Reduction of Friction Losses in Engine Piston and Cylinder
초록
Fuel consumption of a modern combustion engine is significantly influenced by the mechanical friction losses. The reduction of the engine friction losses offers a remarkable potential in emission and fuel consumption reduction. The analysis of the engine friction distribution of modern engines shows that the piston and the cylinder have a high share at total engine friction. The present study uses PISDYN(by Ricardo) software to analyze the friction losses. The design parameters such as skirt profile, center of mass of the piston are shown to have key influences on the friction losses.
