Abstract (en)
[origin: US2011166803A1] 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.
