DESIGN AND THERMAL ANALYSIS OF PISTON SUBJECTED TO DIFFERENT MATERIALS USING CAE TOOLS

Abstract

An IC engine is one in which the combustion of fuel takes place inside the engine cylinder. IC engine uses
either petrol or diesel as their fuel. In petrol engines (S.I engines) the correct proportion of air and petrol is mixed
in the carburetor and fed to engine cylinder where it is ignited by means of a spark plug. The steps involved in a 4
stroke IC engine are suction stroke, compression stroke, and expansion stroke and exhaust stroke. One of the main
components in an IC engine is the combustion chamber. The design of a combustion chamber has an important
influence upon the engine performance and its knock and air swirl properties. Design of a combustion chamber
involves the shape of the combustion chamber, location of the spark plug and the position of the inlet and exhaust
valves. In this project, two different materials (Structural Steel and C35 Steel) are considered. Thermal Analysis is
carried out on a piston using different materials. Performance parameters are calculated. Catia is parametric used
for design and Ansys workbench used to perform thermal analysis of model piston.
