Exhaust System. How important it is? 0

exhaust systemMain parts of an exhaust and how they work…

Your exhaust system’s condition is paramount to your car’s overall performance and health. The fuel consumption can be affected as well as your own safety, depending on the state of your exhaust system. Its general purpose is being responsible for acting as a path to transport the burnt exhaust gases from the engine out to the tail pipe.   The gases in question are created when the fuel and air are burnt together in the combustion chamber.

Exhaust Pipe: This is the physical bit of the system which is mainly visible when viewing a car. The pipes as mentioned before are indeed responsible for carrying the gas through from the engine to the tail pipe. The gas is created from the engine and then sent through to the exhaust manifold, which passes the gas out towards the tail pipe. They are usually made from Aluminium, steel or metal.

Exhaust Manifold: This is connected to the side of the engine, making it the first direct part of the exhaust to receive the burnt gases of which are created within the engine. The gases are then passed on from here to the tail pipe, and then let out. The manifold can gather a lot of heat and can reach a blistering temperature. It may also burn more fuel that wasn’t burnt properly by the engine. The manifold is commonly made of cast iron, stainless steel or aluminium.

Muffler: Mufflers are within a car exhaust that contains the gas being passed through it from the engine. The gas must pass through a muffler, which can also act as a sound barrier in which noise levels are kept down to a reasonable level. Mufflers are made within a metal container that uses the energy of the burnt gases in order to quieten the noise.

Oxygen Sensor: This is built within modern car’s exhaust systems. They allow fuel injection, fuel economy calculations as well as emission control to be utilised. It measures how much oxygen is left within the exhaust system.

The Tail Pipe: This is the last point of the exhaust system whereby the gases passed from the engine have reached its final point. From here the exhaust gas is funnelled out into the air.

Catalytic converter:  This part of the exhaust systems brings about safe compounds through the exhaust from those compounds being harmful. It uses a catalyst to convert Hydrocarbons, Carbon monoxide and Nitrogen oxides (on specific converters). The catalyst can also help convert carbon monoxide into carbon dioxide, as well as hydrocarbons into carbon dioxide and water.  It is positioned between the muffler and the exhaust manifold.
