- Camshaft - Wikipedia
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion Camshafts are used in piston engines (to operate the intake and exhaust valves), [1][2] mechanically controlled ignition systems and early electric motor speed controllers

What Is a Camshaft? The camshaft regulates the timing of the engine’s valves, controlling when the intake and exhaust valves open and close As the camshaft rotates, it pushes against rocker arms or lifters, opening the valves at precisely the right moments during the engine’s four-stroke cycle

The camshaft is a cylindrical shaft with cams that controls the opening of intake and exhaust valves of the engine The intake cams on the camshaft control the intake valves while the exhaust cams control the exhaust valves

Put simply, the basic purpose of the camshaft is to open and close the valves that control airflow into and out of the combustion chamber When, how much, and for how long is determined by the profile of the cam lobes
