Every automobile uses an exhaust system for two major reasons; to expel unwanted gases into the surrounding and to reduce the sound made by the engine into its barest minimum. The system rusts both from the inside and the outs The exhaust consists of; the exhaust manifold, mid-pipe, catalytic converter, exhaust pipe, muffler/silencer, and the exhaust pipe tip (tail pipe). 1. The exhaust manifold; The exhaust manifold helps to collect the gases from the engine. 2. Catalytic converter; This is an emission control device that converts toxic gases and pollutants in the exhaust gas to less toxic pollutant by catalysing a redox reaction. For instance the carbon monoxide(CO) reacts with oxygen(O 2 ) and unburned hydrocarbon to form carbon dioxide (CO 2 ) and water (H 2 O). 3. Muffler/ silencer; Every engine produces supersonic sounds which are not palatable to the ear. So there is need to device a system to reduce this noise. The silencer consists of a baffle...
