A catalytic converter is a device that reduces the harmful emissions from a vehicle’s exhaust system. It does this by converting pollutants like carbon monoxide and nitrogen oxides into less harmful substances like carbon dioxide and nitrogen. Catalytic converters are an important part of a vehicle’s emissions control system, and they help to improve air quality.
Catalytic converters are typically made of a ceramic or metal substrate with a coating of precious metals, such as platinum, palladium, or rhodium. These metals act as catalysts, which means they speed up the chemical reactions that convert pollutants into less harmful substances. Catalytic converters are typically located in the exhaust system of a vehicle, after the engine and before the muffler.
