An automotive tappet, also known as a lifter, is a small but important component of an internal combustion engine. It is a cylindrical shaped device that rests on the camshaft and is responsible for transferring the motion of the camshaft to the engine's valves.
The tappet consists of a body, which houses a hydraulic plunger or a mechanical mechanism, that responds to the rotation of the camshaft and moves up and down, opening and closing the engine's valves in time with the motion of the pistons. The precise operation of the tappet is critical to the proper functioning of the engine, as any malfunction or wear can cause a loss of power, reduced fuel efficiency, and even engine failure.
Automotive Tappets can be found in most internal combustion engines, including those used in cars, trucks, and motorcycles, and are typically made of steel, aluminum, or other durable metals.
