Abstract
This paper shows a study for solving a piston skirt scuffing problem in diesel engine. We propose to solve this scuffing problem by studying the piston dynamics analysis using commercial S/W; ABAQUS. The first approach was to develop the piston secondary dynamic analysis method based on the Finite Element Method. The second approach was to clarify the root cause of the diesel piston scuffing case. The last approach was to optimize the piston skirt profile and cylinder block design for reducing the scuffing index. The solution proposed in this study was adopted in the piston and block design.
