22. A REVIEW ON DESIGN & ANALYSIS OF REACTIVE TYPE SILENCER

IC engines are one of the major sources of noise pollution. Mufflers (Silencer) are generally found with exhaust framework. After the ignition the focused energy gas pressure through the suppressor chamber and a portion of the gases reflected again goes through the burning chamber it is gotten back to pressure. It makes vacuum pressure in ignition chamber and diminishes the motor exhibition. Decrease of weight, expanding the ability of commotion ingestion from the suppressor with insignificant back pressing factor can build the exhibition of the motor. The goal of this investigation is to optimize noise l evel of engine and reduce back pressure. This project mainly targets on designing a muffler to reduce the noise and back pressure. Based on new muffler design parameters, a model is fabricated and tested . Key wo rds :- Silencer , Automobile
