Abstract (en)
[origin: WO2016173689A1] A method for detecting continuous injection during the operation of an internal combustion engine (1) with an injection system (3) having a high-pressure accumulator (13) for a fuel is proposed, wherein – a high pressure in the injection system (3) is monitored as a function of time, wherein – in order to detect continuous injection it is checked whether the high pressure has dropped by a predetermined continuous injection differential pressure value (App) within a predetermined continuous injection time interval (At^), wherein – it is checked whether a reduction valve which connects the high-pressure accumulator (13) to a fuel reservoir (7) has been triggered, wherein – continuous injection is detected if – a reduction valve has not been triggered in a predetermined checking time interval (ΔΪΜ) before the dropping of the high pressure, and if – the high pressure has dropped by the predetermined continuous injection differential value amount (App) within the predetermined continuous injection time interval (Ati).
