Overview-
The Exhaust system of a car is as important as the engine. The exhaust pulls out the harmful gases from the engine compartment into the atmosphere, so that the vehicle can stay safe and functioning. The good exhaust makes the engine nicer and the atmosphere clean.
But somehow the exhaust makes the atmosphere polluted by releasing black and blue smoke. This smoke contains a lot of harmful gases. Both these types of smokes can cost you a lot of money on a daily run and also in terms of repair bills later. The causes of black smoke and blue smoke, I will describe today.
