    • A method for actuating an electromagnetic actuator for a cylinder (gas exchange) valve of a piston-type internal combustion engine, wherein the actuator has two spaced electromagnets and an armature which is operatively connected to the cylinder valve and which is guided movably, as a function of the current supplied to the electromagnet by a control unit, in the closing direction counter to the force of an opener spring and in the opening position counter to the force of a closing spring, and for the normal stroke of the gas exchange valve, the armature is kept via the springs at the same spacing from the two electromagnets when the electromagnets are without current. To shorten the valve stroke during operation, the prestressing of one of the two springs, preferably the opener spring, is variable via an adjusting device which is triggered or controlled via the engine control unit.

    • An electromagnetic actuator operating a cylinder valve of an internal-combustion engine includes first and second spaced electromagnets having pole faces oriented toward one another; an armature arranged for reciprocating motion between the pole faces; and a connecting rod having a first rod part being in an abutting contact with a first side of the armature and being a component separate therefrom. The abutting contact is such as to prevent a torque transmission between the first rod part and the armature. The connecting rod has a second rod part which is rigidly affixed to a second side of the armature and extending towards the cylinder valve. There are further provided a first spring situated adjacent the first electromagnet externally thereof and arranged for urging the first rod part into the abutting contact with the armature for urging the armature away from the first pole face towards the second pole face; and a second spring situated adjacent the second electromagnet externally thereof and arranged for urging the armature away from the second pole face towards the first pole face. The first and second springs act oppositely such that in a de-energized state of the first and second electromagnets the armature is held by the first and second springs in an intermediate position between the pole faces of the first and second electromagnets.

    • A four-stroke Otto engine. At least two intake valves of the engine have an open position and a closed position, and include a main intake valve and an additional intake valve. A camshaft moves the main intake valve into its open position and into its closed position, and a transmission element transmits a motion of the camshaft to the main intake valve. The transmission element includes a cutoff apparatus actuatable independently of the camshaft for cutting off a transmission of the actuation of the camshaft to the main intake valve for keeping the main intake valve in its closed position in a lower partial load and rpm range of the engine. An operating apparatus connected to the additional intake valve actuates the additional intake valve independently of the actuation of the main intake valve for moving the additional intake valve into its open position in a lower partial load and rpm range of the engine and into its closed position in an upper partial load and rpm range of the engine. The operating apparatus further adjusts at least one of a valve stroke of the additional intake valve, a valve opening time of the additional intake valve and a valve closing time of the additional intake valve as a function of engine load. An intake control device controls the cutoff apparatus and the operating apparatus.
