摘要： A method for operating a piston-type internal-combustion engine having electromagnetic valve trains for actuating the cylinder valves, which respectively have an armature that can move back and forth between two electromagnets, counter to the force of restoring springs, with the valves being completely variably actuated by an electronic engine timing control unit. The functioning of the electromagnetic valve trains of each cylinder is detected in the engine timing control unit during operation, and when a functional failure of an electromagnetic valve train is detected at a cylinder, the electromagnet of the failed electromagnetic valve train is acted upon with a capturing current, which brings the armature into an end position at an electromagnet, and from this end position, the electromagnetic valve train is actuated for the ongoing work cycle of the cylinder.

摘要： A method for controlling an electromagnetic actuator operating a gas exchange valve in an internal combustion piston engine. Between two electromagnets an armature, connected to the gas exchange valve, is reciprocated by a return spring between the electromagnets whose alternating energization moves the valve into open and closed positions. The lift of the armature is detected by a sensor array during its movement from one pole face to the other. Depending on the detected actual values of the armature lift, the energy flow to the electromagnets is controlled such that the armature moves at a speed tending to zero at a predetermined distance range from the pole face of the capturing electromagnet. At the end of the lift motion, the current flow through the capturing electromagnet is guided in such a way that the armature is maintained oscillating at a short distance from the pole face of the capturing electromagnet.

摘要： The invention relates to a method for controlling an electromagnetic actuator for activating a gas exchange valve on a reciprocating internal combustion engine, said gas exchange valve having two electromagnets that are set apart from each other and between which an armature that acts on the gas exchange valve against the force of at least one return spring is guided in such a way that it can move back and forth between the pole faces of the two electromagnets. The electromagnets are alternately subjected to a receiving current by means of a control unit and the movement of the armature on its path from one pole face to the other is detected by means of a sensor unit. Actual values relating to the movement of the armature are detected by the sensor unit in a first phase (I) beginning with the start of the release of the armature from the pole face of the holding electromagnet; the receiving electromagnet is controlled by the control unit in terms of the supply of current, according to the detected actual values relating to the movement of the armature, in a second phase (II), in such a way that the armature moves at a predetermined speed and with an acceleration around zero, within a predetermined range away from the pole face of the receiving electromagnet; and in a third phase (III), the supply of current of the receiving electromagnet is influenced in such a way that the armature meets the pole face at a predetermined minimum speed.
