EXHAUST SERVICE AND REPAIRS
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
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.
CATALYTIC CONVERTERS – PROTECTING THE ENVIRONMENT
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.
OXYGEN SENSORS - REDUCING YOUR FUEL BILL
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!
