One of the ways to minimize fuel consumption in automobiles is to use cylinder-controlled valves. Traditional mechanical and hydraulic systems cannot achieve a fast time adaptation between the engine and the instantaneous position of the vehicle. With the separate control of each valve in the cylinder, it is possible to fully adjust the timing between the valves and instantaneous movement of the car. Sensor controllers usually have either a technical problem or are not economically viable. So the research of car companies is moving towards replacing the sensorless approach, to avoid overwhelming computation on the one hand, and to be more flexible against interference, on the other. Modern valves that work with electromagnetic force are known as electromagnetic valves. These valves are composed of two coiled inductors with a ferromagnetic core facing each other. This coiled ferromagnetic core creates an electrical-mechanical resonance system that provides the ground for the valves to move in the cylinder. In this article, the electronic controller part of the electromagnetic valve is analyzed, designed, and tested.
