Abstract: ABSTRACTThe Brazilian "Inovar-auto" tax program brings the need to improve engine fuel efficiency. In this paper, the impact on fuel savings by using low friction components was evaluated on representative Brazilian ethanol fueled engines. The vehicle certification cycles, and the typical urban drive, focus on low engine speed-loads where the mechanical losses are around 10% of the fuel energy. To define design changes on the engine components with more fuel saving potential, a proprietary simulation tool was…
