Camshaft basics
WebFeb 3, 2024 · The basic function of a camshaft (or just cam for short) is to turn rotating motion into linear motion. Driven by the crankshaft, the cam spins half as fast. So when the crank is spinning at 3,000 RPM, the cam is spinning at 1,500 RPM. This allows the 4-stroke action to take place inside the engine. Each rotation of the cam provides the opening ...
