  • Method for actuating an electromagnetic valve, and corresponding fluid system
    Patent number: 10593458
    Abstract: A method for actuating an electromagnetic valve in a fluid system includes, for a specified first time period, a switching current with a specified first amplitude is applied, the switching current switching the electromagnetic valve from a rest state into a switching state. After the specified first time period expires, a holding current with a specified second amplitude is applied, the holding current holding the electromagnetic valve in the switching state. The first amplitude of the first switching current is greater than the second amplitude of the holding current.
    Type: Grant

  • Method and device for controlling an internal combustion engine
    Patent number: 7216029
    Abstract: A method and a device for controlling an internal combustion engine. The air quantity supplied to the internal combustion engine is controllable by a first actuator, and/or the fuel quantity supplied to the internal combustion engine is controllable by a second actuator in at least two operating modes. The operating mode is processed as a function of its assigned priority, this priority being predefinable.
