  • Patent number: 6101992
    Abstract: An electromagnetic actuator includes an electromagnet having a pole face, an energized state for generating an electromagnetic force and a de-energized state; and an armature movable towards and away from the pole face in a travel path extending from a first end position remote from the pole face to a second end position at the pole face. The armature assumes the second end position in the energized state of the electromagnet. A return spring urges the armature away from the pole face and toward the first end position. Further, a fluid damping unit is provided for braking a motion of the armature along a terminal portion of its travel path shortly before its arrival into at least one of the end positions for effecting a soft arrival of the armature into such end position.

  • Patent number: 6041667
    Abstract: 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.

  • Patent number: 5930992
    Abstract: 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.
