This study is based on numerical analysis of scavenging process of two stroke SI engine in two cases i.e. one with existing piston model and another with new piston model. The aim of this analysis is to study the process of scavenging and suggest modifications in order to increase its effectiveness. To simulate and analyze flow through engine three dimensions finite volume method with dynamic meshing is used. The modeling of piston was done in CATIA V5R20 and numerical analysis is performed on CFD Software ANSYS Fluent V 15.0.07.
