Alan Kent Motors Catalyst Replacement.
What does my catalytic convertor do? All modern petrol car exhausts manufactured from 1993
|The good news is that catalytic convertors have a good life expectancy, but still need to be checked periodically for internal and external damage. Another device that helps to reduce carbon emissions is the oxygen or lambda sensor. |
This monitors the percentage of oxygen present in exhaust gases and transmits information to the engine management system or electronic control unit (ECU). The ECU - using information obtained from
the oxygen sensor - constantly adjusts the air/fuel mixture so that the cleanest and most efficient combustion is achieved under all operating conditions. Sometimes, a 'failed' catalytic converter can be due
to a fault in the engine management system. In these circumstances a new catalytic converter may not rectify the problem. So the oxygen sensor, catalytic convertor and ECU all work together to help to
achieve the lowest possible output of dangerous
and polluting gases.
