The camshaft is a component in a piston engine. Its function is to control the opening and closing actions of the valve. Although the speed of the camshaft in a four stroke engine is half that of the crankshaft (in a two-stroke engine, the speed of the camshaft is the same as the crankshaft), its speed is usually still very high and it needs to withstand a large amount of torque. Therefore, the design requires high strength and support for the camshaft, which is generally made of high-quality alloy steel or alloy steel. Due to the fact that the valve motion law is related to the power and operating characteristics of an engine, camshaft design plays a very important role in the design process of the engine.
