[0002] A camshaft is a component in a piston engine. Its function is to control the opening and closing actions of the valves. Although the rotational speed of the camshaft in a four-stroke engine is half of that of the crankshaft, generally its rotational speed is still very high and it needs to bear a large torque. Therefore, in the design, the requirements for the camshaft in terms of strength and support are very high, and its material is generally high-quality alloy steel or alloy steel. Since the valve motion law is related to the power and operating characteristics of an engine, the camshaft design occupies a very important position in the engine design process.
