I. SUMMARY
Five light duty vehicles representing manufacturers' current
emission control systems were used to investigate emission and fuel
economy sensitivity to changes in current test procedrues for light
duty vehicles. Length of soak period preceding the EPA Urban Dy-
namometer Driving Schedule (UDDS), and speed versus time charac-
teristics of the EPA highway fuel economy test (HFET) and UDDS were
also varied.
Tests using the UDDS were run following soak periods of 36,
16, 8, 4, 2, 1, 1/2, 1/3, and 1/6 hours, and tests using the modified
UDDS (MUDDS) were run following 16 and 1/6 hour soak periods to
simulate cold start and hot start conditions, respectively. Highway
cycles were run following a 10 minute soak period preceded by a
minimum of one urban driving cycle. During the first 505 seconds of
each test using the urban driving cycles, eight CVS sample bags were
taken, each representing the average dilute exhaust concentration
for a period of approximately one minute. During all dynamometer
tests, and during soak periods preceding tests used in the analysis
of soak period length effects, the temperatures of five components
on each vehicle -were measured and continuously recorded.
To eliminate as many variables as possible, the testing of
each vehicle -was done following identical test plans. The order of
tests used in the analysis of soak period length effects was reversed
for one vehicle to investigate what differences, if any, would result.
An engineering review of the laboratory results indicated the following:
1. ) Emission results and fuel consumption during the UDDS were,
with a few exceptions noted below, consistently and logically
affected by soak period length. The following are general
observations from the data.
a. ) HC increased with increases in soak period length
over the entire range of soak periods tested.
b. ) CO emission rates were constant following soak
periods of one hour and less, and increased sharply
with longer soak periods over the range of 2 to 36 hours.
c. ) NOX emission rates were constant following soak periods
of 10 to 30 minutes in length, were constant but, slightly
higher following soak periods of one to four hours in
length, and were constant and again higher following
eight hour and longer soak periods.
-------
d. ) Fuel consumption increased very slowly with increases
in soak period length in the 10 minute to one hour range,
and increased gradually with longer soak periods of two
hours and longer.
e.) The effect of varying the order of tests following different
length soak periods could not be seen in emission rates
or fuel consumption. When shorter soak period tests
were run following only one preconditioning urban cycle
rather than several, the only result was that fuel tank
temperatures had not reached a steady value.
2. ) Statistical "t" test comparisons of results obtained using modi-
fied and baseline urban and non-urban driving cycles did not
indicate a consistent statistical difference for all vehicles
tested. Some general observations from test data are offered ,
however, for consideration.
a. ) HC results were both higher and lower during the MHFET
as compared to baseline values. CO and NOX were higher
during the modified cycle, and fuel consumption showed
a very slight increase over baseline cycle values.
b. ) HC and NOX were significantly different during the MUDDS
following a 16 hour soak for a majority of the vehicles,
but both higher and lower values were observed. CO and
fuel consumption were not significantly different for a
majority of the cars tested.
c. ) During the MUDDS following a 10 minute soak, the emis-
sion rates were significantly different from those during
the UDDS for each car, but again, individual tests showed
increases and decreases. CO emission rates were not
significantly different for a majority of the cars tested.
NOX and fuel consumption were significantly different
from baseline results for a majority of the cars tested,
and each showed a very minute increase during the modi-
fied cycle.

II. INTRODUCTION
On May 6, 1976, Task Order No. 10 titled, "Emissions and Fuel
Economy Sensitivity to Changes in Light Duty Vehicle Test Procedures"
was authorized by the EPA Contracting Officer of Contract 68-03-2196,
Mr. Albert W- Ahlquist. The project consisted of a laboratory task
plus final reporting.
The scope of work and plan of test were sufficiently developed so
that little input by SwRI was needed. SwRI functioned mainly as a test
laboratory and provided statistical analysis of the data as specified.
-------
III. OBJECTIVE AND PLAN OF TEST
This section briefly describes the preparations and experimental
plan, procedures and equipment, vehicles and fuel employed.
A. Objective
The objective of this project was to determine the exhaust emis-
sion and fuel economy sensitivity to changes in current test procedures
for light duty vehicles. Speed versus time characteristics and length
of soak period were varied for the EPA Urban Dynamometer Driving
Schedule (UDDS), and the speed versus time characteristics of the EPA
Highway Fuel Economy Test (HFET) were also varied. Five vehicles
representing current vehicle populations and emission control systems
were tested following similar test sequences.
B. Scope
The scope of work included vehicle procurement, inspection,
testing and statistical analysis plus the preparation of a final report.
Basically, the experimental effort for each vehicle consisted of 24
emission tests using urban driving schedules and six highway fuel
economy tests. The analytical effort included statistical comparisons
of fuel economy and emission results obtained with modified and base-
line driving cycles.
*
C. Vehicle Selection
As specified by the Task Order, the five vehicles tested in this
project were:
(1) one current model year GM automobile, large
displacement engine, high inertia weight, pelleted
oxidation catalyst
(2) one current model year Ford automobile, large
displacement engine, high inertia weight,
monolith oxidation catalyst
(3) one current model year Chrysler automobile,
large displacement engine, high inertia weight,
monolith oxidation catalyst
(4) one current model year automobile, small
displacement engine, low inertia weight,
oxidation catalyst
-------
(5) one- current model year vehicle, small displacement
CVCC engine
The actual vehicles tested are described in Table 1. Each of
the vehicles, all in some stage of testing, are shown in Figure 1.
These vehicles were as described in the original Scope of Work with
the exception of the Chrysler automobile. In a telephone conversation
with the Task Officer July 9, 1976, it was pointed out that a non-
catalyst Chrysler automobile, as originally suggested, was rather
difficult to locate and was not a common car. In a telephone conver-
tion July 12, 1976, the Task Officer requested that a catalyst equipped
Chrysler automobile be tested instead.
D. Vehicle Preparation
Prior to rental of each vehicle, the vehicle and engine were
given a visual examination to make certain that the components and
exhaust system were intact insofar as they could be observed. En-
route to SwRI and prior to acceptance of the vehicle for use in this
project, the driveability and general road performance of the vehicle
were observed to ensure that the engine and car performed satisfac-
torily.
Next, the vehicle engine was subjected to a tune check to make
certain all manufacturer's recommendations were met. These
vehicles were all relatively new and therefore a tune-up, in which
parts were replaced, was neither necessary nor was it desired.
The tune check was to make certain the engines were within factory
tolerances of basic spark timing, idle rpm, and idle mixture setting.
On the Honda Civic, the only vehicle tested which did not have an
electronic ignition system, the distributor dwell was also checked.
If these parameters were not within the manufacturer's limits, they
were adjusted prior to the beginning of testing.
As a further check on the condition of each vehicle, a three-bag
1975 FTP, from cold start, was run. Because all tests in the actual
experiment were either highway cycles or two bag urban cycles, this
additional test was conducted to compare each vehicle with certifica-
tion levels and applicable statutory limits.
During these inspections, it was determined that all original
equipment was intact and apparently functioning satisfactorily. The
Chevrolet Vega was discovered to have an apparently clogged air
cleaner element, which resulted in extremely high CO values during
the initial emission test. With this exception, no parts were replaced
on any of the vehicles.

If the vehicle proved acceptable up to this point, it was then
instrumented to measure carburetor inlet air, engine water out, oil
pan, fuel tank vapor, and fuel tank liquid temperatures. Typical
thermocouple installations are shown in Figure 2. Carburetor inlet
air was measured inside the air cleaner at the top of the carburetor
air horn, approximately in the center of the air inlet. This was done
on each vehicle by passing fine thermocouple wire through the air
cleaner cover adjacent to the air cleaner anchor screw. Engine
water-out temperature was monitored by adapting the upper radiator
hose to facilitate thermocouple installation, and a dipstick thermo-
couple was used to measure oil sump temperature. The filler neck
shown in Figure 2 is the tank end of the neck. When inserted in the
fuel tank, the thermocouple adjacent to the neck measured vapor
temperature, and the longer thermocouple wire was submerged in
liquid fuel. A different method was used on the Honda Civic, which
had fuel tank connections that allowed simpler thermocouple instal-
lation.
E. Test Sequence
The experimental test plan followed for each car is outlined in
Table 2. Part I of the test plan covers experiments to compare EPA
baseline driving cycles to modified cycles. The modified UDDS (MUDDS)
consists of the same segments as the UDDS, but the segments are re-
arranged to occur in a difference sequence . The total time and distance
traveled are the same for both cycles. The modified highway cycle
had a top speed of 116 kilometres per hour (72 mph), an average speed
of 80 kilometres per hours (49.7 mph) and covered 17.0 kilometres
(10. 56 miles). For comparison, these values for the HFET are 92
(57), 78 (48), and 16.5 (10.24) respectively. The time elapsed during
both cycles is the same. Part II of the test plan covers tests used to
study the effect of soak period length on emission rates and fuel economy
during the UDDS. Tests were conducted following soak periods of 36, 8,
4, 2, 1, 1/2, 1/3 and 1/6 hours.
As specified in the Scope of Work, three replicates were run for
each highway cycle and for urban cycles following 16 hour soak periods.
Two replicates were made of all other tests. The results of the 16 hour
soak tests using the UDDS were used both in comparisons of modified
and baseline driving cycles and in the study of soak period length effects.
The 10 minute soak UDDS tests in part II were also used in the comparison
of modified and baseline cycles.
To avoid differences between the testing of each vehicle, all
tests were performed in the sequence listed in Table 2, grouping

ditioning and the prescribed sequence of soak periods and tests
resumed.

-------
tests each day in the same manner for each car. In the event a par-
ticular test was repeated for any reason, the vehicle was precondi-
tioned to a state comparable to the original sequence.
For the Ford LTD, tests used in the portion of the experiment
evaluating different length soak periods were performed in the sequence
opposite that in Part 2 of the experimental test plan. Tests following
the shorter soak periods were conducted first, followed by tests using
longer and longer soak periods. This was done at the request of the
Task Officer to investigate the effects of different evaporative emis-
sion system loading.
F. Test Procedures and Equipment
Minimal test-to-test variability was considered very important
in the conduct of this project. To this end, the same laboratory equip-
ment, driver, analytical cart, and CVS were used throughout. Prior
to each test sequence, the vehicle was given a preconditioning run on
the chassis dynamometer following the driving cycle to be used in the
following test. Tests using the UDDS were preceded by a UDDS, and
tests using the MUDDS were preceded by an MUDDS. Highway Fuel
Economy Tests (HFET) were preceded by a UDDS, and tests using the
modified HFET cycle (MHFET) were preceded by an MUDDS.
All exhaust emission test work was done in accord with the
method specified in 40CFR 85. 075 with the exception of evaporative
emission testing, which was of no interest to this project. In addition
to the exhaust emission testing for gaseous emission in terms of the
1975 FTP (HC, CO,and NOX ), fuel economy by the carbon balance
method was also determined.
Temperature Measurement
Carburetor inlet air, engine water out, oil pan, fuel tank vapor,
and fuel tank liquid temperatures were continuously recorded during
all emission and fuel economy tests and during the soak periods prior
to emission tests used in the analysis of the effects of soak period
length. These temperatures, measured with iron-constantan thermo-
couples, were continuously recorded using a six pen recorder. The
sixth pen on the recorder was used to record vehicle miles per hour.
In addition to this temperature record, the output of each thermocouple,
corrected for room temperature, was electronically integrated during
all tests and applicable soak periods, allowing an average emf to be
calculated. Over the narrow range of temperatures encountered,
the output of the I-C thermocouple is approximately linear, making it
12
-------
possible to determine an average temperature from the average emf.
Various views of the temperature measuring apparatus can be seen
in Figure 1.
Sequential Sampling
During the first 505 seconds of UDDS and MUDDS, in addition
to the 505 second exhaust sample, eight CVS bag samples were collected,
each representing the average concentration for a 63 second segment of
the driving cycle. The period represented by each bag, the distance
traveled, and the average speed in each period are shown in Table 3.
Figure 3 is a speed versus time plot of the first 505 seconds of each
driving cycle with the 63 second divisions shown.
The CVS used was modified to allow a continuous sequence of
dilute exhaust sample bags to be taken in addition to the two sample
bags normally taken. To simplify analysis, the values from the 505
second background sample were used in the calculation of mass emis-
sions from the sequential samples. A schematic of the modified CVS
is shown in Figure 4. The revolutions of the positive displacement pump
and time were measured during each of the sequential samples, allowing
an accurate determination to be made of gaseous emissions on a mass
basis for each period. Figure 5 shows various views of the sequential
sampling system in operation.
Diagnostic Checks
To rule out changing engine tune parameters as a source of
variability, engine diagnostic checks were performed with a frequency
of approximately every fifth emission test, as indicated in Table 2.
The diagnostic checks included idle rpm, ignition timing, and distri-
butor dwell if applicable. Throughout testing, no change in these
parameters could be measured in any of the vehicles. Thus, no
adjustments of any kind were made to the vehicles once testing had
begun.
G. Test Fuel
Vehicle 5, the 1976 Honda Civic CVCC, was not equipped with
an oxidation catalyst in the exhaust system. To eliminate fuel as a
variable in the experiment, all vehicles were run on unleaded fuel.
Table 4 lists the properties of the fuel used. The fuel met the require-
ments of 40CFR 85.075-10 for unleaded exhaust and evaporative emis-
sion test gasoline.

IV. DISCUSSION
In this section, the emission and fuel economy results of tests
on the five cars are presented and discussed as a group. Comments
are made regarding the effects of soak period length on each exhaust
constituent and on fuel consumption during the UDDS. The effects of
varying segment order in the UDDS, and varying the speed versus
time characteristics of the HFET on exhaust emissions and fuel
economy are discussed for the five cars as a whole by comparing
results obtained with modified driving cycles to those of baseline
cycles. The statistical comparisons of results of baseline and modi-
fied cycles are summarized and commented on.
A. Length of Soak Period
Emission rates and fuel consumption for each vehicle tested
following soak periods of 36, 16, 8, 4, 2, 1, 1/2, 1/3, and 1/6 hours
are shown in Figures 7 and 8. Values plotted for each car are as
percent of average results obtained following a 16 hour soak period. Thus,
results are normalized to the 16 hour soak which is typically the
overnight soak period for emission testing.
HC emission rates were very strongly, and fairly predictably,
affected by soak period length over the entire range of soak lengths
tested. With the exception of only one car of the five tested, HC
values following soak periods of eight hours and less were lower than
the 16 hour value. With only one exception, values following a 36
hour soak period either equalled or exceeded results following a 16
hour soak. HC emission rates increased fairly sharply with increase
in soak period length.
CO emission rates were affected strongly, and somewhat system-
atically by soak period length. With few exceptions, CO was moder-
ately constant following soak periods of up to two hours. The CO
values in this interval for the Honda Civic were greater in propor-
tion to the 16 hour soak values than was the case for the other cars.
Very likely this is a result of the Honda not being catalyst equipped,
as were the other four cars. CO emission rates following 4 hour
and longer soak periods increased sharply with soak period length
for all vehicles. With only one exception, CO was higher following a
36 hour soak than following a 16 hour soak period.
NO emission rates were strongly a function of soak period
length, increasing with increases in soak length. The NOX values
for the Ford LTD did not follow as orderly a progression as did
values for the other vehicles. Because NOX following a 16 hour soak
period was somewhat lower than all other values for that car, the

normalized results for the LTD are high, and appear to show con-
siderable scatter. If the 16 hour soak results had been higher, then
data for the Ford would possibly have fallen in line with the other
values.
Fuel consumption, even though not affected to as large an ex-
tent as emission rates, increased almost methodically with increases
in soak length. The variation at each length soak period was fairly
small, with most conditions showing a range of 10 percent or less.
The strong effect soak period length had on emission rates
and fuel consumption can be seen from Figures 7 and 8. Also, because
the data taken in sequential samples agrees with the cold transient re-
sults, the sequential samples show this effect. The effect of soak
length is fairly predictable; emission rates and fuel consumption in-
crease with soak length for the range of soak periods investigated.
B. Modified Versus Baseline Driving Cycles
A summary of statistical "t" test comparisons of emission
rates and fuel consumption during baseline and modified driving
cycles for each car are shown in Table 5. In a few instances
the majority of the vehicles show a statistical difference between
two cycles that is consistent in sign convention. The NOX values
during the MHFET were statistically different for four cars, and the
difference is an increase over baseline values in each case. Following
a 10 minute soak period, the statistical test indicated a difference in
NOX between the UDDS and MUDDS for all five cars, and four of those
vehicles showed an increase. Also following a 10 minute soak period,
the "t" test indicated a difference in fuel consumption between the
two urban cycles for four cars. The difference was an increase for
all four cars.
Caution should be used in considering these statistical com-
parisons. Although the "t" test indicates that a difference actually
does exist, the significance of that difference from a practical view-
point is equally, if not more, important. The proportion of the re-
sulting difference to results from the baseline driving cycle is shown
in Table 5 as the percent of average baseline cycle results. In many
cases, especially fuel consumption, differences are 10 percent or
less of the actual average value. As an illustration, fuel consump-
tion during the HFET averaged 10. 29 £. /I 00 km for the five vehicles.

-------
In proportion to this, the nominal 0.45 &/100 km difference is re-
markably small. Another point to consider is the number of replica-
tions of each test. Only two replications of the UDDS and MUDDS
(following 10 minute soak periods), three replications of the HFET
and MHFET (following a 10 minute soak) and three replications of the
UDDS and MUDDS (following 16 hour soak periods) were run for each
car. Even though the "t" test is valid for small samples, results
obtained from this number of tests could be misleading.
Figure 9 shows results of the MHFET, and Figure 10 shows
results of the MUDDS following 10 minute soak periods and l6 hour
soak periods. In these figures, results of the modified cycles are
plotted as a percent of the results obtained with the baseline cycles
they are being compared to.
For the MHFET, CO and NOX were distinctly higher than base-
line cycle values for a majority of the cars tested. No change in fuel
consumption was noted. For the MUDDS following a 10 minute soak
period, both NOX and fuel consumption were higher for four cars than
during the baseline cycle, but the greatest increase was approximately
11 percent in both cases. Following a 16 hour soak, no emission rate
or fuel consumption was higher during the MUDDS for more than three
of the cars. No fuel consumption difference was observed between
tests with the baseline and modified highway driving cycles. Emission
results from tests using baseline and modified emission test cycles did
not show consistent differences.

V. RESULTS
In this section, emission and fuel economy test results are
presented for each car individually. The effect of soak period length
on emission results and fuel consumption for the UDDS are discussed
for each vehicle, and the effect of changing "segment order" is dis-
cussed by comparing values obtained with a modified driving cycle to
those obtained with the UDDS. The effect of varying the speed vs
time characteristics of the HFET are discussed by comparing emis-
sion rates and fuel consumption obtained using a modified cycle to
that obtained with the HFET. Statistical comparisons of baseline and
modified cycles are presented for each vehicle. Because of the large
amount of data collected in this project, some test results referred
to in the text are summarized in detail in the appendices.
A. Car Number 1 - 1976 Chevrolet Impala
The results with car number 1 are described in terms of various
effects, such as the soak period length and cycle modifications in the
following subsections.
1. Length of Soak Period
Bar graphs of emission rates and fuel consumption during
the UDDS and MUDDS following each length soak period are shown in
Figures 11 and 12.In all bar graphs, the bar is the average of two or
more tests and the horizontal lines above and below the bar represent
actual test values. An exception to this is when three replicates of a
test were made, in which case the horizontal lines are the high and low
values. In Appendix Table A-2, results of all tests, including emission
rates and fuel consumption for each bag sample, are tabulated and
averages are calculated for each portion of replicate tests. Table A-l,
as do Tables B-l, C-l, D-l, and E-l for each vehicle, lists numbers
corresponding to dynamometer tests at each condition.
As shown in the figures, HC emission rates were approximately
equal following soak periods of 1 0 and 20 minutes, and increased sharply
with longer soak periods from 30 minutes to two hours in length. HC
was approximately the same following soak periods of two, four, and
eight hours, and slightly higher following l6 hour and 36 hour soak
periods. There was not a substantial difference between the HC emis-
sion rates following 16 hour and 36 hour soak periods. CO emission
rates were approximately equal following soak periods of 1 0 minutes to
one hour in length. Following soak periods from two to eight hours
long, CO increased sharply with longer soak periods. The CO emission
rates following l6 hour and 36 hour soak lengths were much higher than

following the eight hour soak, but the value following the 36 hour soak
was slightly lower than that following the i6 hour soak.
NOX emission rates and fuel consumption increased gradually
following longer soak periods over the entire range of soak periods
examined with a few exceptions. NOX emission rates did not increase
with soak period lengths of 8 hours and longer; and fuel consumption did
not increase following soak periods of 16 hours and longer.
Emission rates and fuel consumption for the 505 second and 867
second portions of the UDDS following each length soak period are
shown in Figures A-l and A-2 in Appendix A. As shown in the figures,
HC emission rates during the first 505 seconds of the cycle increased
gradually with longer soak periods in the 10 minute to two hour range,
and were approximately equal following soak periods of two to eight
hours in length. Following soak periods of 16 and 36 hours, HC in the
first 505 seconds was considerably higher, but the 36 hour value was
slightly less than the 16 hour value. The HC emission rates in the
last 867 seconds of the cycle showed a gradual, but very small, in-
crease with longer soak periods.
CO emission rates in the first 505 seconds of the UDDS were fairly
constant following soak periods of 10 minutes to one hour in length. Fol-
lowing soak periods of two to eight hours, CO in this segment increased
gradually with longer soak periods. Following soak periods of 16 and 36
hours, CO in this portion of the cycle was substantially higher, but the
value following a 36 hour soak was slightly less than that following a 16
hour soak period. During the last 867 seconds of the cycle, CO emission
rates were not strongly a function of soak period length, but the overall
trend was to increase slightly with longer soak periods.
NOX emission rates in the first 505 seconds of the UDDS increased
slightly with longer soak periods over the entire range of soak periods
tested. During the last 867 seconds of the cycle, NOX emission rates
were fairly constant. Although some deviation can be seen, these trends,
in general, hold true. Fuel consumption during both portions of the cycle
followed a general trend of increasing with longer soak period lengths,
with the trend being more noticeable in the first 505 seconds.
2. Comparison of Modified and Baseline Driving Cycles
A "t" test was used to test for a significant difference in emis-
sion rates and fuel consumption between modified driving cycles and
baseline cycles. The degrees of freedom (v), t value for a 95 percent
confidence interval (.975tv), difference between the means of the two
samples (d), the standard error of the difference (S^), and the t value
calculated for each case for the Chevrolet Impala are listed in Table 6.

For each case, a significant difference is defined as the calculated t
being greater than the t for a 95% confidence interval. In the case of
the highway cycles, the test showed significant differences between
HC and CO emission rates and fuel consumption. HC and CO were
lower in the modified cycle, while fuel consumption -was lower in the
baseline cycle, as shown in Figure 13. In the figure, the three bars
are the actual values from each test, and the horizontal slashed lines
are the average of the three values. Actual test values are listed in
Appendix A as Table A-3.
For the urban cycles run on the Chevrolet Impala, the "t"
test showed significant differences in HC and NOX emission rates be-
tween the two cycles following the 16 hour soak period, with lower
values in the modified cycle in both cases. For tests following 10
minute soak periods, a "t" test showed significant differences in HC
and NOX emission rates and fuel consumption between the two cycles;
each value being higher for the modified cycle. A graphic comparison
of emission rates and fuel consumption during the two cycles can be
seen in Figures 11 and 12, where results from the modified driving cycle
are plotted alongside baseline results.
3. Repeatability Between Replicate Tests
Table 7 contains emission rate and fuel consumption results
from all emission and fuel economy tests and the mean (X), standard
deviation (Sx), and coefficient of variation (Cv) for tests at each con-
dition.
4. Temperature Measurement
The temperature data for the Chevrolet Impala is in Appendix
A. Table A-4 lists the maximum, minimum, and average temperatures
for each component and the averages for replicate tests. Figure A-3
shows the average temperatures for each component during each length
soak period. Also in Appendix A, Figures A-4 and A-5 are bar graphs
of average temperatures during transient cycles following specific length
soak periods. The related tabulated data is in Table A-5.
5. Sequential Bag Sampling
Emission rates and fuel consumption calculated using the eight
sequential bag samples from each test are tabulated in Appendix Tables
A-6 through A-l6. The total mass of each gas measured during the
eight bag sequence was compared to the mass measured with the 505
second bag for that test, and the difference is listed in the respective

tables of sequential results in Appendix A. The agreement with the 505
second bag was generally within 5%. Bar graphs of the eight bag se-
quences for each test condition, and bar graphs comparing the eight
bag sequences of the UDDS and MUDDS are also in Appendix A as Figures
A-6 through A-18.
B. Car Number 2 - 1977 Ford LTD
The following describes the major findings with Car No. 2
1. Length of Soak Period
Bar graphs of emission rates and fuel consumption during the
UDDS and MUDDS are shown in Figures 14 and 15. In Appendix B
results of all tests, including emission rates and fuel consumption
for each bag sample, are tabulated and averages are listed for each
portion of replicate tests in Table B-2.
As can be seen in the figures, HC emission rates increased
gradually with increases in soak period length of up to 2 hours, but
no definite trend in HC emissions can be seen in tests following soak
periods of 4 to 16 hours in length. The HC values following a 36 hour
soak period, however, are substantially higher than those following
a 16 hour soak. CO emission rates remained fairly stable following
soak periods of up to four hours. Following soak periods of 8 to 36
hours in length, CO increased sharply with increases in soak period
length.
NOX emission rates did not follow any particular trend with
changes in soak period length. Although variation was noticeable in
NOX rates following different length soak periods, the variation is
random and on an absolute scale is fairly small. Fuel consumption
following soak periods of 20 minutes to 4 hours in length was approxi-
mately constant. Following the 10 minute soak period, fuel consump-
tion was slightly lower, and following 8 hour and longer soak periods
was fairly constant and slightly higher than values measured following
soak periods in the 20 minutes to 4 hour range.
Emission rates and fuel consumption for the first 505 seconds
and the last 867 seconds of the UDDS following each length soak period
are shown in Figures B-l and B-2 in Appendix B. HC emission rates
during the first 505 seconds of the cycle were strongly related to soak
period length, increasing sharply with increasing soak period length in
the range of 1 0 to 30 minutes and generally increasing slightly with longer
soak periods in the range of 1 to 16 hours. The HC emission rate in
this interval was much higher following a 36 hour soak period than
following a 16 hour soak. HC emission rates in the last 867 seconds
of the cycle were fairly constant over the range of soak periods tested.

CO emission rates in the first 505 seconds of the UDDS were
very constant following soak periods of 10 minutes to 4 hours in length
but increased sharply with longer soak period in the 8 to 36 hour range.
CO in the last 867 seconds of the cycle was constant over the entire
range of soak periods tested.
NOX emission rates in the first 505 seconds and the last 867
seconds of the UDDS did not follow a particular pattern with variations
in soak period length. Variation is noticeable between tests following
different soak period lengths, but the variation is small relative to
the actual values. Fuel consumption in the first 505 seconds of the
cycle was nearly constant following soak periods from 20 minutes to
4 hours in length but was slightly lower following a 10 minute soak
and considerably higher following 8 hour and longer soak periods.
Fuel consumption in the last 867 seconds of the UDDS was fairly
constant following soak periods of 20 minutes and longer, but was
considerably lower following a 10 minute soak.
2. Comparison of Baseline and Modified Driving Cycles
A summary of the statistical comparisons of the baseline and modi-
fied driving cycles are shown in Table 8. For the highway cycles, a
"t" test showed significant differences between HC, CO, and NOX
emission rates. Average values for the modified cycle were higher
in each case, as shown in Figure 16- Although the figure appears
to show considerable variability in CO emission rates, the differences
between replicate tests are small on an absolute scale. For the modi-
fied cycle, which has the greater variability, the corrected sample
concentrations for the high and low values differ by only 18 ppm.
Actual test results are listed in Appendix B as Table B-3.
In the case of the urban cycles, a "t" test showed significant
differences in HC and NOX emission rates folio-wing the 16 hour soak
periods, with higher values in the modified cycle in both cases. For
tests following 10 minute soak periods, a "t" test indicated a signifi-
cant difference in HC and NOX emission rates and in fuel consumption,
with higher values in the modified cycle in each case. A graphic
comparison of the urban cycles can also be seen in Figures 14 and 15,
where results from the modified driving cycle are plotted alongside
baseline cycle results.
3. Repeatability Between Replicate Tests
Table 9 contains emission rate and fuel consumption results
from all tests and the mean, standard deviation, and coefficient of
variation for tests at each condition.

4. Temperature Measurement
In Appendix B, the maximum, minimum, and average for each
temperature are tabulated and the averages for replicate tests are
listed in Table B-4. Figure B-3 shows the average temperatures during
each length soak period. Also in Appendix B as Figures B-4 and B-5
are bar graphs of average temperatures during transient cycles following
specific length soak periods, and the related data is listed in Table B-5
in Appendix B.
As requested by the Task Officer in a telephone conversation
of February 9, 1977, when emission tests following different length
soak periods were run on the same day (using the preceding test as
preconditioning) the tests following shorter soak periods were run
first. This sequence is reversed from that used in testing other
vehicles in this project, where the longer soak period tests were run
first. Possibly as a result of this reversed sequence, fuel tank tem-
peratures were lower during the 10 minute soak periods and following
tests than in the 20 minute soak periods and following tests. This
relationship is also apparent between the 20 and 30 minute soak periods
and tests. This pattern is the reverse of that seen on the other vehicles
tested in this project, which were all tested with the sequence listed in
Table 2.
5. Sequential Bag Sampling
The emission rates and fuel consumption calculated using the
eight bag samples are tabulated in Appendix B in Tables B-6 through
B-16. The total mass of each gas measured during each eight bag
sequence was compared with the mass measured with the 505 second
sample bag, and the agreement was generally within five percent. The
actual figures for each test are listed in the tables of the respective
tests in Appendix B. Also in the appendix, as Figures B-6 through B-18
are bar graphs of the eight bag sequences of the UDDS and MUDDS.
C. Car Number 3 - 1976 Plymouth Fury
Following are the results of tests investigating soak length
effects and tests to compare results with modified and baseline driving
cycles.
1. Length of Soak Period
Emission rates and fuel consumption during the UDDS and MUDDS
are shown in bar graphs in Figures 17 and 18. In Appendix C, in Table
C-2, results of all tests, as well as emission rates and fuel consumption
for each bag sample, are tabulated and averages are calculated for each
portion of replicate tests.

I97b Plymouth Fury
4o
-------
As shown in Figures 17 and 18, slightly lower HC and substan-
tially lower CO emission rates were measured following soak lengths
of one hour and less. Although there was some detectable variation
between HC values following one hour and shorter soak periods and
between CO values following one hour and shorter soak periods, the
amounts of variation were small relative to the average values. HC
emission rates increased slightly with soak period lengths of two to
sixteen hours, but there was not a measurable difference between
values following sixteen and thirty-six hour soak periods. CO emis-
sion rates increased gradually with soak lengths from two to thirty-
six hours.
NOX emission rates were not notably affected by variation in
soak length over the range tested. Although some variation was
detectable between tests following different length soak periods, this
variation was no larger than the variation between replicate tests.
Fuel consumption decreased very slightly with shorter soak lengths
over the entire range of soak periods tested.
Emission rates and fuel consumption for the first 505 seconds
and the last 86? seconds of the UDDS following each length soak period
are shown in Figures C-l and C-2 in Appendix C. HC emission rates
for the first 505 seconds of the cycle decreased gradually with shorter
soak lengths of one hour and less. The HC values for this interval
following two hour and longer soak periods were notably higher than
those following shorter soak periods, and increased gradually with
longer soak periods. HC emission rates in the last 867 seconds of
the UDDS were not clearly affected by variation in soak period length.
CO emission rates during the first 505 seconds of the UDDS in-
creased very slightly with longer soak lengths in the 10 minute to one
hour range, and were substantially higher and increased sharply with
longer soak periods in the two to thirty-six hour range. CO emission
rates in the last 867 seconds of the UDDS following soak periods of one
hour and shorter were not notably affected by soak period length, but
increased gradually with the longer soak periods of from two to thirty-
six hours in length.
NOX emission rates in the first 505 seconds of the UDDS were
not noticeably affected by soak lengths of two hours and less, but were
slightly lower following soak periods of four hours and longer. NOX
emission rates during the last 867 seconds of the UDDS were fairly
constant following soak lengths of two hours and less, but were slightly
higher following soak periods of four hours and longer. Fuel consump-
tion during both portions of the UDDS increased slightly with increased
soak length over the entire range of soak lengths tested, with the in-
47
-------
crease in the last 867 seconds being very gradual and the increase in
the first 505 seconds being gradual, but more noticeable than in-the
last 867 seconds.
2. Comparison of Baseline and Modified Driving Cycles
Details of the statistical comparisons of emission rates and fuel
consumption during baseline and modified driving cycles are shown in
Table 10. For the highway cycles, the "t" showed significant differences
between HC, CO, and NOX emission rates and fuel consumption during
the two cycles. Average values for the modified cycle were higher in
each case, as can be seen in Figure 19. Emission and fuel consump-
tion values from tests using non urban cycles are listed in Table C-3
in Appendix C.
In the case of the urban cycles, a "t" test showed significant
differences in HC and NOX emission rates between the two cycles fol-
lowing i6 hour soak periods, with lower HC and higher NOX in the
modified cycle. A "t" test showed significant differences between HC,
CO and NOX emission rates and fuel consumption between the two
cycles following the 10 minute soak period, with lower HC, higher CO,
NOX and fuel consumption in the modified cycle. A graphic comparison
of the urban cycles can be seen in Figures 17 and 18, where results
from the modified driving cycle are plotted alongside the baseline
results.
3. Repeatability Between Replicate Tests
Table 11 contains the emission rate and fuel consumption re-
sults from all tests and the mean, standard deviation, and coefficient
of variation for tests at each condition.
4. Temperature Measurement
In Appendix C, the maximum, minimum, and average tempera-
tures for each component are tabulated, and average temperatures are
listed for replicate tests in Table C-4. Figure C-3 shows the average
temperatures during each length soak period for the Plymouth Fury.
Bar graphs of average temperatures during transient cycles are included
in Appendix C as Figures C-4 and C-5, and the related tabulated data is
in Table C-5.
5. Sequential Bag Sampling
Emission rates and fuel consumption calculated from the eight
sequential CVS bag samples from the Plymouth Fury are listed in
Tables C-6 through C-16 in Appendix C. Generally, the masses measured
by the two procedures agreed within five percent. Also in Appendix C,

bar graphs of the eight bag sequences for each test condition, and bar

presented as Figures C-6 through C-18.
D. Car Number 4 - 1976 Chevrolet Vega
Following are the results of emission and fuel economy tests
using the 1976 Chevrolet Vega.
1. Length of Soak Period
Bar graphs of emission rates and fuel consumption during the
UDDS and MUDDS are shown in Figures 20 and 21, In Appendix D,
results of all tests, including emission rates and fuel consumption for
each bag sample, are tabulated and averages are listed for each por-
tion of replicate tests in Table D-2.
As can be seen in the Figures 20 and 21, HC emission rates in-
creased gradually with increases in soak period length of up to 16 hours,
but there was not a substantial difference between HC emission rates
following 16 hour and 36 hour soak periods. Although there was some
variation noticeable, the dominant trend was a gradual increase with
increasing soak period length. CO emission rates were approximately
equal for soak periods of 20 minutes to one hour, but were slightly
lower following a 10 minute soak. Following soak periods from two
hours to eight hours in length, the CO emission rates increased
sharply with longer soak periods. The CO following the 16 hour soak
period was approximately equal to that following the eight hour soak,
and following the 36 hour soak period the CO emission rate was sub-
stantially higher than following the eight and 16 hour soak periods.
NOX emission rates and fuel consumption increased slightly
with longer soak period length over the range tested with a few excep-
tions. NOX and fuel consumption following the 10 minute soak period
were slightly higher than following the 20 minute period. Fuel con-
sumption was not notably higher following the 36 hour soak period
than following the 16 hour soak period.
Emission rates and fuel consumption for the first 505 seconds
and the last 867 seconds of the UDDS following each length soak period
are shown inFiguresD-1 and D-2 in Appendix D. HC emission rates
during the first 505 seconds of the cycle were strongly related to soak
period length, increasing sharply following longer soak periods over
the entire range of soak periods examined. One exception to this trend

was data following the two hour soak period. Both tests at that condi-
tion agreed well, and all data was closely checked and should be con-
sidered valid. Some variation could be seen in HC emission rates in
the last 86? seconds of the cycle, but the variation was small and was
not clearly a function of soak period length.
CO emission rates in the first 505 seconds of the UDDS were
fairly constant following soak periods from 20 minutes to one hour in
length, but were slightly lower following the 10 minute soak period.
During this portion of the cycle, the CO emission rates increased with
soak period length in the two to eight hour range, were approximately
equal following soak periods of eight and 16 hours, but were considerably
higher following the 36 hour soak period. During the last 867 seconds
of the cycle, CO emission rates increased very slightly with longer
soak period over the entire range of soak periods tested.
NOX emission rates in the first 505 seconds of the UDDS in-
creased slightly with longer soak periods over the entire range of
lengths tested. In the last 867 seconds of the cycle, NOX emission
rates following soak periods up to four hours were approximately
equal, as they were following soak periods of eight hours and longer.
The NOX rates following the eight hour and longer soak periods were
slightly higher than those following the shorter soak periods. Fuel
consumption during both portions of the cycle followed a general
trend of increasing with longer soak period lengths, with the trend
being more noticeable in the first 505 second portion.
2. Comparison of Baseline and Modified Driving Cycles
Details of the statistical comparisons of emission rates and
fuel consumption during baseline and modified driving cycles are shown
in Table 12. For the highway cycles, the "t" test showed significant
differences between HC, and NOX emission rates. Average values
for the modified cycle were higher in each case, as shown in Figure
22. Actual values from each HFET and MHFET are listed in Table
D-3 in Appendix D.
In the case of the urban cycles, a "t" test showed significant
differences in NOX emission rates and fuel consumption between the
two cycles following the l6 hour soak periods, with lower NOX values
and fuel consumption during the modified cycle. For tests following
10 minute soak periods, a "t" test showed a significant difference in
HC and NOX emission rates and fuel consumption between the two
cycles, each value being lower for the modified cycle. A graphic
comparison of the urban cycles can be seen in Figures 20 and 21,
where results from, the modified cycle are plotted alongside the base-
line results.

3. Repeatability Between Replicate Tests
Table 13 contains emission rate and fuel consumption results
from all tests and the mean, standard deviation, and coefficient of vari-
ation for tests at each condition.
4. Temperature Measurement
In Appendix D the maximum, minimum, and average temperature
for each component are tabulated and the averages for replicate tests are
listed in Table D-4. Figure D-3 shows the average temperatures during
each length soak period. Also in Appendix D, as Figures D-4 and D-5,
are bar graphs of average temperatures during transient cycles following
specific length soak periods. The related data is listed in Table D-5 in
Appendix D.
5. Sequential Bag Sampling
The emission rates and fuel consumption calculated using the
eight sequential bag samples are listed in Appendix D as Tables D-6
through D-16. Also listed in each table is the difference between
masses measured with the eight bag samples and masses measured
with the 505 second sample bag. The masses measured using the
two procedures usually agreed within five percent. Also in Appendix
D, bar graphs of the eight bag sequences for each test condition,
and bar graphs comparing the eight bag sequences of the UDDS and
MUDDS are shown in Figures D-6 through D-18.
E. Car Number 5 1976 Honda Civic CVCC
The following is a description of the major findings from
testing the Honda Civic.
1 . Length of Soak Period
Emission rates and fuel consumption during the UDDS and MUDDS
are shown in bar graphs in Figures 23 and 24. In Appendix E results of
all tests, as well as emission rates and fuel consumption for each bag
sample, are tabulated and averages for each portion of replicate tests
are listed in Table E-2.
As shown in Figures 23 and 24, substantially lower HC and
CO valut-s were- measured on the Civic following soak period lengths
ol Iwo hours* -uid loss than following longer soak periods. Although
some variation was noticeable with soak periods of two hours and less,

the amount of variation was small relative to the average values. For
tests following soak periods of four hours and longer, CO and HC
emission rates increased sharply. NOX values measured following
soak periods of four hours and less did not change significantly with
variation in soak period length, even though the expanded scale in
Figure 2 accents the variation between tests. NOx values in tests
following eight hour and longer soak periods were noticeably higher
than those with shorter soak lengths. Fuel consumption was not
clearly affected by soak periods of 30 minutes and less, but increased
slightly with soak period lengths of one hour and longer.
Emission rates and fuel consumption for the first 505 seconds
and the last 867 seconds of the UDDS following each length soak period
are shown in Figures E-l and E-2 in Appendix E. During the first 505
seconds, HC and CO emission rates were not clearly a function of
soak period length with soak periods of two hours and less. Following
soak periods of four hours and longer, HC and CO emission rates
during the first 505 seconds increased sharply with longer soak
periods. HC and CO emissions for the last 86? seconds of the cycle
were not noticeably affected by soak periods of two hours and less,
but were affected by soak lengths of four hours and longer. With
the longer soak lengths, the last 867 second HC emission rates de-
creased slightly and CO emission rates increased slightly.
NOX emission rates during the first 505 seconds of the UDDS
were not affected by soak lengths of four hours and less, but were
higher following soak lengths of eight hours and longer. NOX emis-
sion rates during the last 867 seconds behaved like those of the first
505 seconds; fairly constant with four hour and shorter soak periods,
but increased slightly with soak lengths of eight hours and longer.
Fuel consumption in both portions of the cycle was unaffected by soak
lengths of 30 minutes and shorter, but increased slowly with longer
soak lengths.
2. Comparison of Baseline and Modified Driving Cycles
Details of the statistical comparisons of emission rates and fuel
consumption during baseline and modified driving cycles are shown in
Table 14. The "t" test showed significant differences between HC, CO,
and NOX emission rates and fuel consumption between the two highway
cycles. Average values for the modified cycle were higher in each
case, as shown in Figure 25. Actual values from each fuel economy
test are listed in Table E-3 in Appendix E.

FIGURE 25. COMPARISON OF EMISSION RATES AND
FUEL CONSUMPTION DURING HFET AND MODIFIED HFET
FOLLOWING 10 MINUTE SOAK
1976 Honda Civic CVCC
64
-------
In the case of the urban cycles, the "t" test showed significant
differences in HC, CO, and NOX emission rates and fuel consumption
between the two cycles following the 16 hour soak periods, with higher
emission values and fuel consumption during the modified cycle. A
"t" test showed significant differences in HC, CO, and NOX emission
rates between the two cycles following a 10 minute soak, with higher
CO and NOX emission rates in the modified cycle but higher HC emis-
sion rates in the UDDS. The test did not indicate a significant difference
in fuel consumption between the two cycles when preceded by a 10 minute
soak. A graphic comparison of the urban cycles can be seen in Figures
23 and 24, where results for the modified cycle are plotted alongside
baseline results.
3. Repeatability Between Replicate Tests
Table 15 contains the emission rate and fuel consumption re-
sults for all tests and the mean, standard deviation, and coefficient
of variation for tests at each condition.
4. Temperature Measurement
In Appendix E, in Table E-4, the maximum, minimum, and average
temperatures for each component are tabulated, and average temperatures
for replicate tests are listed. Average temperatures during each length
soak period for the Honda Civic are shown in Figure E-3. Bar graphs of
average temperatures during transient cycles following each length soak
period are also included in Appendix E as Figures E-4 and E-5, and the
related data is listed in Table E-5.
5. Sequential Sampling
Emission rates and fuel consumption calculated from the eight
sequential CVS bag samples are listed in Tables E-6 through E-16 in
Appendix E. The total mass of each gas measured during the eight bag
sequence of each test was compared to the mass of that gas measured
with the 505 second bag. This data is included in the tables of sequential
bag results. Bar graphs of the eight bag sequences for each test con-
dition, and bar graphs comparing the eight bag results of the UDDS and
MUDDS are also in Appendix E as Figures E-6 through E-18.
