Design and Analysis of Piston for Four Stroke IC Engine

These Piston is the part of engine which converts heat and pressure energy liberated by fuel combustion into mechanical works. Engine piston is the most complex component among the automotive. This paper illustrate design procedure for a piston for 4 stroke petrol engine for Bajaj Pulsar bike and its analysis by its comparison with original piston dimensions used in bike. The design procedure involves determination of various piston dimensions using analytical method under maximum power condition. The objective of this thesis is to develop the geometry of piston of four stroke IC engine and to investigate the maximum stress using Solidworks software. In static-structural analysis, the pistons were analyzed using different grade aluminum alloy material and find out the stress, total deformation and strain & its effect on piston behavior. For analysis using von-mises stress theory. From the analysis it was found that, the maximum stress intensity found on the surface of the piston crown in material, but stress intensity is close to the permissible strength of Al alloys piston.
