Abstract: For this problem that the blow-by of a engine exceeds the standard requirement, this paper gives dynamitic analysis to the piston ring assembly, basing on Excite software through Modeling and reasonable boundary conditions and comparative analysis. An optimized plan is made to reduce blow-by. Engine experiments have improved that the analysis results are correct.
Key Words: Piston ring assembly; Dynamic analysis; Blow-by; Optimization
