Aqua Silencer

An Aqua Silencer is used for control of emission and noise in automobile exhaust. By using activated charcoal, perforated tube and outer shell it is constructed. An aqua silencer is connected to the exhaust pipe of engine. The activated charcoal filters the harmful sulphur oxides and nitrogen oxides content produced from the engine. Sound produced under lime water is less hearable than it produced in conventional silencer. This mainly because of small sprockets in water molecules, which lowers its amplitude thus, lowers the sound level. Because of this property lime water is used in this silencer and hence its name AQUA SILENCER. It is tested in single cylinder 4- stroke petrol engine the noise and smoke level is considerable less than the conventional silencer. The main pollutants contribute by automobiles are Carbon monoxide(CO), Unburnt Hydrocarbon(HC),Oxides of nitrogen (Nox) and Lead etc., other sources such as electric power generating stations, industrial and domestic fuel consumption, refuse burning, industrial processing. An aqua silencer is used control of emission and noise. Air pollution is very serious problem for the public health of view, because every person breaths approximately 22,000 times a day, inhaling 15 to 22 kg of air daily. Air pollution effect on living things. The main component due to which air pollution is increasing are carbon- dioxide, which is get exposed from vehicles and other harmful gases which is comes out from the big factories, electric power, generation plants, big industries etc.
