Optimization of the Heat Structure of the Internal Components the Engine Component

This work’s main goal is to examine how the thicknesses of the piston boss and piston crown affect the stresses placed on the piston. In the current study, a 150-cc piston of the “Hero” type, constructed of A4031 aluminum, was taken into consideration. Heats from the combustion process and gas pressure were applied to the piston head in a double-action. It was thought that the piston pin bore served as a cylindrical support. The simulation process utilizing the thermal structural coupling technique was conducted using ANSYS 15. A range of piston boss and piston crown thicknesses were chosen and examined. The piston’s Von-Mises stress, mass, and temperature distribution all influenced the comparison and optimization procedures. The results unequivocally demonstrated that the ideal piston design was 3 mm piston crown and 2 mm piston boss thicknesses, based on the stress levels measured for various piston diameters. The ideal piston design raised the piston’s internal temperature while decreasing overall stress and mass.
