                              ABSTRACT
       A group of 50 trucks,  of model years 1965 to 1973, 6, 000 to
16, 000 Ibs gross vehicle weight were tested for exhaust and  evaporative
emissions  using a modified light duty procedure.  The results from these
tests, together with other  similar tests initiated by the Environmental
Protection Agency, wjill form the baseline emissions data for this test
procedure.  The group of trucks which was assembled for these  tests was
sufficiently varied to contribute to  a proper baseline.  All trucks completed
the test procedure successfully,  however,  it appears that some adjustment
in road load power  settings may be  required at dynamometer inertia set-
tings above 8,500 Ibs.

                          I.   INTRODUCTION
       According to the latest statistical information(l)*, trucks comprise
about 17  percent  of the  total vehicles registered and burn approximately 28
percent of gasoline consumed in the United States.  Approximately 56 per-
cent of all trucks now classed as heavy duty (that is, above 6, 000 Ibs gross
vehicle weight) are in the 6, 000 to  16, 000 Ibs gross vehicle weight (GVW)
class.

       This report covers the emission testing of 50 vehicles in the 6, 000
to 16, 000 Ibs GVW class for the purpose of confirming the test procedure
used and obtaining baseline emissions data. As it draws heavily on  the
knowledge and experience gained in previous projects with heavy duty vehicles,
a brief review of these  projects is  presented here.

A.     Previous  Projects

       Southwest Research Institute's Emissions Research Laboratory has
been privileged to have conducted a major portion of the  research done on
heavy duty vehicles beginning in June  1967.  This first effort was the acqui-
sition of baseline emissions data from 150 gasoline and LPG  fueled  spark-
ignited, engine-powered trucks and buses using three experimental  road-
like chassis dynamometer procedures.  Exhaust emissions for this  project
were  obtained using a special truck version of the constant volume sampler
(CVS) which permitted expression of contaminants on a mass basis.  The
results of the survey are  contained in the  SwRI final report(^) which conceded
that the three proposed experimental nonconstant speed cycles were not rec-
ommended for use in testing emissions from heavy  duty vehicles powered by
spark-ignited engines.  The findings of this study were summarized in  AlChE
and SAE  papers'^' "*' which described  the preparations and baseline  data
results,  respectively.

       The second major work in this continuing program compared hydro-
carbon (HC), carbon monoxide (CO), and nitric oxide (NO) emissions obtained
in actual road driving to chassis dynamometer  emissions obtained using the
Federal nine-mode constant speed cycle (FTP) for six trucks of various sizes
and makes.  Using  a CVS, the current Federal cycle was subjected  to a num-
ber of modifications to  investigate  what improvements might  be  made to
make the Federal procedure agree more  with road operation^'.

       The third in this series of projects, sponsored by the Environmental
Protection Agency (EPA) was completed in April 1972 ("). The first phase of
* Superscript numbers in parentheses refer to the List of References at
the end of this report.

-------
this three-phase project was a broad emission characterization study of
four 1969 trucks under a wide variety of engine speeds,  power  levels,  and
both stationary and chassis-operated engines.  Emission rates  of hydro-
carbons,  carbon monoxide,  and nitric oxide were expressed in  mass units
of grams per minute,  per pound of fuel  and per bhp-hr.   In addition to the
steady-state emission maps, a number  of transient accelerations and decel-
erations were studied using a variety of simulated vehicle inertias.  The
second phase was a four-vehicle study of the effect of four different road
routes on emission rates.  The road  routes were  sufficiently different to
be distinct, yet were considered representative of actual truck  driving.

        The study of actual on-the-road  exhaust emission rates  was con-
tinued in a fourth project in which 25  trucks were driven over the San
Antonio Road Route while  collecting exhaust emission samples  with a CVS.
Three of these trucks,  ranging from  10, 000 to 19, 500 Ibs GVW were also
operated, without problems,  on a  chassis dynamometer using the Federal
light duty driving schedule.   It is with this background in operation of the
CVS on that this project was  undertaken.
B.     Scope

       This  report covers the exhaust and evaporative emission testing of
50 vehicles in the 6, 000 to 16, 000 Ibs GVW categories at Southwest Research
Institute.  This  represents  only about one-third of the trucks constituting
the Environmental Protection Agency's Intermediate  Duty baseline fleet.
The remaining vehicles  were tested by another contractor and in-house
by the EPA.

       About mid-way through the testing phase of the contract, it became
apparent that the road load  horsepower table values used for the baseline
testing were too high at  high gross vehicle weights (in excess of 9, 000 Ibs).
As  a temporary solution to  the problem, it was decided by the Project Of-
ficer that for vehicles with  test inertia weights above 8, 500 Ibs, the  road
load horsepower corresponding to 8, 5000 Ibs would be used.  It was  also
decided that, if possible, additional high GVW vehicles should be tested
to determine road load horsepower at vehicle weights above  8, 000 Ibs.
Since one of  the last of the 50 baseline vehicles was an 11, 000 Ibs GVW Win-
nebago Motor Home ideally suited for this testing, road horsepower  was
determined at several vehicle weights and additional  exhaust emission tests
run at various inertia weight settings  on this vehicle.  Since as much road
horsepower information  as  possible was desired at these higher inertia
weights and since some  time was  available after completing  the 50 truck
baseline  tests,  an additional truck was obtained for road load horsepower
testing.  The results of  the series of tests on these two vehicles is also
covered in this report.

-------
                   II.  OBJECTIVE AND APPROACH
A.     Objective

       The objective of this project was to determine the exhaust and
evaporative emissions  on a group of 6, 000 to 16, 000 Ibs GVW vehicles
using a modified light duty test procedure.  The test results will form
the baseline for this procedure.  A secondary objective was  to confirm
that the procedure was  workable over the  entire range of vehicles considered.

B.     Approach

       To meet the project objective, it was decided to test  150 trucks fal-
ling within the desired  GVW range. For its portion of the project, SwRI
would test 50 trucks.  The procedure  used would be the light duty Federal
certification procedure, except that the inertia weight  and road horsepower
settings would not be those  listed in the Federal Regulations for light  duty
vehicles.   Inertia weight settings and  road load horsepower settings were
to be provided by the Procedures Development Branch of the EPA.  The
fleet composition was also to be determined by the  Procedures Development
Branch to reflect actual trucks in service over a number of years.

       Trucks  prior  to the  1972 model year were to be tested with timing,
idle speed,  dwell and carburetor settings  as received.  Trucks of model
year 1972 and 1973 were to be tested as received and if not within factory
specifications,  set to specifications and retested.

C.     Project Co-ordination and Inspections

       Project co-ordination began immediately after  notification of the
acceptance  by the EPA  of SwRI to perform a portion of the project.  A
meeting was held at the EPA's.Mobile Sources Pollution Control  Laboratory,
Ann Arbor, Michigan on November 16 and 17, 1972.  At this meeting, at-
tended by SwRI and the  other contractor involved in the project, the fol-
lowing items were agreed upon:

       1.  The one hour precondition  road run would be  replaced
       by one complete 23-minute  driving cycle on the chassis dyna-
       mometer.

       2.  Curb weight would be defined as the unloaded weight of
       the complete vehicle without owner added accessories or
       payload.

       3.  Gross vehicle weight used  would be that stamped  on the
       manufacturer's  vehicle identification plate.

-------
       4.  Payload would be defined as GVW minus curb weight.

       5.  Test weight would be calculated as follows:
           Test weight = curb weight+500 Ibs (0-2000 Ibs payload)
           Test weight = curb weight+1000 Ibs (2001-4000 Ibs payload)
           Test weight = curb weight+1500 Ibs (greater than 4000 Ibs
              payload)

       6.  For 1972 and 1973 vehicles to determine if a vehicle was
       within specifications,  the manufacturers tolerances will be
       used.

       7.  Model years to be tested will be 1965 to 1973.

       8.  The contractors would provide  the EPA with copies  of the
       original data sheets and computer cards with test results  in
       an agreed upon format.

       From this meeting onward throughout the period of the contract,
close contact was maintained by telephone between SwRI and EPA represent-
atives working on this project.  In addition to the numerous telephone con-
versations,  EPA representatives visited the Emissions Research Laboratory
at SwRI on three occasions during the contract period.  From January 16 to
19, 1973, Mr. John Shelton of the EPA conducted a formal inspection of the
laboratory.  On  February 26 and 27, 1973,  Messrs.  Preben Ostberg, Marty
Reineman, and Tom Snyder of EPA  visited the Emissions Research  Lab-
oratory for an informal inspection and project review.  On April  5,  1973
Mr.  G.  E. Douyard made an informal inspection of the laboratory.

          III.  TEST FACILITY, EQUIPMENT AND PROCEDURE
 A.      Test Facility

        The testing associated with this project was conducted at the SwRI
 Emissions Research Laboratory.  This laboratory, shown on the frontis-
 piece,  is equipped for controlled-environment operations with the most
 modern means of emissions sampling and analysis.

        The soak area and chassis dynamometers used in this project are
 located in one of the laboratory high bay areas.  There is ample room in
 this area for four trucks plus  all the equipment  and instrumentation required
 for both CVS exhaust emission tests and canister type evaporative emission
 tests.  The approximate 100 tons of air conditioning and heating servicing
 this high bay area is capable of maintaining the  temperature  in the  labo-
 ratory  at the required 76" to 86° F over the entire range of outside  tem-
 perature.  Figure 1 shows  portions of the high bay area.

 B.      Test Equipment  and Instrumentation

        1.  Exhaust Emissions Sampling and Analysis

        The exhaust sampling and analysis  equipment are built to EPA spec-
 ifications as shown in the Federal Register, Volume 37, No.  221,  Paragraph
 85. 075-20.   For easy reference,  Appendix B  contains a reprint of the Fed-
 eral Register sections pertinent to this project.

        The constant volume sampler (CVS) used on this  project was built
 by SwRI to EPA specifications.  It features  a  Roots 251OJ  "Whispair" rotary
 positive displacement blower.  The blower is  driven by a 5 hp electric
 motor using  a Browning gearbelt.  This arrangement allows the blower
to accurately be driven at various  speeds by the use of different pulleys.
During  this  project two different blower speeds were used. For the major
portion of the testing, a speed of 3880 rpm with a corresponding inlet vol-
ume flow of approximately 310 SCFM was used.  During the latter portion
of the testing, the blower speed was increased to 4850 rpm giving a blower
inlet airflow of approximately  360 SCFM.   The diluted exhaust gas mixture
is maintained at a temperature of 110°F at the blower  inlet by a water-to-
gas, shell and tube heat  exchanger.  The dilute  exhaust gas and background
samples are extracted at the rate of approximately 10  SCFH.   The blower
inlet pressure and blower pressure rise are read using Dwyer "Magnehelic"
pressure gages.  The blower inlet temperature is  recorded on a strip chart
recorder to provide a permanent record.

        The analytical instrument train was assembled by SwRI and  plumbed
to EPA  specifications.   The analytical instruments in the train are:  two

       2.  Chassis Dynamometers

       Two chassis dynamometers were utilized during this project.  Both
dynamometers were modified Model CT-200,  Clayton dynamometers located
in the same high bay area.  One dynamometer had continuous rollers with
an inertia capability of 9,500 Ibs.  The second dynamometer had split rol-
lers with a capability to handle trucks with a wider wheel track and an inertia
capability of 13,500 Ibs.  The smaller dynamometer, designated dynamometer
No. 1, was equipped with a Clayton supplied inertia system.  The larger
capacity dynamometer,  designated dynamometer No. 2,  had a SwRI designed
and built inertia system.  This inertia system was calibrated against the
system on dynamometer No.  1 to insure  compatable results.

       3.  Miscellaneous Equipment and Instrumentation

       Table 1 lists the other pertinent  instrumentation and equipment
used in connection with the tests, together with its manufacturer and use.

C.     Vehicles Tested

       A total of 51 vehicles  were tested during this project.   Of these,
only 50 were subjected to the baseline test program.  The remaining ve-
hicle  together with one vehicle from  the baseline group was used in a
road horsepower test series.  The vehicles were all obtained from the
San Antonio, Texas area from a variety of sources.   Table 2  shows the
numbers of trucks obtained from each source type.  Table 3 is a break-
down of the  50 truck baseline fleet by  body style.  Table  4 is a matrix
presentation showing vehicles tested by  manufacturer, model year,  and
GVW class.  Figures 3 to 6 are photographs of some of the baseline fleet.
For a description of each individual truck, see Table 7.

D.     Fuel

       The fuel used for all tests met the requirements of the Federal
Regulations.  The fuel analysis for the fuel used during this project is
given in Table 5.

       Each truck obtained for testing was weighed at a certified public
scale prior to being brought into the laboratory.  This weight,  less the
weight of any owner added accessories,  was used as the unload or curb
weight.  Each truck was thoroughly inspected upon its arrival at the lab-
oratory.  The exhaust system was checked for leaks and any leaks found
were fixed.  Engine performance,  including timing,  idle speed, and dwell
were checked and recorded.  The engine was checked "by ear and eye" for
proper engine operation.   Any truck with an obvious engine mechanical or
electric  defect was rejected from the  test program.  All pertinent facts
about the engine and drive train were'  recorded on the data sheet.  The
preparations as specified in the Federal Regulations were then begun.

       2.  Baseline Evaporative Emission Tests

       The 1975  light duty evaporative emission test procedure (CFR
Title 40,  Chapter!,  Section 85. 075-11, -12, -13) was strictly adhered
to for this phase  of the  baseline testing, except that the one hour  pre-
conditioning drive called for in Section 85.075-12 was omitted as agreed
upon with the Project Officer. See Appendix B for the detailed procedure.

       3.  Baseline Exhaust Emission Tests

       The exhaust emission tests used the 1975 light duty test procedure
(CFR, Title 40, Chapter 1, Section 85.075-14,  -19, -24) as  specified in
the Federal Regulations.  The one exception to this procedure was that
the inertia weight and road load power table in Section 85. 075-15 was  not
used.  In its place the inertia weight and road load power shown in Table
6 of this report were used.  See Appendix B for the detailed procedure.

       All trucks of model year 1971  or earlier were tested  twice in an as-
received condition.  Trucks of model  years 1972 and 1973 were also tested
twice as-received and if not within factory specification, set to specification
and retested twice more.

       4.  Road Horsepower Determination Tests

       On two vehicles, the road  load power was  determined by actual
road tests at several vehicle weights.  The vehicles were first road tested
empty.  The vehicle weight was then increased in several increments  by
loading it with  sand bags and/or barrels of water.   The  road load power
was  determined for each vehicle weight  using a procedure similar to that
in the Federal Regulations (CFR,  Title 40, Chapter 1,  Section  85.075-15
(e)<2)).  See Appendix B for details of  the procedure.  In order to improve
the accuracy of the procedure, no attempt was made to duplicate the average
road vacuum on the dynamometer to determine  road load power.  Rather,
the road load power was determined at half inch vacuum intei /als over the
vacuum range desired.  Road load as  a function of vehicle weight was  then
determined by cross-plotting the vehicle weight versus vacuum and vacuum
versus road load curves.

Note: Vehicle Test Weight is calculated as follows:


       1)   Gross Vehicle Weight - unloaded weight = payload

                                 I

       2)     If payload is	          Test Load is

              0-2000 Ibs                    500 Ibs
           2001-4000 Ibs                   1000 Ibs
           greater than 4000 Ibs            1500 Ibs

       3)   Vehicle Test Weight = Unloaded Weight + Test Load

                          IV.  TEST RESULTS
A.      Difficulties Encountered in Baseline Tests

        In general, none of the  50 trucks tested had any difficulty completing
the light duty driving cycle.  All vehicles were able to follow the LA-4 driving
cycle within the limits  specified in the current light duty procedure.   While
some vehicles were unable to follow the first high  speed acceleration, this
problem is  recognized in the current light duty procedure which calls lor a
WOT acceleration until the drivers aid line is  intersected in the event that
a vehicle cannot follow the acceleration  schedule.  This was the technique
used during this project whenever a  vehicle could not maintain the acceleration
schedule.  The canisters used  in the evaporative emission testing did require
a great deal of care and technique .to achieve good  results.  As received from
the manufacturer, with about a month  of shelve time at SwRI,  all canisters
contained more moisture than was present in the laboratory during the test.
This would  result in negative evaporative emissions.   A technique was de-
veloped to obtain  completely dry canisters.  The canisters were first dried
in a laboratory oven for at least one half hour  then stored in a desicant cham-
ber  equipped with a fan to constantly circulate the  air within the chamber.
It was also discovered  that under certain humidity conditions when testing
vehicles with large  engines  and high inertia weight, that the 310 SCFM
blower  capacity setting on the CVS was insufficient to prevent moisture
formation in the bags.  This was easily remedied by increasing the blower
capacity to 360 SCFM.  No other equipment or instrumentation problems
were encountered.

       The  other  difficulties concerned vehicles tested at high inertia weights
(9, 000 Ibs and above).  As  mentioned earlier,  it appeared that the horse-
powers listed in Table  6 were excessive for these vehicles.  This was dis-
covered on truck No. 216,  a 1969 Winnebago with a gross weight  of 12, 000 Ibs
and an inertia  weight 11, 200 Ibs.  This vehicle could not develop the  road
load power listed  in the table at 50 mph.

       One  other  oddity should be pointed out.  On some trucks there was
in  effect,  more than one GVW listed on the name plate.  A rating called
"GVWR" was  stated and then a  figure called "Maximum Capacity" which
was  higher than the GVWR  was stated.  The actual warranted gross ve-
hicle weight could be anywhere between the two figures,  depending on the
optional equipment on the vehicle and the tire size.  For example, truck
No.  223 had GVWR of 7, 000 Ibs and a maximum capacity of 14, 000 Ibs.
With the options it had  installed, it was actually warranted to 9, 000 Ibs.

B.      Baseline Emission Test Results

       Table 7 presents the average exhaust and evaporative emission test
results  of the two  as-received tests for each of the 50  trucks tested.   Table

8 is a statistical summary of the average as-received test results showing
average value, maximum value, minimum value,, and standard deviation
for all emissions from each phase of the test as well as the overall test
results in grams per mile.  The same quantities are shown for the evap-
orative test results.

        A summary of the 1972  and 1973 vehicle test results  from tests
with the vehicle engine within factory specifications is  shown in Table 9
for the  22 trucks of model year 1972 or 1973 tested under this project.
Twenty-three percent (5 trucks) of the 22 trucks,  1972 and 1973  model .
year, were received out-of-specification and required  returning and
retesting after the two as-received tests.  Table 10 is  the statistical
summary of the in-specification test results of the 1972 and  1973 trucks
tested.   Appendix A contains the individual test results for each truck.
It should be noted that the mass values for NC>  in all tables  in this  report
                                            jv
and in Appendix A have been corrected for humidity as  specified in  the 1975
light duty procedure.

C.      Road Load Power Test Results

        The results of the road  and chassis  dynamometer tests of the two
trucks (No. 246 and 250) tested at  various inertia and road load horsepower
settings are shown in Table  11.  The relationship between vehicle weight
and road load power is shown in Table 12.  This  relationship was obtained
by cross-plotting the road test and dynamometer test results shown in
Table 11.  For convenience,  this relationship between vehicle weight and
road load power is shown in graphical form in Figure 7 for both trucks tested.
The exhaust emissions at several different inertia weights settings  and cor-
responding road horsepower values are shown in Table 13 for both trucks.

                             CONCLUSIONS
       With the successful completion of testing on 50 trucks with gross
vehicle weights  between 6, 000 to 16, 000 Ibs, the objectives of the  project
have been met.  The truck fleet assembled is varied enough for the test
results to contribute to a proper baseline.   Each truck successfully ran
the light  duty driving cycle.  However,  it  appears that some change may
be required in the test road load power settings at inertia weight settings
above 8, 500 Ibs.

 PART 85—CONTROL  OF AIR  POLLU-
   TION FROM NEW MOTOR VEHICLES
   AND  NEW  MOTOR  VEHICLE  EN-
   GINES
   To facilitate the use  of  the motor ve-
 hicle regulations, and to eliminate con-
 fusion over the  applicability of certain
 provisions  to certain model years,  all
 regulations  applicable to new motor ve-
 hicles and new motor vehicle engines are
 herein republished in a new format.
   Each  subpart contains all the regula-
 tions  applicable  to  a  certain  type of
 motor vehicle  or motor vehicle engine,
 e.g., gasoline-fueled heavy duty  engines.
 Within  each subpart, general provisions
 are  listed first,  followed  by  regulations
 applicable to each successive model year.
 This recornpilation begins with the 1973
 model year, since the certification proc-
 ess  for  the 1972 model year is largely
 completed. Regulations applicable to the
 1972 model year appear at 45 CPR Part
 1201 (Supp. 1971), as amended at 36 P.R.
 5342 (March  20, 1971) and at  36  F.R.
 16905 (August 26, 1971).
   The   orily  substantive  change  con-
 tained in  these regulations makes the
 definition of  "model year", which the
 July 2, 1971, edition of the FEDERAL REG-
 ISTER (36 F.R. 12652)  made applicable to
 the 1975 model  year, applicable to the
 1973 and  1974 model years as well. This
 change  was prescribed  by  section 202 of
 the Clean Air Amendments of 1970 (Pub-
 lic Law 91-604), but was inadvertently
 omitted in prior publications.

   Dated: November 9,1972.

 this subpart. If such statements cannot
 be  made with  respect to any  vehicle
 tested, the vehicle shall be identified, and
 all  pertinent test data relating  thereto
 shall be supplied.

 § 85.075-5   Test vehicles.
   (a)  (1) The  vehicles covered  by  the
 application for  certification  will be di-
 vided into groupings of vehicles whose
 engines  are expected to  have  similar
emission  characteristics. Each group of
 engines with similar emission character-
 istics shall be defined  as a separate  en-
gine family.
  (2) To be classed in the same engine
 family, engines must be identical in all
the following respects:
  (i) The cylinder bore center-to-center
dimensions.
  (ii) The dimension from the centerline
of  the crankshaft to  the centerline of
the camshaft.
  (Hi)  The dimension from the  center-
line of the crankshaft to  the top of the
cylinder block head face.
  (iv)  The  cylinder block configuration
 (air cooled or water cooled; L-6, 90° V-8,
etc.).
  (v) The location of intake and exhaust
valves  and the valve sizes  (within a  %-
inch range on the valve head diameter).
  (vi)  The method of air aspiration.
  (vii) The combustion cycle.
  (3) Engines  identical  in all  the  re-
spects listed in subparagraph (2)  of this
paragraph may be further divided into
different engine families if the Admin-
istrator determines  that  they may be
expected to have different emission char-
acteristics. This  determination  will be
based upon a consideration of the fol-
lowing features of each engine:
  (i) The bore and stroke.
  (il) The  surface-to-volume  ratio of
the nominally  dimensioned cylinder at
the top dead center position.
  (iii)  The intake manifold  induction
port size and configuration.
  (iv)  The  exhaust manifold port size
and configuration.
  (v) The intake  and  exhaust valve
sizes.
  (vi)  The fuel system.
  (vii) The camshaft  timing  and igni-
tion timing characteristics.
  (4) Where engines are of a type which
cannot be divided into engine families
based upon  the criteria listed In sub-
paragraphs  (2)  and  (3)  of  this para-
graph, the Administrator  will establish
families for those engines based upon the
features most related  to their emission
characteristics.
  (b) Emission data vehicles:
  (11 Vehicles will  be  chosen  to  be
operated  and tested for emission data
based upon the engine-family groupings.
 Within each engine family, the require-
 ments of this paragraph must be met.
   (2)  Vehicles  of each engine  family
 will be divided into engine displacement-
 exhaust  emission  control  system-
 evaporative emission control system com-
 binations. A projected sales volume will
. be established for each combination for
 the 1975 model year. One vehicle of each
 combination will  be selected in order of
 decreasing projected sales volume until
 70 percent of the projected sales of a
 manufacturer's total  production  of  ve-
 hicles of  that engine family  is  repre-
 sented, or until a maximum of four  ve-
 hicles is selected.  If any single combina-
 tion represents over 70 percent, then two
 vehicles of that combination will be  se-
 lected. The vehicle selected for each com-
 bination will be specified by the Adminis-
 trator as to transmission type, fuel sys-
 tem, and inertia weight class.
   (3)  The Administrator may select a
 maximum  of  four additional vehicles
 within  each engine family  based upon
 features indicating that they may have
 the highest emission  levels of the  ve-
 hicles in that engine family. In selecting
 these  vehicles,  the Administrator  will
 consider such features  as the emission
 control system combination,  induction
 system characteristics,  ignition  system
 characteristics, fuel system, rated horse-
 power, rated torque, compression ratio.
 inertia weight  class,  transmission op-
 tions, and axle ratios.
   (4) If the vehicles selected in accord-
 ance with subparagraphs (2> and (3) of
 this paragraph do  not represent each
 engine-system combination,  then  one
 vehicle of  each engine-system  combina-
 tion not represented will be selected by
 the Administrator. The vehicle selected
 shall be of the engine  displacement with
 the largest projected sales volume of ve-
 hicles with the control system  combina-
 tion in the engine  family and  will be
 designated  by the Administrator as to
 transmission type, fuel  system, and in-
 ertia weight class.
   (c) Durability data  vehicles:
   (1) A durability data vehicle  will be
 selected by the Administrator  to  repre-
 sent each  engine-system combination.
 The vehicle selected shall be of the en-
 gine displacement with  the largest pro-
 jected sales volume of  vehicles with that
 control-system combination In that en-
 gine family and will be designated by the
 Administrator as  to transmission type.
 fuel system, and inertia weight class.
   (2) If an  exhaust  emission  control
 system-fuel evaporative emission control
 system combination is used in only one
 engine family, an additional vehicle us-
 ing that combination in that family will
 be  selected so that the durability data
 fleet shall  contain at  least two vehicles
 with each  combination. The additional
 vehicle will be selected in the same man-
 ner as  vehicles  selected  under  sub-
 paragraph (1) of  this paragraph.
   (3) A manufacturer may elect to op-
 erate and  test additional vehicles  to
 represent any engine-system combina-
 tion. The additional vehicles must be of
 the same engine displacement, transmis-
 sion type, fuel system, and inertia weight

 this  subpart for the 1975 model year Is
less  than 2,000  vehicles may request  a
reduction in the number of test vehicles
determined in accordance with the fore-
going provisions of this section. The Ad-
ministrator  may "-agree  to  such lesser
number  as he determines would meet
the objectives  of this procedure.
  (f) In lieu of testing an emission data
or durability data  vehicle selected under
paragraph (b) or (c) of this section, and
submitting data therefor, a manufacturer
may, with the prior written  approval of
the  Administrator, submit  data on  a
similar  vehicle  for  which certification

Item shall be included in the  curb weight
computation for the entire engine fam-
ily. Where it is expected that 33 percent
or less of the vehicles in an engine family
will  be  equipped  with  an Item of op-
tional equipment, no weight for that Item
 will  be added In computing curb weight.
Optional equipment  weighing less than
3  pounds  per   item  need   not  be
considered.

§ 85.075-7  Mileage  accumulation end
    emission measurement*.
  The procedure for mileage accumula-
tion will be the Durability Driving Sched-
ule as specified in Appendix IV to this
part. A  modified procedure may also be
used  if  approved in  advance  by  the
Administrator.
  (a) Emission  data  vehicles:  Each
emission data vehicle  shall  be  driven
4,000 miles with all emission control sys-
tems installed and operating. Emission
tests shall be conducted at zero miles and
4,000 miles.
  (b) Durability  data  vehicles:  Each
durability data vehicle shall be driven,
with  all emission control  systems  in-
stalled and operating, for 50,000 miles or
such lesser distance as the Administrator
may agree to as meeting the objectives
of this  procedure. Emission measure-
ments from a  cold start shall be made at
zero   miles   and  at  each 4,000-mile
interval.
  (c)  All tests required by this subpart
to be  conducted  after 4,000  miles  of
driving or at any multiple of 4,000 miles
may be  conducted at  any  accumulated
mileage within 250 miles of 4,000 miles or
the appropriate multiple of 4,000  miles,
respectively.
  (d) The results of  each emission test
shall  be supplied to  the  Administrator
immediately   after  the  test. Where  a
manufacturer conducts multiple tests at
any test point or any tests  between test
points,  data  on  these  tests  (including
voided tests)  shall be provided immedi-
ately  to  the Administrator. In addition,
all test  data shall be  compiled and pro-
vided to the Administrator in accordance
with 8 85.075-4.
  (e)  Whenever the manufacturer pro-
poses to operate and test a  vehicle which
may be  used  for emission or durability
data, he shall provide the zero mile test
data to the Administrator and make the
vehicle available for such  testing  under
§ 85.075-20 as the Administrator may re-
quire before  beginning to  accumulate
mileage on the vehicle. Failure to comply
with this requirement will  invalidate  all
test data submitted for  this vehicle.
  (f)  Once a manufacturer begins to
operate  an emission data or durability
data vehicle,  as indicated by compliance
with paragraph (e)  of this section,  he
shall continue to run the vehicle to 4,000
miles or 50,000 miles, respectively, and
the data from the vehicle will be used in
the calculations under  9 85.075-28. Dis-
continuation of a vehicle shall be allowed
only with  the written consent of  the
Administrator.
  (g)(l) The Administrator  may elect
to operate and test any test vehicle dur-
ing all or any part of  the mileage  ac-
cumulation  and  testing  procedure.  In
such cases, the manufacturer shall pro-
vide the  vehlcle(s) to the Administrator
with all  Information  necessary  to con-
duct this testing.

      RULES AND REGULATIONS
  (2) The test procedures in 85 85.075-10
through 85.075-27 will be followed by the
Administrator. The Administrator  will
test the vehicles at each test point. Main*
tenance may be performed by the manu-
facturer  under such conditions as the
Administrator may prescribe.
  (3) The data developed by the Admin-
istrator for  the engine-system combina-
tion  shall be combined with any appli-
cable data supplied by the manufacturer
on other vehicles of that combination to
determine the applicable deterioration
factors for the combination. In the case
of a significant  discrepancy between
data  developed by the  Administrator
and that submitted by the manufacturer,
the Administrator's data shall  be  used
In the  determination  of deterioration
factors.

§ 85.075—8  Special test procedures.
  The Administrator may, on the basis of
a written application therefor by a man-
ufacturer,  prescribe  test  procedures.
other than  those set forth in this sub-
part, for any motor vehicle which he de-
termines is not susceptible to satisfactory
testing by the procedures set forth herein.
§ 85.075-9  Test procedures.
  The procedures  described in this and
subsequent sections will be the test pro-
gram to  determine the  conformity of
vehicles  with  the  standards set  forth
in § 85.075-1.
   (a) The  test consists of  prescribed
sequences of fueling, parking, and oper-
ating conditions. The exhaust gases gen-
erated  during  vehicle   operation  are
diluted  with air  and  sampled continu-
ously for subsequent analysis of specific
components  by  prescribed  analytical
techniques.  The fuel  evaporative  emis-
sions are collected for subsequent weigh-
ing  during 'both   vehicle parking  and
operating events. The  test applies to ve-
hicles equipped with catalytic or direct-
flame  afterburners,  induction system
modifications, or other systems or to un-
controlled vehicles and engines.
  (b> The exhaust  emission test is de-
signed to determine hydrocarbon, carbon
monoxide, and oxides of nitrogen  mass
emissions while simulating an average
trip in an urban area of 7.5 miles. The
test consists of engine startups and ve-
hicle  operation on  a chassis dynamom-
eter through a specified driving schedule,
as described in Appendix I to this part.
A proportional part of  the  diluted ex-
haust emissions is collected continuously,
for subsequent analysis, using a constant
volume (variable dilution) sampler.
   (c) The fuel evaporative emission test
is designed  to determine  fuel hydro-
carbon evaporative  emissions to the at-
mosphere as  a consequence of  urban
driving,  and  diurnal  temperature  fluc-
tuations during parking.  It is associated
with a series of events representative of
a motor  vehicle's operation, which result
in fuel vapor losses directly from the fuel
tank  and carburetor. Activated carbon
traps  are employed  in  collecting the
vaporized fuel. The  test procedure  is
specifically   aimed  at  collecting  and
weighing:
  (1) Diurnal breathing losses from the
fuel tank and other parts of the fuel sys-
tem when the fuel tank is subjected to a
temperature  Increase  representative of
the diurnal range;
  (2) Running losses from the fuel tank
and  carburetor  resulting from a  simu-
lated trip  on a  chassis dynamometer;
and
  (3) Hot soak losses from the fuel tank
and  carburetor  which  result when  the
vehicle is parked and the hot engine  is
turned off.
  (d) All emission control systems in-
stalled on or incorporated in a new  motor
vehicle shall be  functioning  during all
test procedures in this subpart.

§85.075-10   Gasoline specifications.
  (a) Fuel having the following specifi-
cations or substantially equivalent  speci-
fications approved by the Administrator,
shall be used in exhaust and  evaporative
emission testing. The lead content  and
octane rating of the fuel shall be  in the
range recommended  by the  vehicle or
engine manufacturer.

   (b)  Fuels   representative  of  com-
merial  fuels  which  will  generally  be
available through retail outlets shall be
used in mileage accumulation. The lead
content and octane rating of  the  fuel
used shall be in the range recommended
by the vehicle or engine manufacturer.
The Reid vapor pressure of the fuel used
shall be characteristic of the motor fuel
during the season during which the mile-
age accumulation takes place.
   (c)  The  specification  range  of  the
fuels to be used under paragraph (b) of
this section shall be reported in accord-
ance with § 85.075-2(b) (3).

§85.075—11   Vehicle and engine prepa-
     ration (fuel evaporative emissions).

   (a)  (1)  Apply  approximate leak-proof
fittings to all fuel system external vents
to permit  collection of effluent  vapors
from these  vents during the course of
the prescribed tests. Since the prescribed
test requires the temporary plugging of
the inlet pipe to the air cleaner, it will
be necessary to install a probe for col-
lecting the normal effluents  from  this
source. Where antisurge/vent filler caps
are employed on the fuel tank, plug off
the normal vent if it does not  conveni-
ently  lend  itself to  the collection of
vapors which emanate from it, and in-
troduce a separate vent, with appropriate
fitting, on the cap. Where the fuel tank
vent line terminus Is inaccessible, sever
the line at a convenient point near the
fuel tank and install the collection sys-
tem In a closed circuit assembly with the
severed ends. All fittings shall terminate
in s/i«-inch  ID tube  sections for ready
connection to the collection systems and
shall  be designed  for  minimum  dead
space.
  (2) The design and installation of the
necessary fittings shall  not  disturb the
normal function of the fuel system com-
ponents or the normal pressure relation-
ships in the  system.
  (b) (1) Inspect the fuel system care-
fully  to Insure the absence of any leaks
to  the  atmosphere  of  either  liquid or
vapor which might  affect the accuracy
of the test  or the performance of the
control system. Corrective action, if any,
shall  be reported  with  the  test results
under 8 85.075-4.
  (2) Care  should  be exercised, in the
application of any pressure tests, neither
to purge nor load the evaporative emis-
sion control system.
  (c) Prepare fuel  tank  for  recording
the temperature of the  prescribed test
fuel at its approximate midvolume.
  (d) Provide additional fittings  and
adapters, as required,  to accommodate
a fuel drain at the lowest point possible
in the tank as installed  on  the  vehicle.
§ 85.075-12   Vehicle    preconditioning
     (fuel evaporative emissions).
  Vehicles to be tested for  compliance
with  the  fuel evaporative emissions
standard of this subpart shall be pre-
conditioned  as follows:
  (a) The test vehicle shall  be operated
under the conditions prescribed for mile-
age accumulation, § 85.075-7, for 1 hour
Immediately prior to the operations pre-
scribed below.
  (b) The fuel tank shall be drained and
specified  test  fuel   (§ 85.075-10 (a) )
added. The  evaporative emission control
system or device shall not be abnormally
purged  or loaded as a result of draining
or fueling the tank.
  (c) The test vehicle  shall be placed
on  the dynamometer and operated over
a simulated trip, according to the appli-
cable requirements  and procedures of
9585.075-14  through 85.075-19 except
that  the engine need not be cold when
starting the run on the dynamometer
and only a  single trip of 7.5 miles shall
be run. During the run the ambient tem-
perature shall be between  611"  F.  and
86° F.
  (d> The engine and cooling fan shall
be stopped upon completion of the dyna-
mometer operation and the vehicle per-
mitted  to  soak  either on  or  off the
dynamometer stand at an ambient tem-
perature between 76° F. and 86° F. for a
period of not less than 1 hour prior to
the soak period prescribed  in I 85.075-
          § 85.075—13  Evaporative emission  col-
              lection procedure.
            The  standard test procedure  consists
          of three parts  described below which
          shall be performed in sequence and with-
          out any Interruption in  the test condi-
          tions prescribed.

   (a) Diurnal breathing loss  test.  (1)
 The test vehicle  shall  be allowed to
 "soak" In an  area where the ambient
 temperature Is maintained between 60°
 F. and 88° F. for a period of not lesa than
 10 hours. (The vehicle preparation re-
 quirements of 8 85.075-11 may be per-
 formed during this period.) It shall then
 be transferred to a soak area where the
 ambient  temperature Is maintained be-
 tween 76' F. and 88° F. Upon admittance
 to the 78" F.-86" F. soak area, the pre-
 scribed fuel tank thermocouple shall be
 connected to the recorder and the fuel
 and ambient  temperatures recorded at
 a chart speed of approximately 12 Inches
 per hour  (or equivalent record).
   (2) The fuel tank of the prepared test
 vehicle,   preconditioned  according  to
 8 85.075-12, shall   be drained  and  re-
 charged  with  the  specified test fuel,
 §85.075-10(a), to  the prescribed  "tank
 fuel volume,"  defined in § 85.002. The
 temperature of the fuel following  the
 charge to the tank shall be 60° F.±2° F.
 Care should be exercised against abnor-
 mal loading of the evaporative emission
 control system or device  as  a result of
 fueling the tank.
   (3) Immediately  following the  fuel
 charge to the tank, the exhaust pipe(s)
 and inlet  pipe to the air cleaner shall be
 plugged and the prescribed vapor collec-
 tion systems installed on all fuel system
 external  vents. Multiple  vents may be
 connected to a single collection trap pro-
 vided that, where  there  is  more than
 one  external vent on a fuel system dis-
 tinguishing between carburetor and tank
 vapors, separate collection systems shall
 be employed to trap the vapors from ttie
 separate sources. Every precaution shall
 be taken  to minimize the  lengths of  the
 collection tubing employed and to avoid
 sharp bends across the entire system.
   (4) Artificial means shall be employed
 to heat the fuel  in the tank to  84° F.
 ±2° F. The  prescribed temperature of
 the fuel shall be achieved over a period
 of 60 minutes ±10 minutes using a con-
 stant rate of heat  input.  After a mini-
 mum of 1 hour, following  admittance to
 the 76° F.-B6°  F. soak area,  the vehicle
 shall be moved onto the  dynamometer
 stand for the subsequent part of the test.
 The  fuel  tank thermocouple  may  be
 temporarily disconnected to permit mov-
 ing the test vehicle. Plugs shall be  re-
 moved from  the  exhaust pipe(s) and
 Inlet pipe  to the air cleaner.
  (to) Running loss test. (1) The vehicle
 shall be placed on the dynamometer and
 the fuel tank thermocouple reconnected.
 The  fuel  temperature and the  ambient
 air temperature shall be  recorded at a
 chart speed of  approximately 12 inches
 per hour (or equivalent record).
  (2) Where an external vent Is located
such that  any "running loss" emissions
 would be  inducted Into the engine, the
 vapor loss measurement system shall be
 temporarily disconnected from that vent
and clamped. Vapor losses from this vent
need not be measured during this part
 of the test.
  (3) The vehicle  shall be operated  on
 the dynamometer  according  to the re-
 quirements and procedures of 89 86.075-
 14 through 85.076-24. The engine and
 fan shall be turned off upon completion
 of the dynamometer run and the exhaust
 and  air  cleaner  Inlet pipes  shall  be
 replugged.
   (4) Vapor losses need not be measured
 during the 10-mlnute soak or SOS-second
 "hot" start test. Any vapor loss collection
 system used during the cold start shall
 be   temporarily   disconnected   and
 clamped. At the end of the hot start test,
 the vapor collection systems shall be re-
 connected for the following phase.
   (c) Hot soak test. Upon completion of
 the dynamometer  run, the test vehicle
 shall  be  permitted to  soak with hood
 down for a period of 1 hour at an am-
 bient temperature between 78° F. and
 86° F. This operation completes the test.
 The traps are disconnected  and weighed
 according to 8 85.075-21.

 § 85.075-14 Dynamometer    driving
     schedule.
   (a) The dynamometer  driving sched-
 ule  to be followed consists of a non-
 repetitive  series of  Idle, acceleration,
 cruise, and deceleration modes of vari-
 ous time  sequences and rates. The driv-
 ing schedule Is denned  by a smooth
 transition through the speed  vs. time
 relationships listed in Appendix I. The
 time sequence  begins upon  starting the
 vehicle according  to the startup proce-
 dure described In  «. 85.075-19.
   (b)  A speed  tolerance  of ±2 m.pJi.
 and a time tolerance of ±1 second (or an
 algebraic combination of the two)  from
 either the speed-time relationship pre-
 scribed in Appendix I or  as printed on
 a driver's aid chart approved by the Ad-
 ministrator are acceptable. Speed toler-
 ances greater than 2 m.p.h.  (such as oc-
 cur when shifting manual transmission
 vehicles)  are acceptable  provided they
 occur for less than 2 seconds on any one
 occasion.  Speeds lower  than those pre-
 scribed may be acceptable provided that
 the  vehicle  is  operated  at maximum
 available power during such  occurrences.
 Further,  speed  deviations  from those
 prescribed due to stalling are acceptable
 provided the provisions of §  85.075-19(f)
 are adhered to.

 § 85.075—15  Dynamometer procedure.
  (a)  The  dynamometer  run  consists
 of two tests, a "cold" start  test after a
 minimum 12-hour  soak according to the
 provisions of 8§85.075-12  and 85.075-13
 and a "hot" start test with a 10-mlnute
 soak  between  the two  tests.  Engine
 startup,  operation over  the   driving
 schedule,  and engine shutdown make a
 complete cold start test. Engine startup
 and operation over the first  505 seconds
 of  the driving  schedule  complete  the
 hot start test. The exhaust emissions
 are diluted with air to  a  constant vol-
 ume and a portion is sampled continu-
ously during each  test. The composite
 samples collected in bags are analyzed
 for  hydrocarbons, carbon   monoxide.
carbon dioxide, and oxides of nitrogen.
A parallel sample  of the dilution air  Is
similarly analyzed for  hydrocarbon, car-
bon monoxide, and oxides  of nitrogen.
  (b) During  dynamometer operation,
a fixed speed cooling fan  shall  be posi-
tioned so as to  direct  cooling air to the
 vehicle In an appropriate manner with
 the engine compartment cover open. The
 fan capacity shall normally not exceed
 5,300 c_f.m. If,  however,  the manufac-
 turer can show  that during fleld opera-
 tion the vehicle  receives additional cool-
 Ing, the fan capacity may be Increased or
 additional fans  used if approved in ad-
 vance by the Administrator. In the case
 of vehicles with front  engine compart-
 ments, the fan(s) shall be squarely po-
 sitioned between 8 and 12 Inches In front
 of the cooling air  inlets  (grill). In the
 case of vehicles with rear engine com-
 partments  (or  if special designs make
 the  above impractical),   the  cooling
 fan(s)  shall be placed in a position to
 provide sufficient air to maintain engine
 cooling.
   (c) The vehicle  shall be nearly level
 when tested in  order to prevent abnor-
 mal fuel distribution.
   (d)  Flywheels,   electrical  or  other
 means of simulating Inertia as shown In
 the following  table shall be used. If the
 equivalent inertia specified Is not avail-
 able on the dynamometer being used, the
 next higher equivalent Inertia  (not  to
 exceed 250 IDS.) available shall  be used.

   (1) The power absorption unit shall
be adjusted to reproduce road load power
at 50 m.p.h. true speed. The  Indicated
road load power setting shall  take into
account the dynamometer  friction. The
relationship  between  road load   (ab-
sorbed) power  and indicated road load
power for  a particular  dynamometer
shall be determined  by the procedure
outlined in Appendix n or other suit-
able means.
   (2) The road load power listed in the
table above shall be used or the vehicle
manufacturer may  determine the road
load power by  the  following procedure
and request Its use:
   (i)  Measuring the absolute  manifold
pressure of a representative vehicle, of
the same equivalent inertia weight class,
when operated on  a level road under
balanced wind conditions at a true  speed
of 50 m.p.h., and
   (11) Noting  the  dynamometer  Indi-
cated road load horsepower setting re-
quired to reproduce that manifold pres-
sure when the same vehicle Is operated
on the dynamometer at a true spcjd of
50 m.p.h. The tests on the road  and on
the dynamometer shall  be performed
with the same vehicle ambient absolute
pressure (usually barometric), i.e. within
±5 mm. Hg.

                                              RULES  AND  iE6UU?IONS
  (ill) The road load power shall be de-
termined according to the procedure out-
lined  In Appendix n and adjusted ac-
cording to the following If applicable.
  (3)  Where it Is  expected that more
than  33 percent  of  the vehicles In an
engine family will be equipped with air
conditioning, the  road load power listed
above or as determined  in paragraph  2
of this subsection shall be increased by
10 percent 'for testing  all test  vehicles
representing such engine family.
  (f)  The  vehicle   speed   (m.p.h.) as
measured  from the dynamometer  rolls
shall be used for  all conditions.  A speed
vs. time recording, as evidence of dyna-
mometer test validity, shall be supplied
on request of the Administrator.
  (g) Practice runs over the prescribed
driving schedule may be performed to
find  the  minimum throttle  action to
maintain the proper speed-time relation-
ship.
  NOTE: When using two-roll dynamometers
a truer speed-time  trace may be obtained by
minimizing the rocking of the vehicle In
the rolls. The rocking of the vehicle changes'
the tire rolling radius on each roll. The rock-
Ing may be minimized by restraining the
vehicle horizontally (or nearly so)  by  using
a cable and winch.
  (h)  The drive  wheel  tires may be In-
flated up to 45 p.s.i.g. hi order to prevent
tire damage. The drive wheel tire pres-
sure  shall  be  reported with  the  test
results.
  (i)  If the dynamometer has not been
operated during  the 2-hour period Im-
mediately preceding the test it  shall be
warmed up for 15 minutes by operating
it at  30 m.p.h. using a  nontest vehicle.
§ 85.075—16  Three-speed manual trans-
    missions.
  (a) All test conditions except as noted
shall  be run in highest gear.
  (b) Cars equipped with free wheeling
or overdrive units  shall be tested  with
this  unit  (free wheeling or overdrive)
locked out of operation.
  (c) Idle shall  be  run with transmis-
sion in gear and  with clutch disengaged
(except first idle: see § 85.075-19).
  (d) The vehicle shall be driven  with
minimum throttle movement to main-
tain the desired speed.
  (e)  Acceleration modes shall be driven
smoothly with the shift speeds as recom-
mended by the  manufacturer. If  the
manufacturer does not recommend  shift
speeds, the vehicle shall be shifted from
first  to second gear at 15 m.p.h.  and
from  second  to third gear at 25 m.p.h.
The operator shall release the accelerator
pedal  during the shift, and accomplish
the shift with minimum closed  throttle
time.  If the vehicle cannot accelerate at
the specified rates, the vehicle shall be
accelerated at' WOT until the vehicle
speed  reaches  the  speed  at which it
should be at that time during the test.
  (f)  The  deceleration modes shall be
run with  clutch  engaged  and  without
shifting gears from the previous mode,
using brakes or throttle as necessary to
maintain  the desired speed. For those
modes which  decelerate to  aero,  the
clutch shall be depressed when the speed
drops  below  15  m.p.h., when  engine
roughness  is evident, or when engine
stalling Is Imminent.
  (g) Downshifting is allowed at the be-
ginning of or during a  power mode if
recommended by the manufacturer or if
the engine obviously Is lugging.

§ 85.075-17  Four-speed and five-speed
     manual transmissions.
  (a) Use  the same procedure as for
three-speed  manual  transmissions for
shifting from first to second gear and
from second to third gear. If the manu-
facturer does   not  recommend   shift
speeds,  the vehicle shall be shifted from
third to fourth  gear  at 40 m.p.h.  Fifth
gear may be used at the manufacturer's
option.
  (b) If transmission ratio in first gear
exceeds 5:1, follow the procedure for
three- or  four-speed  manual transmis-
sion vehicles as if the first gear did not
exist.
§ 85.075—18  Automatic transmissions.
  (a) All  test  conditions shall be run
with the transmission in "Drive" (highest
gear). Automatic  stick-shift  transmis-
sions may be shifted as manual transmis-
sions at the option of the manufacturer.
  (b) Idle  modes shall be run with the
transmission in  "Drive" and  the wheels
braked (except first idle; see §  85.075-10).
  (c) The  vehicle shall  be driven  with
minimum  throttle movement to main-
tain the desired speed.
  (d) Acceleration modes shall be driven
smoothly allowing  the  transmission  to
shift automatically through the normal
sequence of gears. If the vehicle cannot
accelerate at the specified rates, the ve-
hicle shall  be accelerated at WOT until
the vehicle  speed  reaches the speed at
which it should be at that .time during
the driving schedule.
  (e) The  deceleration modes shall be
run in gear using brakes or  throttle as
necessary to maintain the desired speed.
§ 85.075-19  Engine  starting  and  re-
    starting.
  (a) The  engine shall  be started ac-
cording to  the  manufacturer's recom-
mended starting procedures. The initial
20-second-ldle period shall begin  when
the engine starts.
  (b) Choke operation:
  (1) Vehicles equipped with automatic
chokes shall be operated according to the
manufacturer's  operating  or owner's
manual Including  choke  setting  and
"kick-down" from cold fast idle. If choke
"kick-down" time is not specified, it shall
be performed 13 seconds after the en-
gine starts. The transmission shall be
placed in gear 15 seconds after the engine
is started. If necessary,  braking may be
employed to keep the drive wheels from
turning.
  (2) Vehicles  equipped  with manual
chokes  shall be operated according  to
the Instructions which will be included
in the manufacturer's operating or own-
er's manual. If not specified,  the choke
shall be operated to maintain  engine idle
at  1,100±50 r.p.m.  during  the initial
idle  period  and used  where  necessary
during the remainder of the test to  keep
the engine running.
  (c)  The operator may use more choke,
more throttle,  etc., where necessary to
keep the engine running.

                                                                       24271
  to provide  additional Information and
  coordinate the functions of the compo-
  nent systems.
    (b)  Component description  (.exhaust
  gas sampling  system).  The  following
  components will be used In the exhaust
  gas sampling system for testing under
  the regulations in this part. See Figure
  A7S-1. Other types of constant volume
  samplers may be used If shown to yield
  equivalent results.
    (1)  A dilution air filter assembly con-
  sisting of a participate (paper) filter to
  remove solid matter  from the dilution
• .air and thus increase the life of the char-
  coal filter;  a charcoal filter to  reduce
  and stabilize the background hydrocar-
.  bon level; and a second particulate filter
  to remove charcoal particles from the air
  stream. The niters shall be of  sufficient
  capacity and the duct which carries  the
  dilution  air to the point where the  ex-
  haust  gas is  added shall be of sufficient
  size so that the pressure at the mixing
  point is less than 1 Inch of water pres-
  sure below ambient when" the  constant
  volume sampler is operating at its maxi-
  mum flow rate.  .
    (2) A  flexible,  leak-tight connector
  and tube to the vehicle tailpipe. The flexi-
  ble tubing shall be sized and connected in
  such a manner that the' static pressure
  variations in the vehicle tallplpe(s)  re-
  main within ±1 'inch of water  of the
  static pressure  variations measured dur-
  ing a dynamometer driving cycle with no
  connections to the tailpipe Cs).
    (3) A  heating  system  to  preheat the
  heat exchanger to within ±10° F. of Its
  operating temperature before  the test
  begins.
    (4) A heat exchanger capable of limit-
  ing the gas mixture temperature varia-
  tion during the entire test to ±10° F. as
  measured at a  point immediately ahead
  of the  positive displacement pump.
    (5) A  positive  displacement pump to
  pump the dilute  exhaust mixture. The
  pump capacity  (300 to 350 c.f.m. Is suffi-
  cient for testing most vehicles) shall be
  large enough to virtually eliminate water
  condensation In the system. See Appendix
  in for flow calibration techniques.
    (6) Temperature sensor (Tl) with an
  accuracy of ±2° F. to allow continuous
  recording of  the temperature  of the
  dilute exhaust mixture entering the posi-
  tive displacement  pump. (See § 85.075-

 insure,  by visual observation, that con-
 stant flow rates are maintained through-
 out the test.
   (14)  Three-way solenoid valves  (VI,
 V2, V3, and V4) to direct sample streams
 to either  their  respective  bags  or

 the regulations in this part. The analyt-
 ical system provides for the determina-
 tion of hydrocarbon concentrations by
 flame lonlzatlon detector (FID)  analy-
 sis, the determination of carbon mon-
 oxide and carbon dioxide concentrations
 by nondisperslve infrared (NDIR)  analy-
sis and the  determination of oxides of
 nitrogen concentrations  by chemiluml-
 nescence (CL) analysis in dilute exhaust

  (1) The  temperature and pressure of
the mixture of exhaust and dilution air
entering   the   positive   displacement
pump and the pressure increases across
the  pump.  The  temperature  of the
mixture shall be recorded continuously
or digitally at a rate often enough to
determine   temperature  variations,  or
it may be controlled to  ±5°  F. of the
set  point  of the temperature  control
system.  In the  last case only  the  set

§ 85.075x23  Analytical system calibra-
    tion and sample handling.
  (a)  Calibrate the analytical assembly
at least  once every 30 days. TJse  the
same  flow  rate  as   when  analyzing
samples.
  (1)  Adjust analyzers to optimism per-
formance.
  (2)  Zero  the hydrocarbon analyzer
with  zero  grade  air  and  'the  carbon
monoxide, carbon dioxide, and oxides of
nitrogen  analyzers  with  zero  grade
nitrogen.   The   allowable   zero   gas
impurity concentrations should not ex-
ceed  1  p.pjn.  equivalent  carbon  re-
sponse,  1  p.pjn. carbon monoxide,  300
p.p.m. (0.03  mole  percent)  carbon di-
oxide, and 0.1 p.p.m. nitric oxide.
  (3)  Set the CO and CO, analyzer gains
to give the desired  ranges. Select the de-
sired  attenuation scale of the HC ana-
lyzer  and set the  sample capillary flow
rate,  by adjusting the  back pressure
regulator, to  give the desired  range. Se-
lect the desired scale of the NO. analyzer
and adjust the  phototube high  voltage
supply or the amplifier gain to give the
desired  range.
  (4)  Calibrate the HC analyzer with
propane (air diluent) gases having nom-
inal concentrations equal to 50 and 100
percent of full scale. Calibrate the CO
analyzer with carbon  monoxide (nitro-
gen diluent)  gases and the CO, analyzer
with  carbon  dioxide (nitrogen diluent)
gases  having  nominal concentrations
equal to 10, 25, 40. 50, 60. 70. 85. and 100
percent of fuD scale. Calibrate the NO,
analyzer with nitric oxide (nitrogen dilu-
ent)  gases having nominal  concentra-
tions  equal to 50 and 100 percent of full
scale. The actual concentrations should
be known to within ±2 percent of the
true values.
  (5) Compare  values obtained on the
CO and CO, analyzers with previous cali-
bration curves.  Any significant change
reflects some problem in  the  system.
Locate and correct problem, and recali-
brate. Use best judgment in selecting
curves for data reduction.
  (6) Check the NO,  to NO converter
efficiency by the following procedure:
  (1)  Fill a new (not previously used to
collect exhaust gas samples) sample bag
with  air (or  oxygen)  and, NO span gas
in proportions which result in a mix In
the operating range of the analyzer. Pro-
vide enough oxygen SOT substantial con-
version of NO to  NO,.
  (ii) Knead bag and  immediately con-
nect  the bag to the sample inlet  and
alternately measure the NO and NO,
concentration at 1-minute intervals by
alternately passing the sample through
the  converter and  the bypass (close
valves N6  and  N10 to mintmtm pump
down rate of bag). After several minutes
of operation,  the  recording of NO and
NO, will resemble Figure A75-7 if the con-
verter  Is  efficient.  Even  though  the
amount of NO,  increases with time, the
total  NO, (NO+NO.) remains constant.
A decay of NO, with time indicates the
converter is  not essentially 100  percent
efficient and the cause'should be deter-
mined before the  instrument Is used.
  (ill)  The converter efficiency should
be  checked at least  once weekly  and
preferably once dally.

  (7) Check the efficiency of the sample
conditioning system  by  the  following
procedure:
  (i)  Zero and span the CO Instrument
on its most  sensitive scale.
  (11) Recheck zero.
  (ill)  Bubble CO, span  gas through
water and then through the sample con-
ditioning system into the CO Instrument.
If the CO Instrument shows no response
to the wet CO, the  columns are  in good
condition.
  (iv) If the CO instrument responds to
wet CO,, replace columns as necessary to
bring response back  to zero.
  (v) The conditioning system efficiency
should be checked dally.
  (b) HC. CO, CO,, and NO, measure-
ments:  Allow a minimum of 20 minutes
warmup for the HC  analyzer and 2 hours
for the CO, CO,,  and NO.  analyzers.
(Power is normally  left on Infrared and
chemilumlnescence  analyzers; but when
not in use, the chopper motors of the In-
frared analyzers are turned off and  the
phototube high voltage supply  of  the
chemilumlnescence  analyzer is placed in
the standby position.) The following se-
quence  of   operations  should be  per-
formed in •conjunction with each series
of measurements:
  (1) Zero the analyzers. Obtain  a stable
zero on each amplifier  meter and  re-
corder.  Recheck after tests.
  (2) Introduce span gases and set  the
CO and CO, analyzer gains, the HC ana-
lyzer sample capillary flow rate and  the
NO. analyzer high voltage supply or am-
plifier gain to  match  the calibration
curves.  In  order to  avoid corrections,
span and calibrate at the same flow rates
used  to analyze the test samples.  Span
gases should have  concentrations equal
to approximately 80 percent of full scale.
If gain has shifted significantly on  the
CO or  CO,  analyzers, check tuning. If
necessary,  check calibration. Recheck
after test.  Show actual concentrations
on chart.
  (3) Check zeroes; repeat the procedure
in subparagraphs  (1) and (2)  of this
paragraph if required.
  (4)  Check flow  rates and  pressures.

 § 85.075-24  Dynamometer lest runs.
    (a) The vehicle shall  be allowed  to
 stand with the engine turned  off for a
 period of  not less than 12 hours before
 the cold start exhaust emission test, at
 an ambient temperature  as specified in
 §§85.075-12 and 85.075-13. The vehicle
 shall be stored prior to the emission tests
 in such  a manner that precipitation (e.g.
 rain or  dew) does nat occur on the ve-
 hicle. The complete dynamometer test
 consists of a cold start drive of 7.5 miles
 and simulates a  hot start  drive of 7.5
 miles. The vehicle  is allowed to stand on
 the dynamometer  during  the 10-minute
 time period between the cold  and hot
 start tests. The cold start test is divided
 into two periods. The first period, repre-
 senting  the cold start "transient" phase,
 terminates at the end of the deceleration
 which is scheduled to occur at 505 sec-
 onds of  the driving schedule. The second
 period,  representing  the  "stabilized"
 phase, consists of  the remainder of the
 driving  schedule including engine shut-
 down. The hot  start test  similarly  con-
 sists  of  two  periods. The first period,
 representing  the  hot start "transient"
 phase, terminates  at the  same point In
 the driving schedule as the first phase
 of  the cold start test. The .second period
 of  the hot start test, "stabilized" phase,
 is assumed to be identical to the second
 period of the cold  start test. Therefore,
 the hot  start test  terminates  after the
 first period (505 seconds)  is run. During
 the tests the ambient temperature shall
 be between 68° F. and 86°  F.
   (b)  The following steps  shall  be taken
 for each test:
  (1) Place drive wheels  of vehicle on
dynamometer without starting engine.
  (2) Open the vehicle engine compart-
ment cover and start the cooling fan.
  (3) With the sample solenoid valves in
the "dump" position connect evacuated
sample collection bags to the two dilute
exhaust  sample connectors and to the
two dilution air sample line connectors.
  (4) Start  the  positive  displacement
pump  (if not already on),  the sample
pumps, and  the  temperature  recorder.
 (The heat exchanger of the constant vol-
ume sampler should be preheated to Its
operating  temperature before   the  test
begins.)
  (5)  Adjust  the  sample  flow  rates to
the desired flow  rate (minimum ol 10
c.f.h.)  and  set the  revolution  counters
to zero.
  (6)  Attach the flexible exhaust tube to
the vehicle tailpipe(s).
  (7)  Simultaneously start the revolu-
tion counter for the positive displace-
ment pump, position the sample  solenoid
valves to direct the sample flow  into the
 "transient" exhaust sample bag and the
 "transient" dilution air sample bag, and
 start cranking the engine.
    (8) Fifteen seconds after the engine
 starts, place the  transmission in  gear.
    (9) Twenty seconds after the engine
 starts, begin the initial vehicle accelera-
 tion of the driving schedule.
    (10) Operate the  vehicle according to
 the   dynamometer   driving  schedule
 (§85.075-14).
    (11) At  the end  of the deceleration
 which is scheduled to occur at 505 sec-
 onds, simultaneously switch the  sample
 flows from  the "transient" bags to the
 "stabilized" bags,  switch off  revolution
 counter No. 1 and start counter No. 2.
 As soon as possible and in no case longer
 than 20  minutes  after  the end of this
 portion of the test disconnect the "tran-
 sient" exhaust and  dilution air sample
 bags, transfer them to the  analytical
 system and  process the samples accord-
 ing to § 85.075-23.
    (12) Immediately after the end of the
 sample period turn  off  the cooling fan
 and close the engine compartment cover.
    (13) Five seconds after the  engine
 stops running, simultaneously turn off
 revolution  counter No.  2  and position
 the sample solenoid valves to the "dump"
 position.  As soon as possible and in no
 case longer  than  20 minutes after the
 end  of this  portion  of the test discon-
 nect the "stabilized" exhaust and dilu-
 tion  air sample  bags, transfer them  to
 the analytical system and process the
 samples-according to ! 85.075-23.
   (14)  Immediately  after the end of the
 sample period, disconnect the exhaust
 tube from the tailpipe (s), turn off the
 cooling fan  and close the engine com-
 partment cover.
   (15)  Turn off the positive displace-
 ment pump.
   (16)  Repeat  the  steps  In subpara-
.graphs (2)  through  (10)  of this para-
 graph for the hot start test except only
 one evacuated sample bag is required for
 sampling exhaust gas and  one for dilu-
 tion air. The step in subparagraph (7) of
 this paragraph shall begin between 9 and
 11  minutes  after the end of the sample
 period for the cold  start test.
   (17) At the end of the deceleration
 which is scheduled to occur at 505  sec-
 onds, simultaneously turn off the No. 1
 revolution counter and position the sam-
 ple solenoid  valve  to the "dump" posi-
 tion.  (Engine shutdown is not part of the
 hot start test sample period.)
   (18)  As soon as possible and  in no
case  longer  than 20 minutes after the
 end of this portion of the test disconnect
 the hot  start "transient" exhaust  and
dilution air  sample bags,  transfer them
to the analytical system and process the
samples according  to  I 85.075-23.
  (19) Disconnect  the   exhaust  tube
from  the vehicle tailpipe (s) and remove
vehicle from dynamometer.
  (20) The  positive displacement pump
may be turned off, if desired.

 § 85.075-27  Calculations (fuel evapora-
     tive emissions).

   The net weights of the individual col-
 lection traps  employed  in  § 85.075-13
 shall be  added together to  determine
 compliance  with  the fuel  evaporative
 emission standard.

 §85.075—28  Compliance witli  emission
     standards.
   (a)  The  exhaust  and  fuel  evapora-
 tive emission   standards in  § 85.075-1
 apply  to the emissions  of  vehicles  for
 their useful life.
   (b)  Since emission  control  efficiency
 decreases with  mileage accumulated on
 the vehicle,  the emission level of a  ve-
 hicle  which has  accumulated  50,000
 miles  will  be  used  as  the  basis  for
 determining   compliance  with   the
 standards.
   (c) The  procedure  for determining
 compliance of a new  light  duty  motor
 vehicle with exhaust and fuel evaporative
 emission standards is as follows:
   (1) Separate  emission deterioration
 factors shall be determined  from  the
emissions results of the  durability data
vehicles for  each engine-system combi-
nation. A separate  factor shall be estab-
lished  for  the  combination  for exhaust
HC, exhaust CO, exhaust NO., and fuel
evaporative HC.
   (1)  The  applicable results to be used
in determining the deterioration factors
for each combination shall be:
   (a) All emission data  from the tests
required under § 85.075-V(b). except the
zero mile tests. This shall  include the of-
ficial  test  results,  as  determined   In
§ 85.075-29, for all tests conducted on all
durability vehicles of the  combination
selected under 5 85.075-6 (c)  (including
all vehicles elected to be operated by the
manufacturer  under § 85.075-5(c) (3)).
Where  the  Administrator has agreed  to
a  mileage less than 50,000  miles in ac-
cordance with § 85.075-7 (b). the data for
mileages  greater than that  actually run
will be  determined by extrapolating the
test data generated at lesser mileages.
   (b) All emission data from  the tests
conducted before and after  the mainte-
nance provided in § 85.075-6(a) (1) (i).
   (ii) All applicable results  shall  be
plotted  as a function of the mileage on
the system, rounded  to the nearest mile.
and the best fit straight lines, fitted by
the' method of least squares,  shall  be
drawn  through these data  points. The
interpolated   4,000-   and  50,000-mile
points on this line must  be within the
standards  provided  in  §85.075-1  or
the data will not be acceptable for use in
calculation  of  a deterioration factor.
   (iii) An exhaust emission deteriora-
tion factor  shall be calculated for each
combination as follows:
                                                                 exhaust emissions Interpolated to 50,000 miles
                                                          f actor = exhaust emissions Interpolated to 4,000 miles
                                           (iv)  An evaporative emission  deteri-

 § 85.075-29  Testing by the Administra-
     tor.
   (a)  The  Administrator may  require
 that any one or more of  the test vehicles
 be  submited  to him,  at such place or
 places as he may designate, for the pur-
 pose of conducting emissions tests.  The
 Administrator may  specify  that  he will
 conduct such testing  at the manufac-
 turer's facility, in which  case instrumen-
 tation and  equipment specified  by the
 Administrator shall be made available by
 the  manufacturer  for test operations.
 Any testing conducted  at  a manufac-
 turer's  facility  pursuant to this para-
 graph shall be scheduled by the manu-
 facturer as promptly as possible.
  (b)(l) Whenever  the  Administrator
 conducts a  test on  a test  vehicle,  the
 results  of that  test  shall comprise  the
 official data for  the vehicle  at that pre-
 scribed  test  point.
  (2) Whenever the Administrator does
 not conduct a test on a test vehicle at a
 test point, the manufacturer's test data
 will be  accepted as the official data for
 that test  point: Provided,  That if  the
 Administrator  makes  a  determination
 based on testing under paragraph (a) of
 this section, that there is a lack  of cor-
 relation between the manufacturer's test
 equipment and the test equipment used
 by the Administrator, no manufacturer's
 test data will be accepted for purposes of
 certification  until the reasons  for  the
 lack of  correlation are determined and
 the validity  of the data is established by
 the manufacturer.
  (3) If the  Administrator  determines
 that the test data developed under para-
 graph (a) of this section would  cause a
 vehicle to fail due to  excessive 4,000-mile
or excessive deterioration, then the fol-
lowing procedure shall be observed:
  (1)  The manufacturer  may request a
retest. Before the retest, the vehicle may
be adjusted to manufacturer's specifica-
tions, and parts may be  replaced in ac-
cordance with § 85.075-6.  All work on the
vehicle  shall be done at such location
and under such conditions as the Admin-
istrator may prescribe.
  (il) The vehicle will be retested by the
 Administrator and the results of this test
shall comprise the official data for that
 prescribed test point.
   (4)  If sufficient durability data is not
 available, at the time  of  any emission
 test conducted under paragraph (a) of
 this section, to enable the Administrator
 to determine whether a test vehicle would
 fail, the manufacturer may request a re-
 test in accordance with the provisions of
 subparagraph  (3)  (i)   and (ii)  of  this
 paragraph. If the manufacturer does not
 promptly make such request, he shall be
 deemed to have  waived the right to  a
 retest. A request for retest must be made
 before  the  manufacturer  removes  the
 vehicle from the test premises.

 § 85.075-30  Certification.
   (a)  (1) If, after a review of the  test
 reports and data submitted by the manu-
 facturer and data derived from any addi-
 tional testing  conducted  pursuant to
 § 85.075-29.  the  Administrator  deter-
 mines that a test vehicle(s) conforms to
 the regulations of  this subpart,  he  will
 issue  a  certificate of  conformity  with
 respect to such vehlcle(s).
   (2)  Such certificate will be issued for
 such period not more than 1 year as the
 Administrator  may determine and upon
 such terms as he may deem necessary to
 assure that any new motor vehicle cov-
 ered by the certificate will meet  the re-
 quirements of these regulations relating
 to durability and performance.
   (b)(l)  The Administrator will deter-
 mine  wther  a vehicle, covered by  the
 application   complies   with  applicable
 standards  by  observing  the following
 relationships:
   (i) A   test  vehicle  selected  under
 § 85.075-5(b) (2) or (4), shall represent
 all vehicles in the same engine family of
 the  same engine  displacement-exhaust
 emission   control   system-evaporative
 emission control system combination.
   (ii)  A  test  vehicle  selected  under
 § 85.075-5(b)(3),   shall represent  all
 vehicles In the same engine family of the
 same engine displacement-exhaust emis-
 sion control  system-transmission type-
 fuel system combination.
  (ill) A test vehicle selected under § 85.-
 075-5(c)(l), shall represent all vehicles
 of the same engine-system combination.
  (2) The Administrator will proceed as
 in paragraph (a)  of this section with re-
 spect to the vehicles belonging to an en-
 gine  family all of which  comply with
 applicable standards.
  (3) If, after  a  review of the test re-
 ports and data submitted by the manu-
 facturer  and  data  derived  from  any
 additional testing conducted pursuant to
 § 85.075-29,  the  Administrator  deter-
 mines that one or more test vehicles of
 the certification test fleet  do not meet
 applicable standards, he will notify  the
 manufacturer in  writing, setting forth
 the basis for his  determination. Within
 30 days following  receipt of the notifica-
tion,  the  manufacturer may request a
hearing on the  Administrator's determi-
nation. The request shall be  in writing,
signed by an authorized representative
of the manufacturer and shall include a
statement specifying the manufacturer's
objections to the  Administrator's deter-
mination, and  data in  support of such
objections. If, after a review of the re-
quest and supporting data, the Adminis-
 trator finds that the request raises  a
 substantial factual issue, he shall provide
 the manufacturer a hearing in accord-
 ance with § 85.005 with respect to such
 issue.
   (4)  The manufacturer may,  at  his
 option, proceed with any of the following
 alternatives with respect to any engine
 family represented by  a test vehicle(s)
 determined not in compliance with ap-
 plicable  standards:
   (i)  Request  a hearing under § 85.005,
 or
   (ii)  Delete from  the application  for
 certification the vehicles represented by
 the failing test vehicle.  (Vehicles so de-
 leted may be included in a later request
 for certification under  § 85.075-32.) The
 Administrator will then select in  place
 of each  failing vehicle an alternate  ve-
 hicle chosen in accordance with selection
 criteria employed in selecting the vehicle
 that failed, or
   (iii) Modify the test vehicle and dem-
 onstrate  by testing that it meets appli-
 cable  standards. Another vehicle  which
 is in  all material respects the same as
 the first vehicle, as modified, shall then
 be operated and tested in accordance
 with applicable test procedures.
   (5)  If  the manufacturer does not re-
 quest  a  hearing or present the required
 data  under subparagraph (4) of this
 paragraph, the Administrator will deny
 certification.
 § 85.075-31   Separate certification.
   Where possible a manufacturer should
 Include in a single application for certifi-
 cation all vehicles for which certification
 is required. A  manufacturer may,  how-
 ever, choose to apply separately for cer-
 tification of part of his product line. The
 selection of test vehicles and the compu-
 tation of test results will be determined
 separately for  each application.

 § 85.075-32   Addition of a vehicle after
     Certification.
   (a)  If a manufacturer proposes to add
 to his  product line a vehicle of the same
 engine-system  combination as vehicles
 previously certified but  which was not
 described in the application for certifica-
 tion when the test vehlcle(s) represent-
 ing other vehicles of that combination
 was certified, he shall notify the Admin-
 istrator. Such notification shall be in ad-
 vance  of the addition unless the manu-
 facturer  elects to follow the procedure
 described in § 85.075-34. This notification
 shall include a full description of the
 vehicle to be added.
   (b)  The Administrator may require
 the manufacturer to perform such  tests
 on the test vehicle (s)  representing the
 vehicle to be added which would  have
 been required  if the vehicle  had  been
 included  in the original application for
certification.
  (c) If, after  a review of the test re-
ports and data submitted by the manu-
facturer, and data derived from any  test-
ing conducted under § 85.075-29, the Ad-
ministrator determines  that  the  test
vehicle(s) meets all applicable standards.
 the  appropriate  certificate   will   be
 amended  accordingly.  If the Adminis-
 trator determines that the test vehicle(s)

§ 85.075-33  Changes  to a vehicle  cov-
    ered by certification.
  (a)  The manufacturer shall notify the
Administrator of any change in produc-
tion  vehicles in respect to any of the
parameters  listed  in  § 85.075-5(a) (3),
giving  a full description of the chnage.
Such notification shall be in advance of
the change  unless  the manufacturer
elects to follow the procedure described
in 9 85.075-34.
  (b)  Based upon the description of the
change, and data derived from such test-
ing as the Administrator many require or
conduct, the Administrator will  deter-
mine whether the vehicle, as modified,
would  still  be covered  by the certificate
of conformity then in effect.
  (c)  If the Administrator determines
that the outstanding  certificate  would
cover the modified vehicles, he will notify
the manufacturer  in writing. Except as
provided in $ 85.075-34 the change  may
not be  put into  effect prior to the manu-
facturer's receiving this notification. If
the Administrator determines that the
modified vehicles would not be covered
by the  certificate then In effect, then the
modified vehicles shall be treated  as ad-
ditions  to  the  product line  subject to
§ 85.075-32.
§ 85.075-34  Alternative procedure for
    notification of additions and changes.
  (a)  A manufacturer may.  In  lieu of
notifying the Administrator in advance
of an addition of a vehicle under 8 85.705-
32 or a change  in a vehicle under § 85.-
075-33, notify him concurrently with the
making of  the  change If the manufac-
turer believes' the addition or change will
not require any testing under the appro-
priate  section. Upon notification  to the
Administrator,  the manufacturer  may
proceed to put the addition  or  change
into effect.
  (b)  The  manufacturer may continue
to produce vehicles as described in the
notification to  the  Administrator for a
maximum of 30 days, unless the Admin-
istrator grants  an  extension in writing.
This period may be shortened by a notifi-
cation  in accordance with paragraph (c)
of this section.
  (c)  If the Administrator determines,
based upon a description of the addition
or change,  that no test data will  be re-
quired, he will  notify  the manufacturer
in writing of the acceptability of the ad-
dition  or change.  If the Administrator
determines that test data will be required,
he will notify the manufacturer  to re-
scind the change within 5 days of receipt
of the  notification. The Administrator
will then proceed as in $85.075-32 (b)
and (c), or (85.075-33 (b)  and  (c) as
appropriate.
  (d)  Election to produce vehicles under
this section will be deemed to be a con-
sent to recall all vehicles which the Ad-
ministrator  determined under 5 85.075-
32(c) do not meet applicable standards,
and to cause such nonconformity to be
remedied at no expense to the owner.

               APPENDIX II
PROCEDURE  FOR DYNAMOMETER BOAO  HORSE-
            POWER CALIBRATION

  This appendix describes the method for de-
termining the road horsepower absorbed by
a chassis dynamometer.  The measured ab-
sorbed road horsepower  Includes the dyna-
mometer friction as well as  the power ab-
sorbed by  the  power absorption unit.  The
dynamometer is driven above the test speed
range. The device used to drive the  dyna-
mometer is then disengaged from the dyna-
mometer and the roll (a)  is allowed to coast
down. The kinetic energy of the system  is
dissipated by the dynamometer friction  and
absorption unlit. This method neglects the
variations In roll bearing friction due to the
drive axle weight of the  vehicle. The differ-
ence in coast down time of the free (rear)
roll relative to the drive  (front)  roll may be
neglected In the case of dynamometers with
paired rolls.
  These procedures shall be followed:
  l.  Devise a method to determine the speed
of the drive roll if not already measured. A
fifth  wheel,  revolution  pickup  or  other
suitable means may be used.
  2.  Place a vehicle on the dynamometer or
devise  another  method  of driving  the
dynamometer.
  3.  Engage Inertia flywheel for the most
common vehicle weight class for which the
dynamometer Is used.
  4.  Drive  dynamometer  up to 60 m.p.h.
  5.  Record Indicated road  horsepower.
  6.  Drive dynamometer up to 60 m.p.h.
  7.  Disengage  the device used to drive the
dynamometer.
  8.  Record the time  for the dynamometer
drive roll to coast down from 66  m.p.h. to
45 m.p.h.
  9.  Adjust the power absorption unit to a
different level.
  10. Repeat steps  4  to  9 above  sufficient
times to cover the range  of road horsepower
used.
  11. Calculate absorbed road  horsepower
from:
  HP4=(l/2)(W,/82.2) (V,'-V,«)/(860t)
  HPd = 0.06073  (Wt/t)
Where:
  W, = Equivalent Inertia In Ib.
   V,=Initial velocity in ft. /sec. (66 m.p.h.
         =80.87ft./sec.).

                 SYSTEM
  The chemllumlnescence  method  utilizes
tbe principle that nitric oxide  (NO) reacts
with  ozone  (O,)  to give nitrogen  dioxide
(NO,) and oxygen  (O,). Approximately  10
percent of the NO,  la electronically  excited.
The transition of excited NO, to the ground
state  yields a detectable  light emission (690-
630 nanometer region) at low pressures. The
Intensity of  this emission Is proportional  to
the mass flow rate of NO Into the reactor. The
light  emission  can  be measured   utiliz-
ing a photomultipUer tube and  associated
electronics.
  The method also utilizes the principle that
the thermal decomposition  of NO,  (2NO,-»
2NO+O,)  Is complete at about  600° O. The
rate   constant  for the dissociation  of NO,
at 600* C. la approximately  10° (liters/mole-
second). A 6-foot length of one-eighth Inch
outside diameter, 0.028 wall  thickness, flaw-
less stainless steel tubing resistance heated
using a low voltage, high current power sup-
ply to a temperature of 660° C. (1200* F.)
provides sufficient residence time at a sample
flow rate of 700 cc. per  minute  (1.6 c.fi.)
for essentially complete conversion of nitro-
gen dioxide to nitric oxide. Other converter
designs may be used If shown to yield essen-
tially  100 percent conversion of NO, to NO.
  The method  permits continuous monitor-
Ing of NO. concentrations over a wide range.
Response time (3 to 4 seconds Is typical)  Is
primarily  dependent  on the  mechanical
pumping' rate at  the operating pressure  of
the reactor.  The operating  pressure of the
reactor la generally less than 6 torr.
  The following  figure Is a  flow schematic
Illustrating one configuration of the major

16. ABSTRACT
 A  group of 50 trucks,  of model years  1965 to 1973, 6,000  to 16,000 Ibs gross  vehicle
 weight were tested  for exhaust and evaporative emissions  using a modified  light duty
 procedure.  The results from these tests, together with other similar tests  initiated
 by the Environmental  Protection Agency,  will form the baseline emissions data for this
 test procedure.  The  group of trucks  which was assembled  for these tests was  suffi-
 ciently varied to contribute to a proper baseline.  All trucks completed the  test pro-
 cedure successfully,  however, it appears that some adjustment in road load  power
 settings may be required at dynamometer  inertia settings  above 8,500 Ibs.
