摘要： A method for controlling an electromagnetic actuator for actuating a cylinder valve (6) in a piston-type internal-combustion engine, with the valve having two electromagnets (1, 2) that are spaced from one another, and an armature (5) that is connected to the cylinder valve (6) to be actuated and is guided back and forth, counter to the force of a restoring spring (7, 8), between the facing magnet pole faces of the electromagnets, and with the coils (10, 11) of the electromagnets alternately being acted upon with a direct current via a control device (9) at predetermined intervals. When the piston-type internal-combustion engine is operated under a higher load, the flow direction of the current through the coils (10, 11) of the two electromagnets (1, 2) is preset by the control device (9) so that the magnetic flux (arrows 14, 15) alternately effected in the armature (5) by the two coils (10, 11) remains unidirectional. For low-load operation (idling mode) of the engine, the magnetic flux is altered by the repolarization of the flow direction of the current through one of the coils (10, 11), so that the magnetic flux effected in the armature (5) alternately flows in opposite directions (arrows 14.1, 15.1) when the coils are supplied with current.

摘要： A method for monitoring the operation of a piston-type internal combustion engine, comprising electromagnetic actuators with filly variable actuation for the cylinder valves, wherein the engine control unit supplies current based on respective predetermined current flows. The actuators are associated with respective sensors for detecting operation and transmitting operationally relevant signals to the engine control unit of the displacement movement of the respective actuator. The engine control unit detects the current and voltage flows for the actuator and, if no sensor signal is received, a sensor failure or actuator failure is detected from the voltage flow at the actuator. If a sensor fails at the actuator, the detection of a sensor signal is taken from a different, corresponding actuator by the engine control unit and the engine control unit causes initiation of a starting operation (start of oscillations) for the actuator initially determined to be non-operative. If an actuator failure subsequently is detected, the associated cylinder is shut down.
