Abstract

A 3-dimensional finite element model was developed for the analysis of the automotive diesel engine piston. The model, which consists of a full piston to accomodate the eccentric bowl in the piston crown, is used to calculate steady state operating temperature, thermal stress and thermal deformation of the piston. Roundness measurement tests, which are new approaches to the analysis of piston abrasion and deformation, were done for the comparision of two states of a piston-before and after operation. Numerical prediction shows good agreement with roundness measurement test results.
