Exhausts play a vital role in your car. It’s one of the 4 basic operations of your 4 stroke engine. Here are the 4 strokes of your engine, 1. Induction (Introducing air and fuel into the system), 2. Compression (The fuel and air are compressed and heated up ready for ignition), 3. Ignition (The fuel and air mixture are ignited and this provides the power that turns your wheels), 4. Exhaust (The gasses that are produced during ignition are expelled from the system so the process can start again). Now with out any of these strokes your car will not provide any thrust to turn your wheels.
Expelling the air during the exhaust stroke cannot just be dumped out into the engine bay. As this stroke also plays a part in inducting new air into the system. As a result, over the years, car manufacturers have fitted a complex exhaust system to your vehicle. This includes many pieces of equipment such as boxes that clean the fumes, valves that recirculate the air back into your engine when there is unburnt fuel and a massive number of sensors to ensure your car is operating as normal.
It’s important to look after your exhaust. With the system as complex as it is, a poor condition or broken exhaust will lead to MOT failure. However, it’s not just the MOT that is an issue. Your car can be noisier, worse for the environment but even more, you can actually have a massively increased fuel consumption as the car computers attempted to make up for the failures in your exhaust system.
Getting your exhaust system checked regularly will save you time, money and ensure your MOT is much less stressful for you.
Making sure your exhaust is checked is important however, the garage that do the checks also plays a vital role. You should always ensure you choose an exhaust garage that understands how the system works from start to finish. Different mechanics have different specialities so choose carefully.
