How does the turbocharged engine in the Audi A1 work?

I've heard that the Audi A1 has a turbocharged engine, but I'm not sure how it actually works. Can someone explain it to me?

The turbocharged engine in the Audi A1 uses a combination of exhaust gases and a small turbine to compress the incoming air, resulting in more power and better fuel efficiency.

Think of the turbocharger as a mini jet engine for your car. It uses a turbine to compress air and increase the amount of air and fuel mixture in the engine, which produces more power during combustion.
