If you have any questions about the information presented on this page, you can contact us directly to learn more.
Exhaust System Functions
Your car's exhaust system carries away gases created when fuel and air are burned in the combustion chamber. These gases are toxic to humans and the environment.
Periodically inspecting your exhaust system is a must to ensure your safety. An inspection typically starts out by ensuring there are no holes where fumes could enter in the exhaust system or passenger compartment.
Exhaust System Parts
It is important for you to understand the different parts of your exhaust system so that you know how to respond to different types of malfunctions. Fortunately, we can help you understand how each portion works. The parts of your system include:
The exhaust manifold attaches to the cylinder head, taking exhaust from each cylinder and combining it into one pipe. The manifold can be made of cast iron, steel, aluminum or stainless steel.
The catalytic converter converts dangerous carbon monoxide and hydrocarbons to water vapor and carbon dioxide, with some also reducing harmful nitrogen oxides. The converter is mounted between the muffler and the exhaust manifold.
All modern fuel injected cars utilize an oxygen sensor to measure the amount of oxygen present in the exhaust. Based on this, the system can increase or decrease fuel to achieve the appropriate mixture for optimized fuel economy. The oxygen sensor is either mounted in the exhaust manifold or located nearby in the exhaust pipe.
The muffler’s purpose is to minimize exhaust noise. Many mufflers use baffles to circulate the exhaust, dissipating the energy produced and reducing noise. Some mufflers also use fiberglass packing, which also serves to absorb the sound energy as gases flow through the system.
Located between all of the parts discussed above is the exhaust pipe, which ultimately carries the gas out of your tail pipe. Exhaust tubing can be made of steel, stainless steel or aluminized steel.
