Abstract:
The disclosure relates to a control method for controlling at least one injector valve in a fuel injection system of an internal combustion engine. An opening time of the injector valve is selected such that, in a fault situation in the fuel injection system, an opening time of the injector valve is situated in a pressure valley of a pressure oscillation prevailing in a high-pressure region of the fuel injection system.

Claim (Index 1):
A control method for controlling at least one injector valve in a fuel injection system of an internal combustion engine, the method comprising:\n providing a fuel injection system including:\n a high-pressure fuel pump with a pump piston which is movable between a bottom dead center (BDC) and a top dead center (TDC) in a pressure chamber during operation and which serves for highly pressurizing a fuel, and \n a high-pressure region for storing the highly pressurized fuel and for supplying the highly pressurized fuel to the at least one injector valve; \n providing a pressure-limiting valve which, when a predefined opening pressure is reached in the high-pressure region, discharges fuel from the high-pressure region into the pressure chamber of the high-pressure fuel pump; detecting a fault situation in the fuel injection system, wherein the predefined opening pressure is overshot in the high-pressure region; detecting TDC times at which the pump piston is situated at the top dead center, and determining a period duration with four evenly distributed quadrants between a first TDC time and a second TDC time; and controlling the injector valve such that an opening time of the injector valve lies in an opening duration which extends in a second quadrant of the period duration and/or in a third quadrant of the period duration.
