Why do we have catalytic converters in cars?

There are millions of cars on our roads, and each one is a source of air pollution. We are aware of the issues caused by pollution from these vehicles, especially in the cities.

To reduce the problem of pollution, manufacturers have made many improvements to car engines and fuel systems. One of these changes came about in 1975 with an interesting device called a catalytic converter.

A catalytic converter is a stainless steel can with a catalyst made of platinum, rhodium and palladium alloys inside. The job of the catalytic convertor is to convert harmful pollutants into less harmful emissions before they leave the car’s exhaust system.

The catalytic converter has a honeycomb surface coated with the catalyst, which converts the polluting gases into less harmful nitrogen, carbon dioxide and water vapour.
