The Effect of Thermal Behavior on Piston Design for Internal Combustion Engines

Abstract

This paper deals with a theoretical and analytical study of three real pistons ofinternal combustion engines (work with gasoline). These pistons are different from eachother in shape, speed ,and power. Three dimension (3D) models for the real pistons werebuild using Ansys software. The boundary conditions were set in order to carry out thethermal analysisThe thermal analysis covered also cases of different changes in the shape of eachpiston in order to carry out comparisons with the real shapes of the pistons.The analysis offers to the designer the ability to understand the behavior of thermalstresses, their locations and the way they spread in order to reach to the optimum design.
