    摘要： A combination of a cylinder valve of an internal-combustion engine with an electromagnetic assembly for operating the valve. The electromagnetic assembly includes an electromagnetic actuator having first and second electromagnets supported in a spaced relationship with respect to one another, an armature movable between the first and second electromagnets and connected to the valve for moving it between open and closed positions. The electromagnetic assembly further includes a first control device for energizing the electromagnets to cause a motion of the valve by electromagnetic forces generated by the first and second electromagnets; and first and second pressurizable resetting gas springs operatively coupled to the armature to oppose motions thereof caused by the electromagnetic forces generated by the first and second electromagnets, respectively. A pressure supply device supplies pressure to the first and second resetting gas springs. A second control device controls the pressure supplied to the first and second resetting gas springs.

    摘要： 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.

    摘要： A method of operating an electromagnetic actuator for actuating a setting member wherein the actuator includes at least one electromagnet supplied with current by a control device, and an armature that is operatively connected with the setting member to be actuated and which can be brought out of a first set position, counter to a force of a restoring spring, into a second set position, in which the armature is in contact with the pole face of the electromagnet, when the electromagnet is supplied with current. The change in the setting force of the restoring spring is detected, at least during part of the armature motion, and the respective position of the armature and/or its moving speed is or are derived from this. The derived value is used to check and/or influence the actuation of the electromagnet.

    摘要： A process is disclosed for controlling a multiple cylinder internal combustion engine in which exhaust gases undergo subsequent treatment. To ensure a gaseous exchange, air is supplied to the individual cylinders through inlet devices and exhaust gases are discharged through outlet or exhaust devices. The inlet and outlet devices are independently driven but their opening and closing times may be synchronized. Beginning in the cold start phase until the warming up phase, fuel is supplied to only part of the cylinders that act as an engine and the supply of fuel to the other cylinders is cut off. The other cylinders work then as compressors. The air volume heated in these cylinders by compression flows through the outlet device into the exhaust gas system and reacts with the exhaust gases.

    摘要： 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.
