The role of a catalytic converter in a car is to reduce the harmful emissions produced by the combustion engine. It is a key component of the vehicle's exhaust system. The catalytic converter contains a catalyst, usually composed of platinum, palladium, and rhodium, which facilitates chemical reactions to convert harmful pollutants into less harmful substances.
Specifically, the catalytic converter helps to reduce three main pollutants:
By catalyzing these reactions, the catalytic converter significantly reduces the emissions of harmful pollutants from the vehicle's exhaust, helping to minimize air pollution and improve overall air quality.
