Camshaft Is One Of The Piston Engine Parts

Camshaft is one of the piston engine parts. Its role is to control the valve opening and closing action. Although in the four-stroke engine camshaft speed is half of the crankshaft (in two stroke engine camshaft speed is the same as the crankshaft), but usually it's speed is still high, but need to bear a lot of torque, so the design of a high requirement on the camshaft in terms of strength and support, the material is special cast iron, occasionally also have the use of forgings. Due to valve motion is related to an engine power and running properties, so the design in the design process of the engine camshaft occupies very important position.

The main body of the camshaft is a same as the cylinder length cylindrical bar body. The above set of several CAM, used to drive the valve. One end of the camshaft is bearing strong point, the other end connected with the drive wheels.
