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

The catalytic converter's primary function is to reduce harmful emissions produced by the engine. It achieves this by converting toxic gases such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances through chemical reactions. This process not only helps in minimizing the environmental impact of vehicle emissions but also ensures compliance with regulatory standards for air quality.

While optimizing engine power, increasing fuel efficiency, and enhancing sound quality may be associated with the overall performance and modifications of a vehicle, these functions are not the main purpose of the catalytic converter. Instead, its designated role is crucial for environmental protection and public health.
