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

The primary purpose of a catalytic converter in a vehicle is to reduce exhaust emissions. It plays a crucial role in the vehicle’s exhaust system by converting harmful pollutants in the exhaust gases into less harmful substances before they are released into the atmosphere. The catalytic converter uses a catalyst, typically made from precious metals, to facilitate chemical reactions that reduce emissions of carbon monoxide, nitrogen oxides, and unburned hydrocarbons.

While enhancing fuel efficiency, increasing horsepower, or cooling engine components could be related to overall vehicle performance or design, they are not the main functions associated with a catalytic converter. The focus on reducing harmful emissions is vital for meeting environmental regulations and improving air quality, making it a significant component in modern vehicles equipped with internal combustion engines.
