the propane recovery test involving the CVS sample system and the FID hydro-
carbon instrument was conducted. Subsequent to these checks, analyzer out-
puts, as indicated by the strip chart recorders and the DACC computer and
printer, were checked for correlation by calibrating at zero and five
volts. Prior to the first exhaust emissions test of the day or following
any extended shut-down, the dynamometer was warmed-up. The prescribed 15
minutes of 30 mile per hour operation of the dynamometer was the warm-up
procedure followed. Following warm-up, the speed calibration of the dyna-
mometer, driver's aid recorder and associated indicating devices were also
checked and calibrated as necessary.

Prior to each test, all charts were properly stamped to show,
among other things, the vehicle number, run number, date and persons involv-
ed in the test.

2.6.3 Initial Screening

This written procedure should be used in conjunction with the
Test Flow Chart presented in Figure 2.

All vehicles were screened upon arrival at AESi for "obvious
pass" classification. The screening consisted of a tailpipe test for the
presence of lead, using plumbtesmo test paper, an underhood component
inspection and a 4-mode idle emissions test. The plumbtesmo lead test pro-
cedure is presented in Figure 4. The plumbtesmo test paper was attached to
the underhood/EGR inspection form and submitted with the other test data to
the EPA Project Officer.

The underhood component inspection was originally planned to du-
plicate the inspection performed at the State Inspection Lanes. The under-
hood/EGR inspection procedure was developed by AESi based on California Air
Resources Board and the Bureau of Automotive Repair supplied requirements.
An underhood/EGR inspection form is presented in Figure 4 with the EGR test
procedure. It was later determined that the AESi underhood check was a far
more intense inspection than the inspection being performed at the State
Lanes. As a result several vehicles were failing the initial screening at
AESI, passing the State Lane inspection and being tested further as
“incorrect pass" vehicles. Consequently, EPA decided that all vehicles
tested after September 19, 1980 would receive the initial screening tests
(plumbtesmo lead test, underhood/EGR check and 4-mode idle emissions test)
but pass/fail would be determined by the emissions test only. This elimi-
nated any possibilities of incorrect pass vehicles.

2.6.4 State Lane Inspection

The State Lane inspection station testing consisted of a very
quick underhood inspection and a State Loaded 2-Mode emissions test. The
State Loaded 2-Mode test included 40 MPH Cruise (at specified loads*) and
idle in neutral. The cost of the test was $11 and a retest, should the veh-
icle fail, was $7.

2.4.3.1 Laboratory Standard Calibration & Working Gases

Laboratory standard calibration gases, previously approved by
EPA, were used for defining instrument calibration curves and assigning con-
centration values for the working gases. Each cylinder of standard gas and
each working gas cylinder was equipped with its own pressure regulator as
specified by the contract. All gases were plumbed to a quick-disconnect
panel for ease in selecting the gas desired during calibration and testing.

Calibration gases for each range of the HC and NOx analyzers were
chosen such that three points were used across the curve (zero and approxi-
mately 45% and 90% of full scale concentration). CO and C05 calibration
points were at zero and approximately 15, 30, 45, 60, 75 and 90 percent of
full scale. All span gases were 80-100 percent of full scale.

The diluents used in the calibration and working gases are:

HC, ppmc Propane in HC free air
NOx, ppm In zero grade nitrogen
CO, mole % In zero grade nitrogen
COs, mole % In zero grade nitrogen

2.4.4 Sealed Housing For Evaporative Determinations (SHED)

Evaporative emissions tests were performed using an AESi SHED and
its associated operator console. The SHED meets all requirements of 40 CFR
Part 86. The console includes a Beckman 400 FID analyzer with ranges of
0-100, 0-300, 0-1000 and 0-3000 ppmC; a Linear Instruments chart recorder
for analyzer output; a Leeds and Northrup SPEEDOMAX multipoint temperature
recorder; and a variable voltage source and heating element (blanket) for
applying heat to the vehicle gas tank for the diurnal heat build. A cooling
package is installed to ensure operation of the SHED within the temperature

ABSTRACT

This report presents and summarizes exhaust emissions test data
and other related information obtained in the testing and inspection of 55
in-use passenger cars. The test fleet consisted of 1975-1979 automobiles.
The test vehicles were obtained randomly from private owners in the Los
Angeles and Orange County areas. The testing was completed October 1980.

Each vehicle was tested in as-received condition and given an
underhood emissions control component inspection. The test sequence con-
sisted of a tailpipe test for the presence of lead, an underhood emissions
control component inspection and a four-mode idle emissions test. Vehicles
passing this initial screening were returned to the owners and those veh-
icles failing the screening remained at AESi for more extensive testing.
The vehicles remaining at AESi received a State Lane inspection, a 1975
Federal Test Procedure, a Highway Fuel Economy test, a 50 MPH Cruise test, a
Four-Speed Idle test, a Federal Loaded Two-Mode test, a State Loaded
Two-Mode test, a Four-Speed Idle test with one spark plug disconnected and
needed repairs performed by AESi and state qualified commercial repair
facilities. Three of the vehicles remaining at AESi received SHED evapora-
tive emissions testing.

range in use. Converter efficiency of the NOx converter was maintained
above 90 percent. The noise level of analyzer outputs as indicated on the
strip chart was maintained within +0.5 percent of full scale for the range
used during both calibration and analysis.

2.5.2.2 Raw Exhaust Analysis Console

The NOx instrument used in the undiluted (raw) emission analysis
console is a laboratory instrument calibrated using the same gases, calibra-
tion points, tolerances and verification frequency described above in con-
nection with the NOx instrument used in the mass emission analysis console.
Efficiency of the tail pipe raw exhaust NOx laboratory instrument thermal
converter was not checked daily because NO (Nitric Oxide) was measured and
reported, not NOx (Oxides of Nitrogen).

The tail pipe HC/CO measurement instrument was operated in ac-
cordance with the manufacturer's recommendations except that this instrument
was zeroed with nitrogen and the HC and CO span-points calibrated with
appropriate gases immediately prior to each test. Each analyzer was checked
for zero and span point drift immediately following each test.
2.5.2.3 Daily Qualification Checks

Daily qualification checks included:

Leak-check of each instrument as well as the system.

Recording of zero, gain and tune, as applicable, for
each instrument.

Hang-up and leak-checks for background and sample
bags and sample line.

NOx analyzer vacuum and converter efficiency checks.

Propane recovery tests to ensure proper FID opera-
tion as well as verification of the CVS calibration.

Recording of FID fuel and air pressure.

Recording of cylinder number, concentration, deflec-
tion, cylinder pressure for each working gas.

In addition to the above daily checks, weekly calibration curve
checks were made for each range of each instrument.

Appropriate calibrations, leak-checks, etc., were also made when-

ever maintenance was performed which could change instrument or system oper-
ation.

and a heat exchanger utilizing cold water (68°F) to maintain the ambient
temperature within the SHED.

2.4.5 Chassis Dynamometer

The chassis dynamometer was equipped to simulate vehicle inertia
and road load horsepower as required in 40 CFR Part 86.

The dynamometer used was a Clayton ECE-50 with 17 1/4 inch roll
spacing and 8 5/8 inch diameter rolls. Direct drive variable inertia load-
ing weights were employed, with 250 pound increments from 1,750 through
3,000 pounds and 500 pound increments from 3,000 through 5,500.

A speed meter which indicates mi/nr was used to monitor the speed
of the dynamometer roll. The rear dynamometer roll is equipped with a ta-
chometer generator which provides the speed signal during testing. The
meter response was linear with speed and the accuracy was within +2.0 km/hr
(+1.2 mph) over the range of 0-95 km/hr (0-59 mph). The dynamometer was
equippped to measure actual distance traveled for each segment of the FIP
testing sequence. However, the theoretical distance for each segment was
used in the exhaust emissions calculations.

The power absorption unit was monitored by a power meter accurate
and readable to +0.25 hp (0.187 kw) over the range of intended use.

2.4.6 Data Acquisition System

Data were obtained from the analyzers, CVS and dynamometer via an
AESi Data Acquisition Control Computer (DACC).° A Data General NOVA computer
was used for generating driver traces for the various driving schedules, for
sample bag management and for calculation and presentation of the emission
test results. The data were printed by a Data General Dasher printer imme-
diately following sample analysis.

The output from the analyzers was also wired to four
Hewlett-Packard Model 7130A two-pen recorders. One recorder was used for
dilute HC and NOx, one for dilute CO and COz, one for undiluted HC and CO
and one for undiluted NO.

2.4.7 Driver's Aid

A two-pen Hewlett-Packard Model 7130A Driver's Aid (speed vs time
recorder) was employed to permanently record the driver's performance during
the test. The driving trace was generated by the NOVA computer on this re-
corder in agreement with the specifications of 40 CFR Part 86.

2.4.8 Miscellaneous Equipment

Miscellaneous equipment used in conjunction with the major items
of equipment included the following:

SECTION 2

TECHNICAL DISCUSSION

2.1 PROGRAM OBJECTIVES

This report describes a program conducted by Automotive Environ-
mental Systems, (AESi) to gather information on the effectiveness of south
coast air basin change of ownership I/M program. The testing was conducted
between August 1980 and October 1980.

2.2 PROGRAM DESIGN

The emphasis of this project was to gather information on the
effectiveness of south coast air basin change of ownership I/M program. The
effectiveness of this program may aid other areas in the implementation of
similar programs. The test fleet consisted of 1975-1979 vehicles specifi-
cally selected by the EPA to represent a cross-section of vehicles that had
possibly undergone a change of ownership since the program began.

2.3 TEST VEHICLE PROCUREMENT

A list of vehicle makes and engine families was provided by the
EPA. Specific guidelines were provided as to the quantities desired from
each of these engine families.

In an effort to avoid biasing the sample, the number of vehicles
procured from members of commercial, civic, fraternal, or religious organi-
zations was limited to fifty percent of the vehicles from any one model
year. The use of rental, leased or fleet vehicles was forbidden. Groups of
vehicles were not obtained from organizations which are automobile oriented.

2.361 Test Vehicle Selection

Test vehicles were selected based on guidelines provided by the
EPA Project Officer.

Test vehicles were solicited using various methods. The primary
method was from vehicle registration lists purchased from a _ market
information service company, from which mailings were prepared. Vehicles

2.6.5.7 Four-Speed Idle with One Spark Plug Disconnected

This test is the same as the Four-Speed Idle test in Section
2.6.6 except that one spark plug wire is disconnected during the test.

2.6.6 Commercial Repair

Those vehicles needing repairs were taken to commercial repair
facilities chosen at random from a listing of State qualified facilities.
The listing was obtained from the State Lane when a vehicle failed and addi-
tional listings were obtained from the State Bureau of Automotive Repair.
AESi employees took the vehicles to the State Lane and commercial repair
facilities as the owner's of the vehicles. No one facility was used to re-
pair more than two vehicles.

2.6.7 Underhood EGR Check

The underhood/EGR check in Step "F" of the Test Flow Chart in
Figure 2 is the same test performed in the initial screening except that no
plumbtesmo lead test was performed.

2.6.8 State Loaded Two-Mode

The State Loaded 2-Mode test that occurs after AESi repair and
before a cold start sequence is an AESi performed State Loaded 2-Mode test
as defined in paragraph 2.6.4 State Lane.

2.6.9 Low Emissions Tune Up

The Low Emissions Tune Up, appearing on the flow chart, consisted
of adjustments to IRPM, IHC, ICO, dwell and timing only. No other adjust-
ments, changes or modifications were performed at this step.

2.6.10 Evaporative Emissions Testing

Three vehicles, with failures in the evaporative emissions system
portion of the underhood check, received SHED testing. The SHED evaporative
emissions testing was performed in accordance with Federal Register test
Procedures and EPA requirements. The vehicles receiving SHED tests had
evaporative emissions tests as part of the cold start sequences in test num-
bers 3 and 6 only. All other cold start test sequences were FTP without
SHED tests.

2.6.41 After-Test Procedures

After the completion of testing and acceptance of the data by
Quality Assurance, each vehicle was taken to the inspection and maintenance
area. Here the mechanic measured and recorded engine parameters which
included initial timing, idle speed, undiluted idle CO and undiluted idle HC
emissions. When possible the procedures outlined in the owner's manual and

2.5.3 Sealed Housing for Evaporative Determinations (SHED)

The volume of the SHED used was determined by physical measure~
ment. Calibration of thermocouples used in the SHED was verified by an ASTM
thermometer as was the temperature recording instrument. Calibration curves
were generated for each range of the Beckman 400 FID used in the analytical
console. These curves were verified weekly.

For initial calibration, the FID was zeroed on zero grade prepur-
ified air and calibrated at two upscale points (i.e. 45% and 90% of full
scale) on each of the ranges used. The same hydrocarbon gas standards pre-
viously described were employed for this calibration. Curve fit tolerances
and verification frequency were the same as those applied to the dilute
emission analysis console instruments.

Tne SHED was subjected to a background hydrocarbon check, a cali-
bration check and a retention check prior to testing the first vehicle.

The background emissions check was performed by sealing the
enclosure and allowing it to remain sealed for a period of four hours.
Initial and final hydrocarbon readings were taken. The background emission
rate was acceptable when it was less than the maximum increase of 0.4 grams
for the four hours, as defined in 40 CFR Part 86.

The SHED was calibrated by first purging with fresh air and then
sealing the enclosure. Approximately 4 grams of instrument grade propane
was injected into the enclosure after the enclosure was sealed. The mixing
fans were operating during this injection. After five minutes of mixing,
the stabilized hydrocarbon level of the enclosure was measured and the mass
calculated. The quantity of the calculated recovery was within +2% of the
injected amount.

The propane retention (leak) check was performed following the
calibration. In this check the SHED was allowed to remain sealed for a min-
imum of four hours with the mixing blowers operating. At the end of this
period the hydrocarbon level of the enclosure was measured and the mass cal-
culated. For this check, the hydrocarbon level was within +4% of the ini-
tial reading as calculated. The SHED calibration and retention tests were
performed monthly thereafter.

2.5.4 ECE-50 Chassis Dynamometer

Dynamometer speed was verified initially and bi-weekly with a
Strobotach. Road load force was determined using calibrated weights.
Coastdowns were performed initially and bi-weekly thereafter to verify the
road load force versus inertia weight relationships as given in 40 CFR Part
86.

hydrocarbons, percent CO for carbon monoxide and ppm NO for nitric oxides.
Fuel consumption, in miles per gallon, was calculated from bag data accord-
ing to the carbon balance technique and reported for each vehicle. The car-
bon balance technique used was provided by the Project Officer.

All of the exhaust emissions data were calculated at the time of
test by the AESi DACC. This computer was checked at least monthly using
independent calculations from the analyzer strip charts to ensure its valid-
ity.

These results were reported on a weekly and a cumulative monthly
basis using the keypunched cards prepared for submittal to EPA.

2.723 Quality Control

The quality assurance program applied to this project monitored
every aspect of each emissions test. This included operator and driver per-
formance, the sampling system, ambient test conditions, analyzer perfor-
mance, gases, fuel, dynamometer settings and all data processing. In addi-
tion, all other data submitted as part of this project received the inspec-
tion of the Quality Assurance section. Any discrepancies noted during the
review process were resolved in an appropriate manner.

Figure 3 presents a flow chart of the Quality Assurance activi-
ties.

2.74 Calculation of Results

2.7.4.1 Federal Test Procedure

Test results were calculated based on the procedure presented in
4O CFR Part 86. Theoretical distance was used in the grams per mile calcu-
lation for each test phase. Fuel consumption was calculated using the car-
bon balance method and was reported in miles per gallon.

2.7.4.2 50 MPH Cruise

Emissions from the 50 MPH Cruise tests, performed with the veh-
icle on the dynamometer, consisted of a five second analyze time after
Stabilization of HC, CO and NO had occurred. The DACC collects ten readings
per second, averages them and prints the average value for each pollutant.

2.7.4.3 Highway Fuel Economy Test
HC, CO, COp and NOx were measured and reported in grams per
mile. The mass emissions were calculated according to 40 CFR Part 600.

Fuel economy was calculated by the carbon balance method and reported in
miles per gallon.

record was maintained for the ambient temperature in the soak and test areas
for all phases of testing. The vehicle soak area is inside the same build-
ing as is the test area and is free from precipitation.

2.4.2 Constant Volume Sampler

A positive displacement pump type constant volume sampler (CVS)
built by AESi was used in this program. This CVS meets or exceeds all spec-
ifications defined in the Code of Federal Regulations Title 40, Part 86,
Subparts A and B (40 CFR Part 86). The system contains six sample bags
switched by computer in sample/background pairs for all dilute exhaust
sample testing.

All plumbing in the sampling, analytical and calibration systems
is either stainless steel or teflon. This includes all sample, calibration
and zero gas lines and the valves and regulators for NO gases. Leak-tight
stainless steel convoluted tubing is used between the CVS and the vehicle
tail pipe for exhaust gas sampling. An appropriate leak-tight boot was used
to connect the tail pipe to the convoluted tubing. A stainless steel heat
exchanger with a temperature controlled cold water inlet was used to provide
essentially a constant exhaust gas temperature throughout the entire test.

The sample and dilution air bags are made of Dupont Tedlar mater-
dal and are of a volume compatible with the CVS unit (i.e., no pressure
build up in the bag when filling with sample or background gas).

204.3 Emission Analysis Console

An AESi exhaust gas analytical system meeting or exceeding the
specifications of 40 CFR Part 86, was used for dilute gas measurements.
Similar laboratory type instrumentation, with additional ranges, was used
for analysis of raw NO gas. In addition, a Chrysler Model III garage-type
analyzer was used for measurement of raw HC and CO. The console contains
the following instrument types and ranges:

Analyzer Ranges
Bendix Model 8501-5C NDIR
(Lo CO = Dilute Exhaust) 0-100, 0-500 ppm

(11 1/4" Cell Length)

were also solicited using news releases in local papers and paid
advertisements in newspapers and flyers.

2.3.2 Incentives for Participation

The owner of a suitable test vehicle was provided the following
incentives for his participation:

A $100 U.S. Savings Bond. Bonds were mailed to par-
ticipants within one month following the test on
their vehicle.

The use of a late-model, fully insured loaner auto-
mobile during the time their vehicle was undergoing
testing.

The owner's automobile was returned with a full tank
of fuel.

Owner's of vehicles that passed the initial screening
were given a tank of gas only.

2.363 Test Vehicle Handling

In most cases, the vehicle was scheduled to be delivered to AESi
in Westminster by appointment. In some cases, vehicles were picked up
and/or delivered at a participant's home or place of business. An inspec-
tion was performed to ensure proper vehicle match and to establish the phys-
ical condition of the vehicle. The owner remained at AESi during an initial
screening of the vehicle. This screening consisted of a tailpipe test for
the presence of lead, using plumbtesmo test paper, an underhood emissions
control component inspection, an EGR test and a four-mode idle emissions
test. Vehicles passing this screening were returned to the owner with a
full tank of gasoline. Vehicles failing this screening remained at AESi for
further testing. A loan vehicle exchange agreement, the savings bond appli-
cation and the Vehicle Owner Use Questionnaire were completed at this time.
Once the vehicle was accepted into the program it then followed the sequence
illustrated in Figure 2.

2.4 FACILITIES AND EQUIPMENT
2.4.1 Test Location

All tests were performed at AESi's test facility at 7300 Bolsa
Avenue in Westminster, California. The facility is located approximately 25
miles south of downtown Los Angeles at an elevation of 45 feet above sea
level.

The test facility environment, including testing and vehicle soak
areas, was maintained within the requirements of the contract. A permanent

on the vehicle's emission sticker were followed in performing these inspec-
tions. If the owner's manual and emissions sticker were missing, the shop
manual, or other available publication was used to determine vehicle speci-
fications. In some cases, the vehicle manufacturer was called upon to aid
in determining specifications.

2.6.11.1 Maladjustment and Disablement Inspection

Following test #3 or test #7 of the flow chart in Figure 2, all
venicles were given an extensive underhood inspection to determine the con-
dition and proper installation of each emission control component. Proce-
dures used were those detailed in manufacturers shop manuals. These proce-
dures were supplemented by other manufacturer supplied information where
necessary. The results of the many subsystem inspections were submitted to
EPA but are not listed in this report.

2.6.11.2 Fuel Tank

Prior to returning the vehicle to the owner, tire pressure was
set to manufacturer's specifications, and the fuel tank was filled to full
capacity with fuel currently being marketed in the test area. This fuel was
suitable for use in the particular vehicle.

2.6.12 Daily Test Schedule

Test shifts were generally limited to the first and second shifts
of the day. Vehicles scheduled for test the next day were usually precondi-
tioned on the second shift. Daily calibration checks and system preparation
(as described in Section 2.5) were performed prior to the first test of the
day and tests were scheduled with this in mind.

2.7 DATA HANDLING

2.7.1 Data Collection

Various forms were developed for the recording of significant
test information. These data forms are supported by various strip charts
and computer printouts from the AESi DACC. The forms were designed to en-
able direct keypunching in the formats defined by EPA.

The information included a thorough description of each test veh-
icle, its test results and inspection parameters, its driveability charac-
teristics and its use charateristics.

2.7.2 Data Processing

Diluted exhaust emissions test results include ambient tempera-
ture, barometric pressure, humidity, and mass equivalent (grams per mile) of
total HC, CO, COo, and of NOx both as-measured and corrected for relative
humidity. Undiluted exhaust emissions were recorded as ppm Hexane for

16


2.5.5 Data Acquisition System

The data acquisition system was verified by performing manual
checks of equipment performance and hand calculations from strip chart data
and comparing these with the data provided by the DACC. This activity was
verified by a Quality Assurance inspection for each test. A reasonableness
check is performed for each critical data element. Any suspect data was
verified by strip chart or calculation. Any data found to be in error was
independently recalculated wherever possible or the test was rejected.

2.5.6 Miscellaneous Equipment

All miscellaneous equipment was calibrated or verified according
to manufacturer's recommended practices. The CVS laminar flow element and
barometers were calibrated by Meriam Instruments Company.

2.6 TEST PROCEDURES
2.6.1 Vehicle Preparation

Each vehicle received a preliminary safety inspection as part of
the procurement activity. This was done to ensure that the vehicle was safe
to operate on the street. Upon acceptance for testing, the vehicle's fuel
tank was drained and refueled with appropriate test fuel to 40% of tank
capacity. Vehicles receiving a SHED test were further prepared by locating
a point on the side of the fuel tank that approximated the midpoint of the
40% fuel volume. A Type J thermocouple was then soldered to the tank at
that point. To ensure that test fuel had purged the fuel system, the veh-
dele was driven for ten minutes on city streets or on the dynamometer for
the first 505 seconds of the FIP. After the preconditioning run, the veh-
iele was driven or pushed into the soak area for the required 12 to 24 hour
soak at temperatures between 68°F and 86°F. Drive wheel tire pressure
was set to 45 psi prior to dynamometer testing to prevent tire damage.

Figure 2 presents a flow chart of testing activities.
2.6.1.1 Driveability Evaluation

An evaluation of the driveability of each vehicle was performed
prior to and during each FIP. The evaluation is essentially the same as
that performed on previous EPA light duty vehicle projects.

2.6.2 Equipment Preparation

Prior to the first test of the day and following any shut-down,
equipment which had been idle or in a stand-by condition was activated to
begin warm-up. This included the CVS water heater, mass pump and each of
the analytical instruments. Following the warm-up of the respective instru-
ments, efficiency of the NOx instrument thermal converter was checked and

2.5 EQUIPMENT QUALIFICATION, CALIBRATION AND CROSSCHECK

This section describes the qualification, calibration, and cross-
eheck procedures utilized by AESi and verified by EPA technical personnel to
ensure that valid test data were generated throughout the test program.
Initial qualification included complete demonstration of individual instru-
ment calibration, zero air and nitrogen purity, CVS calibration, dynamometer
calibration, and inspection of all daily, weekly and monthly logs.

2.5.1 Constant Volume Sampler

The CVS was calibrated with a laminar flow element (Meriam Model
50- MC2-6SF) using the basic procedures specified in the Federal Register.
CVS air flow, measured using the laminar flow element on the inlet side of
the mass pump (CVS blower) was controlled by throttling. Air flow rates
were measured at five incremental changes in pump differential pressure on
each side of the normal operating point. Flow rates at a total of at least
ten points were measured. The nominal air flow of the CVS is 345 cfm.
Auxiliary devices employed in the calibration included a mercury barometer
to measure absolute ambient pressure, a close tolerance mercury thermometer
to measure pump inlet air temperature, a U-tube water manometer to measure
pressure drop across the pump and pump inlet pressure and a close tolerance
inclined water manometer to measure pressure drop across the laminar flow

element. Once this calibration was completed, data from these devices were
computer processed and the mid-range blower operating point was determined.
Propane recovery tests using instrument grade propane were made after the
calibration to confirm its accuracy. A copy of the calibration data was
provided to the EPA Project Officer as a part of the qualification data
package.

Calibration of the laminar flow element (LFE) is traceable to the
National Bureau of Standards, and a certified copy of the LFE calibration
eurve was furnished to the Project Officer at the time of Laboratory Quali-
fication.

Daily propane recovery tests were made to confirm continued cali-
bration of the CVS system. The measured propane mass recovered by the CVS
had to be within +2.0 percent of the injected mass of up to 20 grams of
instrument grade propane as determined gravimetrically. The recovered
amount of propane was measured on the 0-300 ppmC FID range. A Rustrak chart
recorder was used to continuously record CVS temperature during these tests.

2.5.2 Emission Analysis Console

265-201 Dilute Exhaust Analysis Console

Gomplete calibrations of the mass emission analysis console
instruments were performed initially and checked each week thereafter until
testing was completed. Calibration curves for the mass emission analysis
console CO, COp, HC and NOx instruments were established using the gases
previously identified. The CO and CO. instruments were calibrated at
seven somewhat evenly spaced points (zero and six upscale points) across
each operating range. Calibration of the HC and NOx instruments was per-
formed at three somewhat evenly spaced points (zero and two upscale points)
across each operating range. Calibration of these instruments was estab-
lished and maintained within one percent of full scale for each range, re-
spectively, or five percent of the measured value, whichever was smaller. A
computer program provided by the EPA was used in the generation of the cali-
bration curves.

In connection with each test, the CVS sample bags were purged
with nitrogen, evacuated and leak-checked. These operations were performed
in a bag evacuate, No purge, evacuate and leak-check sequence by means of
a manual push-button selection of solenoids located within the CVS. A leak
in the system is indicated by a non-zero flow in the flow meters on the
operator's console.

Other activities included setting zero and span points immediate-
ly prior to exhaust sample analysis and zero and span point verifications
immediately following exhaust sample analysis. Strip chart recorders were
operated continuously throughout the zero and span set-point calibration,
sample analysis and zero and span verification sequence. Verification
tolerances were maintained within +1 deflection from the set-point for the

2.6.5 Cold Start Sequence

The Cold Start testing sequence included a 1975 Federal Test Pro-
cedure (FTP) cold start test, a 50 MPH Cruise test, a Highway Fuel Ecnomy
test (HFET), a Four-Speed Idle test, a Federal Loaded 2-Mode test, a State
Loaded 2-Mode test (at specified loads*) and a Four-Speed Idle test with one
spark plug wire disconnected. This test sequence was performed following a
State Lane test or following any AESi repair work on the vehicle.

2.6.51 Federal Exhaust Emission Test Procedure

The Federal Test Procedure as described in 40 CFR Part 86 was
performed on all vehicles in the as-received condition. The evaporative
emissions portion of the procedure was performed on 3 vehicles in this pro-
gram. The exhaust emission portion of the Federal Test Procedure is com-
prised of cold transient, cold stabilized and hot transient phases. The
cold transient portion is 505 seconds long, covering a distance of 3.59
miles with an average speed of 25.6 mph. The cold stabilized portion is 869
seconds in length, 3.91 miles in distance and a 16.2 mph average speed. The
hot transient portion is identical to the cold transient portion except that
it is preceded by a 10 minute soak. The evaporative emissions testing con-
sisted of a diurnal heat build as described in 40 CFR Part 86 paragraph
86.133-78. This was followed by FTP testing and a Hot Soak test per 40 CFR
Paragraph 86.138-78.

The cold soak period used for the test vehicles was 12 to 24
hours. The starting procedures and shift points used for the test vehicles
were as recommended by each manufacturer.

2.6.5.2 50 MPH Cruise

This test takes advantage of the 3 minute preconditioning run
before the HFET. Tailpipe emissions are recorded and measured continuously
throughout the period although the official sampling period ends 30 seconds
after the speed and load have stabilized at 50 MPH.

*NOTE: 10.0 AHP +1.0 4 Cylinders or less
15.0 AHP +1.0 5 or 6 Cylinders
17.5 AHP +1.5 8 Cylinders less than 3250 lbs

2.6.5.3 Highway Fuel Economy Test

Starting with each vehicle in a warmed-up condition (at least 7.5
miles of cyclic operation within the last thirty-five minutes) each vehicle
was operated on the chassis dynamometer at 50 miles per hour for three min-
utes. Within one minute after the end of the 50 mile per hour cruise per-
dod, the vehicle commenced operation over the 10.242 mile, 765 second driv-
ing schedule. A CVS sample bag was used to gather the dilute exhaust for
emissions analysis and fuel economy calculations. HC, CO, COg and NOx

2.7.4.4 Four-Speed Idle Emissions Test

Emissions from the Four-Speed Idle tests, performed with the veh-
icle on the dynamometer, consisted of a five second analyze time after
stabilization of HC, CO and NO had occurred. The DACC collects ten readings
per second, averages them and prints the average value for each pollutant.
This procedure was followed for each test mode.

emissions were measured and reported in grams per mile. Fuel economy was
calculated by the carbon balance method and reported in miles per gallon.

2.6.5.4 Four-Speed Idle Test

This test followed the HFET and required additional analytical
instruments, aside from those required for the basic FTP test, to measure
undiluted exhaust emissions. The instruments used for measurement of undi-
luted HC, CO and NO emissions are specified in Section 2.4.3.

This short test consisted of volumetric sampling of undiluted
exhaust emissions during four steady state operating conditions, with the
hood open and the cooling fan on. The first operating mode was basic idle
with the transmission in neutral. The second operating mode was at 2500
engine RPM, also in neutral. The third mode was again normal curb idle in
neutral and the fourth mode (automatic transmission vehicles only) was curb
idle in Drive with brakes applied.

Four-Speed Idle tests were preceded by a six minute idle soak
period with transmission in neutral, the hood open and the auxiliary cooling
fan on. At the end of the soak period the vehicle was operated at idle in
neutral, then at 2500 RPM, again at idle in neutral and then idle in Drive
for automatic transmission vehicles. Equilibrium of engine speed and the
CO, HC and NO analyzer output meters was maintained for 30 seconds before
the readings were recorded. CO, HC and NO were measured and reported in
percent CO, ppm Hexane and ppm NO respectively. Engine RPM from the last
idle mode was written on the vehicle data packet.

2.6.5.5 Federal Loaded Two Mode Test

The six minute soak period and the undiluted exhaust analysis
instruments described under the Four-Speed Idle test were also used for this
test. This test followed the HFET and Four-Speed Idle Test so the engine,
dynamometer and analyzers were at normal operating temperature. Inertia
weight was set at 1750 pounds. The dynamometer load was set to 9.0 actual
horsepower at 30 miles per hour regardless of vehicle weight. Using Drive
for automatic and third gear for manual transmissions, the vehicle was oper-
ated at 30 miles per hour roll speed. The concentrations of HC, CO and NO
emissions were recorded continuously during this time and analyzed after a
maximum of 30 seconds or when stabilized. Following this, the vehicle was
allowed to idle until emissions once again stabilized or for a maximum of 30
seconds before the concentrations were again analyzed.

2.6.5.6 State Loaded Two-Mode
This test is based on the Loaded Two-Mode test performed at the
State Lane inspection stations. The test consists of a 40 MPH cruise as

defined in paragraph 2.6.4 State Lane Inspection and an idle in neutral.
Undiluted HC, CO and NO emissions were recorded at each stage of the test.

SECTION 1
INTRODUCTION

The U.S. Environmental Protection Agency (EPA), through authority
provided by the Clean Air Act, is responsible for the control and prevention
of air pollution. As provided by the Act, one of the charges of the EPA is
the design, conduct and promotion of surveys and studies of the sources of
air pollution. The Emission Control Technology Division (ECTD) of the EPA
develops, implements and administers a national program to characterize,
quantify and reduce the air pollution caused by mobile sources. Included in
the division's responsibilities is the collection of emissions data from
in-use vehicles and the development and evaluation of alternatives for the
control of vehicle emissions. These in-use vehicle data are utilized by the
EPA in calculating and projecting motor vehicle emissions from light-duty
vehicles. The emission factors generated by this process are also used in
developing transportation control procedures and contingency programs to
cover emergency situations. Outside of the EPA, these data and the emission
control alternatives are used by various state and local agencies in their
air pollution control programs. In carrying out its responsibilities, the
EPA regularly conducts in-use vehicle emission factors programs and emission
control alternative studies. In order to support the states in their
efforts to implement their air quality programs, the Emission Control Tech-
nology Division will use the data generated by this project to assess the

effectiveness of new technology vehicle exhaust emissions systems in Los
Angeles.

This report describes a program conducted by Automotive Environ-
mental Systems, (AESi) to gather information on the effectiveness of south
coast air basin change of ownership I/M program. The testing was conducted
between August 1980 and October 1980.

Section 2 of this report describes the objectives, design, and
conduct of the program. Section 3 presents summary results. Detailed list-
ings of data are presented in the Appendices by vehicle number. Data pack-
ets and punched computer cards, with EPA-defined data formats, were sub-
mitted to the Project Officer.
