A catalytic converter is a device that reduces harmful emissions from internal combustion engines. It is located in the exhaust system and contains a catalyst, usually platinum or palladium, that promotes chemical reactions that convert pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances such as carbon dioxide, water, and nitrogen.
Catalytic converters are an important part of modern vehicles and are required by law in most countries. They have significantly reduced air pollution and improved public health. However, catalytic converters can become clogged over time, which can reduce their efficiency and lead to increased emissions.
