Fabrication of Cam less engine

In this modern world where companies are focusing on green energy,cam less engine can become a great alternative.

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. In an engine, it is connected to a shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.

In traditional engine camshaft has a very important role to play while opening and closing of a valve. It was a necessary evil for an engine functioning.Furthermore, because of camshaft, engineers need to choose either efficient engine or power engine but not with both qualities.This is one of the most important factor that makes camless engine a necessity. Though , idea of cam less engine existed from 1899,it has become need of modern world now, when we need power and efficiency both.
A camless engine uses electromagnetic, hydraulic, or pneumatic actuators to open the poppet valves instead. Actuators can be used to both open and close the valves, or an actuator opens the valve while a spring closes it.An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion.
