ABSTRACT
Emission and fuel economy tests were performed on a sample of
forty-two individually-owned 1977 model-year light-duty vehicles in
the Denver metropolitan area. Vehicles manufactured by Chrysler
Corporation, Ford Motor Company, and General Motors Corporation were
represented somewhat equally. The purpose of these tests was to
investigate emission and fuel economy performance of typical in-use
passenger cars and to quantify the individual and combined effects of
any observable defects, disablement and/or maladjustments on exhaust
emissions and fuel economy.
The investigation followed a test plan in which pairs of vehicles
were separated into two groups. All vehicles were tested in the as-
received condition, after which the first group of vehicles followed a
test plan consisting of a Restorative Maintenance Evaluation. The
second group of vehicles underwent an inspection of engine adjustments
and emission control components and was then returned to the owner. Up
to two additional tests were conducted on the first group of vehicles,
each of which was preceded by a restorative maintenance action.
Each test point consisted of the 1975 Federal Test Procedure (excluding
fuel evaporative loss segments), the Highway Fuel Economy Test and five
short cycle tests. A modest driveability evaluation was also included.

1. INTRODUCTION
The United States Environmental Protection Agency (EPA) is charged
by the Clean Air Act with responsibility for the control and prevention
of air pollution. In carrying out this responsibility, EPA develops,
implements and administers a national program to characterize, quantify
and reduce air pollution from mobile sources. The Emission Control
Technology Division of the EPA is responsible for the conduct of
surveys to obtain emission data from in-use vehicles and studies to
develop and evaluate emission control alternatives. The survey data are
used by the EPA in calculating emission factors and in projecting nationwide
and metropolitan area mobile source emissions. These data are also used in
developing transportation control procedures and contingency programs to
cover emergency situations. Outside the EPA, the emission factors and
emission control alternative data are used by state and local agencies
in their transportation and air pollution control programs. In carrying
out these responsibilities, the EPA's Emission Control Technology Division
conducts in-use vehicle emission factors survey programs and emission
control alternative studies on a regular basis.
With the introduction of 1977 model year vehicles, Federal Regula-
tions required that light duty vehicles meet exhaust emission standards at
the point of sale. Accordingly, the EPA conducted confirmatory emission
certification tests in the Denver area at a contractor's facility, thus
insuring compliance with the new regulations. Subsequent to the certification
and actual sale of 1977 models at altitude, interest developed as to the
effectiveness of emission control on these vehicles. As a result, the
1-1
-------
EPA initiated a Restorative Maintenance Evaluation program, the subject
of this report.
The Restorative Maintenance Evaluation Project was conducted under
the direction of the Emission Control Technology Division of the EPA.
The Project involved evaluations of the 1977 model-year vehicles from
the Denver metropolitan area, Automotive Testing Laboratories, Inc.,
which operates a permanent facility in the area and was conducting the
confirmatory emission certification test, was selected to perform the
work. This report describes the design and conduct of the project and
presents the test results.

2. TECHNICAL DISCUSSION
2.1 PROGRAM OBJECTIVES
The EPA's Emission Factor (EF) programs are designed to develop in-use
vehicle emission data from which nationwide and metropolitan area emission
factors are calculated. Vehicles surveyed under these programs are tested
in the as-received condition. This approach, while permitting an assessment
of in-use vehicles for emission factor determinations, does not provide
specific information on the causes of poor emission performance. The
Restorative Maintenance Evaluation Project was initiated to augment the
in-use data in this regard. More specifically, its objective was to invest-
igate and quantify the individual and combined effects of any observable
defects, disablement and/or maladjustments on exhaust emissions and fuel
economy.
2.2 PROGRAM DESIGN
The program was designed to utilize a sample of forty-two 1977 model-
year vehicles operating in the Denver area. Chrysler, Ford and General
Motors, the major domestic automobile manufacturers, were represented
equally. Sales-weighting techniques were used to specify the vehicle
engines and models evaluated.
The sample was comprised of vehicles procured from the general
public. Each vehicle was no more than five months old with an accumu-
lation of fewer than 4,000 miles. A random sampling technique was
employed to gain access to vehicles conforming to these and specific model,
engine and other identification criteria. Subsequent to the utilization of
this technique, further screening of the candidate vehicles was employed.
2-1
-------
The screening entailed a structured interview of each vehicle owner to
identify a vehicle which had been subjected to unusual operating conditions
or extensively modified from its original configuration. At this point
the vehicle manufacturer became involved in the screening process. This
initial involvement involved a search of warranty records on the vehicle
in question. A vehicle judged atypical in any manner was precluded from
the sample. A suitable vehicle meeting the criteria and passing the screen-
ing, however, was ultimately provided.
Once accepted into the program, the vehicle was evaluated in accordance
with one of two test plans. The forty-two vehicles of the program were
procured as twenty-one pairs; one of each pair designated to undergo test
plan A, the other to undergo test plan B.
Test plan A was designed to bring a non-conforming vehicle, inasmuch
as practicable, into compliance with the Federal Exhaust Emission Standards.
Segments of the Restorative Maintenance plan include an initial test and
one or more additional test sequences. Each test sequence is separated
from the following by a decision point and an appropriate action. Each
of the twenty-one group A vehicles was subjected to the initial test.
The need for further testing was dictated by evidence of individual
vehicle maladjustment, disablement, or non-conformance to the emission
standards.
The twenty-one vehicles of plan B were subjected only to the initial
test. Evidence of maladjustment and disablement was documented but
not corrected.
Individual test sequences in each of the two plans consisted of
a 1975 Federal Test Procedure (FTP), a Highway Fuel Economy Test (HFET)
2-2
-------
and five short cycle tests. This FTP was modified to exclude evaporative
emission measurement and the extensive preconditioning procedures of the
full FTP. The short cycles arc tests which are currently being employed
or under consideration for Inspection/Maintenance (I/M) programs by certain
State and Local agencies. A modest vehicle driveability evaluation was
also included as part of each test sequence.
Other program design criteria included procedures to establish and
verify accuracy of the emission measurements, and for the documentation and
reporting of test data and vehicle identification, diagnostic and repair
information.
2.3 TEST VElilCLE PROCUREMENT
2.3.1 Test Vehicle Procurement Plan
Restorative Maintenance Evaluation (RME) task vehicles were procured
from the general public. 1977 model-year Chrysler, Ford, and General Motors
passenger cars meeting the EPA-provided vehicle procurement criteria were
sought. These criteria included provisions that the vehicles had been in-
use no more than five months prior to the scheduled evaluation and that
fewer than 4,000 miles had been accumulated since the initial sale. Other
procurement criteria were provided on a listing which identified the desired
vehicles by make, model (subcompact, compact, intermediate, etc.) engine
size, transmission type (automatic, manual) and carburetor type (1, 2, 4
bbl and fuel injection). Vehicles comprising the listing were selected by
the EPA on the basis of Colorado registration data using sales-weighted
techniques. It was also specified that any necessary substitutions were
identical in both A and B group vehicles.
2-3
-------
The procurement plan consisted of one primary and one secondary procure-
ment approach. The primary approach was to solicit vehicles from a listing
of randomly selected candidates. In excess of eighty-five percent of the
vehicles tested were procured from this listing. The balance were procured
by the secondary approach which entailed a direct appeal for the required
vehicles via the news-media.
The candidate vehicle listing used in the primary procurement approach
was obtained through the assistance of the Department of Health, State of
Colorado. The Department was able to provide a listing of car owners resid-
ing in the local area around the test facility. The listing was derived from
postal zip-code areas by the random process of nth name selection whereby
each 1, 2, 3, 4 or nth name appearing in the vehicle file is selected. The
value of n is determined by the total number of vehicles appearing in the
areas of interest versus the number of candidate vehicles requested. These
candidate vehicles were subsequently solicited by means of a mass mailing.
Mailing materials consisted of an introductory letter from ATL and a
post-paid information reply card which received EPA approval before they
were employed. The information reply cards contained certain vehicle
identifying information and solicited additional vehicle and other informa-
tion not within the capacity of the mailing firm to provide. The returned
reply-cards were subsequently used in selecting the required vehicles.
2.3.2 Incentives
Certain incentives were offered and provided to enhance response to
the mailing. These were:
A $100 U.S. Savings Bond
Return of the test vehicle with a full tank of fuel
2-4
-------
The use of a late model, fully insured loan vehicle for the time
the owner's vehicle was undergoing tests
Fuel for the loan vehicle
2.3.3 Test Vehicle Selection
We based the preliminary vehicle selection on vehicle identification
information provided on the reply cards versus the EPA-provided listing and
contacted those owners whose vehicles were reported to best meet the
selection criteria. Acceptable substitute vehicles were utilized when
necessary. The first personal contact with the owner was by telephone at
the number provided on the reply card. During this contact, the supplied
information was verified, any void in the information was filled and an
interview to screen atypical vehicles was administered. If the vehicle
appeared suitable the vehicle was scheduled into the laboratory for tests.
A more extensive inspection and screening was subsequently completed at
the laboratory to confirm suitability of the vehicle for tests. The
actual vehicle selection is presented in Table 1 later in this report.
2.3.4 Test Plan
As described earlier, the overall evaluation was conducted on two
vehicle divisions designated as Group A and Group B. A segment of Group
A received an initial test sequence and one or .more additional test
sequences. A segment of Group B followed the Group A plan through the
initial test sequence and an inspection of the engine and emission control
components and subsequently returned to its owner. The paths the vehicles
followed relative to both portions are shown in the flow diagram of Figure
1 which may be referenced in the discussions which follow.

-------
date at the laboratory, the vehicle was given an examination to determine
its suitability for use in the program. Included in this examination was a
verification that the vehicle had not exceeded the age and mileage limita-
tions, that it had not been subjected to unusual operation, that it had not
been extensively modified, and that it was in a safe condition for testing.
Also during this screening process, a sample of tank fuel was drawn and
tested for lead (Pb) content. The lead limit on vehicles requiring unleaded
fuel was 0.05 grams Pb per gallon. This limit is identical to that allowed
in the Federal Register for unleaded fuel.
The outcome of this screening accepted or rejected the vehicle for
further testing. A modest amount of modification, i.e. maladjustment and
disablement, was expected. However, a vehicle having undergone a modifica-
tion of any kind which was not readily, inexpensively, or ultimately restor-
able was rejected at this point. Normally, ATL determined the acceptability
of a vehicle although more complex decisions were made jointly by the manu-
facturer, the EPA, and ATL. The manufacturer was brought into the process
if, on the basis of an interview with the owner, the vehicle was believed
to have had an unusually great number of warranty claims against it. While
a failing mark in a number of areas did not necessarily disqualify a candi-
date, excessive age or mileage, extensive modifications, improper use, or
indications that a vehicle designed to operate on unleaded fuel had used
leaded fuel resulted in immediate rejection. Concurrent with the latter part
of this examination, the owner was given an interview, the results of which
were documented on a questionnaire form. If accepted on the basis of this
screening inspection and interview, vehicle exchange agreements were completed,
the owner was further informed of the purpose of the study, his permission
2-7
-------
was obtained relative to possible maintenance of the vehicle and the vehicle
was retained for use in the evaluation.
Approximately 43 vehicles were delivered to the laboratory for this
initial screening. Of these, 1 was rejected and the required quantity of
forty-two were accepted.
Once accepted at the laboratory, the fuel in each vehicle was drained.
Two samples of the drained, as-received fuel were taken. One of the samples
was made available to the manufacturer; the other was retained for analysis
by the EPA. The first actual test sequence began after the as-received
fuel was drained and replaced with test fuel to the prescribed charge of
40 percent of tank volume. The charge relative to any subsequent test
sequences was merely to restore tank fuel to the 40 percent level.
Each of the test sequences described below consisted of: operation of
the vehicle for 10 minutes on city streets; a 12 to 24 hour soak period
during which the vehicle remained unstarted at ambient temperatures from 68°F
to 86°F; the Federal Test Procedure (FTP) excluding the evaporative emission
test segments but including the cold transient, cold stabilized and hot
transient phases of the FTP; the Highway Fuel Economy Test; five short
cycle tests including the Federal Short Cycle Test, a composite of the
New Jersey ACID and New York Short Tests, the Clayton Key Mode Test, the
Two Speed Idle Test and the Federal Three Mode Test; and, following the
dynamometer sequence, the measurement of basic engine parameters. FTP
emission results were calculated shortly after completion of the sequence
to facilitate decision-making and to expedite routing of the vehicle
through the program. Details concerning preconditioning, performance of
the above tests and considerations given each vehicle manufacturer relative
2-8
-------
to evaporative emission control system configurations during the tests
are provided under TEST PROCEDURES, 2.5, of this report.
With reference again to the Figure 1 flow diagram, Test //I was
conducted with the vehicle in the as-received condition. Any maladjust-
ment or disablement found during the initial examination of the vehicle
had not been corrected at this point.
Following Test //I, the inspection for Maladjustment or Disablement
was performed. For the purpose of this examination, the pass-fail decision
was based solely on whether the emission control parameters or components
had been subjected to either or both of these actions or not. Areas that
were in question due to deterioration or production defects were disregarded
at this point but were subsequently treated as failures during functional
checks of the emission control parameters and components. After completion
of the Maladjustment and Disablement Inspection, the Group B sequence was
complete. With respect to a Group A vehicle, if any maladjustments of dis-
ablements were discovered, these were corrected and Test #2 was conducted.
Following the finding that no maladjustments or disablements had
been performed or the correction of these and the subsequent performance
of Test #2; the Emission Components Inspection was performed. As a practical
matter, the Maladjustment/Disablement Inspection and the Emission Component
Inspection were performed concurrently, when applicable. Failures relative
to the Emission Component Inspection were not corrected in conjunction
with this inspection but were corrected in conjunction with the Emission
Component Repair actions prior to Test //3.
At this point, FTP results from the most recent test (normally #1 but
sometimes #2) were examined. If the vehicle passed the Federal Emission
2-9
-------
Standards, it was returned to its owner. Vehicles which failed the Federal
Emission Standards on this test were subjected to the Emission Component
Repair action.
The Emission Component Repair consisted of the correction of malfunction-
ing emission control devices and other emission related components. Test //3
followed these repair actions. A consultation was held with the EPA and
the vehicle manufacturer concerning the vehicle which failed Federal Emission
Standards relative to this test. This consultation was followed either by
maintenance and a retest or the return of the vehicle to its owner.
2.4 TEST FACILITY AND EQUIPMENT
The test facility and equipment are located at 19900 E. Colfax Avenue,
Aurora, Colorado. This is a permanent facility, situated six miles to
the east of Denver at an altitude of 5480 feet above sea level.
The FY 75 Emission Factors Program immediately preceded the Restorative
Maintenance Evaluation and the related facility and equipment initial
check-out was conducted in conjunction with the FY 75 Emission Factors final
check-out.
Other daily, weekly, bi-weekly, and monthly calibration and cross-
check frequencies and procedures were performed under the related Emission
Factors program and specifications.
2.5 VEHICLE TEST, INSPECTION AND MAINTENANCE PROCEDURES
Each vehicle was subjected at each test point to a prescribed sequence
of preparation, preconditioning, testing and de-prepping procedures. This
sequence was performed as follows:
Vehicle Preparation
Federal Test Procedure
Highway Fuel Economy Test
2-10
-------
Federal Short Cycle
New Jersey ACID/New York Short Test Composite
Clayton Key Mode Test
Two Speed Idle Test
Federal Three Mode Test
After-Test Procedures
The various inspection, adjustment, tune-up and maladjustment procedures
were performed in accordance with the test plan. Details on these, test-
ing and other procedures are provided in paragraphs which follow.
2.5.1 Vehicle Preparation
As described earlier, the test sequence began with the fueling of the
vehicle. Prior to the first test the as-received fuel was drained from
the vehicle. In this process fuel was drained either from the tank filler
neck or from the supply line to the engine. An electrically powered gear-
type pump was used for this purpose. Separate one-pint samples from each
tank were retained for the vehicle manufacturer and the EPA. Following
the draining process, the tank was charged to 40 percent of tank capacity
with a suitable Indolene fuel. The Indolene fuels were obtained from
American Oil Company from its stocks in the Detroit area and delivered
in 55 gallon drums. Prior to the second and subsequent test sequences
the vehicle tank was merely topped-off to the 40 pecent level with the
appropriate fuel. Caution was exercised relative to the fuel in that
opened drums were resealed after each use and unleaded fuel dispensing
equipment was used only in connection with the unleaded fuel.
Some time after the refueling process was completed, the vehicle was
operated on city streets to purge as-received fuel from the carburetor and
2-11
-------
fuel lines and to evaluate warm engine driveability characteristics. Such
operation continued: a minimum of 10 minutes; until engine temperature had
stabilized or; until the driveability evaluation was completed; whichever
occured last. Following this process the vehicle was immediately driven
to the soak area and shut-down to begin a prescribed 12 to 24 hour soak
before the Cold Start FTP.
2.5.1.1 Vehicle Driveability Evaluation - Driveability evaluations were per-
formed from a warm and a cold engine start. The warm driveability evaluation
was conducted in connection with the city street, fuel purging operation
while the cold engine evaluation was conducted in conjunction with the cold
transient phase of FTP dynamometer operation. The evaluations are regarded
as being modest in that they were performed under limited conditions and
were designed to generalize on undesirable elements as opposed to charac-
terizing each of the possible undesirable elements.
The warm engine driveability evaluation consisted of:
A constant speed phase
An acceleration-from-idle phase
A restart after shut-down phase
During the constant speed phase, "stalls" and "pass-outs" were noted during
part throttle acceleration to road speed (generally to posted speed limits
below 55 mph), acceleration quality was noted, cruise quality was noted,
response during slight acceleration was noted, and idle quality at stop was
noted. During the acceleration-from-idle phase, acceleration quality at
1/4, 1/2, 2/3 and 3/4.throttle was noted. During the restart after-shut-
down phase, cranking time and idle quality after restart were noted. The
restart was performed 10 minutes after the engine was shut-down upon com-
2-12
-------
pletion of the preceding phases.
The cold engine (dynamometer) driveability evaluation consisted of:
A cold start and idle phase
A drive-away phase
During the cold start and idle phase, initial cranking time and idle quality
were noted, "die-outs" and "stalls" were noted, and hesitations during the
first acceleration were noted. During the drive-away phase, "stalls" and
"pass-outs" during subsequent FTP first cycle accelerations were noted,
acceleration quality during this cycle was noted, idle quality after the
first cycle was noted, stalls and pass-routs during FTP second cycle acceler-
ations were' noted, acceleration quality during the second cycle was noted
and idle quality after the second cycle was noted.
In order to reduce the degree of subjectivity in this evaluation,
several categories of ratings were used. These are described as:
Excellent - indicating no trace of undesirable elements (smooth,
even, responsive).
Good - indicating slight trace, small indication of an undesirable
element (initial uneveness, roughness, hesitation, quickly
overcome).
Fair - indicating an undesirable element exists yet reliability
is maintained (only intermittent misfire, surging, hesitation).
Poor - indicating an undesireable 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).
Pass-outs are defined as an "off-idle" stall while die-outs are defined as
a stall at idle.
2-13
-------
2.5.2 Equipment Preparation
The facility was operated on a three shift per day, five day per week
basis. Such continuous operation precluded many of the usual daily labora-
tory start-up operations. When applicable, however, instruments which had
been idle or in a stand-by condition were switched on to begin the warm-up.
This included the water heater and mass pump of the CVS and the analytical
instruments. During and following the warm-up period, but at least once
each day, sensitivity of the automatic sample line leak detection system
was checked, NOX instrument converter efficiency and CVS propane recovery
tests were performed, analyzer outputs as indicated by the recorders and the
computer were checked for standardization and the dynamometer was warmed-up
for a minimum of fifteen minutes at 30 mph if it had not been utilized for
testing within the previous two hour period. Speed calibrations of the
dynamometer and associated indicating devices were also standardized and the
tailpipe sampling system was checked for leaks. During this interval, the
soak area temperature trace and other general laboratory quality control
documentation from the previous day were collected for evaluation and pro-
cessing.
2.5.3 Federal Test Procedure
The Federal Test Procedure was conducted in accordance with the pro-
cedures listed in 40 Federal Register^ 126. Those segments of the procedure
which deal with fuel evaporative loss measurements were not conducted,
however. Consequently, special concessions relating to the configuration
of the evaporative emission control system were requested of the EPA and
granted to the manufacturer of the vehicle under test.
This version of the FTP is conducted from a cold engine start. Prior
2-14
-------
to the test the vehicle remained unstarted for a period of twelve to twenty-
four hours at ambient temperatures between 68°F and 86°F. Following this
soak interval the inertia weight and load settings of the dynamometer were
set to correspond to the weight and load settings for the vehicle next in
line to be tested. A non-test vehicle was used for this purpose. The
manufacturer prescribed the settings which were those used for testing
of the pre-production versions of the respective vehicles as part of the
EPA emission certification process for each vehicle model-year.
Following the load-set, the test vehicle was placed on the dynamometer.
The test equipment was prepared and placed in the test start-up configura-
tion. Simultaneously, the vehicle engine was started and exhaust sampling
was initiated. This sampling continued during the 505 second, 3.59 mile
cold transient phase of the test. At the 505 second point the sample was
diverted from the first sampling bag of the CVS to the second. The second
bag was used to collect the exhaust sample from vehicle operation over the
3.91 mile cold stabilized phase of the test. At the end of this phase
the engine was stopped, cold stabilized phase sampling was terminated and
the vehicle was soaked on the dynamometer for a period of ten minutes +
one minute. At the end of this period the engine was restarted at which
time exhaust sampling was once again initiated and continued through the
505 second, 3.59 mile hot transient phase of the test. This concluded the
Federal Test Procedure.
CVS sample and background bags were analyzed within 10 minutes after
completion of the respective phases of the test. Temperature of the air
in front of the vehicle during the test was maintained between 68°F and
86°F.
2-15
-------
2.5.4 Highway Fuel Economy Test
The Highway Fuel Economy Test consists of vehicle operation on the
dynamometer over the 10.242 mile, 765 second HFET driving schedule. This test
followed the FTP and was started with the vehicle in a warmed-up condition.
A warmed-up condition was defined as at least 7.5 miles of cyclic operation
having been completed within the thirty-five minute period preceding the
start of the HFET. The vehicle was preconditioned for this test by operating
it at 50 miles per hour for a period of three minutes. Within one minute
of the end of this cruise period the vehicle was brought to an idle condition
and the test was started. At the start of the sampling period, CVS diluted
exhaust is diverted into the sample bag and collected during vehicle operation
over the HFET driving schedule. Sampling is terminated at the end of the
schedule and the content of the sample bag is analyzed for emission and fuel
economy determination. Load settings, inertia weights and the vehicle speed
and underhood cooling air temperature tolerances of the HFET are identical
to those of the Federal Test Procedure.
2.5.5 New Jersey ACID/New York Short Test Composite
The New Jersey ACID/Hew York Short Test Composite is a six mode mass
(CVS) emission test of 75 seconds duration which follows the driving
schedule listed as follows:
Mode Time in mode (sees)
Idle 22
0-30 mph acceleration 15
30 mph cruise 15
30-10 mph deceleration 12
10 mph cruise 7
10-0 mph deceleration _ 4

-------
On all vehicles the dynamometer is loaded to an inertia weight of 3,000
Ibs and 3,5 indicated horsepower at 30 miles per hour. Manual transmission
shift points are the same as those observed during the Federal Test
Procedure. Flow into the sample bag was such that a minimum of two cubic
feet of dilute exhaust sample was provided for test analysis.
2.5.6 Clayton Key Mode Test
The Clayton Key Mode Test consists of three steady state operating
conditions. An undiluted (tailpipe) exhaust sample is analyzed during
each of the three conditions.

For the purpose of this program, the Clayton Key Mode Test was pre-
ceded by a soak period no longer than 20 minutes from the last sustained
period of vehicle operation. At the end of this period the vehicle was
operated a maximum of three minutes at the specified speed and load with
the engine compartment open and the underhood cooling fan on. The Federal
Test Procedure inertia weight was engaged during the test. The mode sequence
was in the order of high cruise, low cruise and idle. At each speed
equilibrium of vehicle speed and the HC, CO and NOX readings were maintained
2-17
-------
for 30 seconds before the readings were recorded. Operating conditions
for the test are as listed.
2.5.7 Two Speed Idle Test
The Two Speed Idle Test consists of two steady state operating conditions.
An undiluted (tailpipe) exhaust sample is analyzed during each of the two
conditions. The first is a mode in which the engine is operated at 2250
engine rpm with the transmission in neutral. During the second, the engine
is operated at normal idle with the transmission in neutral also.
In this program, the Two Speed Idle Test was also preceded by a soak
period no longer than 20 minutes from the last sustained period of vehicle
operation. At the end of the soak period the vehicle was operated for a
maximum of three minutes at 2250 engine rpm and then at curb idle. At
each speed, equilibrium of vehicle speed and the CO, HC and NOX readings
were maintained for 30 seconds before the readings were recorded.

in that it also consists of three steady state operating modes and measure-
ment of tailpipe emissions. Since actual (as opposed to indicated) dyna-
mometer horsepower settings are used, additional dynamometer calibrations
at 30 mph and 50 mph were performed. Federal Test Procedure inertia
weights were engaged during the test. The mode sequence was in the order
of high cruise, low cruise, and idle. At each speed, equilibrium of
vehicle speed and the CO, HC and NOx readings were maintained for 30
seconds before the readings were recorded. Operating conditions for this
test are as listed.
2.5.9 Vehicle After-Test Inspection, Adjustment and Maintenance Procedures
The After-Test Procedure involved the measurement of basic engine
parameters. These parameters consisted of; basic ignition timing, dwell
(if applicable), idle speed, undiluted idle CO and undiluted idle HC. In
performing these measurements, the procedures outlined on the emission
data sticker found in the engine compartment were followed.
Other of the inspection, adjustment and maintenance procedures are
described, in general, in paragraphs which follow:
2.5.9.1 Maladjustment and Disablement Inspection - The Maladjustment and
Disablement Inspection (Appendix I) was designed to determine whether the
emission control parameters or components had been subjected to either or
both of these actions. In making this determination, the manufacturer's
service manual was referenced. The scope of this inspection was as follows:
The induction system was inspected to determine if it was intact and
complete. Included was a determination that the heated air system
was operative and that the vacuum lines controlling operation of the
system had not been disconnected, plugged or rerouted.
2-19
-------
The carburetor and fuel system was inspected to determine if it was
intact and complete. This inspection was to determine that the choke
system had not been modified or misadjusted, that the idle mixture
limiter caps were not missing or broken and that the fuel tank filler
neck had not been altered.
The ignition system was inspected to determine if it was intact and
complete. Included was a determination of; the distributor number,
initial timing, mechanical advance at an appropriate intermediate
speed and the points at which vacuum advance began and when maximum
vacuum advance was attained.
The exhaust gas recirculation (EGR) system was inspected to determine
if it was intact and complete. Included was a verification that the
vacuum signal lines had not been disconnected, plugged or rerouted
and that the entire system was operable.
The air pump (secondary air) system was inspected to determine if it
was intact and complete.
The positive crankcase ventilation (P.C.V.) system was inspected to
determine if it was intact and complete.
The exhaust handling system was inspected to determine if it was in-
tact and complete.
The evaporative emission control system was inspected to determine if
it was intact and complete.
Any other components related to exhaust emission control were inspected
to determine if they were intact and complete.
2.5.9.2 Emission Component Inspection - This inspection was designed to
determine the operational status of each component within the emission
control system. For the purpose of this inspection, components that were
not operating properly but yet had not been maladjusted or disabled were
judged to be defective. Specific procedures relative to each vehicle and
manufacturer were obtained from the respective service manuals. The pro-
cedures are too detailed to list. Insight into the Emission Component
Inspection may be gained through an inspection of the reporting forms
applicable to the process. These are also provided in Appendix I.
2.5.9.3 Idle Speed and Mixture Inspection - The Idle Speed and Mixture
2-20
-------
Inspection was designed to determine if these parameters were out of the
prescribed tolerances and, if so, to what extent. Specific procedures
relative to each vehicle and manufacturer were obtained and/or developed
from the respective service manual. These procedures are presented in
Appendix I.
2.5.9.4 Emission Component Repair - Components found to require attention
under the Emission Component Inspection were corrected when the vehicle
reached this point. Insight into the details of the Emission Component
Repair may be gained through a inspection of the reporting forms applicable
to the process. These, also, are provided in Appendix I.
2.6 DATA HANDLING
The raw data and associated materials were subjected to a systematic
and rigorous sequence of collection, preliminary review, packaging, and
an editing prior to final processing. This sequence is described below.
2.6.1 Data Collection
Critical parameters associated with the test were documented on strip-
chart recorders. Included in these parameters were the temperature of the
soak area, wet and dry bulb temperature of the air supplied to the vehicle
during the test, temperature of the dilute exhaust within the CVS and
driver/vehicle performance over the various driving schedules. Driver/
vehicle performance recordings contain a speed calibration before the test
and a calibration check after the test. Recorders associated with the
emission analytical system were allowed to run continuously during the
prescribed analyzer calibration, sample measurement and calibration check
sequence.
The NOVA 2 computer, the primary component in the data acquisition
2-21 .
-------
system, was utilized to collect and integrate CVS sample and background
bag HC, CO, C02 and NOx data. This component of the system was also used
to generate the speed/time profiles of the various driving schedules, which
are based on a 10 speed-point/second smoothed signal, and to totalize the
revolutions of the CVS mass pump during each of the mass emission test
segments.
Routing of the vehicle through the preconditioning, test, inspection
and maintenance sequences was controlled through the utilization of a data
form packet which was assigned to each vehicle. This packet contained all
forms necessary to document the procedures to be applied to the given
vehicle. Assembly of the packet was in the order in which the procedures
were to be applied. Supplements were added as the decisions regarding
further action on the vehicle were made.
Control over the vehicle soak period was maintained and documented
through utilization of the reporting block provided on one of the packet
forms. A separate copy of this form was used in connection with each cold
start test. Additional control was exercised to maintain the proper soak
interval through the use of posters which were affixed to the vehicle
windshields. Each poster contained a numeral which indicated the order in
which the vehicle was to appear in the daily testing schedule and a block
on which the key-off time relative to the specific vehicle was noted. Test-
ing personnel were also furnished a schedule which indicated the daily test-
ing schedule including the vehicle order and the nominal test time. Personnel
performing the preconditioning operations were furnished with a similar
schedule indicating the time each vehicle to be tested was to be placed in
soak.
2-22
-------
Upon completion of a vehicle test, the completed data packet, strip
chart recordings, data acquisition system computer punch tape and print-outs
pertinent to the test were assembled in preparation for the review process.
2.6.2 Data Processing
Processing of the raw data was performed by both manual and computer
operations. Aside from the above mentioned acquisition and reduction
(integration) operations performed by the on-line computer and those test
parameters monitored by strip chart recorders, also mentioned above, the
collection of data was a manual operation. Generally, data were processed
using a time share computer system. However, manual verification of strip
chart compliance with temperature and speed tolerances, procedural operations
and integration of the wet/dry bulb temperature traces was required.
Raw Federal Test Procedure data were processed on a preliminary basis
o (
to facilitate the decision making process. The manufacturer's representative
was provided machine copies of the preliminary print-out of the FTP data.
These and the remaining data were subsequently reprocessed using the same
time-share system once the final phases of the data review and edit process
were completed. Due to possible changes stemming from the initial review
and edit process, the final results may not agree precisely with results
supplied to the manufacturers.
2.6.3 Data Review and Editing
All data pertaining to a single vehicle were assembled into a single
test packet. The packet contained all raw data sheets, strip chart record-
ings, data acquisition system punch tape and print-outs pertinent to the
vehicle test. These were reviewed for completeness, compliance with temp-
erature and speed tolerances and procedural accuracies on a test by test
2-23
-------
basis. Any data deficiencies, out-of-tolerance conditions or procedural
inaccuracies were resolved at this point. Resolution was appropriate to
the particular discrepancy and covered whatever actions were necessary
up to and including a complete rerun of the test. Upon completion of
all tests on the vehicle, but before it was returned to its owner, the
entire test packet was reviewed and any remaining discrepancies were like-
wise resolved. The completed packet was subsequently forwarded to the Data
Processing department for further processing.
Upon arrival in Data Processing, the data packet was subjected to a
third review by personnel who are not directly connected with the tests.
This review-was similar to, but more comprehensive than, the preliminary
reviews performed by the test personnel. Any deficiencies or discrepancies
noted at this point were resolved. Following this review, data contained
on the on-line computer punch tape generated at the test cell were combined
with other of the raw data and entered into temporary time-share computer
storage. The stored data were subsequently listed back out and manually
proofread against the input data to detect any errors introduced through
key-punch operations or transmission difficulties. Errors of this type
were corrected at this point. The data were subjected to an edit program
when these procedures were completed.
The editing process to which the data were subjected is a computer oper-
ation which subjects the critical bits of data or information to a test of
reasonableness. Such reasonableness is established if the point in question
lies within a pre-determined range or tolerance. For example, the reasonable
range for temperature (dry bulb) of air supplied to the front of the vehicle
during testing, is 68°F to 86°F, the actual tolerance for this parameter of
2-24
-------
the test. If the respective point is outside this range, the computer flags
the point indicating a requirement for further investigation. In those
cases where an absolute value or values are applicable, any other value
appearing in the given location is similarly flagged and investigated.
Engine displacement size, where a limited number of sizes are available
respective of one vehicle model, is an example of an absolute value to which
compliance with the edit program needed also to be demonstrated. Once each
problem relating to the flagged points had been resolved, the data were
reduced. The computer performed these operations, as well. As a last
check, the reduced data were printed-out and subjected to a final review
and subjective test of reasonableness before the test was declared valid.
When this process was completed, the data were transferred to the EPA in
the form of interpreted 80 column punch cards along with the complete data
packet.
The EPA conducted a similar review of the data including both raw and
processed data. Any discrepencies noted during this process were brought
to our attention and resolved in an appropriate manner. The computer data
files were corrected accordingly and 80 column punch cards covering the
corrected data were resubmitted.
2.6.4 Calculation of Test Results
Mass emission test results were calculated using basic formulae of
40 Federal Register 126. Fuel economy data for these tests were calculated
from mass HC, CO and C02 results using the carbon balance equation. A
hydrogen/carbon ratio of 1.85 was assumed for these fuels. Calculation
methods for the particular tests are described below.
2.6.4.1 Federal Test Procedure - FTP results were calculated using Federal
2-25
-------
Register equations.
2.6.4.2 Highway Fuel Economy Test - Emission results for this test were cal-
culated using Federal Register equations and a distance constant of 10.242
miles per test. Fuel economy results were calculated using the carbon
balance equation.
2.6.4.3 Federal Short Cycle Test - Results for the Federal Short Cycle Test
were calculated using Federal Register equations and the distance constant
of 0.7536 miles per test.
2.6.4.4 New Jersey ACID/New York Short Cycle Test Composite - Emission results
for this test were calculated using Federal Register equations and the
distance constant of 0.2792 miles per test.
2.6.4.5 Clayton Key Mode Test - Emission results for this test are comprised
of tailpipe concentrations which were given no treatment and are reported as
measured.
2.6.4.6 Two Speed Idle Test - Emission results from this test are also com-
prised of tailpipe concentrations which are reported as measured.
2.6.4.7 Federal Three Mode Test - Emission results from this test are tail-
pipe readings which are reported as measured.
2.6.4.8 Vehicle After-Test Inspection, Maintenance and Adjustment Procedures -
Emission readings taken during these procedures are reported as measured.
Data on the basic engine parameters and on emission control and related
parameters are reported as measured or observed in terms appropriate to the
measurement or observation. Cost data relative to replacement parts are
based on either actual retail invoice prices in cases where ATI supplied
the parts or retail price quotations provided by the respective manufacturer
in cases where the manufacturer supplied the parts.

3. PRESENTATION OF TEST RESULTS
Data that are particularly pertinent to the objectives of the Restora-
tive Maintenance Evaluation are summarized in tabular form in this section.
A more detailed presentation is provided in the appendices.
It was not within the scope of the testing laboratory's contract: to
perform other than a minimal analysis of the data; to present or discuss it
in any detail or; to draw any conclusions from the results. Consequently,
relatively little discussion accompanies this section except that which may
serve to clarify the test conditions.

3.3 SUMMARY OF MALADJUSTMENT AND DISABLEMENT
A summary of the occurances of maladjustment and disablement actions
relative to the major engine and emission control systems and the vehicle
manufacturer is presented in Table 4. The only explanation believed necessary
here is that: 1) these actions may have been taken on more than one major
system relative to a given vehicle or; 2) none of these actions were taken
relative to a single vehicle. As a consequence, the total number of vehicles
by manufacturer on which the actions were taken need not be equal to the
total number of occurances appearing in the manufacturer column.

4. SELECTIVE MALADJUSTMENTS AND DISABLEMENTS
Following completion of the Restorative Maintenance Evaluation Test-
ing one vehicle (No. 7114) was selected to undergo testing in a Selective
Maladjustment Program. These selected maladjustments and disablements
represented what could be considered to be a prevalent of modification.
The first test of this sequence was performed with all adjustments
and settings as specified by the manufacturer. This was followed by five
tests, in each of which various parameters or components were singularly
maladjusted or disabled. Parameter options that were evaluated in this
five test loop were as follows:
EGR hose disconnected
Air pump deactivated
Choke 3 notches richer than spec.
5° timing advance from spec.
Rich best idle
Data relating to FTP emission/fuel economy and HFET results are
summarized in Table 8. The following key is provided to facilitate the
interpretation of these data:
BASE TEST represents the test results obtained with all adjust-
ments at manufacturer's specifications.
Under BASE TEST are data relating to the listed maladjustment
or disablment.
% CHANGE indicates the change from BASE TEST results to the
maladjustment or disablement test result.
