  • Method and control device for operating an internal combustion engine
    Patent number: 8851052
    Abstract: In a method for controlling operation of an internal combustion engine using a control device, a setpoint value of a first fuel injection quantity is specified for a first combustion cycle, and the first fuel injection quantity is injected. A combustion pressure is ascertained during the first combustion cycle, and in a further step, a setpoint value of a second fuel injection quantity is ascertained for a second combustion cycle based on the combustion pressure.

  • Method and device for detecting the fuel quality in an internal combustion engine
    Publication number: 20080228379
    Abstract: A device and a method for detecting the fuel quality in an internal combustion engine, especially a Diesel internal combustion engine. At particular operating states, in at least one cylinder, a start of injection is changed based on a starting value, and it is checked whether combustion takes place. Based on whether a combustion takes place or not, a combustion limit is ascertained and used as a measure for the quality of the fuel.

  • Method and device for operating an internal combustion engine
    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.

  • 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.
