  • Method for determining a rail pressure setpoint value
    Patent number: 8096284
    Abstract: In a method for determining a rail pressure setpoint value for a high-pressure rail of an internal combustion engine, the rail pressure setpoint value is modified to a maximum degree using a maximum gradient for changing the rail pressure setpoint value, and the maximum gradient is read from a characteristics map as a function of operating parameters of the internal combustion engine. The operating parameters include an engaged gear of a gear-change transmission.

  • 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.
