Experimental Investigation on Innovative Modification of Aqua Silencer

Abstract

One of the major threats to the society and environment is considered asair pollution which causesill effects to the human beings as well as environment. The main contributor to the air pollution is gases releasing from automobiles like carbon dioxide, unburned hydrocarbons etc. In view of addressing this major contributor, paper focused on modification of conventional silencer by introducing redesigned Aqua silencer that minimizes generation of such polluting agent. Aqua silencer is mounted similar to conventional silencer with minor modifications to the exhaust pipe of the engine. In modified aqua silencer emission is controlled by theactivated charcoallayers. Environment harmful gases are absorbed efficiently within the silencer and keep automobile environment friendly. Aqua silencer also addresses the noise pollution concern as sound produced within water is less audible because of smallsprocketsin water molecules lower its amplitude and so lowers the sound level. Aqua silencer is designed and developed at Mechanical Engineering Department, Government Engineering College, Bhavnagar and experiments were carried out by mounting aqua silencer on very high load engine like Diesel generator set. Performance indicators are measured and compared with conventional silencer used in diesel generator. Opacity of carbon particles is reduced up to 32.7%. However, few barriers and challenges that have been identified in this article must be addressed carefully before aqua silencer employed by the automobile industry.
