What is the function of a catalytic converter?

The function of a catalytic converter is primarily to reduce the amount of harmful gases emitted from the vehicle's tailpipe. This component is essential in controlling pollution by converting toxic substances in the exhaust, such as carbon monoxide, hydrocarbons, and nitrogen oxides, into less harmful emissions like carbon dioxide and nitrogen.

The catalytic converter uses chemical reactions facilitated by catalysts, which are materials that promote or speed up these reactions without being consumed in the process. By doing so, it plays a crucial role in meeting environmental regulations aimed at minimizing air pollution from vehicles.

While it can have indirect effects on fuel efficiency and engine performance, those are not its primary function. The main goal is to break down harmful emissions, making option B the accurate choice regarding the purpose of a catalytic converter.
