Where is the camshaft?

Where is the camshaft? Pump camshaft manufacturers for you to introduce it:

Camshaft position has a lower - set, in - set and on - set three. The camshaft of the lower type air distribution mechanism is located in the crankcase, the camshaft of the middle type air distribution mechanism is located in the upper part of the body, and the camshaft of the upper type air distribution mechanism is located on the cylinder head.

Most of today's mass-produced cars are powered by overhead camshafts. The main advantages of the overhead camshaft structure are fewer moving parts, short transmission chain and large stiffness of the whole mechanism, which makes the camshaft closer to the valve and reduces the waste of kinetic energy caused by the large distance between the camshaft and the valve. The overhead camshaft engine operates more smoothly at higher speeds because the valves open and close more quickly.
