No significant differences exist between the baseline and test MPG for any of the three trucks. • No significant differences exist for the composite data among all three trucks. • No significant trends exist regarding fuel efficiency as a function of temperature or duration of study, with the possible exception of the ULSD truck where the slope of the trend-line for MPG vs time (in weeks) was significantly different than zero.
Engine load as a function of temperature. Engine load generally increases as the temperature increases. No major differences are evident among the three trucks.
Average Load Average Temperature Overlapping standard deviations suggest no real differences among the three trucks. The data suggests a trend where temperature and load are negatively correlated.
Engine load as a function of fuel efficiency. No correlation appears to exist between engine load and fuel efficiency in any of the three trucks.
Average Load Average Fuel Efficiency Overlapping standard deviations suggest no real differences among the three trucks. *Values represent combined baseline and test data.
Engine load as a function of exhaust pressure. Exhaust pressure generally increases as the engine load increases. No differences appear to exist among the three trucks.
Average Load Average Exhaust Pressure Overlapping standard deviations suggest no real differences among the three trucks. The data suggest a trend where load and exhaust pressure are positively correlated.
ULSD Fuel Quality *Average of tests with quantifiable results. 13 oxidation stability test results were greater than 16 hours.
