Tag: Car Exhaust System

A car exhaust system has three essential functions. They include:

To direct all exhaust fumes from the engine to behind the vehicle
To reduce emissions by decreasing the number of toxic chemicals in the fumes
To reduce the noise caused by the explosions which occur during the fuel combustion process.

A car exhaust system consists of many chambers and pipes. It begins at the engine and goes all the way to the tailpipe at the back of the vehicle.

Most vehicles have four-cylinder engines with a single exhaust. High performance and ‘sporty’ cars like a V8 generally will have twin exhausts.

Most people assume a car exhaust system is only the length of the tailpipe. It’s an easy mistake to make, as this is the only part of the exhaust which is visible (the part right at the very end).

But actually, an exhaust system is made up of six different parts. The average length of an exhaust system is a large 3 meters.

Exhaust System Parts Names

The exhaust system parts names are as follows:

Exhaust Manifold

Oxygen Sensor

Catalytic Converter

Diesel Particulate Filter

Exhaust Pipe

Muffler

Each part has a very different purpose, and for an exhaust system to work correctly, all six parts must be functioning correctly.
