This study has been undertaken to investigate the An Aqua Silencer is mainly dealing with control of emission and noise in automobile exhaust. By using activated charcoal, perforated tube and outer shell it is constructed. An aqua silencer is fitted to the exhaust pipe of engine. The activated charcoal filters the harmful sulphur and nitrous content produced from the engine. Sound produced under water is less hearable than it produced in atmosphere. This mainly because of small sprockets in water molecules, which lowers its amplitude thus, lowers the sound level. Because of this property water is used in this silencer and hence its name aqua silencer. It is tested in single cylinder 4- stroke diesel engine the noise and smoke level is considerable less than the conventional silencer. The main pollutants contribute by automobiles are CO, HC, Nox etc. The Aqua Silencer will reduces the hazardous content in the exhaust silencer.
