Abstract (en)

[origin: WO2020187802A1] The invention relates to a method for operating an internal combustion engine (1), which has an injection system (3), which comprises a high-pressure accumulator (13) for a fuel, wherein: - a high pressure in the injection system (3) is monitored over time; - at a high-pressure-dependent starting time, it is checked whether continuous injection detection should be performed, by examining whether a high-pressure oscillation has occurred within an oscillation time interval (ΔtL,O) before the starting time.
