ABSTRACT

This paper  describes  Che results  of  an exhaust emission  testing program
conducted  on forty  1981 passenger  cars.   The primary  purpose of  this
program  was   to  examine   the   emission  performance  of   high-mileage
vehicles.   Secondary  objectives  included an  assessment of  the condition
and performance  of  the  emission-related components and the  collection of
information  for  development and  improvement  of I/M  programs.   The  work
was  performed  by   Automotive    Testing   Laboratories   (ATL)  at   the
Transportation Research Center in East Liberty, Ohio.

The test  vehicles were  drawn  from the  general public  in  the Columbus,
Ohio area using  direct mail  solicitation.   Only vehicles with over 60,000
miles were  sought.  This  resulted in  an average odometer  reading for the
fleet  of   71,410.    The  tests   performed  included   the   Federal  Test
Procedure,  the  Highway Fuel Economy  Test  and  several short  tests.   The
program began in July, 1983 and was completed in November,  1983.

The results of  this  program  indicate  that  some  of  these   vehicles  are
capable of  maintaining  low  emission levels although high  levels are  also
possible  due  to   emission  control   component  failure,   engine   wear,
deterioration  and  tampering*   The average  emission   test   results  were
significantly higher  than the standards  under  which  they were certified
and somewhat  higher  than the  averages of  comparable  in-use  vehicles at
lower mileages.   The data  indicate  80%,  127,  and  45% of  the  cars  were
above the  Federal  standards for  HC,  CO,  and  NOX,  respectively  and  35%,
35%  and   15%  exceeded  twice   the   standards  for   HC,   CO  and  NOX,
respectively.  City and Highway fuel  economy  values were also found to be
lower than those published in the 1981 Gas Mileage Guide.

Introduction

Few data  are currently  available on late  model,  in-use  vehicles  beyond
the 50,000  mile "useful  life"  defined  by  Federal  Regulations.   Because
approximately half  of  the  passenger cars  registered  today have  passed
that point, this category of  vehicles has a significant impact  on ambient
air quality.  In  this project,  emission data  were collected on  a  sample
of  1981  model year  vehicles  which have  exceeded  60,000  odometer  miles.
The test  results  will  be used to  support estimates  of  future  emission
levels from vehicles with this type of control technology.

Purpose

The purpose of this program was four-fold:

    1.   To gather advanced information on  high mileage vehicles  in order
         to  better   predict  future  emissions  from  vehicles  which  have
         accumulated mileage at a more normal rate.

    2.   To identify  weaknesses  and potential  failure areas in  emission
         control  systems so  that  the   effectiveness   of  the  regulatory
         process can be enhanced.

    3.   To  provide  information  for  development  and  improvement  of
         inspection/maintenance programs.

    4.   To provide  information regarding  the  capability of  restorative
         maintenance to reduce emission levels.

Program Design

This work  was performed by Automotive  Testing Laboratories (ATL)  at the
Transportation  Research  Center .  of  Ohio   under   EPA  Contract   No.
68-03-3157.  Forty vehicles of the 1981 model  year with over 60,000 miles
were sought at  random from  a  direct mailing.  The vehicles  selected were
in  customer  use   and  were   tested   "as-received"   in  order  to  reflect
differences  in  usage,  maintenance  and  repair.   Vehicles  which  failed
their as-received test  by over  200% received an R/M sequence.   Names and
addresses  of  owners  of 1981 model  year passenger  cars  in the area  of
Columbus, Ohio  were  purchased from R.L.  Polk  Co.   Solicitation  packages
were mailed to 6,162 owners at random.  The package  included a  letter and
a postpaid  reply  card with which an owner could  report  certain vehicle
information and express his willingness to participate.  A copy of this
package is  included  as  Appendix A.   Since  we  were  seeking  vehicles with
the  highest  mileage,  ATL  ranked  the  positive  responses  by  odometer
reading.     No  attempt  was  made to  procure  a  sample  which  represented
national  sales.   Owners of  vehicles  with  the  highest  readings  were
contacted and offered an incentive package consisting of a  $100 Savings
Bond,  a  loan  car  and a  full  tank of fuel  upon return  of  their  vehicle.
ATL also offered to  exchange  cars at  the  owner's  convenience and promised
a summary of the test results on their vehicle:.

-------
At  the  initial meeting,  the principal  driver was  asked  to complete  a
short questionnaire and fill out several forms related  to  the exchange of
vehicles.  Examples of these are included as Appendix B.

Once  each  vehicle  was  acquired,  an  AIL  technician  prepared  it  for
testing*  Fluid levels  were checked and corrected but  no  other  underhood
activities were conducted.  A sample of the  drained  fuel was  analyzed for
lead content.  Preconditioning  consisted  of the  first  505  seconds  of the
Federal  Driving  Cycle on  the  dynamometer  or  driving  for  10 minutes  on
city streets.  This was followed by a 12-24 hour  soak period.

Each vehicle was tested as-received in the following  sequence:

    1.   Federal  Test  Procedure  (without  heat-build  or  measurement  of
         evaporative emissions).

    2.   "Bagged  Idle"  test.   During  this  three minute   idle  test  the
         exhaust  emissions  are  gathered   through   the  CVS.   The  FTP
         instruments are used to analyze the diluted  sample.

    3.   "50  MPH   Cruise"   Test.    This   short   cycle  employs   garage
         instruments  to measure  tailpipe  concentrations   of  HC  and  CO
         during the 50 mph preconditioning for the HFET.

    4.   Highway Fuel Economy Test.

    5.   Four-Mode  Idle Test.   This  short  test is   comprised  of  four
         steady state modes:  Idle  in  neutral, 2500 rpm in neutral, idle
         in neutral,  and  idle in drive.   Garage  instruments  are used  to
         sample tailpipe concentrations of HC and CO  for each  mode.

    6.   Loaded Two-Mode  Test.   Sampling  is done  as before  using  garage
         instruments.  The  first mode  is  30 mph  at  9  actual dynamometer
         horsepower.  The  second mode is idle in  neutral.

    7.   Restart  Idle  Test.  This  idle test  consists of  two  operating
         modes.  At  the  end of  the  6-minute Idle period,  the engine  is
         shut  off.   The  vehicle   is   immediately  restarted using  the
         hot-start  procedure  and the  engine  is  brought  up  to  2500  rpm
         (+300  rpm).   Emissions  are measured within  30  seconds.   The
         engine is  then returned to idle  neutral and  idle emissions  are
         measured  within  30  seconds.   Garage instruments  are  used  to
         sample tailpipe concentrations of  HC and  CO  for each  mode.

    8.   A complete underhood inspection was performed  after  the  emission
         tests.

    9.   Vehicles  which  failed their  as-received emission  test  by  over
         200% received restorative  maintenance and were retested.

-------
The  FTP and  HFET data  are  used  for comparison  with  certified emission
levels  and  to help project  future levels of  air quality  due to vehicles
of  the  1981  model  year.   The  inspections  and  short  cycles  provide
information   for  development  and  improvement:  of  Inspection/Maintenance
programs.
Results

The  program  began  in  July,  1983.   It  was  conducted  sucessfully
accordance with  the design and was completed in November, 1983.
                                       in
Of the  6,162 solicitation packages sent out,  responses were received from
3004 owners.   This, total of 49 percent was  11 percent  higher  than in our
1980 model  year vehicle program  but  consistent with  the  approximately 50
percent   response  rate  experienced   in   other  similar   programs.   No
follow-ups,  either  by mail  or  phone,  were  part of the plan.

Figure   1  displays  the  number  and  type   of   responses  versus  time.
Eighty-two  percent  of  the  responses were received within  nine days of the
mailing.  Of the total  responses, 66  percent indicated a willingness to
participate in our  program, although, because  of  the  mileage requirement,
only  one  percent  were  both  willing and  able  to  participate.    Only
acceptable  vehicles with  over 60,000  miles were  tested   with  an average
odometer  reading  for_ the fleet of 71,410.

Although  no  attempt  was  made  to  procure  a   sample  which  represented
national  sales,   the  fleet  tested   reasonably  reflects  the  national
population  for the  1981  model year  as reported by the  Automotive News.
While   there  were   some   shortages   of   General   Motors,   Ford,  and
miscellaneous  imports and an  over-representation of Chrysler,  Toyota and

-------
Honda these were probably due  to  the  relative strengths of dealers In the
Columbus area.  Table 1 presents the sample share versus the market share.

Miles-per-gallon   (mpg)   figures  for   both  the   FTP   and   HFET  were
calculated.   The  average  fuel economy  was compared  to  the  appropriate
values  listed in  EPA's  1981  Gas Mileage  Guide.   Figures 5  and  6  are
histograms of fuel economy as  a  percent  of  guide value.   The distribution
of the values appear  to  be reasonable and  consistent  with the  results of
earlier work.

Idle vs. FTP Emissions

As can be expected, there was  a  reasonable  correlation between results of
the FTP and  the results  of the  idle  test.   Shown in  Figures 7  and 8 are
plots of FTP  emission levels  versus  results of a  basic  idle test.  Using
the typical cutpoints of 250 ppm  for HC  and 2.5%  for CO, Table 3 displays
the amount of  excess  FTP emissions  identified  by the Idle Test.   Excess
emissions are the amount of FTP emissions above certification levels.

Underhood Inspection

Each of the vehicles was  tested  in "as-received"  condition to gather data
representative  of  normal  use.   An  underhood  inspection  of  emission
related  components  and adjustments  was  also  conducted  to  evaluate  the
degree  of  any  maladjustments,   disablements,   inadequate  maintenance,
defects,  unusual  deterioration  or  misbuilds.   Any  abnormal  physical
condition or  a  measured value outside an  allowable  range was  coded  as a
failure.

Results from  past  programs have shown  that  vehicles which  are in proper
operating order normally  produce the lowest emission  levels.   Six of the
vehicles  in this effort  were found  to  be in  proper  order  and  although
only two  passed  their  emission  standards, all  six were  low emitters.   A
summary of  these  findings is  contained  in Appendix D.   Typical  problems
include basic timing,  idle speed,  choke settings, PCV valve plugging and
EGR tampering.

Misfueling

Fuel  samples  were  drawn from each of  the  vehicles and  examined  for lead
content.   In addition,  filler  necks  were  examined  and  the  PLUMBTESMO
(lead sensitive  paper  applied to the  tailpipe)  test  was conducted.  None
of  the vehicles  were found to show  positive signs of using  leaded fuel.
No  filler  necks were  found  to be  altered.-   This   was  not  considered
unusual in  that  the  proportion of all vehicles  which have been aisfueled
might not be properly represented in a voluntary program sponsored by EPA.

Comparison With Results of Other Programs

EPA  has  conducted  several test  programs  which sampled  comparable  1981
models.  During  these  earlier programs,  367 vehicles  from the  1981 model
year were tested.  The  average mileage for  this sample  was.11,133 miles.
Of  this  sample,   56% met  their  standard  with  average  HC and CO levels
slightly  above  the  standard.   Average   NOX  emissions  were  below  the
standard.  These results are  listed in Table 4 and are plotted in Figures
9-11.

Other results were  obtained from recent programs  known as EF-I  & EF-II.
These programs included 366 vehicles  from the 1981 model year which were
tested at EPA's Ann  Arbor  facility.  A random sample  drawn from within 20
miles of Ann  Arbor was  obtained using the  State of Michigan registration
list.  The  testing was  completed in 1983.   Results from this program are
also listed in Table 4 and plotted in Figures 9-11.

As  can be  seen  from  Table  4,  the  averago emission   levels  of  these
vehicles  show a definite  trend  toward  higher levels  as  the  vehicles
accumulate mileage.  Restorative maintenance indicated the primary causes
for these differences can  be  attributed to deterioration of the engine or
problems with the control systems.

Conclusions

The  results  of  this  program  indicate  that  some  of  these vehicles  are
capable of maintaining  low emission levels although high  levels  are also
possible  due  to   emission  control  component  failure,   engine   wear,
deterioration and tampering*   The  average emission test results  of  these
high-mileage 1981 models  were significantly  higher  than  those  resulting
from  the  EPA  Certification tests.  Considering  the  results  from  other
studies on  1981 models at  lower  mileage, there  is also  a clear  trend
toward increasing emission levels with  age,  mileage  and   the  associated
degradation of  components and adjustments.   The  data  indicate  80%,  72%
and  45%  of  the  cars  were  above  the Federal  standards for HC,  CO,  and
NOx,  respectively  and   only  35%,   35%  and  15%  exceeded   twice  the
standards  for  HC,  CO,  and  NOX,  respectively.   City  and  Highway  fuel
economy values  were  also  found   to  be  significantly  lower  than  those
published in the 1981 Gas Mileage Guide.

 Dear Vehicle Owner
The Environmental Protection Agency is conducting an important air pollution
study. The actual work will be performed under contract by Automotive Testing
Laboratories (ATL) at the Transportation Research Center of Ohio. You have
been selected as a possible participant in this program, in which an official EPA
fuel economy and emissions test would be performed on your vehicle. You may
be able to help us and be rewarded for your cooperation.
Our current program involves 1981 vehicles with high odometer readings.
If your vehicle qualifies, we will offer you the following incentives to
participate:
     1.  The use of a late-model, fully insured loaner car with a full tank of fuel.
        We will exchange vehicles at a time and place of your choice.
    2.  A $100 U.S. Savings Bond.
    3.  Return of your vehicle with a full tank of fuel.
    4.  The results of the emission and fuel economy tests.
No unusual operations will be performed on your vehicle and it will be fully
insured for the entire test period, which will take approximately one week. If
you are willing to participate, a representative of ATL will be in touch with you
to ask questions about your vehicle.
Please complete and return the enclosed postpaid reply card as soon as pos-
sible, even if you choose not to participate or if your odometer reading is not
high. Other programs are planned for which you may be eligible.
The enclosed information sheet answers questions people often ask about this
program. If you have any additional questions, please feel free to call Priscilla
Bruce of ATL at 221-0336 or John Shelton of my staff at (313) 668-4200. They will
be able to answer any questions you may have.
We look forward to receiving your reply card or a telephone call very soon.
Sincerely,
 Ralph C. Stahman, Chief
 Test and Evaluation Branch

                                                               AlP. NOISC ANO "AQlAT'CN
                       Questions and Answers

1.  Must I participate In this program?

    No, your cooperation in this program is completely voluntary. If, for any reason,
    you decide not to participate, please let us know on the enclosed postpaid reply
    card.
2.  Why should I participate?

    In addition to a $100.00 U.S. Savings Bond, a leaner vehicle and a full tank of
    gasoline, your participation will benefit you indirectly by helping EPA under-
    stand and improve the quality of the air in and around your city.


3.  How long will the test program take?

    The test program takes approximately 1 week. The length of time is dependent
    on how many other cars are being tested.


4.  Will my vehicle be mistreated in any way?

    No, every aspect of the test program has been designed to duplicate everyday
    operation.


5.  Exactly what will be done to my vehicle?

    A complete underhood inspection will  be performed. The vehicle must be
    commpletely cooled off before the test can begin. This requires that the vehicle
    not be started for 12 to 36 hours to simulate overnight parking. Once the vehicle
    is sufficiently cooled off, it will be pushed onto  a dynamometer. Although the
    vehicle doesn't actually move during  the test, the dynamometer is a type  of
    treadmill which simulates conditions which  would normally be encountered on
    the road. A hose is connected to the exhaust pipe to  collect the exhaust. A
    specially trained driver then starts the vehicle and "drives" it through a "driving
    cycle" which represents typical operation in urban,  suburban and rural areas.
    Throughout this time, a portion of the exhaust gases is collected for subsequent
    exhaust analysis. This analysis allows us to calculate the quantity of exhaust
    emissions emitted by your vehicle. Values for the city and highway fuel economy
    are also calculated.

 8.  How many milts wilt my vehicle bt driven during the program?

    Your vehicle will be driven approximately 100 odometer miles during the testing.
    The majority of these miles will be accumulated indoors on the dynamometer. A
    10 minute road test might precede the dynamometer testing.


 7.  How will my vehicle be protected while in your possession?

    In addition to providing insurance, we will store your vehicle indoors while the
    testing is being conducted. If required to be parked outside, your vehicle will be
    located in a locked and secure area at ATL's Motor Vehicle Emission Laboratory
    which is located at the Ohio Transportation Research Center in East Liberty, Ohio.


 3.  What happens to the information obtained from my vehicle?

    The information collected as a result of this program is used to determine the
    emissions performance of in-use vehicles and its effect on air quality. The data
    from your vehicle are combined with data from other vehicles in this area in order
    to obtain a statistically valid sample.


 9.  How can I obtain the results from the testing of my vehicle?

    If you request, after the completion of the testing you can obtain the results on
    your vehicle. We will forward them to you as soon as all the data have been pro-
    cessed.


10.  What happens if my vehicle fails to meet any emission standards?

    We expect that a certain proportion of the vehicles will fail to meet one or more of
    the emission standards. However, none of  the information collected  from this
    program will be used against individual vehicle owners.
