Introduced to Australian motor vehicles in 1986, catalytic converters were fitted to unleaded petrol vehicles to clean up the noxious exhaust gases produced during operation. The role of the catalytic converter is to control the harmful emissions from the combustion process by converting the Hydrocarbons (HC), Nitrogen Oxides (NOx) and Carbon Monoxide (CO) into Carbon Dioxide (CO2), Nitrogen (N2) and Water Vapour (H2O).
The catalytic converter is designed to last the lifetime of the vehicle, but this is not always the case. The premature failure of the catalytic converter could be attributed to poor tuning of the vehicle’s ignition, a lack of servicing at regular intervals, road impact damage, driving through deep water or using non-compatible fuels and additives. These conditions need to be avoided by the owner of the vehicle in order to ensure a healthy catalytic converter.
