Why is the Exhaust System so Important?
Every component of your car or van has been carefully designed to provide an efficient service in the overall running of the vehicle, from the intricate elements of the engine to the compact nature of the electrics. The exhaust system is no different, playing a key role in the operation of your car.
So what makes the exhaust system to vital?
With all of the fuel that must be burned to create the combustion needed to propel a vehicle forwards, it’s no surprise that a number of noxious gases are generated as a by-product. Many of these can be particularly damaging, including: carbon monoxide, nitrogen oxide, sulfur dioxide, phosphorus, lead and nitrogen monoxide.
This is why exhaust systems contain what’s known as a “catalytic converter”. This vital component transfers harmful hydrocarbons and carbon monoxide into water vapour and carbon dioxide – elements that are not quite as dangerous for the environment. While it is not technically illegal to own a car without a catalytic converter, there are laws that govern the amount of dangerous emissions a vehicle can create, and a car without this component (or a worn down one) would surely be in breach of this.
As well as reducing dangerous emissions, the exhaust system is crucial for ensuring that the high temperatures produced during combustion are recirculated back into the chamber. Many of the vehicles that may come into contact with the exhaust system also have preventative measures in place to stop excessive heat from passing into other vulnerable parts. These heat management components include heat shields, thermal barrier coating and heat wrap, working to absorb or dissipate the heat accordingly.
Due to the nature of combustion, the process can be an extremely noisy one. It falls to the exhaust system to reduce the noise created, through a part known as the muffler. This component works as a silencer, consisting of a metal box that holds a number of “baffles” – tubes that are sometimes perforated to absorb sound energy.
Exhaust systems contain a sensor that detects the amount of oxygen in the exhaust gas makeup. Sending a message back to the computer’s onboard computer, this helps to regulate the amount of fuel required by the engine, leading to a far greater level of fuel efficiency.
With the importance of the exhaust system evident, it’s vital that yours is kept in the best condition possible to ensure that your vehicle runs at an optimum level. Rust is a particular issue with many exhausts, increasing the chances of the system suffering from cracks or other damage.
Make sure your exhaust is regularly examined by experienced mechanics, such as those at Keelers Service Centre, to avoid suffering major issues with your vehicle further down the line.
