Fuel Economy of Heavy Duty Vehicles
Introduction
This report summarizes the fuel economy data analysis performed on data
from Contract No. 68-03-2147, "A study of Emissions from Heavy Duty
Vehicles." This recently completed contract was conducted by Southwest
Research Institute.
The contract involved emission testing of 30 trucks. The truck strati-
fication included two axle single unit trucks, 3 axle single unit
trucks, and tractor trailer trucks. Eighteen gasoline and twelve diesel
engine powered trucks constituted the 30 tested. All measurements were
taken on a chassis dynamometer. From the emission measurements, fuel
consumption was calculated using the carbon balance technique. Although
both transient and steady state data were gathered, only the steady
state fuel consumption was analyzed in this effort.
The steady state testing involved running the trucks at various constant
speeds. Test speeds included 5, 10, 15, 20, 30, 40, and 55 mph. Also,
three different test weights were used for each truck: empty, half
load, and full load. (The individual test results are 'found in Appendix
A.)
Data Analysis
Initially, mile/gallon averages were calculated for all gasoline and all
diesel trucks. Figures 1 and 2 show the plotted averages. For the
diesel powered trucks tested, peak fuel economy (6.9 to 7.8 MPG) is
attained at approximately 30 mph, regardless of loading (empty, half, or
full load). For an empty diesel truck, fuel economy is decreased by
7.1% when traveling at 40 mph relative to the 30 mph maximum. At 55
mph fuel economy decreases by 14.8%. For a half loaded diesel truck,
fuel economy decreases 10.8% at 40 mph and 25.5% at 55 mph. Similarly, ;
the fully loaded diesel trucks experienced a fuel economy decrease of
14.0% at 40 mph and 31.5% at 55 mph.
The gasoline trucks tested also attained the best fuel economy (7.1 to
7.8 MPG) near a speed of 30 mph. However there seems to be less of a
decrease in fuel economy when going.from 30 mph to 40 mph, than with
diesel trucks. In fact, when empty, there is a slight increase (+1.8%)
in fuel economy at 40 mph. For half and full load conditions, fuel
economy decreases of 1.6% and 4.9% were experienced at 40 mph. At 55
mph decreases of 16.3%, 20.6%, and 23.0% were obtained for empty, half,
and full payload, respectively. ,
I
The next step in the data analysis was to group the trucks according to {
configuration. This was done by calculating the average fuel economies t
for the following truck categories: two axle-gasoline, two axle-diesel, i
three axle-gasoline, three axle-diesel, tractor trailer-gasoline, and [
tractor trailer-diesel. Figures 3 through 8 show the plots of the I
calculated fuel economies versus mph.
-------

The 2 axle-diesel, 3 axle-diesel, and tractor trailer-diesel trucks
achieve their best fuel economy at 30 mph. Table 1 summarizes fuel
economy decreases associated with increased speed and load for the
diesel powered trucks. The plots illustrate that the diesel trucks have
a very distinct fuel economy peak at 30 mph. Further, the percentages
in Table 1 demonstrate that there is a substantial decrease in fuel
economy when speeds exceed 30 mph.
Similary, Table 2 summarizes the fuel economy increases/decreases asso-
ciated with increased speed and load for the gasoline powered trucks.
Unlike the diesel trucks, the gasoline trucks have a less pronounced
fuel economy peak. The peak fuel economy is much less pronounced than
the diesel trucks, between 30 and 40 mph. In fact, at empty load, the
gasoline trucks achieve their best fuel economy at 40 mph. As the load
is increased to half and full, the peak fuel economy does occur at 30
mph, like the diesel powered trucks.
Discussion
As can be seen from the plots, vehicle speed has a significant effect on
fuel economy. As speed is increased, road load horsepower increases and
consequently fuel consumption increases. Rolling resistance, air resis-
tance, and road grade are the three primary items affecting road load
horsepower. For the data being analyzed, road grade was not a factor
since the chassis dynamometer simulates truck operation on a level road.
Only rolling resistance and air resistance are important. Rolling
resistance increases linearly with vehicle speed and air resistance
increases as the cube of vehicle speed. Therefore, it is not surprising
that fuel economy will decrease as speed is increased.
The fact that the gasoline powered trucks tested have a less pronounced
fuel economy peak as compared to the diesel powered trucks can probably
be attributed to the difference in performance maps of gasoline and
diesel engines. Also, where the location of a specific operating point
is on the performance map can drastically affect fuel consumption. Fuel ..:
consumption not only varies with engine torque (BMEP), but also with
engine speed. Torque requirements may stay constant, however, depending
upon what rpm the engine is operating at, the engine fuel consumption
can be influenced substantially.
For the steady state testing, SwRI attempted to select gear - axle
relationships which required an engine speed of approximately 2000 rpm
to obtain the necessary vehicle speed. In some cases this was impossible -
due to the vehicle speed required and the jgear spacing. Therefore,
frequent deviations above and below 2000 rpm occurred (refer to Appendix
A). As stated earlier, if a particular engine torque output is required
to maintain a constant mph value, various engine speeds can produce this
necessary torque output. However, fuel consumption can change dramatically
when engine rpm is varied while maintaining a constant torque (BMEP)

output. Figure 9, a typical performance map for a heavy duty diesel
engine, illustrates the effect of engine rpm on fuel consumption. For a
constant BMEP of 70 psi, fuel consumption can vary from .360 to more
than .400 Ibm/bhp-hr, depending upon engine rpm (refer to Fig. 9). This
clearly illustrates the effect of engine rpm on fuel consumption (fuel
economy). In summary, gear-axle ratios can substantially affect the
fuel consumption of an engine and ultimately the fuel economy of a
vehicle.
Another factor that should be considered is the limited scope of the
data itself. The data analyzed in this report, was collected entirely
during chassis dynamometer simulation of truck operation on a level
road. A very important factor influencing-the results of chassis dyna-
mometer testing is road load horsepower simulation. For heavy duty . |
trucks the road load horsepower simulation on the dynamometer is not I
defined nor understood very well.
!
l
In a cursory analysis, SwRI has demonstrated that the air resistance " \
portion of road load io accurately simulated for empty and lightly
loaded trucks, but is too high for heavily loaded trucks. Also, at low p
speeds the dynamometer power settings become quite small (refer to
Figure 10). This fact causes SwRI to conclude further that the varia-
bility of the test procedure probably exceeds the actual difference due
to a change in load. This is especially true at low speeds (less than
30 mph).
Chassis dynamometer testing of heavy duty trucks to date is not very
precise over the full range of vehicle speeds and loads because of the
road load simulation problem. For this reason, the fuel economy data ,:
used in this analysis may lack precision.
Summary and Conclusions \
i
In conclusion, the results as plotted in figures 1 through 8 demonstrate i
"Che effect of vehicle speed on truck fuel economy. For diesel powered \
trucks peak fuel economy was attained at 30 mph. For gasoline powered . - j.
trucks peak fuel economy occurred at 40 mph for light load test con-
ditions, while for heavier load test conditions peak fuel economy occurred
at 30 mph, like the diesels. In general, it is concluded that best fuel
economy for heavy duty trucks occurs* between 30 and 40 mph. The results ;
show the pronounced effect of speed on fuel economy: as speed is increased
above 30 to 40 mph, fuel economy decreases.
