  • METHOD AND DEVICE FOR OPERATING A FUEL INJECTION SYSTEM
    Publication number: 20130167809
    Abstract: In a method for operating a fuel injection system for an internal combustion engine of a motor vehicle, an output signal of a pressure sensor which characterizes a fuel pressure in a pressure accumulator is evaluated. An undesirably high fuel pressure in the pressure accumulator and/or a fault in the fuel injection system is/are inferred at the time when the output signal assumes a maximally possible value for at least a predefinable monitoring period.

  • Method and Device For Controlling an Internal Combustion Engine
    Publication number: 20120004822
    Abstract: A method and a device for controlling an internal combustion engine are described. At least one injector meters a certain fuel quantity to the internal combustion engine at a certain point in time on the basis of a first signal and/or a second signal. At least the first and/or the second signal is/are corrected using a correction value. The correction value is adapted on the basis of at least one information value which is provided by at least one compensation procedure.

  • METHOD FOR DETERMINING AN OVER-PRESSURE IN A FUEL STORAGE MEANS OF AN INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE
    Publication number: 20110166803
    Abstract: A method for determining an overpressure in a fuel reservoir of an injection system of an internal combustion engine, in particular in a common rail of a common rail system, the pressure in the fuel reservoir being sensed, an overpressure in the fuel reservoir being identified if the derivative of the sensed pressure over time exceeds a predetermined slope threshold value and the sensed pressure then exceeds a predetermined pressure threshold value.
