Abstract

It is important to calculate the piston temperature distribution in order to control the thermal stresses and deformations within acceptable levels. In this study, the SI ENGINE PISTON heat transfer is calculated and the piston is thermo-mechanically analyzed using finite element method. In order to calculate the heat transfer, a concise resistor model for wall temperature prediction is used. For each of the walls (piston, cylinder and cylinder head), the relevant heat transfer equations simultaneously with TWO ZONE COMBUSTION MODEL is solved considering three unknown temperature. The simulations were done by a MATLAB code and the result validated with the experimental data of the EF7.TC engine. The above results have been curve fitted and imported by the commercial ANSYS code to loading the piston.To evaluate properly of results, STRESS ANALYSIS results is compared with real samples of damaged piston and it has been shown that Critical identified areas, match well with areas of failure in the real samples.
