This report summarizes the fuel economy data analysis performed on data from the report, A Study of Emissions from Heavy Duty Vehicles. The contract involved emission testing of 30 trucks. The truck stratification 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. Conclusions: diesel powered trucks peak fuel economy was attained at 30 mph; gasoline powered trucks peak fuel economy occurred at 40 mph for light load test conditions, 30 mph at heavier.
