What is the function of a catalytic converter?

The function of a catalytic converter is to reduce harmful emissions produced by the engine during combustion. It is designed to convert toxic gases such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances like carbon dioxide and nitrogen before they are released into the atmosphere. This process is crucial for meeting environmental regulations and improving air quality.

The catalytic converter operates through chemical reactions facilitated by catalysts, which typically comprise precious metals such as platinum, palladium, and rhodium. These materials help break down harmful components in the exhaust gases, making it an essential part of a vehicle's emissions control system.

While enhancing engine power, improving fuel economy, and cooling the engine might be desirable characteristics or functions in a vehicle, they are not the primary purpose of a catalytic converter. Its main goal is strictly focused on emission control and environmental protection.
