Gas Flow Analysis inside Combustion Chamber of Two Stroke SI Engine

Abstract

Computational Fluid Dynamics has become an essential tool in the design and development process of IC-engines. Due to increasing computer hardware performances and steady decreasing costs it is to expect that simulation technology becomes an unavoidable tool for the analysis of many technical problems. In present study the flow analysis of the charge in the cylinder of 2 stroke SI Engine using CFD ANSYS fluent is carried out. The variation of pressure, velocity, temperature of charge during its flow from inlet to outlet is studied. The effect of thermal barrier coating (TBC) on the piston crown is analysed. This study may help to optimize the engine performance.
