  • Patent number: 10451009
    Abstract: A method for knock control of an internal combustion engine capable of being operated using a water injection system, in which at least one parameter of the knock control is determined as a function of a variable connected to the water injection system, in particular the water content.
    Type: Grant

  • Patent number: 8571784
    Abstract: A method for controlling a fuel injector of a diesel engine having a predefined control time from a control start, in which a setpoint value of a combustion start of a combustion chamber charge of the diesel engine is ascertained. The method is characterized in that an ignition delay between the control start and the combustion start is estimated from performance parameters of the diesel engine using a computing model, and the control start is formed on the basis of the setpoint value of the combustion start and the estimated ignition delay. A control unit controls the sequence of the method.

  • Patent number: 7337059
    Abstract: A method and a device for controlling an internal combustion engine. In a first operating mode, a fuel quantity is predefined according to a first rule for calculating the quantity based on at least the torque variable. In a second operating mode, the fuel quantity is predefined according to a second rule for calculating the quantity based on at least the torque variable. A control variable is predefined on the basis of at least the torque variable.

  • Patent number: 7257479
    Abstract: A method and a device for controlling an internal combustion engine are provided, in which method and device a deviation value is determined based on the comparison of a variable characterizing the combustion process in at least one cylinder with a corresponding setpoint value for this variable. Based on the determined deviation value, a first manipulated variable of a first actuator for influencing the start of activation is adjusted. Furthermore, based on the first manipulated variable, a second manipulated variable of a second actuator for influencing the air mass is adjusted.

  • 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.
