| Zusammenfassung: | A fuel injection system for an internal combustion engine in which pressurized fuel is made available in a pressure accumulator and a fuel pressure prevailing in the pressure accumulator is ascertained with the aid of a pressure sensor and in which the fuel enters a combustion chamber of the internal combustion engine through at least one fuel injection device. A slope of a curve, which links a pressure difference in the pressure accumulator during a fuel injection to an injected fuel quantity, is ascertained and the fuel pressure prevailing in the pressure accumulator is inferred from the slope. |
