What you need to know about a Catalytic Converter
22 April 2020
Pollution is a big issue that can affect everyone. Pollution from cars and other vehicles is a major contributor to poor air quality around the UK. Some inner-city areas in the UK have been recorded as having harmful levels of pollution at peak times. This can mean that it can be harmful for people to be breathing in this level of pollution.
Keeping pollution down
Catalytic converters are devices that use specific substances as a catalyst that help to convert harmful vehicle emissions into something less harmful. Harmful gasses are passed over the catalyst, which is usually a thin layer of platinum, rhodium and/or palladium, this causes a chemical reaction which changes the harmful gases into something less harmful. Catalytic converters have been fitted to all new cars since 1992, with all cars made since 1993 required to have a catalytic converter fitted in order to pass an MOT.
Reducing harmful emissions
Modern catalytic converts can reduce the emissions of carbon monoxide, nitrogen oxides and hydrocarbons. When these emissions are passed over the catalyst, it them into nitrogen gas, which comprises 78% of air in the atmosphere, carbon dioxide and water vapour, all which are far less harmful than the original emissions.
Replacing a catalytic converter
A catalytic converter can be expected to last between 100,000 and 150,000 miles, although they may fail sooner if conditions are not ideal. A catalytic converter failure will be shown by the engine management light coming on. The engine management light can signify many different issues so if it comes on, then contact Motorvation and we will investigate the problem. If it is a catalytic converter problem, we can supply and fit a new one and have you back on the road in no time at all.
