Abstract: Heavy-duty engine certification testing uses a cycle that is scaled to the capabilities of each engine. As such, every engine should be equally challenged by the cycle|s power demands. It would seem that a chassis cycle, similarly scaled to the capabilities of each vehicle, could successfully bridge the gap between ||universal driveability|| and ||realistic engine exercise||. The purpose of this paper is to present just such a cycle.

Keywords: chassis cycle; driveability; heavy duty truck test cycles; engine certificate testing.
