The objective of this research paper is to investigate whether an energy storing and recovering process, involving compressing air and subsequently using it for power stroke (Expansion stroke), could be used to achieve better overall efficiency. When using fuel, the engine operates as close to or tends to maximum efficiency in practicable, with the excess of engine output over driving requirements being absorbed by air-compression loading - driving any other compressor, charging air into the cylinder. Heat transfer from the exhaust gases to the stored compressed air is used to improve engine efficiency. Through design, simulation and also proper utilization of exhaust gases, an overall efficiency improvement by 10% over standard engine operation is predicted to be reliable by applying to this concept, and scope exists to further improve this figure through improved heat recovery from exhaust gases and improved loading capacity. In this present work a piston and piston ring are designed for a single cylinder four stroke petrol engine using Pro E WILD FIRE 5.0 MECHANICA software. Complete design is imported to Pro E WILD FIRE 5.0 MECHANICA software then analysis is performed. The whole analysis of I.C.Engine depends upon the FEA (Finite Element Analysis ) that is consist of a computer model of a material or design stressed and analysis. Materials have been selected for structural and thermal analysis of piston & piston ring by using Pro E WILD FIRE 5.0 MECHANICA software. Results are shown and a comparison is made to find the most suited design. Key words: Piston, Piston-Ring, Cylinder head, Exhaust valve, Cylinder block, Turbocharger, Pro E WILD FIRE 5.0 MECHANICA. 1. INTRODUCTION DEFINITION OF IC ENGINE “It is type of heat engine in which the chemical energy of the fuel is released inside the engine and used directly for mechanical work, as opposed to an external combustion engine in which a separate combustor is used to burn the fuel.” 2.
