A study on design and analysis by varying piston material in SI engine

Abstract

The piston in an internal combustion engine is exposed to high temperature and pressure for a long time. Generally, when designing a piston, the material used must have a high melting point and tensile strength. In this paper, the design research and structural analysis of the piston of a four-stroke spark ignition (SI) engine was carried out by changing the composition of the piston material with various materials such as titanium alloy, magnesium alloy, gray cast iron, aluminum alloy and structural steel. The study investigated mechanical strain and the mechanical stress, deformation, heat dissipation, and heat-flux. This study concluded that under assumed conditions, depending on other piston parameters, titanium alloy creates optimal conditions for the piston.
