What is the purpose of a catalytic converter in a vehicle?

 

The purpose of a catalytic converter in a vehicle is to reduce the harmful emissions produced by the engine. It contains a catalyst, usually made of platinum, palladium, and rhodium, which facilitates chemical reactions that convert harmful pollutants in the exhaust gases into less harmful substances. Specifically, it helps to convert carbon monoxide (CO) into carbon dioxide (CO2), nitrogen oxides (NOx) into nitrogen (N2) and oxygen (O2), and unburned hydrocarbons (HC) into carbon dioxide (CO2) and water (H2O). This helps to minimize air pollution and meet emission standards set by regulatory authorities.
