What is?
UK CamconAuto company developed a new type of electrically controlled gas distribution system, can be optimized intake and exhaust of the internal combustion engine.
2
what’s the use?
by a motor for precise independent control of each valve can be more precisely control the intake and exhaust, in addition to controlling the size of the valve opening, the timing, but also allow the valve remain open for a period of time. To improve fuel economy and reduce the effect of emissions.

advantages
eliminating the conventional valve train camshaft, the engine simplification structure, thereby reducing the weight.
uses the engine as compared to a conventional mechanism installed for the smaller size.
This system can accurately control the intake air amount of each cylinder, to improve intake efficiency, to improve the response speed of the engine.
can improve vehicle fuel economy.
to reduce pollutant emissions.

Principle
Top two permanent magnet motor, the motor is connected to a valve corresponding to each a cam shaft small, since each corresponding to a small valve camshaft. Therefore, the valve can be controlled independently of its opening time, the size of the lift. Electrical control means of the engine so that the top can be accurately controlled according to the engine of a real-time state of the valve, to achieve a more efficient operation of the engine. And setting up large and small two cam angle, small angle at low speed cam on the camshaft IVA is still small, enabling a large increase in valve lift of the cam angle, to enhance the intake efficiency at high speeds.
