Buying a vehicle is a dream that many people have. If you plan to get one, for personal use or to use as a taxi, you probably have a list of desired features for your car. However, you must know the parts of a vehicle before you purchase one, so it would be easier to understand what to do if there is a problem. With this, one crucial car part you should learn about is the exhaust system.

What is an Exhaust System?

An exhaust system refers to the vital vehicle part responsible for guiding exhaust gases out of your vehicle. It is composed of many pipes and pieces that provide a way for the exhaust gases to escape the vehicle’s engine. Exhaust systems typically comprise various diesel parts like the exhaust manifold, catalytic converter, resonator, muffler, and tailpipe. Depending on the overall design of the exhaust system, exhaust gas can flow through one or more of these parts.

The Components of Exhaust System

Along with the 12 valve Cummins injectors and fuel system of a vehicle, it is also crucial to learn about the components of a diesel exhaust system. Each part of the exhaust system is designed to serve its specific purpose, vital to how a vehicle’s engine functions on the road.

  • Exhaust Manifold

This component is connected directly to the engine, which collects the exhaust from each cylinder before combining it into one pipe. A vehicle can have one or more exhaust manifolds depending on the engine’s size. 

  • Oxygen Sensor

This component measures how much oxygen is present in the exhaust. Most vehicles have two oxygen sensors that help benefit fuel economy and provide optimal performance. 

  • Catalytic COnverter

A catalytic converter converts harmful gases into water vapor and carbon dioxide. It reduces the vehicle’s emissions and ensures that the gases emitted from the car will be much safer for the environment. 

  • Muffler

The muffler, or the silencer in European-made vehicles, provides noise reduction and soundproofing for a vehicle’s engine. It dampens vibrations created by sound pressure from the engine through acoustic quieting.

  • Exhaust Pipe 

The responsibility of an exhaust pipe is to connect all the exhaust system components of the vehicle. Its design enables exhaust to travel towards the vehicle’s rear in the most efficient manner possible. Exhaust pipes also function to keep the hot exhaust away from sensitive components of the car and the engine compartment and undercarriage of the vehicle. They are usually made of steel, but aluminized steel tubing or stainless steel is a more durable and corrosion-resistant option for your car.
