WHAT DOES YOUR EXHAUST DO?

The car exhaust system is a vital part of your vehicle and one that is responsible for many things to keep your car running smoothly, each impacting how the car performs or affecting the safety of the vehicle.

What is an exhaust system and what does it do?
A common misconception about the exhaust system is that it’s very small and located at the back of your vehicle, however the exhaust system of a car is actually made up of several parts and spans almost the entire length of your car.

Your car exhaust system has four main jobs to do:
1. Control and minimise noise
2. Redirect exhaust fumes created by the engine
3. Improve the engine’s overall performance
4. Improve fuel consumption.

How does it work?
Your car’s exhaust system is a series of tubes and chambers designed to move gas away from the engine and reduce the noise that it makes. The several different components are the exhaust manifold, oxygen sensors, catalytic converter, diesel particulate filter, silencer and exhaust pipe.
The most important functions of the car exhaust system is that it redirects dangerous gases away from passengers. Your car exhaust emissions system is crucial for your car to operate safely. There are six gases produced by the basic function of your car’s engine: nitrogen gas, carbon dioxide, water vapor, carbon monoxide, nitrogen oxides, and hydrocarbons. The exhaust system collects these noxious gases, removes the hazardous elements of these gases before safely distributing them out of the car and into the outside atmosphere.

How do I know my exhaust is working properly?
As such a crucial part of your car, you’ll want to ensure that your exhaust system is always running smoothly. However, if you’re not sure of the warning signs, here are some things to look out for in the event that you might need an exhaust repair or replacement:

– If your exhaust system emits a rattling, vibration or increased engine noise, this is an indicator that your exhaust system may have an issue and needs to be checked out by a professional.

– If you can visually see any damage, such as cracks or holes when looking at your exhaust, particularly where the different sections of the system meet, you should get your vehicle checked by a professional. If you also spot rust when inspecting your car exhaust system, this might not automatically be an issue, but is worth getting checked to be on the safe side.

It’s good to get your exhaust checked at least twice a year for any damage that could occur. If you have any concerns about your exhaust, drop in to Roadwheel or give us a call and we’d be more than happy to have a look.
