How does the Audi internal combustion engine work?

I recently purchased an Audi and I am curious about how the engine operates. Can someone provide an explanation of the inner workings of the Audi internal combustion engine?

The Audi internal combustion engine works by converting fuel into energy through a series of controlled explosions. This energy is then used to power the vehicle. It is a complex system that involves precise timing and a carefully designed combustion chamber.
