STUDY OF NOISE BEHAVIOR ON MUFFLERS FOR IC ENGINE: A REVIEW

The aim of this paper is to analysis the Muffler for four stroke diesel engine. Muffler or silencer is a device which is used for reducing the amount of noise emitted by the exhaust of an internal combustion engine. After burning the fuel the many poisonou s exhaust gas such as CO2, SO2, NO2, are generate. Such types of harmful exhaust gases are generate noise and air pollution. Exhaust noise from IC engines is one of main factor of noise pollution to the atmosphere. Day to day, noise pollution increases in our surroundings due to increase of number of vehicles and automobiles. Mufflers are installed within the exhaust system of most I C engines, although the muffler is not designed to serve any primary exhaust function. The muffler is an acoustic soundproofi ng device designed to reduce the noise of the sound pressure created by the engine. The majority of the sound pressure produced by the engine is to reduce approximately 10db to 15db after passing the exhaust gas through muffler.
