit a plan for
remedying the non-conformity."
The purpose of this program was to measure the emission levels from
a statistically valid sample of 1972, 1973 and 1974 properly maintained and
properly used light-duty vehicles. Testing was conducted in five metropolitan
cities across the United States. AESi performed testing in St. Louis,
Missouri, and Los Angeles, California. Olson Research Laboratories, Inc.
conducted testing in Detroit, Michigan; Philadelphia, Pennsylvania; and
Atlanta, Georgia. Thirty-one vehicle engine classes were tested; two
1972, twenty-one 1973, and eight 1974 model-year engine classes comprised
the vehicles that were tested under this program. The 1972 and 1973 model-
year engine classes received restorative maintenance based upon inspection of
each vehicle's engine and emission control devices. The 1974 model-year
vehicles were inspected but less extensive restorative maintenance was per-
formed. The emission data generated from this program along with supporting
documentation have been provided to the United States Environmental Protection
Agency, Office of Mobile Source Air Pollution Control, for use by the
-------

Administrator of the Environmental Protection Agency in order that the
Administrator may fulfill his obligations as defined in Section 207(c)(1)
of the Clean Air Amendments of 1970.
This report is a narrative summary by vehicle engine class and test
site of the Vehicle Sampling, Inspection and Maintenance, and Exhaust
Emission Testing performed in this program.
Figure 1.1-1 lists the engine classes tested by make, engine displace-
ment, and number of carburetor Venturis. The three-digit class number used
throughout this report consists of one digit for the model year with the

2. TECHNICAL DISCUSSION
2.1 PROGRAM OBJECTIVE
The overall objective of "FY73 In-Llse Compliance Testing
Program for Light-Duty Vehicles" was to procure properly maintained and
used 1972, 1973 and 1974 vehicles, to perform restorative maintenance, and
to emission test these vehicles in accordance with certification testing
procedures. The statistical data developed under this program along with
supporting documentation was provided to the United States Environmental
Protection Agency, Office of Mobile Source Air Pollution Control, for the
Administrator of the Environmental Protection Agency in order that he may
fulfill his obligations as defined in Section 207(c)(1) of the Clean Air
Amendments of 1970.
-------

2.2 VEHICLE PROCUREMENT
The objective of this activity was to procure randomly selected
consumer-owned 1972, 1973 and 1974 automobiles of the appropriate vehicle
class to determine their eligibility for emission testing and to make all
necessary arrangements with the vehicle owners enhancing their participation.
To ensure comparable emission data among all contractors for the In-Use
Compliance Testing Program, the Environmental Protection Agency (EPA), Office of
Mobile Source Air Pollution Control, established vehicle procurement guide-
lines. The overall management, determination of vehicle eligibility, docu-
mentation of participation, disposition of test vehicles, and award of
owner incentives were performed according to the following procedures.
2.2.1 Test Vehicle Selection
Magnetic tapes containing the names of candidate test vehicle
owners were provided by EPA for the St. Louis, Missouri, and Los Angeles,
California, test sites. These tapes contained a random list of admissible motor
vehicles by vehicle engine class. For the 1972 and 1973 model-year vehicles,
one tape was provided for St. Louis and one tape for Los Angeles. For the
1974 model-year engine classes, the tapes were provided twice for six of the
eight classes and once for the other two. The 1974 model-year vehicles and
Class 309 (engine class 09, model year 1973) were not tested in Los Angeles,
California. Table 2.2-1 lists the engine classes and the number of vehicles
that were tested at each test site.
To ensure that vehicle sampling was as random as possible, vehi-
cles were procured in the order listed on the tapes. That is, for the first
vehicle contained on the list every effort was made to contact the vehicle
owner, determine vehicle eligibility, and schedule an appropriate time with
the vehicle owner for emission testing the vehicle. If the vehicle was
rejected for any reason, then the next vehicle owner on the list became
eligible to participate. In other words, if the first 20 vehicle owners
on the list were contacted and only one of the 20 participated, then the
next 19 names on the list became eligible to participate in the program.

2.2.2 Contact with Vehicle Owners in Sample
A letter from AESi and an EPA cover letter were sent by
certified mail to registered vehicle owners in the order they appeared
on the magnetic tape printout. The AESi letter and EPA cover letter are
shown in Figures 2.2-2 and 2.2-3. Letters were mailed in stages by
vehicle class in order to minimize the time between the mailings and the
initial telephone or personal contact. After a mailing was completed,
vehicle procurement technicians obtained telephone numbers, when listed,
for the subsequent follow-up telephone contacts to determine their willing-
ness and eligibility for participation in the program. When telephone numbers
were available, a minimum of four attempts were made to contact the vehicle
owner. The calls were spaced at various times of the day, evening, and
weekend. If four telephone attempts were not productive in making contact
with the vehicle owner, then four personal contacts were attempted. For
vehicle owners with unlisted telephones, a maximum of four personal con-
tacts were made. Often certified mail was returned to AESi as undeliverable
or refused by the party to whom addressed. In these cases, a second mailing
was made to the vehicle owner by first-class mail in a second attempt to
contact the vehicle owner.
In Los Angeles, California, 33.1 percent of the vehicle owners
had unlisted telephones. In St. Louis, Missouri, 12.7 percent had unlisted
telephones. During the latter stages of the program, the number of personal
contacts which were needed approached a staggering magnitude. While the EPA
cover letter asked vehicle owners with unlisted telephones to call the
contractor, this message was almost always overlooked. To increase the
rate of vehicle owner contactsj AESi included a one-page attachment to
the introductory letter and EPA cover letter asking vehicle owners to please
call AESi collect. A copy of this supplemental letter is shown in Figure

Air pollution and its consequences continue to be a critical problem an
-nany major urban areas in the United States To investigate and combat this
problem, a number of programs are under way at all levels of government and
industry
The automobile continues to be a major contributor to urban air pollution,
Lind the Ifnited States government has since 1968, required new cars to meet
increasingly stringent air pollution emission standards. As required by the
Clean Air Act of 3970, vehicles now being manufactured must meet certain emis-
sion standards during their defined life of 50,000 [riles If these automobiles
fail to meet the standards, when properly maintained and operated, auto manu-
focturers may be required to recall these vehicles to correct their emission
control systems
The Environmental Protection Agency of the United States government has
been authorized to conduct a testing program to determine if 1972, 1973, and
1974 model vehicles are meeting these standards. About 4,500 vehicles will be
tested at five sites across the nation. Automotive Environmental Systems, Inc
(AESi) is responsible for securing and testing vehicles for the Environmental
Protection Agency in this area
A 1973 automobile registered in your name has been randomly selected for
testing If you are the original owner of this vehicle, please check the
vehicle identification information next to your name and address to make sure
that our records are correct If your vehicle meets certain eligibility
requirements, we are anxious for you to provide your car for testing Yout
vehicle will be operated under normal driving conditions as simulated on a
dynamometer, and your vehicle's exhaust emissions will be measured and analyzed.
Normally, wc will need to keep your car for about two and one-half days
Vehicles eligible for testing must meet the following requirements, which
.«rc intended to provide a sample of "typical" 1973 automobiles
1 The vehicle has accumulated less than 50,000 miles
2 The vehicle has had oil and oil filter changes at the intervals
specified in the owner's manual
3 The vehicle has been operated on unpaved roads less than 50% of
the time
4 The vehicle has not been entered in competitive speed events
5 The vehicle has not been used to transport heavy loads for which
it was not designed

7 The vehicle has not been involved in an accident which damaged
the engine, frame, or gas tank
8 The vehicle or engine has not been altered by the installation of
exhaust headers, performance carburetor components, a performance
camshaft, performance ignition equipraent, or modified exhaust
systea components
9 The engine or carburetor has rot been disassembled or serviced
internally
While your vehicle is in our custody, it will be fully covered by our
collision, liability, and comprehensive insurance In addition a new loan
car will be provided for your use, and a number of incentives will be awarded
if your car goes through the complete test cycle These incentives include
1 A J50 U S Savings Bond
2 An engine tune-up, if required
3 A new set of spark plugs
4 A full tank of gas
5 A mechanical inspection report on the overall condition of your
vehicle
6 A certificate of participation
Jf, for some reason, your car is transferred to our custody, but is
determined unacceptable for testing, you will receive incentives for partial
participation These incentives are a $10 cash award, use of a loan car
while we have your cot, and a mechanical inspection report detailing the
reason(s} why your vehicle was not accepted for testing
A member of our staff will telephone you within the next few weeks to
answer any questions you may have about the test program, and to determine if
you will allow your vehicle to be tested, if it is eligible. If you are con-
cerned about the treatment your car will receive during testing, we will be
happy to give you a tour of our test facility
We at AESi consider this testing program to be a crucial part of con-
trolling air pollution The problem of air pollution cannot be solved without
the support and participation of concerned citizens. We sincerely hope that
you will be willing to let your vehicle be tested, and we will greatly
appreciate your contribution to the success of our program
Sincerely,
Robert Rederer
Procurement Supervisor

A Message to the Car Owner
The U.S. Environmental Protection Agency, in carrying out the
Clean Air Act, has contracted with competent testing organizations to
make emission tests of certain specific 1973 model automobiles. The
purpose of these tests is to determine whether such vehicles, as a class
or category, meet Federal emission standards in actual use. The emission
test results from any individual car will be used by the EPA only in
combination with the test results from all other similar cars; the
outcome of the test on any individual car can not result in any enforce-
ment action against the owner of the car.
The enclosed letter to you, from one of these testing organizations,
explains this project in detail, and asks to test your car. The purpose
of this message is to urge that if at all possible you allow your 1973
model car to be tested in this program.
To assure valid results from this testing program, complete statis-
tical methods are used to select without bias from state registration
records the specific cars that will comprise the sample to be tested.
Your car has been tentatively selected in that process. Your participa-
tion in the test will represent a real and significant contribution to
the cause of Clean Air.
Please read the enclosed letter. You will note that it says that a
follow-up will be made by phone. Should you have an unlisted telephone
number, or if for any other reason it may be difficult for the testing
organization to reach you by phone, please call the number given in the
enclosed letter to arrange for your participation.

2.2-4. This added note proved very successful and reduced the number of
personal contacts substantially. When vehicle owners were asked if they
read the message in the EPA cover letter about contacting the contractor,
they usually replied that they had not bothered to read the last paragraph.
To summarize the overall procurement activity, Table 2.2-2 lists the
results for the total program and by test site. Individual summaries by
test site and class are shown in Appendix A.
During contact with the vehicle owner, a vehicle procurement
specialist asked the vehicle owner a number of detailed questions. The
objective of the telephone call was to determine vehicle eligibility and
to reject unqualified vehicles by telephone rather than in the field or
at the laboratory. The list of eligibility requirements used to question
vehicle owners (and recorded on the telephone contact control sheet shown
as Figure 2.2-5) for the 1972 and 1973 model-year vehicles contained the
following items:
1. The vehicle was a 1972 or 1973 model year and
one of the specified engine classes.
2. The vehicle had not accumulated more than 50,000
miles and would not accumulate more than 50,000 miles
by the time the vehicle was brought in for testing.
3. The vehicle owner was the original owner.
4. The vehicle had the oil and oil filter changed as
specified in the owner's manual.
5. If the answer to Item No. 4 was yes but the vehicle
owner did not have proof, would he sign an affidavit?
6. The vehicle had been operated on unpaved roads less
than 50 percent of the time.
7. The vehicle had not been used to transport heavy
loads for which it was not designed.
8. The vehicle had not been entered in competitive
speed events.

DEAR VEHICLE OWNER:
While the enclosed introductory letter states that AESi
personnel will be calling your shortly, this will not be
possible if you have an unlisted telephone number. Our past
experience shows that about 70 percent of the telephones in
Los Angeles County are not listed.
If you have an unlisted telephone number, we would veTy
much appreciate your calling us COLLECT at (714) 897-0331. Our
contractual requirements with the Environmental Protection Agency
make it necessary that we contact all vehicle owners who receive

which damaged the frame, engine or gas tank.
11. The carburetor had not been removed, replaced
or rebuilt.
12. The vehicle's engine had not received major main-
tenance (rings, valves, etc.).
13. The VIN on AESi's magnetic printout list agreed
with the VIN on his vehicle.
There were many instances where the registered owner of the candidate
vehicle was listed as a company, leasing firm, or car rental agency. In
these cases, the agent of the registered owner was contacted and asked for
permission to test the vehicle(s) in question. If the response was negative,
the vehicle was rejected. If the response was affirmative, the owner was
asked to provide a list of the vehicles with the "custodians'" names and
addresses. The list of "custodians11 was then used to update the computer
list. In the case of rented vehicles, the agency may have been located
within the sample area while the car itself was outside of the area. If
the car was not expected to return within a reasonable period, it was
rejected. Overall, for both test sites, 23.2 percent of the vehicles were
leased or non-privately owned.
2.2.3 Vehicle Pickup and Initial Inspection
During the telephone contact, a definite time was established to
inspect the vehicle in the owner's presence to further establish program
eligibility. The list of items inspected during vehicle pickup was the
following:
1. Inspect vehicle for damage to engine, frame or
fuel tank.
2. Examine exhaust system for damage or corrosion.
3. Check vehicle for trailer hitches, non-standard
tires, tire condition and suspension system.
4. Check that the VIN was the same as on computer
printout.
-------
2-15
5. Check for high performance modifications.
6. Check foT removal of emission control systems.
7. Check oil level and oil filter cartridge appearance.
8. Check that all drive belts are present.
If the vehicle passed this initial inspection, the owner ques-
tionnaire was completed and the affidavit signed if maintenance records or
oil and oil filter maintenance proof were missing. Test vehicle and loan
car forms were then completed and the test vehicle was brought to the
laboratory for inclusion in the program.
2.2.4 Vehicle Rejection
Appendix A summarizes vehicle procurement activities by test
site and vehicle engine class. The following discussion highlights common
causes for vehicle rejection. Item "e" of Appendix A (total number of
vehicles tested) includes only those tests accepted by EPA.
2.2.4.1 Owners Not Available to Contact: Contacting vehicle
owners in Los Angeles, California, was far more difficult than in St. Louis,
Missouri, for two reasons: (1) the greater number of unlisted telephones
nnd (2) the residents in the area being more transient. The initial mailing
to vehicle owners was by certified mail. When this letter was returned to
AESi because the vehicle owner refused to pick up the letter, a second letter
was sent by first-class mail. If a letter was returned to AESi because the
owner had moved and left no forwarding address, the vehicle was rejected.
If a second letter was not returned, and the vehicle owner did not have a
listed telephone number, a personal contact was made. In Los Angeles,
personal contacts were frequently not productive since people who answered
the door were very hesitant to even listen to the program details. However,
in St. Louis when personal contacts were made and a resident was found at home,
-------
2-16
about half of these contacts resulted in procurement of the vehicle
for testing. In general, personal contacts were non-productive in
both cities.
2.4.4.2 Owners Unwilling to Participate: When telephone
or personal contacts were made, the following are reasons for unwilling-
ness to participate:
1. Could "care less" about the program.
2. Thought the program was a waste of the tax-
payer's money.
3. The program would not do anything to clean
the air.
4. Did not have the time.
5. Would not let car out of their possession.
6. Would not let another mechanic work on their
car.
7. Rental and leased car agencies did not want
to be bothered with searching through their
files to locate consigned owner.
8. Company-owned cars would create a schedule
problem if in the program.
2.4.4.3 Sold Vehicles: Vehicles sold by the original
owner were a common cause for rejecting vehicles. Leased vehicles,
rental vehicles and company-owned cars contributed the greatest per-
centage of these vehicles. This was especially prevalent in St. Louis,
Missouri, during the latter stages of the program for the 1974 model-
year vehicles.
-------
2-17
2.2.4.4 "No Show" Vehicles: Very few vehicle owners failed
to participate in the program because they changed their minds or failed to
remember the scheduled appointment. Vehicle owners were telephoned one
or two days in advance, or immediately before the scheduled time, to remind
them of the appointment.
2.2.4.5 Vehicles Rejected in Field: The screening of vehicles
during the telephone contact reduced the number of field disqualifications
to very few. Vega Class 228 was a problem since vehicle owners usually did
not know if their car had a one- or two-barrel carburetor. The two-barrel
carburetor was a requirement for program participation. In St. Louis, the
largest single cause of vehicle rejection was the wrong engine type. Ford
vehicles manufactured with the 351 CID W (Windsor) engine or the 351 CID C
(Cleveland) engine caused a problem, since the vehicle identification number
(VIN) could not be used to determine the engine with which the vehicle was
equipped. The vehicle owner also seldom knew the difference between the two
engine types. As a result, a personal visit to the vehicle owner's home was
necessary for a visual inspection of the engine. The 351 C engine was difficult
to find.
2.2.4.6 Vehicles Rejected in Laboratory: Evidence of vehicle
tampering was the main reason for rejection of vehicles in the laboratory.
Evidence of tampering was more prevalent in Los Angeles than in St. Louis.
Vehicles equipped with EGR and Ford engine classes were most often tampered
with. Vacuum line rerouting, plugged vacuum lines, and distributor centri-
fugal advance springs of a lesser tension were common modifications found.
2.2.4.7 Vehicles Exceeding Mileage: In St. Louis, Missouri,
about 75 percent of the 1974 model-year vehicles rejected were due to the
-------
2-18
vehicles exceeding 12,000 miles. The 1972 and 1973 model-year vehicles
that were non-privately owned often exceeded 50,000 miles. Rejection of
privately owned 1972 and 1973 model-year vehicles for this reason seldom
occurred.
2.2.5 Vehicle Classes Difficult to Procure:
Vehicle classes in Los Angeles, California, difficult to procure
and reasons for this difficulty were as follows:
1. Class 228 - Chevrolet Vega. Many of these vehicles
were sold by original owner or the vehicle was not
equipped with the required 2-barrel carburetor.
2. Class 355 - Audi. This class required the vehicle
to be equipped with a manual transmission, and most
vehicles on the list were equipped with automatic
transmissions. Only manual transmission vehicles
were equipped with the exhaust emission control
system EPA desired to test.
3. Class 338 - Datsun. The list of registered vehicle
owners was a mix of 1972 and 1973 model-year
vehicles. Only the 1973 model-year vehicles were to be
tested. Vehicles owners sometimes did not know that
they had a 1972 model-year vehicle until they were con-
tacted by AESi. The vehicle was often sold to the owner
as a 1973 model-year vehicle.
4. Class 331 - Buick. Buicks were difficult to procure due
to the owners' resistance in allowing their cars to be
tested.
5. Class 351 - VW. Vehicle owners were resistant to par-
ticipate and required extra convincing before they would
allow their cars to be tested.
6. Class 356 - Ford. The owners were very resistant.
Vehicle classes in St. Louis, Missouri, difficult to procure
were as follows:
1. Class 228 - Chevrolet Vega. Many of these vehicles
were sold by the original owner or the vehicle was
not equipped with the required 2-barrel carburetor.
-------
2-19
2. Class 307 - Ford. This required separating the 351 W
from 351 C engines. The VIN on the tape printout did
not make this distinction.
3. Class 338 - Datsun. All vehicles on the list were
1972 model year. The program required testing of
1973 model-year vehicles.
4. Class 349 - Pontiac. Because of the exhaust emission
control system that EPA desired to test, the vehicle
had to be a 350 CID, manual transmission type. No
vehicles meeting these requirements were found.
5. Class 356 - Ford. Vehicle owners were resistant to
participating.
6. Class 412 and 414 - Ford. These classes required
separating the 351 W and 351 C engines. Class 412
vehicles were nearly impossible to find. Also, many of
these vehicles were leased and had been sold.
7. Class 416 - Cadillac. Vehicle owners were very resistant
to allowing their vehicles out of their possession.
Additional procurement difficulties were due to "short" vehicle
classes; that is, insufficient numbers of registered vehicle owners to con-
tact. Table 2.2-3 itemizes by test site and vehicle engine class the number
of vehicles required for testing, the number of registered vehicle owners on
the list, and the number of vehicles actually tested. Unfortunately several
of the "short" classes were difficult to procure for other reasons (see above).

2.3 VEHICLE INSPECTION AND MAINTENANCE
2.3.1 1972 and 1973 Model-Year Vehicles
Each vehicle's engine and emission control device were
inspected to determine component condition. The inspection of components
was based on the vehicle's current mileage and time since the vehicle
was purchased by the vehicle owner. Repair or replacement of a component
system was based solely on a competent mechanic's judgement of the condition
of a component/system (with the exception of filters and evaporative emission
canisters). If a component/system to be inspected was determined to not be
within the manufacturer's specifications, it was adjusted, repaired, or replaced.
In addition, a list of items to be inspected and restored regardless of the manu-
facturer's recommended maintenance interval included:
1. Ignition point dwell
2. Ignition points and condenser
3. Initial timing
4. Idle air/fuel mixture
5. Distributor cap and rotor
6. Ignition wires
7. Curb idle RPM
8. Exhaust control valve
9. Thermal reactors
10. Throttle and choke linkage
11. Tubes, hoses, fittings, and electrical connectors
12. Air cleaner element
13. Crankcase emission filter element
14. Spark plugs [mandatory)
15. Exhaust system
16. Radiator core
17. Air conditioner condensor core
18. Engine coolant level
19. Engine coolant specific gravity
20. Radiator pressure cap
21. Vacuum advance diaphragm (if leaking)
22. Mechanical advance adjustment (if specified by manufacturer)
23. Engine drive belts
24. Fast idle RPM (if specification given)
Appendix B summarizes by test site and vehicle engine class
the frequency of parts repair, replacement or adjustment. Table 2.3-1
summarizes by test site and vehicle engine class vehicles which showed
cylinder leakages of greater than 15 percent after oil had been introduced
into the cylinder to seal the leakage past the piston rings.

2.3.2 1974 Model-Year Vehicles
The emission control components of the 1974 model-year
vehicles were inspected based on each vehicle's current mileage. However,
no restorative maintenance or mechanical adjustments were performed except
as noted below:
1. Spark plugs (always replaced)
2. Exhaust system
3. Radiator core
4. Air conditioner condenser core
5. Engine drive belts
6. Engine collant level
7. Engine collant specific gravity
8. Radiator pressure cap
Appendix C summarizes by engine class the state of mechanical
tune the vehicles were m when emission tested. Table 2.3-2 summarizes the
number of vehicles that had "wet" cylinder leak-down tests that exceeded
15 percent.
2.3.3 Parts Maintenance Rates
Appendix B deals with 1972-1973 model-year vehicles and lists by
test site and vehicle class the frequency of parts and emission-related
systems that required maintenance and the type of maintenance performed.
For the 1972-1973 model-year vehicles, the frequency of parts failure rates
in descending order were: air cleaner element, fuel filter, crankcase
inlet air cleaner, ignition points, condenser, PCV valve and system, fuel vapor
inlet filter, ignition wires, distributor rotor, EGR system, radiator pressure
cap, distributor cap, A.I.R. system, carburetor choke and accelerator linkage,
and idle stop solenoid. For the 1973 model-year vehicles, the frequency of
maintenLnce required in descending order were: idle RPM, timing, idle CO,
vacuum advance, point dwell, centrifugal advance, points, radiator pressure
cap, exhaust gas recirculation system, coolant level, and coolant strength.
Appendix C lists the state of tune parameters, parts and condition of emission-
related systems for the 1974 model-year vehicles (on which restorative main-
tenance was not performed).

2.3.4 Original Equipment Parts Difficult to Obtain
Original equipment parts (OEM) were not difficult to
obtain. All parts were readily available and did not result in any
program delay. On one occasion, AESi did encounter difficulty obtaining
a distributor vacuum advance diaphragm for a Class 351 Volkswagen.
2.3.5 Vehicles Difficult to Perform Inspection and Maintenance
Vehicle classes difficult to perform inspection and main-
tenance on were:
1. Class 349
2. Class 351
3. All Ford engine classes
Items 1 and 2 listed above were difficult to perform IfJM
on because of engine and body configurations. This difficulty existed
because of the lack of adequate working space around the engine to perform
engine diagnostics. In general, all Ford Motor Company vehicles required
additional time due to (1) the nature of the emission control systems
and (2) the frequency of production changes forced the mechanics to spend
a great deal of time looking up calibration codes. Ford vehicles frequently
showed no evidence of tampering, but the engine configuration did not
-latch the specified calibration number. Also, AESi frequently encountered
calibration codes for which data was not immediately available.
-------
2-26
2.4 VEHICLE EMISSION TESTING
Exhaust emission tests were performed in accordance with
test procedures for gasoline-fueled light-duty vehicles in 37 Federal
Register 221, November 15, 1972, Part II, as corrected by Advisory
Circular 1-2, and as amended by 38 Federal Register 124, June 28, 1973.
The process through which each vehicle was tested is shown in Figure
2.4-1.
2.4.1 Preconditioning
Following inspection and maintenance procedures by AESi's
mechanics, the test vehicles were preconditioned over a 1-hour road
course in the immediate vicinity of the test laboratory. Figures 2.4-2
and 2.4-3 are maps of the preconditioning road courses for Los Angeles,
California, and St. Louis, Missouri. These road courses were selected
to allow vehicle operation at 55 mph, 45 mph, and residential speeds of
25 mph. Preconditioning was scheduled to avoid peak traffic congestion
and better ensure that the 32-mile road course would be completed in
about one hour.
Immediately upon completion of mileage accumulation, the
fuel tank was drained and the fuel system pressure checked. The fuel
tank line at the fuel pump was disconnected and plugged, and pressure
was applied to the evaporative emission line from the fuel system to
the vapor storage canister. The fuel system was pressurized with dry
nitTogen to fourteen inches of water pressure. The fuel system was
considered acceptable if the pressure loss was less than or equal to
2 inches water pressure in five minutes. Fuel system leaks were uncommon
during the performance of testing in this program. On several occasions
fuel caps were found to leak. However, test vehicle fuel caps were not
used during testing, and were replaced with properly functioning ones.

Following pressure testing of the fuel system, three gallons
of test fuel were added and the vehicle was driven on the emission
dynamometer for one Federal Test Procedure driving schedule. The vehicle
was then pushed to the soak area for 12 to 20 hours of cold soaking.
During the last hour of soaking the vehicle's fuel tank was
drained and refilled with temperature-conditioned test fuel to 40 percent
of the manufacturer's published tank capacity. Ambient and tank fuel
temperature was continuously monitored from this time until the end of
the emission test. The temperature of conditioned fuel in the vehicle's
tank was elevated from 60 - 2°F to 84 - 2°oF in 60 - 10 minutes. AESi did
experience operating difficulties with ambient temperatures during this
phase of testing. Spurious temperature fluctuations from laboratory per-
sonnel opening a door, or an eddy of warm air from the emission dynamometer
caused the ambient temperature recorded to exceed the 76-86°F temperature
limits. This, of course, resulted in a sizable number of voided emission
tests.
2.4.2 Exhaust Emission Test
The dynamometer was previously warmed up for 15 minutes at 30
mph with a non-test vehicle if the dynamometer had not been used during the
previous two hours. Dynamometer loading and inertia were set with a non-
test vehicle immediately before the test vehicle was pushed on the dyna-
mometer. Difficulties AESi experienced with exhaust emission test procedures
were with temperature recording during the emission test. At the beginning
of the program the recording thermocouple quite often reacted to warm air
currents from the vehicle engine, thereby exceeding the 86°F maximum. This
resulted in void tests until the problem was solved by shielding the fan to
keep stray air currents as far away as possible.
The vehicle was started from a cold start in accordance with
the vehicle owner's manual. Table 2.4-1 lists the cold start procedures
that were followed.

2.4.3 Vehicle Driveability
The following vehicle classes had poor vehicle driveability
characteristics during the cold portions of the Federal Test Procedure:
1. Class 228
2. Class 310
The small engine displacement combined with the cold engine made
following the driver's trace on the first acceleration very difficult.
After engine warmup, these two classes were no more difficult to drive
than any other vehicle engine class.

2.5.2 Constant Volume Sampler
The equipment described in this section was designed
and built in accordance with requirements stipulated in pertinent
issues of the Federal Register for performing vehicle emission tests
in accordance with the 1972 through 1975 Federal Test Procedures.
An AESi-designed and fabricated constant volume sampler was utilized
in each city. Each of these constant volume samplers featured a gas-
to-water heat exchanger and temperature control circuit allowing for
precise control of the sample temperature. Inlet pressure depression
was adjusted by a precision butterfly valve enabling inlet pressure
adjustments to within plus or minus 0.05 inches of water. Blower speed
was maintained at a constant 1,125 revolutions per minute by the use
of a constant speed motor. Blower revolutions were counted by the
use of a magnetic pickup and an electronic counter. All function controls
are pushbutton operated giving a confirming visual indication when
each particular function is being performed. Table 2.5-1 lists the

2.5.3 Exhaust Analysis Console (EAC)
The exhaust analysis consoles used during the performance
of this program were designed in accordance with specifications stipulated
in various Federal Registers for vehicle emission testing by the 1972
Federal Test Procedure. The instruments used in the exhaust analysis
consoles were the Beckman Model 315A or 315B Nondispersive Infrared
Analyzers (NDIR's) for the measurement of carbon monoxide and carbon
dioxide. The carbon monoxide instrument featured a stacked sample
cell configuration and three -range amplifier. The carbon dioxide analyzer
contained the standard 1/8 inch sample cell with a three-range amplifier.
Table 2.5-2 lists the performance specifications of the exhaust analysis
consoles.
A Beckman Model 400 Flame Ionization Detector (FID) was
utilized to measure total hydrocarbons. Each of the Model 400 Flame
Ionization Detectors was operated with a 40 percent hydrogen/60 percent
nitrogen fuel mixture and special capillary to minimize the oxygen
effect.
The Thermo Electron Corporation Model 10A Chemiluminescence
Analyzer was used for the measurement of NO and N0X. This instrument
was equipped with seven ranges from 0 to 10 through 0 to 10,000 ppm
NO. A thermal converter was employed to convert NO2 and other nitrogen
oxides to NO. A Thermo Electron Corporation Model 100 N0X generator
was added to each EAC unit in performing N0X converter efficiency determina-
tions in accordance with 38 Federal Register 124, Section 85.074-23.

the exhaust analysis console to record all instrument signal outputs.
Table 2.5-3 indicates the ranges used for each instrument.
2.5.4 Fuel Conditioning Cart
The AESi fuel conditioning cart used to condition test
fuel was of the same design and manufacture as those used by the
Environmental Protection Agency in the Ann Arbor facility. The fuel
conditioning cart was capable of maintaining a bulk fuel temperature of
60°F or less, and of transferring fuel from one tank to another. It
featured an internal fuel circulating mode to expedite gasoline tempera-
ture conditioning and to prevent temperature stratification within the
tank. The cart was fabricated in accordance with the National Electric
Code specifications for equipment operated in hazardous atmospheres.
2.5.5 Laboratory Standard Calibration Gases
Two complete sets of laboratory standard calibraton gases
were furnished to AESi. The contents of each cylinder were analyzed
and concentrations were assigned by the Office of Mobile Source Air
Pollution Control of the Environmental Protection Agency in Ann Arbor.
Each laboratory used the standard set of gases for defining the complete
instrument calibration curves and for subsequent assigning of values
to the day-by-day "working" gases. The laboratory standard gases and
their nominal concentrations are tabulated in Table 2.5-4.
2.5.6 Chassis Dynamometer

generator driven by the front roll to the CE-50 to operate the driver's
aid chart and facilitate calibration. Throughout the course of the
program the breakage of dynamometer belts delayed testing operations
since the dynamometer required a period of conditioning the belts and
then a calibration check. The St. Louis laboratory was particularly
plagued by this problem.
2.5.7 Miscellaneous Equipment
In addition to the equipment previously described, Varian
driver aids were utilized to provide driving schedules for the various
driving sequences performed during this program. An Autoscan ignition
analyzer, timing lights, tach-dwell meter, other tuneup equipment, and
small tools were used as necessary. To measure idle carbon monoxide
and hydrocarbons, a Horiba Mexa 300 dual range NDIR exhaust gas analyzer
was used. The nominal concentration ranges for this instrument are
0-2% and 0-10% carbon monoxide, and 0-400 ppm and 0-2000 ppm hexane
equivalents.
Precise weighing of propane recovery test cylinders was
accomplished using a Sartorius Balance which can weigh up to 2.2 Kg
with Class S weights which are traceable to the National Bureau of Standards.
For less precise measurement, an O'Haus Scale with an accuracy of - 50 mg
was used.
Absolute pressure was measured with a Meriam Model 310EF10
Mercury Manometer incorporating a 0.01 inch of mercury vernier scale
and a thermometer. Calibration is traceable to the National Bureau
of Standards and is within 0.009 inch of mercury throughout the working
range.
Temperature measurements were made with certified ASTM 64F
or 50F thermometers or pyrometers and thermometers calibrated against
the ASTM thermometers. Calibration is traceable to the National Bureau
of Standards.
-------
2-53
For calibration of the constant volume sampler, AESi used
Meriam Model 50 MC2-6SF and Model 50 MC2-4SF laminar flow elements.
Both of these instruments have calibration curves traceable to the National
Bureau of Standards. Moreover, these instruments have been operated in
series such that total measurement differences could be observed. These
differences are less than 0.5%.
Instruments used to monitor the laminar flow elements include
the temperature and pressure devices listed above plus inclined manometers
(Meriam Models 40GD10 and 40HE35) for determining the pressure drop across
the laminar flow element. The inclined manometers have calibrations which
are traceable to the National Bureau of Standards.

2.6 EQUIPMENT QUALIFICATION, CALIBRATION AND CROSS CHECK
This section describes in detail the qualification, calibra-
tion and cross check procedures utilized by AESi and EPA technical personnel
to ensure the generation of precise emission test data. The requirement for
system qualification was - 2 percent overall accuracy. This requirement
encompassed the constant volume sampler, exhaust analysis console, the
primary CVS flow calibration device, and a laboratory balance. In addition,
the chassis dynamometer was calibrated by the coast-down technique stipu-
lated in the Federal Register.
In addition to the initial qualifications in each of the
cities, EPA personnel supervised periodic calibration and cross check
procedures in each city during the course of the program. No tests were
performed in either city before meeting the qualification or cross check
requirements. Throughout the course of the program, AESi maintained a
schedule for daily, weekly and monthly calibration and maintenance. This
procedure included one hour each morning, plus four hours each week, plus
eight hours each month to perform this function.
2.6.1 Constant Volume Sampler
AESi's CVS's were calibrated with the laminar flow elements
and accessories by the basic procedure specified in the Federal Register.
In addition to measuring CVS flow at ten pressure differen-
tials (Figure 2.6-1), AESi measured flow at several points at inlet
temperatures above and below the set point temperature. During flow
testing all possible variables were measured and accounted for. This in-
cluded an important parameter--the temperature of manometer fluid in
the barometer and the inclined manometer. Blower speed was verified by
means of a 60 Hz strobe light. The inlet and outlet pressures and
temperatures were varied over ranges which surround and include in every
dimension, the set of conditions at which the CVS is operated during
emission testing.

Before inviting EPA personnel to the test site for qualifi-
cation, AESi performed propane recovery tests in the 0-300 ppm carbon
range to ensure proper calibration. For inspecting EPA officers, AESi
repeated propane recovery tests to EPA's satisfaction.
Since CVS calibration is critical, continuous checks had
to be made. Propane recovery tests were performed in the 0-300 ppm carbon
range before testing every day. If the test was not within - 2 percent,
the cause of error was determined, remedied, and duplicate propane tests
within * 2 percent were run before testing began.
The propane test results were plotted so that any upward or
downward trend could be detected. When such a trend developed, the
CVS was immediately recalibrated using a laminar flow element. The
CVS was also leak checked every day. Periodically the pyrometer,
pressure gauges and other CVS instruments were checked for calibration
regardless of need indicated by propane tests. A log book was maintained
for the CVS in which all repairs, alterations, calibrations and propane
tests were recorded. During the course of the program, the St. Louis
CVS system required recalibration on one occasion.
2.6.2 Exhaust Analysis Console (EAC)
Calibration and qualification of the Exhaust Analysis Console
(EAC) was performed as stipulated in the Federal Register. Some of the
procedures discussed here were performed prior to the arrival of the
Project Officer. Prerequisite to qualification of the EAC was analysis
of on-site laboratory gases by the Office of Mobile Source Air Pollution
Control.
Items which were checked and verified prior to individual
instrument calibration were the following: (1) total EAC leak check,
(2) checked zero air quality with hydrocarbon-free air, (3) adjusted
all analyzers to optimize performance as specified by individual instru-
ment manuals, and (4) checked response times for all instruments. The
-------
2-57
following paragraphs describe individual analyzer optimization procedures
and qualification items.
Hydrocarbon Analyzer (Beckman Model 400)
1. Obtain maximum sensitivity using the following
method'
a Set fuel pressure to approximately 25 psig-
b. Set air pressure to approximately 15 psig.
c. Light burner (allow 30 minutes for warmup).
d. Set sample pressure to approximately 4 psig.
e. Flow zero grade air and set zero or. meter or
recorder.
f. Flow raid-range calibration gas.
g. With calibration gas flowing through instru-
ment, adjust air pressure to obtain maximum
upscale reading.
h. Adjust sample pressure to obtain maximum
reading and best response.
2. Develop instrument curves for ranges 0-300, 0-1000,
0-3000, and 0-10,000 ppm.
3. Verify results graphically.

0-8.0 percent.
4. Verify curve results graphically.
Oxides of N'itrogen Analyzer (TECo Model 10A)
1. Verify reaction chamber pressure to be in the
5-12 torr range.
2. Check response time through thermal converter
versus bypass of thermal converter.
-------
2-58
3. Develop instrument curves for ranges 0-100, 0-250,
0-1000, and 0-2000 ppm. (Preliminary converter
efficiency check can be performed during curve
development.)
4. Converter efficiency checks were performed as
described in 38 Federal Register 124, June 28,
1973, Section 85.074-23.
EAC daily and weekly checks which were performed and
recorded are described below:
Daily Check
1. Leak check of HC, CO, CO2 and MO instruments.
2. NO vacuum check.
3. HC analyzer - zero and span.
4. CO analyzer - zero, gain and tune.
5. CO2 analyzer - zero, gain and tune.
6. NO analyzer gain.
Weekly Check
1. Individual instrument curve check of each range used.
2. Converter efficiency.
3. CO response to 100% wet CO2.
2.6.3 Chassis Dynamometer
The Clayton CE-50 dynamometers were calibrated by the coast-
down technique specified in 37 Federal Register 221. A precision tachom-
eter generator was fitted to the absorption rolls for this purpose.
AESi performed the coast-down at several power settings and over the
entire range of inertia values. The driver's aid was adjusted to match
the correct speed according to a 30- and a 60-Hz strobe light. Dyna-
mometer calibration data was plotted graphically on a Dynamometer Road
Load (DRL) form (Figure 2.6-2).
Periodic coast-down calibration checks were performed on
each dynamometer. If the data points did not lie within tolerance (1%
of full scale or 1/2 hp) of the standing calibration curve, the entire
calibration curve set was rerun. A log book and curve file were main-
tained on all dynamometers.

2.7 DATA HANDLING
2.7.1 Data Collection
Several data forms used in past programs were modified for the
In-Use Compliance Program. The Test Data Sheet (Figure 2.7-1), arranged in
keypunch format, contained necessary vehicle information, plus the raw data
generated during the emissions test. Figure 2.7-2 is the Daily Instrument
and CVS System Check form for recording system calibration check data. Used in
conjunction with the Daily Check form is the Propane Recovery Test form (Figure
2.7-3) and the Converter Efficiency Test form (Figure 2.7-4) for recording CVS
calibration and N0X converter efficiency data. In addition to the daily systems
checks, weekly and monthly checks (Figure 2.7-5) were performed to ensure each
instrument curve remained within the limits originally developed.
For each test performed a separate file was maintained for all
paper work dealing with that specific test. This file traveled with the
vehicle through the several functional areas. When the vehicle was returned
to its owner, the file was submitted to the Data Handling Department for
further processing.
2.7.2 Data Revieu
Before a vehicle file was submitted to Data Handling, each task
supervisor (Procurement, I&M, and Testing, in addition to the Laboratory Manager)
was expected to review data generated in his area (see Figure 2.4-1). As vehicle
file folders were received in Data Handling, they were coded, calculations per-
formed, and all forms were reviewed manually. In addition, data contained on
computer cards was subjected to a computerized edit before being forwarded to EPA.
2.7.3 Computer Operations
To develop instrument curves, EPA's curve program, BZERO, modified
for AESi's formats, was used. This FORTRAN program generates all instrument
curves using a second order polynomial method of least squares equation. All
curve generation was performed via terminal entry of data to an IBM System 360
Model 67 located m Sunnyvale, California, functioning under National CSS's
own operating system which is fully compatible with IBM's OS/360.

To perform mass calculations, NCSS's Sunnyvale facility was
used as well as Synalysis, Inc.'s IBM System /3 located adjacent to AESi's
Westminster laboratory. The computerized edit program used to screen for
logical errors on computer cards was operated solely on NCSS. Converting test
data from AESi's format to EPA's format could be done by either NCSS or
Synalysis to minimize down-time.
