Abstract
Due to the inherent nature of combustion in the Cylinder of a Conventional Internal combustion engine, stress variation as well as a certain temperature distribution sets up in the entire piston. Analysis of piston is required because of its shape and it is subjected to both structural and thermal loads. In the present study, piston of a two stroke spark ignition internal combustion engine having maximum power of 6.5 kW at 5500 RPM, has been designed and analysed. The piston made up of Aluminium 4032 alloy is designed by conventional approach and then both thermal and transient structural analysis have been carried out.The piston has been modeled in CATIA and analysed using ANSYS Workbench. In order to improve the design of piston, two alternative designs have been considered by providing openings at the skirt region of the piston. The analysis showed that this modification improved the thermal performance of the piston. An alternative design with large openings at the skirt region showed the best thermal performance
