exhaust system

The exhaust system is a channel to remove the waste products of combustion in internal combustion engines. The exhaust system consists of several components, comprising at least one exhaust pipe known in Indonesia as well as the exhaust is adopted from the Dutch or filter sound.

design

Design drains designed to channel the gases of combustion engine to the place that is safe for the user machine. Generally hot combustion gases, for it must be heat-resistant drain and quickly release heat. Sewer must not pass through or adjacent to combustible material or easily damaged by heat. Although it seems simple, the design of the exhaust system enough to affect the engine performance.

The main components

Scheme exhaust system: 8 Combustion chamber. 9 Relief valve. 10 Channels waste. 11 Exhaust manifold. 12 Catalytic converter. 13 Muffler.

Generally, the components in the exhaust system consists of:

 

> Cylinder head, where the exhaust pipe starts, except for two stroke engines where the drain is placed at  the bottom of cylinder wall.
> Exhaust manifold or exhaust headers, which pipes of some combustion chamber / cylinder join. 
> Catalytic converter to reduce levels of toxic gas, CO, HC and NOx
> Muffler, pipe gas to flow of combustion.
> Silencers or mufflers also called, which serves to muffle the sound. In motorcycles, silencer inside exhaust while the car is generally seen clearly in the form of a tube before the end of the exhaust pipe.
In addition there is an optional component such as turbocharger, which uses the power / energy remaining to turn a turbine to allow air to be inserted into the fuel pressure so the engine will produce more power.
