Abstract (en)
[origin: US6474276B1] A method for controlling an electromagnetic actuator for a cylinder valve in a piston-type internal combustion engine with the actuator being operatively connected to the cylinder valve and moveable back and forth between two electromagnetics, counter to the force of at least one restoring spring. The current supplied to the electromagnetics is controlled with the aid of a sensor arrangement and via an engine control unit such that the current supply to the catching electromagnet, i.e., the electromagnet being approached by the moveable armature of the actuator, is controlled so as to move the armature slowly toward the respective pole face. Moreover, in order to regulate the valve play during the closing movement of a cylinder valve, the current supply to the catching electromagnet is controlled such that the valve initially touches down softly on its seat and that following the valve play, the armature touches down softly on the pole face.
