The car camshaft is located inside the engine, that is, the upper part of the engine. The car camshaft is a component in a piston engine. The following camshaft wholesale, camshaft manufacturers and camshaft brand companies will talk about its role:
1. It controls the opening and closing of the valve, although the speed of the camshaft in a four-stroke engine is half the speed of the crankshaft (the camshaft of a two-stroke engine is the same as the crankshaft);
2. But generally its speed is still very high, and it needs to bear a lot of torque, so the design of the camshaft has high requirements on strength and support, and its material is generally special cast iron, and occasionally forgings are used;
3. Since the law of valve motion is related to the power and operating characteristics of the engine, the camshaft design occupies a very important position in the engine design process.
