We just learned about the Tappet.

Another part of a car is the Valvetrain.

We've learned about the camshaft that spins around with cams on it, that pushes on the intake and exhaust valves for the pistons.

The Valvetrain is the name for all of the valves hooked together on the camshaft, pushing the valves in and out.
