Numerical Simulation for Effects of Running Surface Profile Structure in Piston Ring Group on Blow-By and LOC

Article Preview

Abstract:

The oil film distribution of piston ring lubrication is determined by the running surface profile of piston ring, which has significant effect on lube-oil- consumption (LOC) and blow-by of diesel engine. Based on the Excite Piston&Ring software in AVL Company, the effect of changing the running surface lines of piston ring group on LOC and blow-by of a automotive diesel engine has been analysed, which contributes to the design of piston rings. The results show that the performance of blow-by and LOC in scheme two is better than that in scheme one.
