What is the role of a catalytic converter?

The role of a catalytic converter is primarily to reduce harmful emissions from the exhaust. It achieves this by facilitating chemical reactions that convert toxic gases produced during combustion, such as carbon monoxide, nitrogen oxides, and unburned hydrocarbons, into less harmful substances like carbon dioxide and nitrogen. This process is essential for meeting environmental regulations and improving air quality.

The catalytic converter operates at high temperatures and utilizes catalysts, typically a combination of platinum, palladium, and rhodium, to accelerate these reactions without being consumed in the process. By effectively reducing these emissions, the catalytic converter plays a vital role in keeping vehicle operation within legal limits regarding pollutants and contributing to overall environmental protection.
