DESIGN AND OPTIMIZATION OF EXHAUST MUFFLER IN AUTOMOBILES

Abstract

The purpose of this research is to enhance the efficiency of the Nash Shell Damper (NSD) muffler so that it can better reduce the amount of pollution that is produced by diesel engines. This will be accomplished by building an exhaust filter that is specifically built for the purpose, given that the exhaust system is responsible for producing the majority of the noise that is generated by the engine. In order to conduct the tests, four-cylinder TATA INDICA TURBOMAX TDI BSIV automobiles were selected. In the current research, the comparison method was utilized to find out the size of the mufflers so that CAD models could be constructed. CATIA V5 R19 was used to construct the CAD models that were utilized for this inquiry. After the CAD models for the muffler had been completed, they were submitted to HYPER MESH so that the preprocessing could begin. The muffler undergoes exhaustive testing with the use of NASTRAN apparatus and the Finite Element Analysis (FEA) technique.
