Exhaust System and Its Major components!

A vehicle is composed of a number of system and parts, all designed for its smooth and efficient running. Exhaust system is one of its most integral parts that performs a number of vital functions. It extracts the perilous fumes from the engine of the vehicle. Moreover, it is also required for smooth running of the vehicle. In other words, overall performance and efficiency of a vehicle depend on this system.

A vehicle exhaust system is composed of numerous components, all of which perform an important role in the smooth and safe running of a vehicle.

Chief components of this system along with their functions have been listed below:

</b>Manifold</b>

For powering the vehicle, hot gases are produced by the engine from each cylinder. Whenever the valves of exhaust system open, these hot gases pass into the manifold. The manifold is composed of cast iron and is mounted over the engine cylinder head.

<b>Downpipe</b>

This is another major component that extracts the gases and vapor from the manifold to a different component downstream in the system.

<b>Catalytic convertor</b>

Catalytic converters keep the environment clean by reducing detrimental combustion engine pollutants.

Lambda sensor

This is another major part of the vehicle exhaust system that performs the role of measuring oxygen content of the gases. Once measured, it passes the information to the engine control unit about it.

<b>Front silencer</b>

As far as the composition of the silencer is concerned, it is composed of various parts including tuning chambers, perforated and solid tubes, baffle partitions, all designed to dispel noise pulses to ensure accurate flow of gases via exhaust system.  

Intermediate sensor

This is another important part. The function and design of the intermediate silencer is similar to the front sensor.

<b>Tail pipe</b>

Tail pipe is a very important component that prevents the gases from entering the luggage and passenger compartment. 

All these basic components of the system need routine inspection and maintenance so that they might not encounter any kind of trouble. In case any of the parts develop some problem, they need immediate repair otherwise it can affect the overall performance of the vehicle. Moreover, a damaged exhaust system also causes environmental hazards, increases noise pollution and level of carbon monoxide inside the vehicle that can prove destructive. 

There are many auto service centers that carry out exhaust system maintenance and repair of the vehicles. You can choose a reliable center after doing a deep research.
