An Experimental Study of the Impact of Piston Pin Offset upon Friction Losses and Noise of EQQ6100 Gasoline Engine

摘要

Through the ral-time measurements of friction force and noise in a firing gasolbine engine, the impact of the piston pin offset, both in major and minor throust faces, upon friction horsepower and noise of a model EQ6100 gasoline engine is nvestigated. The results show that piston pin's ffset in minor thrust face can reduce friction horsepower of the negine, but has little effect on its noise.
