What is the purpose of a catalytic converter?

I am wondering what the role of a catalytic converter is in my Audi A1. Can you provide some insight?

The catalytic converter helps reduce emissions of harmful gases from your car's exhaust. It converts these gases into less harmful substances before they are released into the environment.

Your Audi A1's catalytic converter is an important part of maintaining a clean and efficient engine. It works by converting harmful pollutants into less harmful byproducts, reducing the impact of your car on the environment.

Having a functioning catalytic converter is not only important for the environment, but also for the performance of your car. A damaged converter can cause issues with your engine and decrease fuel efficiency.
