Abstract

Abstract: This chapter addresses engine friction and lubrication dynamics modeling in diesel engine system design. It starts by introducing important fundamental principles of engine tribology and builds up a three-level system modeling approach of engine friction. The chapter summarizes the friction characteristics and friction-reduction design measures for both the overall engine system and individual subsystems such as the piston assembly, the piston rings, the bearings, and the valvetrain.
