Abstract: Air pollution is one of the major problem in the present world. In this study, we will discuss about the design and fabrication of the charcoal silencer which is fitted to the exhaust pipe of engine and another advanced design of emission control silencer. The charcoal silencer controls both air pollution and sound pollution. The small size of wet charcoal is placed between the honeycomb shape filters and by using this charcoal silencer sound also reduced. The charcoal silencer tested in the laboratory and its smoke level and noise levels are compared with the ordinary silencer.
