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