Audi valvelift system

The AVS principle: Pins engage in the cam elements and move them along the camshaft. In the illustration the high, "acute" cam (red) is active.
High efficiency: When the cam element moves to the left, the low cam (green) comes into play. It operates the valves with a small lift.
