CFD Analysis and Modification of Muffler of 1067 cc4 Cylinder Inline Engine for Better Performance

Tridib Kumar Mahata

Abstract


Back pressure is one of the important parameter which determine the performance of the muffler. Pressure drop of the exhaust system includes losses due to piping, silencer, and termination. The most critical mechanical factor regarding backpressure of any commercial modified and available muffler is cross flow perforated tube in which the diameter of the perforated tube hole and porosity of the perforations are most critical. In this paper, the objective is to study and to reduce the backpressure on a 4-cylinder 1067 cc engine by making design changes in its muffler followed by computation fluid dynamics (CFD) analysis for its better performance.
