Exhaust emissions and fuel consumption of a heavy duty diesel vehicle over various driving cycles - GMC Astro 95, 8v-71 na. Technical report

OSTI ID:5553828

This report presents exhaust emissions and fuel economy measurements for one heavy-duty diesel vehicle operated over various driving cycles. These driving cycles were developed from actual in-use operational data collected in New York and Los Angeles under the CAPE-21 program. In each location, data collected for freeway and non-freeway operation was segregated. A data matrix (relating speed, acceleration and frequency of occurance) was prepared for each city and type of operation. The test program was designed to evaluate the concept of chassis testing for large diesel vehicles. Along with this goal, it was desired to determine emission factors and fuel consumption by category of operation and to determine the variation with vehicle load. Also, to verify the cycle generation technique, the sensitivity of emissions and fuel consumption was to be established. Finally, the effect of 'linearized' cycles, steady state tests cold start operation were evaluated.
