Design, Development and Analysis of Resonator Chamber type Muffler for I.C Engine

Man’s desire for a pollution free atmosphere needs reduction or control of noise pollution from the sources such as automobile engines, power plants and Industrial installations. The principal sources of noise in automotive engines are intake noise, radiator noise, combustion noise, exhaust noise, etc. Out of these, exhaust noise is predominant and it is to be controlled. Physiologically and psychologically effects are seen as pollution affects human beings. So the silencer or muffler is a part of the exhaust system on an automobile that plays a vital role in reduction of the noise and pollution. The main objective of this study is to propose an exhaust silencer or muffler design which one reduces a large amount of noise level and back pressure of the engine. The present paper deals with the design analysis and performance evaluation of the silence develop with features of noise and pollution reduction for an agriculture application engine. The system draws inspiration for a design named Helmholtz silencer which uses a resonating chamber.
