A catalytic converter is a device found in the exhaust system of many modern vehicles. Its purpose is to convert harmful pollutants in exhaust gases into less harmful substances before they are released into the atmosphere.
Catalytic converters work by using a series of chemical reactions to break down pollutants, such as carbon monoxide and hydrocarbons, into less harmful substances like water and carbon dioxide. These reactions are facilitated by a precious metal catalyst, typically platinum, palladium, or rhodium, which is coated onto a ceramic or metallic honeycomb structure inside the converter.
The use of catalytic converters has significantly reduced the amount of harmful pollutants released by vehicles, improving air quality and protecting public health. In addition, catalytic converters can also improve a vehicle's fuel efficiency and performance by reducing exhaust back pressure.
Despite their benefits, catalytic converters can become clogged or damaged over time, which can affect a vehicle's performance and emissions. Regular maintenance and replacement of catalytic converters is therefore important to ensure they continue to function properly.
