ABSTRACT:
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.
