A catalytic converter is a device located in the exhaust system of a vehicle that helps to reduce harmful emissions. It uses chemical reactions to convert toxic gases and pollutants in the exhaust into less harmful substances. Specifically, the catalytic converter converts carbon monoxide into carbon dioxide, hydrocarbons into water vapor and carbon dioxide, and nitrogen oxides into nitrogen and oxygen. This helps to reduce the amount of harmful pollutants that are released into the environment, improving air quality and reducing negative health effects. Catalytic converters are required by law in most countries for all modern gasoline and diesel engines.
