I. INTRODUCTION
Current in-use emissions are typically estimated based on laboratory testing
because on-road test methods are cumbersome and costly. However, EPA has developed
an on-board emissions measurement system, called "ROVER," in an attempt to provide
a relatively simple and inexpensive means of determining in-use vehicle exhaust emissions
on the road. The objective of this project was to provide EPA with an independent
determination of how well ROVER measures in-use vehicle exhaust emissions, and how
those emissions relate to current exhaust emission standards. ROVER evaluations utilized
four diesel and four gasoline light heavy-duty trucks, and included:
• Collecting simultaneous exhaust emission and vehicle activity data from in-
use vehicles on a chassis dynamometer following CFR procedures. ROVER
emission measurements were compared to those using CFR-specified
analytical methods for correlation purposes.
• Simulating two specified driving cycles on a test track to correlate ROVER
data collected on the road and in the laboratory.
• Field testing ROVER on metropolitan San Antonio roadways over a sufficient
period of time and range of driving conditions to judge ROVER durability and
data quality.
In addition, the project evaluated the level of effort necessary to install, calibrate, and
maintain ROVER during vehicle evaluations, and identified areas where ROVER could be
improved.

II. TECHNICAL APPROACH
A. Test Fuel
All gasoline-fueled vehicles were tested using Federal certification grade EEE
unleaded gasoline (Table 1). This fuel was provided by Specified: Fuels, and was
identified by SwRI as Fuel EM-2818-F. Type 2 diesel (Table 2), provided by Phillips, was
utilized for diesel vehicle testing, and was identified by SwRI as Fuel EM-2731-F. A single
batch of each fuel was used for all testing.

Eight 1998 or newer model year standard production in-use light heavy-duty
vehicles were recruited for testing, four diesel-fueled and four gasoline-fueled vehicles
(Table 3). All vehicles were recruited through local leasing agencies, car dealers, and from
SwRI employees. When possible, the work assignment utilized vehicles in SwRI's
possession that were recruited for EPA Work Assignment 0-02, "Diesel Truck In-Use
Emission Test Program," as indicated in Table 3.
The first two vehicles to be tested were a 1998 model-year Dodge Ram 2500HD
Quad Cab pickup truck (Table 4) and a 1999 model-year Dodge Ram 2500HD Quad Cab
pickup truck (Table 5, Figure 1). Both vehicles were equipped with a Cummins 5.9L, 24-
valve, intercooled turbo-diesel engine producing 215 hp at 2700 rpm and 420 Ib-ft torque
at 1600 rpm. In addition, each vehicle was equipped with four-wheel drive and the SLT
equipment package.

C. Chassis Dynamometer
In the laboratory, vehicles were tested using a Horiba light-duty 48-inch diameter
single-roll chassis dynamometer. This dynamometer electrically simulates inertia weights
up to 12,000 lb over the FTP-75, and provides programmable road load simulation of up
to 125 hp continuous at 65 mph (300 hp momentary duty at 65 mph).
SwRI followed EPA-supplied methods for developing "a", "b", and "c" chassis
dynamometer coefficients, as given in Appendix A, using a Mears Model to calculate a
road load curve for each vehicle. This model required coastdown data from drive and non-
drive axles. Triplicate 65 to 15 mph coastdowns were conducted on each axle, and the
average results were used as input for the Mears Model in order to calculate dynamometer
"a," b," and "c" coefficients. The chassis dynamometer settings used during this test
program are given in Table 12.

D. Driving Cycles and Test Conditions
The ROVER system was evaluated over a variety of driving conditions in the
laboratory, on a test track, and on public roads. Details of driving cycles used and test
conditions encountered during this program are given below.
1. Laboratory Measurements
In the laboratory, exhaust emissions from each vehicle were evaluated
utilizing a chassis dynamometer over a duplicate sequence of transient test cycles, which
included the FTP, US06, NYCC, and High-Speed Freeway (FWY-HS) facility cycle. The
duration, distance, and average speed of these cycles are given in Table 13. The test cell
ambient temperature and humidity conditions conformed with those given in the Code of
Federal Regulations. The laboratory test sequence used for each vehicle is listed below
in Table 14.

Because the FWY-HS facility cycle starts and ends at speed, transition cycles were
needed to bring the vehicle to and from test speed. At the beginning of the cycle, the
vehicle was at idle. Sixty seconds were used to transition the test vehicle from idle to the
speed at the beginning of the FWY-HS. The driver accelerated the vehicle linearly for the
first portion of the transition. The driving trace immediately before the FWY-HS was
adjusted so that the vehicle would enter 10 seconds of operation to match the speed and
acceleration rate at the start of the test cycle. Similarly, at the end of the cycle, the
vehicle's speed and deceleration rate were matched for ten seconds prior to stopping the
vehicle. This method is shown schematically in Figure 5.

2. Track Simulation of Laboratory Driving Schedules
Following laboratory testing, the vehicle was prepared for testing at the track.
The NYCC and FWY-HS were simulated in duplicate on a level test track to approximate
the laboratory test conditions. As in the laboratory, transitions were used prior to and
following the FWY-HS tests. The General Tire test track, a 7-mile oval located outside
Uvalde, TX, was used for these evaluations. Test vehicles were hauled to the track on a
trailer (Figure 6). To ensure ROVER was fully warmed and stable, the system was plugged
into wall power overnight, and a deep discharge battery was used to power the system
during transit to the track. An attempt was made to simulate, as closely as possible, the
laboratory testing. The vehicle was preconditioned then immediately loaded onto a trailer.
The ROVER was installed in the vehicle, and the vehicle was maintained overnight at
typical soak temperatures. After being towed to the test track, the vehicle was unloaded
and testing was initiated. The track test sequence for each vehicle is listed below in
Table 15.

During track testing, an operator sitting in the driver's seat manipulated the vehicle
brake and accelerator to follow the specified driving cycles using a laptop drivers aid. A
second operator, sitting in the front passenger seat, steered the vehicle on the test track.
This method ensured that the on-track simulations approximated, as closely as possible,
the laboratory driving cycles.
On-track tests were conducted in the same order, at approximately the same time
of day, for all vehicles. All simulations were performed with vehicles in a fully warmed
condition, following an on-track simulation of the FTP. Vehicle accessories, including air
conditioning and radio, remained off during testing. An effort was made to test while the
ambient air temperature was between 68 and 86 °F and the ambient humidity was between
25 and 75 grains of water per pound of dry air. However, for the majority of the duration
of this work assignment, overnight lows in the San Antonio area were above 75 °F and
ambient humidity regularly exceeded 100 grains of water per pound of dry air. On-track
simulations were conducted as early in the daylight hours as possible; however, ambient
temperature and humidity conditions were routinely outside the requested limits by the end
of the last test.
On-Road Testing
To evaluate the ability of ROVER to successfully acquire data during a variety
of driving conditions, the system was evaluated on roads in the San Antonio area. The
road routes were specified by EPA as follows:
R START SA:
R_LOCAL_A_SA:
R_LOCAL_B_SA:
R ART A SA:
This initial route included a cold start followed by a 20 minute
drive of between 11 and 20 miles, with at least five miles on an
expressway, followed by an imitation of a "stop and shop"
situation, where the vehicle soaked fifteen minutes. Following
the soak was a hot start and an additional 30 minutes of
driving. All driving was done at the "speed of traffic." This
cycle loosely approximated the FTP.
60 minutes of stop-and-go driving through a central business
district. This cycle is similar in nature to the NYCC.
30 minutes of driving on "washboard-like" unpaved roads
60 minutes of low average speed (30 mph) but high
acceleration driving on an arterial collector type road. The
acceleration rates are similar to those of the US06.
R FWY A SA:
R FWY B SA:
60 minutes of continuous high-speed driving over hilly terrain
performed at the "speed of traffic"
60 minutes of continuous high-speed driving on flat terrain.
This cycle is similar in nature to the FWY-HS.

The test routes developed by SwRI are summarized in Table 16. All field work was
conducted during weekdays (Monday through Friday) with dry roadway conditions. When
ROVER operational problems did not interfere, road tests were typically started between
8:30 AM and 9:00 AM, conducted in the same order, and completed in a single day.
Vehicle air conditioners were operated during all tests; however, no radios were used.
E. Constant Volume Sampler System
During laboratory testing, SwRI constant volume sampler (CVS) system No. 8 was
used to dilute the exhaust and collect all necessary samples. This positive displacement
pump (PDP) CVS system includes an 18-inch diameter by 16-foot stainless steel dilution
tunnel for the collection of particulate samples, which were not required for this project.
This CVS was operated at a nominal flow rate of 700 scfm when testing the Dodge
vehicles, and 1,030 scfm when testing the Ford vehicles. The average temperature in the
dilution tunnel at the particulate sampling zone was 115°F during the standard FTP.
F. Laboratory Exhaust Emission Measurement
Dilute exhaust emissions were sampled and measured in a manner consistent with
EPA protocols for light-duty vehicle emission testing as given in the Code of Federal
Regulations. Proportional exhaust gas samples were collected in Tedlar bags for analysis
of carbon monoxide, and carbon dioxide. Total hydrocarbons and oxides of nitrogen were
measured continuously from the dilution tunnel and the results integrated. Exhaust
constituents were analyzed as specified below:
Compound Analysis Method
Total Hydrocarbon Heated Flame Ionization Detector
Carbon Monoxide Non-Dispersive Infrared Analysis
Carbon Dioxide Non-Dispersive Infrared Analysis
Oxides of Nitrogen Chemiluminescent Analysis
G. ROVER Exhaust Emission Measurements
The ROVER system was operated as specified during two training session with Mr.
Leo Breton of EPA. During the second training session, a series of ROVER operator check
sheets were developed to ensure proper operation of the system (Appendix B). For each
vehicle, a flowmeter was attached to the tailpipe to measure exhaust flow (Figures 7, 8,
and 9). A DGA1000 exhaust emissions analyzer, manufactured by Sun Instruments, was
used to continuously monitor THC, CO, NO, and C02 exhaust concentrations. An EPA-
supplied LabVIEW program running on a laptop computer was used for all data acquisition
and mass emission calculation. During laboratory evaluations, the DGA 100 and laptop
computer were set up next to the vehicle, and were powered by building electricity. For
track and field test, the complete system was installed in the vehicle (Figure 10) and
powered off the vehicle battery using a 12- volt DC to 120-volt AC power inverter.

H. Determination of Work
Dyno work was recorded for all test cycles using output from the Horiba chassis
dynamometer. For the determination of work using ROVER, the scan tool was used. One
of the signals provided by the scan tool was an estimation of engine torque. For the
Dodge, GM, and Ford gasoline vehicles, these estimates were based on "throttle position"
data provided by the scan tool as a percentage of full throttle. This information was used
as a surrogate for percent of full-load torque at any given rpm. Manufacturers' published
engine torque curves were split into either two or three regions and fit to polynomial
equations as a function of engine rpm.
f(engine rpm) - full-load torque
The engine rpm data provided by the scan tool were used as input into the torque curve
equations to determine full-load torque. The full-load torque was then multiplied by "throttle
position" as provided by the scan tool to determine net torque at any given point.
estimated net torque = full-load torque x percentage of full throttle
In the case of the diesel Ford vehicles, the scan tool provided estimated net engine torque
directly. Estimated torque and engine rpm were integrated and averaged over each test
cycle in order to determine horsepower:
cycle average hp = (average rpm x average torque) / 5,252
where 5,252 is a constant. Work was then determined as :
cycle average work = cycle average power x cycle time

III. ROVER OPERATIONAL EXPERIENCES
One objective of this project was to evaluate the level of effort necessary to install,
calibrate, operate, and maintain ROVER during vehicle emission evaluations. Prior to
testing, SwRI staff were trained on ROVER operation by Mr. Leo Breton and Mr. Dennis
Johnson of EPA during the period of June 28 through July 2, 1999. Following training,
testing of the 1998 and 1999 model year Dodge Ram 2500HD 4x4 Quad Cab Pickups was
initiated. Once during laboratory tests with these two vehicles the Sun DGA1000 exhaust
analyzer, which is part of the ROVER system, automatically rezeroed. The test during
which the autozero occurred was repeated without incident, and no other problems were
encountered during laboratory testing.
ROVER was then installed in each of the test vehicles for track testing. Twice while
testing the 1998 Dodge Ram, the DGA 1000 autozeroed. As in the lab, the tests during
which the two autozeros occurred were repeated, and no other problems were
encountered. During testing with the second vehicle (the 1999 Dodge Ram), problems
were encountered with the temperature probe on the Sun DGA 1000 analyzer. The probe
was replaced with a spare, but it did not work. The faulty operation of the replacement
temperature probe was confirmed using a spare DGA 1000. Leo Breton of EPA was able
to confirm by telephone that the replacement temperature probe was installed properly,
and as a result, an additional temperature probe was shipped to SwRI by overnight delivery
and installed.
The following morning, the DGA 1000 video display was no longer functioning
properly. A licensed Sun analyzer repair technician, from Equiserv, was called to service
the unit; however, he was not able to correct the problem. A replacement board, a repair
kit, and two spare temperature probes were ordered from Equiserv. These parts had to
be shipped from the UK, and took two weeks to arrive.
In the meantime, the ROVER system was installed in the 1999 Dodge Ram using
the spare Sun DGA 1000 analyzer (to be referred to from this point on as Unit #2), and the
vehicle was prepared for on-road testing. During the cold start portion of the
R_START_SA cycle, the analyzer autozeroed twice. By the end of the cold start segment
of this cycle, the NO and HC channels were reading zero, and the test was aborted.
After returning Unit #2 to the laboratory, the NO channel continued to read zero
during calibration checks on both low and high span bottles. An attempt was made to
recalibrate the NO channel, but it continued to read zero. In addition, the analyzer gave
a warning to replace the oxygen cell. The following day, the Equiserv technician replaced
the oxygen cell, and checked the leads on the NO cell on Unit #2. The analyzer was
recalibrated, but the NO response was sluggish. The NO cell was removed and replaced
with the cell from the original analyzer (Unit #1, which still had a bad video display). Unit
#2 was calibrated again, and appeared to be operating properly.
The ROVER system, using Unit #2, was reinstalled in the 1999 Dodge Ram, and
the vehicle was driven over the first portion of the R_START_SA on-road cycle to check
REPORT 08.02206.813
Page 20 of 71
-------
the system's functionality. The analyzer autozeroed three times during this checkout test.
Mr. Leo Breton was contacted for guidance. After confirming that the proper version of
software was loaded into Unit #2, a decision was made to wait for the backordered parts
for Unit #1 to arrive from the UK. At this time, replacement NO cells were also ordered for
both units. In addition, the 1999 Dodge Ram was released, with approval from the EPA
Work Assignment Manager, without successfully completing the track or on-road testing.
An unsuccessful attempt to repair the video display was made by the Equiserv
technician using the backordered parts that arrived from the UK. However, after all the
original parts were reinstalled, the video display began working, and continued to function
properly for as long as the unit was used. In addition, the Equiserv technician also brought
new NO and 02 cells. With the concurrence of Leo Breton of EPA, these new cells were
installed in both Unit #1 and Unit #2.
Unit #1 was calibrated and installed into the 1998 Dodge Ram. For three days, an
effort was made to complete the on-road testing. All on-road driving cycles were
conducted; however, the analyzer autozeroed repeatedly during testing. On the last of
these three days, the HC channel on the analyzer repeatedly failed a calibration check.
The following day, with the approval of EPA, testing with the 1998 Dodge Ram was
deemed complete, and the vehicle was released.
The following week, Mr. Leo Breton of the EPA visited SwRI to address the various
problems experienced with the two Sun DGA 1000 analyzers, and to provide additional
ROVER training. During his visit, Mr. Breton determined that the HC channel on Unit #1
could not be easily repaired and it was shipped back to EPA. Unit #1 was replaced with
another analyzer that Mr. Breton had brought with him, to be referred to as Unit #3. Also
at this time, Unit #2 was designated for diesel vehicle use only, and Unit #3 was
designated for gasoline vehicle use only.
The laboratory and track tests were successfully completed with two gasoline
vehicles, a 1999 Chevrolet 3500 Passenger Van and a Ford E-350 Passenger Van, using
Unit #3. However, as was the case with the other DGA 1000 analyzers, Unit #3 would
autozero during on-road tests. After a number of attempts to bypass the automatic zero
feature on the DGA 1000, and after consulting with the Work Assignment Manager, all
remaining vehicle on-road tests were conducted despite autozero events. A summary of
ROVER autozero events encountered during on-road testing is given in Table 17.
Another issue that arose during on-road testing concerned power consumption of
the ROVER system. A12V DC to 120V AC inverter was used to provide power to ROVER
from the battery of each test vehicle. This setup provided sufficient power to the system
while the vehicle was running. However, due to stability issues with the DGA 1000
analyzer, it is desirable to maintain power to the unit at all times (or else wait four hours for
the analyzer to warm up and stabilize). This became a problem during the R_START_SA
cycle, where a 15-minute vehicle soak was specified. This period was long enough to
deplete a vehicle battery enough to cause the DGA 1000 to shut down, which happened
on two occasions. Following these two events, and with the approval of the Work
Assignment Manager, the 15-minute soak was replaced with a 15-minute idle. In addition,
REPORT 08.02206.813
Page 21 of 71
-------
it was necessary to keep the vehicle idling during lunch breaks while on-road tests were
being conducted. Additionally, ROVER had to be plugged in to wall power at the lab
whenever the vehicle was not running.

General operation of ROVER was somewhat complicated due to the prototype
nature of the system. To address this issue, a set of check sheets specific to this Work
Assignment were created with input from both EPA and SwRI staff (Appendix B), which led
to more confident, repeatable operation of ROVER. It was somewhat difficult to operate
the ROVER program because the program window was too large to be completely
displayed on the laptop computer, requiring the operator to frequently scroll across the
screen during test setup.
Calibration of ROVER was relatively simple. However, the high span calibration gas
blend used for this program was a blend which had to be special ordered because it was
not a typical stock item when this program was initiated. The installation of ROVER in a
vehicle became fairly routine after gaining some experience with the system. However,
installing the exhaust flowmeter on the tailpipe of each vehicle required a number of hours
to fabricate hangers and holders to safely secure the flowmeter so neither it nor the vehicle
would be damaged during on-road testing.
REPORT 08.02208.813
Page 22 of 71
-------
As part of this project, the time needed to install, calibrate, maintain, and repair
ROVER was recorded for each individual vehicle evaluated. These results are presented
in Figure 11, and show that over the course of the project the time needed to operate and
maintain ROVER diminished as personnel became more familiar with its operation. Once
the system was functioning properly, the time needed for repairs was minimal. In addition,
test errors (primarily autozero events) were minimal following the initial problems
encountered with ROVER; however, while testing the sixth vehicle, a loss of power
occurred within the ROVER system which caused approximately four hours of down time.
By the end of the program, the time needed to install ROVER in and remove it from an
individual vehicle had been reduced from over fourteen hours to less than six hours. With
the early vehicles, much of the installation time was spent fabricating holders and brackets
that were utilized throughout the project. The other major effort in operating ROVER was
conducting calibrations. For the last three vehicles, when SwRI personnel had the most
familiarity with the system, approximately 5 hours of calibrations were needed to collect a
little over eight hours of data from a total of 18 individual tests per vehicle, or a little less
than 20 minutes per test. In general, by the end of the project the operation of ROVER
was routine and reliable.

IV. RESULTS AND DISCUSSION
All relevant vehicle specifications, test cell information, and emissions
measurements requested by EPA, including second-by-second mass emission rates, were
summarized in EPA-specified database files, and have been transmitted to EPA via e-mail.
Summaries of average emission results for all vehicles are given in Tables 18
through 25. Detailed results of laboratory tests as determined by CFR methods are given
in Appendices C through J.
One of the objectives of this project was to compare exhaust emissions collected
simultaneously following CFR procedures and using ROVER, from vehicles operating in
the laboratory on a chassis dynamometer. Comparisons of these simultaneous
measurements are given in Tables 26 through 33 for each of the in-use vehicles. These
data are presented graphically in Figures 12 through 16, along with linear regressions, for
both gasoline and diesel vehicles. Correlations exist for all exhaust constituents with
specific vehicles operating over specific driving cycles; however, the overall results are
highly variable. Therefore, results from gasoline and diesel vehicles were analyzed
separately. It should be noted that the CFR measurements are for total NOx, while the
ROVER measurements are for NO only. In addition, the CFR measurements are
presented both with and without the CFR-specified humidity correction. This presentation
of non-humidity corrected CFR data is necessary because the ROVER data are not
humidity corrected, and a direct comparison of uncorrected measurements was desired.
There appear to be strong correlations between the CFR and ROVER measurement
methods for determination of C02 and NOx (both corrected and uncorrected) for both the
gasoline and diesel vehicles, with r2 values of at least 0.94 in all four cases. These
correlations appear to be fuel independent. When the gasoline and diesel data are
combined, as shown in Figures 17 and 18, the r2 values are 0.99 and 0.94 for uncorrected
NOx and C02, respectively. Additionally, for measurements from gasoline vehicles there
appear to be correlations between the ROVER and CFR methods for THC (r2 = 0.92) and
CO (r2 = 0.98) measurements. There do not appear to be any correlations between the
CFR and ROVER data for HC and CO measurements from diesel vehicles.
Two of the laboratory driving cycles--the NYCC and the FWY-HS~were simulated
on a test track in an effort to correlate ROVER data collected on the road and in the lab.
A comparison of the average of duplicate emission measurements taken on the chassis
dynamometer and at the track is presented in Table 34. These data are also presented
graphically in Figures 19 through 22, and include all individual lab/track data pairs.
Although much of the data are highly variable, there appear to be correlations
between the lab and track for C02, with an r2 of 0.87 and a slope of 0.99 (Figure 23) when
the gasoline and diesel data are combined. In addition, there seems to be a correlation
between the lab and track measurements for NO from diesel vehicles. The correlation for
NO was not observed with gasoline vehicle measurements. This observation is interesting
because of the apparent correlation between the CFR and ROVER methods in the lab at

levels down to less than 0.1 g/mi. The correlation in lab and track C02 and NO
measurements, which both tend to be load dependant, seems to indicate that the vehicles
were being loaded in a somewhat similar fashion on the dyno and at the track. However,
possible factors contributing to any lack of correlation in other emission measurements
may include potential differences in vehicle operation on the dynamometer and at the
track, different environmental conditions, different power supplies for the measurement
equipment, and the impact of various degrees of vibration between the lab and the track
on the ROVER equipment.
Another objective of the project was to field test ROVER on metropolitan San
Antonio roadways to judge system durability and data quality. Except for the previously-
mentioned problems with the initial DGA 1000 analyzer, the occasional autozero events,
and the power consumption issues, ROVER seemed to be rugged and durable. The
quality of the emission measurements varied, as can be seen in Figures 24 through 27.
These figures present vehicle HC, CO, NO and C02 emission rates measured in the
laboratory, on the track, and on the road. The results are divided into four groups of
specified laboratory cycles and on-road cycles with similar characteristics as follows:
FTP and R_LOCAL_A_SA (Start)
FWY-HS, R_FWY_A_SA (Fwy A), and R_FWY_B_SA (Fwy B)
NYCC, R_LOCAL_A_SA (Local A), and R_LOCAL_B_SA (Local B)

The on-road HC and CO data appear to be highly variable in comparison to the specified
driving cycles with similar operational modes. Measured NO and C02 emission rates
appear to be somewhat more consistent between the specified driving cycles and on-road
cycles. However, differences in vehicle loading on the dynamometer, the track, and the
road; different environmental conditions during testing; the variability of traffic conditions
and driver reactions during on-road tests; and the differences in the test cycles themselves
are some of the many factors that need to be considered when attempting to compare the
on-road emissions measurements with those from the specified driving cycles. These
types of analyses can be highly subjective, and the reader is encouraged to draw his or her
own conclusions concerning quality of the on-road measurements.

V. RECOMMENDATIONS
ROVER shows promise in the on-road measurement of NO and C02, however, it
should be understood that the system that was evaluated was a prototype. There are
several areas that need further improvement, and they are listed as follows:
• The autozero issue with the Sun DGA 1000 analyzer needs to be addressed and
corrected. The analyzer seems to be affected by some side loading and low-
frequency vibration, which sometimes causes autozero events. These events take
about 60 seconds, during which ROVER is recording mass emission rates of 0 g/mi
for all channels. If the problem is inherent to the DGA 1000 analyzer and cannot
be solved, alternative exhaust emission analyzers should be investigated.
• Of the three DGA 1000 analyzers evaluated, two had difficulty maintaining
calibrations on separate occasions. Although one analyzer was serviced and
appeared to function properly for the remaining evaluations, it is questionable
whether the DGA 1000 is the proper analyzer for this type of on-road application.
It is suggested that alternative emission measurement instruments be investigated.
• Because the DGA 1000 requires up to four hours to reach stable operation, it is
necessary to keep ROVER operational during all on-road testing. However,
operation of the ROVER system requires more power than can be provided by a
vehicle's 12-volt battery. If necessary to turn off a vehicle for any reason, vehicle
battery voltage can easily drop below what is required by ROVER in as little as ten
to fifteen minutes, causing the DGA 1000 analyzer to shut down. Possible solutions
to this issue include finding ways to reduce the power consumption of ROVER, or
integrating a battery into the system that is capable of powering ROVER for 30 to
60 minutes.
• Although it is understood that ROVER is a prototype system, maintenance and
operation are fairly complicated. It would be much more convenient if the analytical,
data acquisition, and computational hardware could be integrated into a single,
compact package. This would also alleviate the potential for any number of
connectors, used for data acquisition and system control, to come unplugged. In
addition, the software user interface needs to be simplified, with more compact and
intuitive input and output displays.
• The current flowmeter is bulky, and difficult to install on vehicles. It would be useful
to investigate alternative exhaust flow measurement methods in order to find a more
compact device. In addition, it would be useful to devise a more standardized, non-
intrusive method of attaching ROVER's exhaust flowmeter to vehicle tailpipes.
• A more readily-available calibration gas mixture, available in a standard l/M-type
bottle, is desirable.
• NO should be humidity corrected according to CFR procedures.

VI. SUMMARY
An on-board emissions measurement system, called "ROVER," was developed by
EPA in an effort to provide a relatively simple and inexpensive means of determining in-use
vehicle exhaust emissions on the road. The objective of this project was to provide EPA
with an independent determination of how well ROVER measures in-use vehicle exhaust
emissions, and how those emissions relate to current exhaust emission standards. These
ROVER evaluations were conducted in the laboratory following CFR procedures, on the
test track over specified driving cycles, and on the road under a variety of real-word driving
situations. Testing utilized four diesel- and four gasoline-fueled 1998 and 1999 model-year
light heavy-duty trucks manufactured by Ford, Chrysler, and GM.
In the laboratory, vehicles were operated on a chassis dynamometer over a
duplicate sequence of transient test cycles, which included the FTP, US06, NYCC, and
High-Speed Freeway (FWY-HS) facility cycle. Gaseous exhaust emissions were measured
simultaneously following CFR procedures (THC, CO, NOx, and C02) and using ROVER
(THC, CO, NO, and C02). There appear to be strong correlations between the CFR and
ROVER measurement methods for determination of C02 and NOx for both the gasoline
and diesel vehicles. Additionally, for measurements from gasoline vehicles there appear
to be correlations between the ROVER and CFR methods for THC and CO measurements.
There do not appear to be any correlations between the CFR and ROVER data for HC and
CO measurements from diesel vehicles.
Two of the laboratory driving cycles-the NYCC and the FWY-HS-were simulated
on a test track in an effort to correlate ROVER data collected on the road and in the lab.
A comparison of emission measurements from tests conducted on the chassis
dynamometer and on the track showed an apparent correlation between the lab and track
for NO from diesel vehicles and for C02 from both gasoline and diesel vehicles.
ROVER was field tested on metropolitan San Antonio roadways to judge system
durability and data quality. As with the laboratory and track results, the on-road HC and
CO data appeared highly variable when compared to results from the specified driving
cycles with similar operational modes. Measured NO and C02 emission rates appeared
to be somewhat more consistent between the specified driving cycles and on-road cycles.
However, these types of analyses are highly subjective, and no firm conclusions could be
drawn concerning quality of the on-road measurements.
A number of operational deficiencies were encountered during evaluations. The
most notable concerned the tendency of the system to autozero during testing.
Additionally, the analyzers used in ROVER sometimes had difficulty maintaining
calibrations, and one of the analyzers failed during testing and could not be repaired. The
operation of ROVER required more power than could be provided by a typical vehicle's 12-
volt battery, causing system shutdown if the vehicle was turned off for short periods of time.
Additionally, ROVER was somewhat complicated to maintain and operate, and installation
on vehicles required the fabrication of custom brackets and hangers.

PROCEDURE FOR DEVELOPING A, B, & C DYNAMOMETER
COEFFICIENTS ON HDVS AT DIFFERENT LOADS
Definitions of Vehicle Weights
There appears to be some confusion from time to time about what terms are associated with different
vehicle weights. The following terminology is paraphrased from the CFR:
Vehicle Curb weight. a.k.a. Curb weight. (§ CFR86.082-2) means the weight of the vehicle with all fluids
at their nominal (full) capacity, including fuel. There is an exception for "incomplete" vehicles in the
above CFR quote. A chassis destined to become a camper is an example of such a vehicle. The
contractor shall follow the definition where it applies.
Gross vehicle weight (GVWR,§ CFR86.082-2) means the value specified by the manufacturer as the
maximum design loaded weight of a single vehicle. This the number usually found on the driver's side
door post.
The Equivalent test weight (ETW) for this work assignment is the weight of the as received vehicle with
its fuel tank filled to 40% capacity plus 300 pounds. The approximate relationship of ETW with vehicle
curb weight is as follows;
ETW = curb weight in lbs - (0.6 * (fuel capacity in gallons) * 7.05 lbs per gallon) + 300lbs
In the case of an "incomplete" vehicle the ETW can be calculated with the above formula using the
manufacturer's specified curb weight.
Dynamometer Coefficients for Prototype Vehicle at ETW
There is some uncertainty on the part of EPA on how best to obtain the "a", "b", and "c" dynamometer
coefficients used for this work assignment. The contractor should provide direction if they feel that the
instructions provided do not appear to be technically correct or are misleading. However, on the
prototype vehicle the contractor should perform the following calculations and procedures on the
prototype vehicle to help the WAM determine the best course of action.
If the certification track coast down coefficients at or near the ETW for the prototype are available, the
contractor shall use them for the testing at ETW. It they are not available, which is probably the case,
the contractor shall obtain from the "EPA l/M Look-Up Table" the Track Road-Load Horsepower at 50
(TRLHP 50mph) (The vehicle need not be identical, a 1996 Dodge 318 displacement 3/4 ton can be
assumed to be similar to a 1998 of the same type. Using the TRLHP and the ETW a 55-45 mph coast
down time in seconds (CDT^^) shall be estimated using the following formula;
CDT6MSmph = (0.06073*ETW)/TRLHP
50mph
Using the coast down time, the contractor shall perform the twin axil coast down procedure per the letter
by Mr. Gerald A. Esper (dated 8/29/95) to derive the coefficients for testing at ETW.
If suitable values are not found in the "EPA l/M Look-Up Table", use the procedures outlined in 40 CFR
§86.129-80 (c)(2)(iii), road load horse power determined by vehicle frontal area. The applicable
equation is for a single roll dynamometer is;
Hp 5omph = aA +P + (5.0 * 10- + 0.33*t)ETW
the values are as in the CFR and "a" shall always be 0.5 for the type vehicles in this test program.
REPORT 08.02206.813
A-1
-------
Using Hp 50mph calculate the CDT55^5mph as above;
CDT5M5mph = (0.06073*ETW)Hp 50mph
Using the coast down time, the contractor shall perform the twin axil coast down procedure per the letter
by Mr. Gerald A. Esper (dated 8/29/95) to derive the coefficients for testing at ETW.
Upon obtaining the dynamometer coefficients, the contractor shall perform 55 to 45 mph coast downs
with the vehicle fully warmed. The contractor shall do and report six coast down times for the ETW
setting.
The coefficients at ETW shall be calculated using the procedures described in section 7.4 "TOTALLY
CALCULATED LOAD COEFFICIENTS" in the document "Comparison of Road Load Estimations", W.
G. mears 4/1/495, revised 4/22/95 and 5/24/95, page 7.
Upon obtaining the dynamometer coefficients, the contractor shall perform 55 to 45 mph coast downs
with the vehicle fully warmed. The contractor shall do and report six coast down times for the ETW
setting.
At the other loads that are to be tested in this program the best technique to adjust the dynamometer
coefficients shall be judged through the following study to be performed on prototype vehicle.
The first method is to use the same coefficients determined at ETW and add inertia simulation to the
dynamometer to match the new test weight. Upon doing this the contractor shall perform six 55 to 45
mph coast downs with the vehicle fully warmed.
The second method is to calculate a new target coast down time at the new test weight, lets say GVWR
for example, using the following formula
CDT^ = (0.06073*GVWR)/TRLHP ^
Using the coast down time, the contractor shall perform the twin axil coast down procedure.
Upon obtaining the dynamometer coefficients, the contractor shall perform six 55 to 45 mph coast
downs with the vehicle fully warmed between 55 to 45 mph.
A third method is like the second except that the test vehicle shall be loaded with ballast such that the
vehicle weighs the same as the test weight in question (GVWR in the example).
All data and calculations shall be forwarded to the WAM for evaluation before beginning any emission
testing.
