What is the primary goal of using catalytic converters in vehicles?

The primary goal of using catalytic converters in vehicles is to minimize harmful emissions. Catalytic converters are devices that convert toxic pollutants in exhaust gases, such as carbon monoxide, hydrocarbons, and nitrogen oxides, into less harmful substances like carbon dioxide and nitrogen. This conversion process significantly reduces the environmental impact of vehicle emissions, contributing to cleaner air and helping meet regulatory standards for air quality.

In the context of the choices, while increasing fuel consumption and enhancing vehicle speed do not align with the purpose of catalytic converters, lowering operating costs can be a secondary benefit resulting from greater fuel efficiency and reduced emissions. However, the foremost function of catalytic converters remains their role in reducing harmful emissions, which is crucial for environmental protection and public health.
