    • A method of measuring a valve play in a reciprocating valve. The valve has open and closed positions and is operated by an electromagnetic actuator which includes an opening electromagnet, a closing electromagnet, an armature movable between pole faces by electromagnetic forces against a spring force of a return spring arrangement for moving the valve into an open position. The valve play is defined by a clearance between the armature and the valve when the armature is in contact with the pole face of the closing magnet and the valve is in the closed position. The method includes the steps of detecting a motion of the armature within the clearance as a function of the course of voltage and/or current in the closing electromagnet; and deriving the size of the valve play from an irregularity (spike) in the course of voltage and/or current. The irregularity is caused by an impacting of the armature on the valve and/or the pole face of the closing electromagnet.

    • A method of operating a cylinder valve of an internal-combustion engine with an electromagnetic actuator for moving the cylinder valve into opposite open and closed valve end positions includes the steps of energizing an electromagnet of the actuator for generating an electromagnetic force for moving an armature of the actuator toward a pole face of the electromagnet against the force of a return spring; after the armature enters a zone adjacent the pole face of the electromagnet, applying to the armature an additional force opposing the electromagnetic force of the electromagnet; dimensioning the additional force such that an equilibrium between the electromagnetic force of the electromagnet and the increased opposing force of the return spring is situated at a location shortly before the armature enters into engagement with the pole face of the electromagnet; and after the armature reaches the location of force equilibrium, controlling a current supply to the electromagnet such that the armature reaches the pole face of the electromagnet with a predeterminable velocity.

    • A method of initiating motion of at least one of cylinder valve of a cylinder of a reciprocating engine, with each cylinder valve being actuated by an electromagnetic actuator having an electrical closing magnet and an electrical opening magnet, between which magnets an armature that is connected to the cylinder valve to be actuated is movably guided back and forth, counter to the forces of restoring springs, and with the alternating current supply to the closing magnet and the opening magnet being controlled by an electrical engine control. The natural frequency of the spring-mass system formed by the restoring springs and the armature with the cylinder valve is stored in the electrical engine control. The instantaneous rpm and position of the crankshaft with respect to a dead center point position and with reference to the stored natural frequency are detected by the engine control. The time for the beginning of an alternating current supply to the electromagnets is calculated in the period of the natural frequency, taking into consideration the crankshaft rpm and position, the natural frequency of the spring-mass system and the armature path from an inoperative position until it is in contact with the pole surface of one of the two electromagnets, so that the armature motion and the piston motion occur in the same direction immediately before a possible contact of the armature with the pole surface of a capturing magnet.
