What is the primary purpose of a catalytic converter?

The primary purpose of a catalytic converter is to reduce harmful emissions from the exhaust system. This component plays a crucial role in the vehicle's emission control system by converting toxic gases such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide and nitrogen. Through a chemical reaction facilitated by catalysts such as platinum, palladium, and rhodium, the catalytic converter helps to minimize the environmental impact of vehicle emissions, making it a key element in meeting regulatory standards for air quality.

While improving fuel economy and enhancing engine power are important aspects of vehicle performance, they are not the primary function of a catalytic converter. The design and operation of the catalytic converter focus specifically on treating exhaust gases before they are released into the atmosphere, thereby addressing the issue of pollution rather than directly influencing fuel efficiency or engine output.
