ABSTRACT
Analyses using real-time dynamometer test emissions data from 13 passenger cars
were performed in a study to examine variations in emissions during different speeds, or
modes of travel. The resulting data provided a means for separately identifying idle,
cruise, acceleration, and deceleration emissions for examining how emissions differ by
vehicle speed during cruise mode.
To select a set of vehicles for the study, the hydrocarbon-time relationship was
established for several vehicles operating on summer-grade base fuel. Federal Test
Procedure (FTP) results were then produced and examined to identify normal emitters
{clean vehicles). After these vehicles were selected, an intensive analysis of their second-
by-second emission characteristics was conducted.
The FTP runs for cold start, hot start, and hot stabilized emissions (Bags 1, 2, and
3 of the FTP) were performed for each of the four driving cycles — acceleration,
deceleration, idling, and cruise — and the fraction of overall emissions contributed by
each mode was computed for the warmed-up portion of the driving cycle. A protocol was
then developed for review of the FTP real-time data.
The study results showed significant emissions differences related to travel mode;
(1) cruise mode emissions are invariant with speed when expressed on a grams-per-
second basis; (2) emissions resulting from acceleration from a stop to cruise speed are
similar to those resulting from acceleration from cruise speed to a higher speed; (3)
acceleration emissions were the highest of all the modes; and (4) cruise emissions are
very similar to idle emissions.

SECTION 1
INTRODUCTION
BACKGROUND
This report covers analysis performed using real-time dynamometer test emissions
data from 13 passenger cars, A special focus of the analysis was to examine variations in
emissions during different speeds, or modes of travel. The data sets used in this project
were extracted from the oxygenated fuels (Stump, Knapp, and Ray, 1990a and 1990b)
and the high temperature vehicle emission studies (Stump, Knapp, mid Ray, 1992a and
1992b) conducted by the Mobile Sources Emissions Research Branch (MSERB), U.S.
Environmental Protection Agency (EPA). These studies measured emissions on 17 1986
to 1990 model year vehicles with accumulated mileages ranging from 17,000 to 55,000
miles.
A major impetus for this project was to investigate information developed in a
paper written by Leonard Seitz (Seitz, 1989), which examined some of the differences
between methods used by EPA and the California Air Resources Board (CARB) for
estimating motor vehicle emissions. The paper suggests that, by expressing emission
rates in per hour or per minute units rather than per mile, the speed factor issue may be
much simpler than the way it was being handled in EPA models. His graphs even
suggest that average trip emissions may not be a function of speed at all. If this
1
-------
observation by Seitz could be substantiated over a wide range of speeds (e.g., 0 to 60
mph), then that entire range could be handled as one mode in a modal model.
OBJECTIVE
Modal emissions data, such as the data sets examined in this study, provide a
means for separately identifying idle, cruise, acceleration, and deceleration emissions.
These data also provide the opportunity to study how emissions differ by vehicle speed
during cruise mode, which is important when trying to determine ways in which motor
vehicle emissions modeling can be made simpler, such as assuming that cruise emissions
per time unit are constant with speed.
A recommendation was made at two EPA-sponsored highway vehicle workshops
(Wilson and Ripberger, 1991) that, though modal models have historically been viewed
as tools for mieroscale, highway impact, or signalized intersection-type analyses, they
could potentially be used much more broadly. One of the possible reasons why the
Southern California Air Quality Study (SCAQS) Tunnel Study (Ingalls, Smith, and
Kirksey, 1989) measurements were so difficult to correlate with the EMFAC7 (CARB,
1986) model estimates was that it was not possible to simulate the exact operating
conditions on the roadway in question using EMFAC7. A modal model should be able to
more accurately simulate the emissions for link-specific analyses. In addition, as mobile
source emission inventory techniques get more sophisticated, a modal model could
potentially be used to better estimate emissions throughout an urban area using many
separate modal emissions analyses. This could be termed the link prototype approach,
because a number of prototype traffic situations could be modeled and then matched with
links in the modeling network to estimate their emissions.
2
-------
Ripberger and Markey (1991) also discuss the potential of modal testing and
modal simulation models for use as key parts of EPA's research plan for developing a
basic emissions estimation model, based in part on the fact that vehicle emissions are not
constant over a range of operating conditions. Further, modal testing would need to
cover the range of modes experienced by in-use vehicles: idle, cruise (over the entire
speed range), acceleration, and deceleration.
Note that Federal Test Procedure (FTP) measurements are typically made in
phases or Bags, with the results being expressed as averages over the measurement
period. The FTP begins with a cold start, and Bag 1 represents the first 505 seconds of
vehicle operation. Seconds 506 through 1372 of the FTP are known as Bag 2 and
represent the hot stabilized phase of the cycle. Following Bag 2 is a 10-minute engine-
off period. Then, there is a hot start and the vehicle is operated using the same speed-time
trace as in Bag 1. This phase is known as Bag 3.
REPORT ORGANIZATION
The analysis in this report is based on work that was performed in two phases.
Phase 1, covered in Sections 2 and 3 of this report, focused on examining the
hydrocarbon-time relationship for several vehicles operating on summer-grade base fuel.
Overall FTP results were produced and examined to identify four or five vehicles that had
emissions that were considered normal (or clean); these were used for further analysis.
For this subset of clean vehicles, hydrocarbon (HC) time traces were developed for the
long arterial road cruise section, also known as Hill 11, of the FTP.
Phase 2 of this study, covered in Sections 4 and 5 of this report, involved
intensive analysis of the second-by-second emission characteristics of the selected clean
3
-------
vehicle models. First, the reproducibility of emission patterns was examined for particular
acceleration, deceleration, and cruise modes. Second, the fraction of overall emissions
contributed by acceleration, deceleration, idling, and cruise modes was computed for the
warmed-up portion of the driving cycle for these modes. Finally, a protocol was
developed for review of FTP real-time data.

-------
SECTION 2
PHASE 1: STUDY METHODS
The data for the analyses in this report came from two prior EPA studies, the
oxygenated fuel studies (Stump, Knapp, and Ray, 1990a and 1990b) and the high
temperature studies (Stump, Knapp, and Ray, 1992a and 1992b). The oxygenated fuel
studies were conducted to determine the effect of fuels containing alcohols and ethers on
vehicle tailpipe and evaporative emissions. The studies also were conducted with
commercial summer grade gasoline as a comparative fuel. The oxygenated fuels were
expected to reduce tailpipe hydrocarbon (HC) and carbon monoxide (CO) emissions by
leaning out the air/fuel mixture. Also, the oxygenates enhance octane rating and
compensate for the elimination of lead, an octane booster.
The high temperature studies (from where the rest of the data for these analyses
were obtained) were conducted to determine the emission contribution of motor vehicles
to the ambient pollution at elevated summer temperatures. The National Ambient Air
Quality Standard for ozone (O3), as established by EPA, of 0.12 ppm (by volume, 1-hour
average) is exceeded most often during the summer months. Motor vehicles make a
significant contribution of HCs and oxides of nitrogen (NOx) emissions, which are the
primary precursors in the atmospheric photochemical processes resulting in the formation
°f O3.
5
-------
During these studies, tailpipe and hot soak emissions were determined at
temperatures of 40,75,90, and 105°F, Diurnal evaporative emissions were determined
at fuel tank temperature ramps of40-64,60-84,72-96, and 84-108°F. The vehicles were
chosen based on sales and not all of the vehicles were tested at all test temperatures or
with all test fuels. The real-time regulated emissions and fuel economy data were
acquired from the data base generated by these vehicle studies.
Table 2-1 lists the vehicles for which emission measurements were used in this
study. The vehicle IDs listed in this table are also used in other tables in this report as a
shorthand way of identifying vehicles. [Note: Because vehicle C0174G only had two
FTP runs, it was not included in the data set that was analyzed for this study.]

SECTION 3
PHASE 1: STUDY RESULTS
FEDERAL TEST PROCEDURE RESULTS
Vehicles C0322G and C0665W were the only vehicles operated on oxygenated,
as well as the summer-grade, fuel, and only the summer-grade fuel data were used in this
analysis. All of the other vehicles were operated only on the summer-grade fuel. The
first set of tables in this chapter shows the bag-specific results for each of the vehicle/run
combinations. These results were produced using a Lotus 1-2-3 macro that was
originally written by Richard Snow of ManTech.
While these tables are useful by themselves for determining the emission
characteristics of the vehicles tested, in this study they were used primarily to identify
normal emitters, where a normal emitter emits less than twice the applicable standard.
The applicable standards for the model year vehicles tested are; 0.41 g/mi HC; 3.4 g/mi
CO; and 1.0 g/mi NOx.
Table 3-1 lists the weighted Bag 1, Bag 2, and Bag 3 emissions for the 80 FTP
runs performed using summer-grade gasoline. From this data set, 47 runs were identified
as being normal emitters. It is interesting to note that of the 13 vehicles tested, 7 were
always normal emitters, only 1 was never a normal emitter, and the rest were normal
emitters on some runs and not on others. It is likely that some of the variation in
emissions between runs is caused by the temperature differences among tests.

-------
The FTP results were then used to select two of the cleaner cars to examine
further: vehicle S0756B and vehicle LS612B. Initial analyses of the test data from these
two cars are presented in the form of plots of HC emissions in parts per million (ppm)
versus vehicle speed (mph) as shown in Figures 3-1 through 3-14. The plots all begin
767 seconds into the cycle, which means that they are well into the hot stabilized mode
(no cold start effects) and include Hill 11. The second-by-second data for six runs are
displayed for each of the two vehicles. Composite figures for each vehicle, titled All HC
Rims, are presented in Figure 3-7 (for vehicle S0756B) and Figure 3-14 (for vehicle
LS612B).
One observation that can be made from these figures is that the spikes in HC
emissions relate to changes in speed (i.e., accelerations produce the highest emissions,
but cruise did not produce changes). It is also notable that accelerations from a cruise
speed to a higher speed appear to be as important as accelerations from a stop in
producing high HC emission values. Some runs show these phenomena more clearly than
others, however. Vehicle S0756B shows consistent emission traces from ran to run, with
the possible exception of run 31016, which has somewhat lower HC emissions during the
non-spike periods. Emissions from vehicle LS612B appear to be more variable.

SECTION 4
PHASE 2; METHODOLOGY
INTRODUCTION
The analyses performed for this effort were divided into three
distinct parts:
1. Standard FTP analysis for the cold start, hot start,
and hot stabilized phases (Bags 1, 2, and 3) of the
FTP;
2. Modal analyses of the four driving modes within
Bags 2 and 3; and
3. Statistical analysis of second-by-second HC
emissions.
The real-time (by second) FTP data were delivered to Pechan in
over 200 ASCII text files, along with the FTP reduction Lotus 1-2-3
macro spreadsheet, which reduced the data into the FTP time phases.
The analyses performed focused on a subset of 12 vehicles, representing
76 FTP runs, selected for data robustness (at least four FTP runs each),
fuel (summer-grade gasoline only), and emissions behavior (showing
average emissions in grams per mile of not more than twice the
applicable Federal emission standard of any regulated pollutant).

-------
One of the first steps performed was to translate the Lotus 1-2-3 spreadsheet
macro into dBASE HI Plus format, to allow ease of program modification, program
documentation, and data base development without the disadvantage of memory
limitations which are often experienced on spreadsheet-type models. The two model
versions — the original spreadsheet and the equivalent dBASE code — were used
interchangeably in the analysis. The dBASE version source code is shown in Appendix
A
Modal analysis by FTP phase for Bags 1,2, and 3 were performed using the
original FTP spreadsheet, augmented with a vector of mode flags added for each mode
(idle, acceleration, cruise, and deceleration) for each of the 2,477 seconds of the FTP, and
separate aggregation calculations were constructed. Modes were taken from the Urban
Dynamometer Driving Schedule Mode Table (Gabele and Colotta, 1981), as shown in
Figure 4-1, and were entered into the spreadsheet using Lotus macros.
Statistical analyses of HC emissions versus independent variables such as speed
and acceleration were performed using standard linear regression and analysis of variance
methods of the Statistical Analysis System (SAS) PC software package. This
investigation included trial regressions of measured and lagged speed and acceleration for
both HC emissions and changes in HC emissions. All of this analysis was performed on
the raw exhaust emissions, without calculating dilution effects or transforming to grams
per mile (the HOTFID variable is the variable on the right in the HC emissions regression
analysis in Section 5).
The following section discusses the mathematical relationships used for each of
these three parts of the analysis.
29
-------
MATHEMATICAL RELATIONSHIPS
Standard Federal Test Procedure Analysis
The spreadsheet model delivered to Pechan contained the FTP equations from 40
CFR §86.144-78 used for calculating grams per mile from exhaust analyzer emissions
data. The relevant equations from that document are provided in Appendix B. While
highly detailed in some of the adjustment formulae, the essential calculations are shown
in equations 1 through 4 below, using HC as an example:
HC
HCmass = Vmix * Densityuc * = [Hydrocarbon emissions in (1)
In this equation, an HC density of 16.33 grains per cubic feet (g/ft^) is assumed, and
HCconc is diluted hydrocarbon concentration in parts per million, as calculated below.

where:
HCe = HC concentration of the diluent exhaust sample as measured
(ppm)
HCd = HC concentration of the diluent (background) air (ppm)
DF = Dilution Factor
C02e = CO2 concentration of diluent exhaust sample (ppm)
COe = CO concentration of dilution corrected for water vapor and
CD 2 extraction (ppm)
VQ = Volume per revolution of constant volume sampler (CVS)

N = Number of revolutions of CVS pump during sample period
P5 = Barometric pressure (mmHg)
P4 = Barometric pressure below atmospheric measured at inlet to
CVS pump during idle (mmHg)
Tp = Average temperature of diluent exhaust entering the CVS
pump during test (in degrees Rankine = degrees F + 460) [The
528 in the numerator of equation (4) is 68°F + 460, or
"standard temperature."]
A typical output for one run of the FTP analysis program is shown in Table 4-1.
The calculations involved follow the equations listed above, except for Vmjx,

which was calculated using constants calibrated to the equipment and time
of the phase (Bag). For an example of the calculations, consider the 0.212
g/mi value for Bag 2 HC emissions in Table 4-1. This value was calculated
with the FTP equations above using the values that follow.
Tp = 95.125T
Pb = 757.4 mmHg
HCe = 11.985 ppin (measured exhaust gas, the HOTFID
variable)
Miles = 3.874 (Bag 2)
COe = 24.17 ppm
C02e = 0.429 ppm
DF = 13.4 / [0.429 + 0.0001 * (11.985 + 24.17)] =
30.94
Vmix = 2.3737 * (Pb - 35.5) = 8932.6 ft^
Hconc = 11.985 - 6.563 * (1-1 / 30.94)
= 5.634 ppm
HCmass = 5.634 * 8932.6 * 16.33 / 1000000
= 0.8218 grams (for entire Bag 2)
HCgPm = 0.8218 / 3.874
= 0.212 g/mi
33
-------
Modal Analysis of the Federal Test Procedure Data
In a separate analysis, HC emissions in grains were calculated for each of the
modes of the FTP runs for the 76 FTP cases selected. In modal analysis, the concept of
grams per mile is meaningless, since speed or miles traveled per second is a denominator;
thus, grams per mile would be infinite in idle mode. To overcome this problem, a
normalized measure of relative emissions across driving modes was developed, as
described below.
Figures 5-1 through 5-3 (Section 5) present a measure of the rate of HC emissions
by driving mode (idle, acceleration, cruise, and deceleration) for Bags 1,2, and 3 of the
FTP dynamometer test. These figures are based on the sample FTP runs.
The numbers underlying the figures represent normalized measures of relative
emissions between the modes and Bags. In this context, normalized means that the
measure is dimensionless, gives no favor to any subset number (e.g., clean versus dirty
vehicles) of FTP runs among the samples, and is intended to serve only as a rough
measure of the relative rate of HC emissions within a Bag among the four driving modes.
The values shown in the tables in Section 5 represent average normalized HC
emission rates identified by mode, within a specified FTP phase (Bag), which are
estimated as follows:
[HC exhaust analyzer data, ppm, Bag B, vehicle v, run r, (5)
mode m, time t seconds.] (Note: this is the raw data for the
HOTFID monitor of the FTP.)
(6)
[Instantaneous HC emissions in g/sec, mode m. Bag B, vehicle v, run r.]
34
-------
Note that the constant 0.0141795 in equation 6 was calculated from constants
delivered to Pechan in the Lotus 1-2-3 spreadsheet, and is related to the specific CVS
equipment used in the analysis and temperature. The constant 0.0141795 = 7.156803/505
gives an equivalent instantaneous constant for calculating the real-time value.

and 156,223, 303, and 190 seconds for the corresponding
Bag 2 (hot stabilized phase) driving modes.

Statistical Analysis of Hydrocarbon Emissions
The statistical analysis performed for this project was done using the unadjusted
HOTFID speed and mode values in the original raw data files. Thus, the HOTFID output
was used as a surrogate measure of adjusted HC emissions.
Standard analysis of variance and linear regression analysis was performed on the
data in the SAS/PC statistical package. Data transformations were simply lags of 1 to 3
seconds and delta changes between observations. Change in speed between consecutive
observations was defined as acceleration.
36
-------
While several data transformations (models) were attempted (such as log-linear
regression), it was soon found that the underlying data showed relatively weak
dependency; such transformations produced no discernable improvement in R-squared or
other measures of goodness of fit over straightforward, right-hand-side variables such as
actual or lagged speed or acceleration.
37
-------
SECTION 5
PHASE 2: MODAL RESULTS
HYDROCARBON EMISSIONS BY MODE
Using the techniques described in Section 4, HC emissions were analyzed for
each of the vehicle FTP tests for the 12 vehicles studied. Table 5-1 provides an analysis
of the Bag I (cold start phase) HC emissions data; these are separated into 94 seconds of
idle, 103 seconds of acceleration, 223 seconds of cruise, and 85 seconds of deceleration.
The second column in Table 5-1 shows the total grams of HC emitted during Bag
1. This value is expressed as a grams-per-mile emission rate in the third column, based
on the assumption that a vehicle travels the equivalent of 3.6 miles during the Bag 1 test.
Modal emissions (in grams) are shown in columns four through seven of the table, with
second-by-second emission values being sorted among modes according to the schemes
described in the previous section. Columns 8 through 11 show the percentages of total
Bag 1 emissions that were observed in each mode. The last four columns show modal
emissions expressed in the form of mass per unit of time (milligrams per second, or
mg/sec).

SPEED VERSUS EMISSIONS
This section investigates the hypothesis that there is only a slight correlation
between instantaneous recorded vehicle speed (in miles per hour) and HC emissions rate
(in grams per mile). The HC emission rate is calculated on a per-second basis for
well-behaved gasoline vehicles operating in the cruise portions of the FTP cycle. Three
FTP runs per vehicle were chosen, resulting in a total of 18 FTP runs.
Only Bag 2 (seconds 506 to 1372) and Bag 3 (seconds 1973 to 2477) were used
for this analysis to eliminate the potential cold start biases of Bag 1. Bag 3 is of interest
because it contains highway speeds in excess of 50 mph. HC emissions in grams per
second were calculated using a number calculated from the data base for each FTP
nm, representing cubic feet of total diluted mix passing per second (e.g., 10.3).
Mathematically, the emissions rate (in grams per mile) for a total FTP run or a
specific time/mode slice (e.g., cruise mode in Bags 2 and 3) is not the average of the per-
second grams-per-mile rates. (The average of several fractions is almost never the
average of the numerators divided by the average of the denominators.) In addition, low
speed seconds in the FTP will tend to augment errors due to their small denominators.
Since the cruise modes in Bag 2 were at slower speeds than in Bag 3, there tended to be
few high HC emission rate outliers in Bag 2, possibly because of the introduction of
random errors or HC monitor lags not otherwise accounted for. (This was probably the
primary cause of the very slight negative correlation that was found between
instantaneous HC rate and speed.)
As Tables 5-4 and 5-5 show, there was no discernable correlation between speed
and the per-second HC grams-per-mile rate. The Pearson correlation coefficients, -0.12
to -0.25 for the six vehicles, are not sufficient to indicate that a more sophisticated model
could be developed to test the hypothesis.

FTP RUN STATISTICAL ANALYSIS
This section describes statistical analysis performed for 76 FTP runs covering 12
gasoline-fueled vehicles. The purpose of the analysis was to see if there appeared to be a
reasonable model to use for estimating HOTFID (the actual HC concentration variable)
using speed, acceleration (taken to be the first difference of speed), or lagged
representations thereof, A delta HOTFID dependent variable was also developed,
although it did not show much improvement in correlation.
The highest simple correlation observed was between the lagged (2-second)
acceleration, the variable L2ACC in the tables, and HOTFID. This correlation is not
consistent across vehicles, however. Table 5-6 shows HOTFID versus L2ACC
correlations of +0.56 for the 1988 Buick LeSabre, but only +0.09 for the 1987 Crown
Victoria. Nevertheless, 8 out of the 12 vehicles have correlation coefficients greater than
0.3, showing that there is a relationship between the variables (though probably a weak
one). Table 5-7 summarizes the average correlation of HOTFID versus L2ACC for each
vehicle.
Figure 5-1 shows the L2ACC and HOTFID variable time series for the best run of
the 1988 Buick LeSabre (LS612B). For this vehicle, as well as for most of the well-
behaved vehicles, the graphs of HOTFID and L2ACC show spikes in the first few
seconds of positive acceleration, though they become more erratic and less prominent
during other times (modes).

CRUISE MODE EMISSIONS ANALYSIS
Further investigations of the relationship between speed and HC emissions were
made for the six normal emitters in the data set. This analysis was restricted to cruise
mode emissions to allow full comparison of emission results, which are expressed either
on a grams-per-mile or grams-per-second basis.
Figure 5-2 plots the instantaneous HC emission rate (on a per-mile basis) versus
vehicle speed during cruise mode for vehicle C0322G (a GM Corsica). Most of the
higher emission values were observed at low speeds, though the data seem to support the
hypothesis that cruise mode emissions do not change much as speed increases or
decreases. Figures 5-3 and 5-4 show similar plots for vehicles C0665W and S0756B
respectively. These data tend to support the conclusion that cruise mode emissions are
invariant with speed.

SECTION 6
SUMMARY OF FINDINGS
Federal Test Procedure-measured cruise mode emissions are invariant with speed
when expressed on a grams-per-second basis. Accelerations produce the highest
emissions. Accelerations from a cruise speed to a higher speed appear to be as important
as accelerations from a stop in producing high HC emission values. In general, emission
rates for Bag 3 (in g/sec) are highest during acceleration and lowest during deceleration.
Cruise emission rates appear to be nearly the same as those during the idle mode.

* data is real-time, organized by second into five phases:
* bagO: 1-124 seconds 124 total
* bagl: 1-505 seconds (505 total) acc,crz,dec,idl
* bag2: 506-1377 seconds (872 total) acc,crz,dec,idl
* bkgd: 1378-1977 seconds (600 total) "background" (engine off)
* bag3: 1978-2482 seconds (505 total) acc,crz,dec,idl
* the first six rows of the data bases are labels and coefficients
* data begins in row seven, so offset record no's for phases are:
* bagO: 7-130 (124 seconds)
* bagl: 7-511 seconds (505)
bag2: 512-1383 seconds (872)
* bkgd: 1384-1983 seconds (600) total background
* bkusd: 1443-1922 seconds (480) background used
* bag3: 1984-2488 seconds (505)
* the files contain odd numbers of rows, like 2488, 2492, or 2493

The report gives results of analyses using real-time dynamometer test
emissions data from 13 passenger cars to examine variations in emissions during
different speeds or modes of travel. The resulting data provided a way to separately
identify idle, cruise, acceleration, and deceleration emissions for examining how
emissions differ by vehicle speed during the cruise mode. To select a set of vehicles
for the study, the hydrocarbon (HC)/time relationship was established for several
vehicles operating on summer-grade base fuel. Federal Test Procedure (FTP) re-
sults were then produced and examined to identify normal emitters (clean vehicles).
After these vehicles were selected, their second-by-second emission characteris-
tics were analyzed. The FTP runs for cold start, hot start, and hot stabilized emis-
sions (Bags 1, 2, and 3 of the FTP) were performed for each of the four driving cy-
cles— acceleration, deceleration, idling, and cruise—and the fraction of overall
emissions contributed by each mode was computed for the warmed-up portion of the
driving cycle. A protocol was then developed for review of the FTP real-time data.
Study results showed significant emissions differences relating to the travel mode.
