Frequently Asked Questions About Catalytic Converters
How does a Catalytic Converter work?
Catalytic converters work by using a catalyst to facilitate chemical reactions that convert harmful pollutants into less harmful emissions before they exit a vehicle’s exhaust system. These devices contain a core made of ceramic or metal, often coated with catalyst materials such as platinum, palladium, and rhodium. When exhaust gases pass through the catalytic converter, the reduction catalyst and oxidation catalyst work in tandem. The reduction catalyst reduces nitrogen oxides to nitrogen and oxygen, while the oxidation catalyst converts carbon monoxide and hydrocarbons into carbon dioxide and water vapor. This process significantly reduces the emission of harmful gases into the atmosphere, making it an essential component of modern automobile exhaust systems.
