Abstract: The purpose of the exhaust system in all automobile vehicle is simply to channel the fiercely hot products of fuel combustion away from the engine or generator and the car’s occupants and out into the atmosphere. The main purpose of the exhaust system is to reduce the noise. The gases that are getting exhausted from the engine will be at high speeds. Because of the opening and shutting of the exhaust valves in each cycle of combustion, the gas pressure changes from high to low, this cause vibration and hence produces heavy sound. Due to the continuous operation of the engine the silencer becomes too hot. It will injure seriously if anyone touches it with naked body. The dimple silencer will have increase in the rate of heat dissipation, because of the dimples provided on the surface of the silencer. The dimples on the silencer will perform a function similar to that of the cooling fins of an IC engine. The dimples act as the extended surface over the surface of the silencer & provides better heat transfer rate. In this work clear Analysis is made using Ansys software for Normal & Dimple Silencer and Results are compared with the rate of Heat dissipation.
