What are the key components of the Audi 80's engine?

I am trying to understand the inner workings of an Audi 80 and would like to know the main parts of its engine and how they function together.

The Audi 80's engine is comprised of several key components including the crankshaft, pistons, rods, and camshaft. These parts work together to convert fuel into power for the vehicle.

In addition to the main components, the Audi 80's engine also includes an oil pump, timing belt, and spark plugs. These parts play important roles in keeping the engine running smoothly and efficiently.
