A catalytic converter is a device in a vehicle’s exhaust system that helps reduce harmful gases, such as carbon monoxide, nitrogen oxides, and hydrocarbons, before they are released into the air. It works by using a chemical reaction to convert these harmful gases into less harmful substances like carbon dioxide and water vapor. The catalytic converter is important for improving air quality and ensuring that vehicles meet environmental standards.
