The exhaust system is one of the most important parts of your car or van. Its main purpose is, of course, to get rid of the waste gases produced by the engine, although it also has many secondary functions.
If you're in North West London, bring your car down to us in Colindale or Hendon for a full service, including an exhaust and catalytic converter check.
Exhausts are also supposed to reduce the noise made by your engine. This is achieved with an array of baffles and other materials that muffle sound. Special resonator units are used in some systems, to be even quieter.
A catalytic converter's job is to transform harmful gases into something less dangerous. Engines produce such gases as carbon monoxide, nitrogen monoxide and VOC gases. A reduction catalyst splits these harmful molecules up into less troublesome elements and an oxidation catalyst adds extra oxygen molecules so that the dangerous gases are less of a problem.
Due to recent legislation, your car has to pass an emissions test - if you don't fall below the required emissions level, you'll fail your MOT! So get your catalytic converters checked out, and replaced if necessary.
Does your car use fuel injection? It'll have an oxygen sensor in the exhaust. This sensor works out how much oxygen is in the exhaust, and can use that information to optimise the amount of fuel burned. It also makes sure that there is enough oxygen in the exhaust gases for the oxidation catalyst to work.
But if your oxygen sensor is blocked, it'll send incorrect readings to your engine computer. That means you'll burn more petrol than you need, burning up cash. It's better to spend that cash getting your exhaust regularly checked!
