About Structural and Thermal Analysis of Diesel Engine Piston Using Ansys Software

摘要

The main role of the piston is to vary the dimensions of the combustion chamber in internal combustion engine.The piston is in contact with the hot gases resulting from combustion.In addition to thermal stresses,depending on the operating mode of the engine,the piston is required to alternate the inertial force.Therefore,the steel piston undergoes due to high inertial forces,and lightweight aluminium pistons cannot operate at high temperatures.In order to combine the advantages of the two types of materials it has been chosen the constructive design of the bimetal pistons.This paper aims to compare the performances of steel pistons and bimetal pistons using the Ansys software.
