Energy measurement in the electronic controllers of automotive valves

One way to reduce fuel consumption is the use of control valves in the cylinder. The Time control of the valves can determine the character of the moving car and increases the output power of the engine. The conventional mechanical and hydraulic systems are not able to establish an adaptation time between motor and the instantaneous car situations. A perfect time adaptation between valves and instantaneous moving car is only possible with separate control of each valve. All controllers with sensor have either a technical problem or economically not affordable. Hence the sensorless method has been motivated which is more flexible and free from the cumbersome calculations. The new intelligent valve works with electromagnetic force and is known as electromagnetic valve. It consist of two winding conductor with ferromagnetic cores that are located opposite to each other. This windings ferromagnetic core makes an Electrical - mechanical resonance system that provides the movement of the valves in the cylinder. In this paper, the electronic controller of the electromagnetic valve analysis and energy measurement circuit is designed, fabricated and tested.
