Abstract
Olson Laboratories, EPA's heavy-duty cycle development contractor, has generated various nominal 5-minute chassis and engine cycles from the CAPE-21 data base. The Emission Control Technology Division of EPA has in turn, selected the best cycle in each category for which cycles were generated (both chassis and engine cycles). The final step in ECTD's HD transient cycle development effort is the arrangement of these five minute cycles into one cycle which exhibits the proper trip characteristics as determined from the CAPE-21 survey data. The purpose of this report is to identify the cycle arrangement that has the proper trip characteristics and which also meets certain practical requirements. Chassis and engine cycle arrangements for both HD gasoline and diesel vehicles are developed. The equations necessary for exhaust emission calculations are also presented.
