FEA is used in this research to describe the stress distribution of a seizure on a piston four stroke engine. Computer-aided design (CAD) software is used to do the finite element analysis. The major goal is to explore and analyse the thermal stress distribution of the piston during the combustion process in a real engine. The mesh optimization is described in this study, which uses a finite element analysis technique to anticipate the component's greater stress and critical region. The piston's upper end, which includes the piston head/crown, as well as the piston skirt and sleeve, is optimised to reduce stress concentration. The structural model of a piston will be developed using computer-aided design (CAD) and Pro/ENGINEER software. Furthermore, the finite element analysis was carried out with the ANSYS software.
