    The camshaft is a component in the piston engine. Its role is to control the opening and closing of the valve. Although in a four-stroke engine, the camshaft rotates at half the speed of the crankshaft (in the two-stroke engine, the camshaft rotates at the same speed as the crankshaft), the speed is usually very high, and it needs to withstand large torques. The camshaft has high requirements in terms of strength and support, and its material is generally high-quality alloy steel or alloy steel. Because the valve movement law relates to the power and running characteristics of an engine, the camshaft design occupies a very important position in the engine design process.
