Method for detecting a continuous injection during operation of an internal combustion engine, injection system for an internal combustion engine and internal combustion engine

摘要

The invention relates to a method for detecting a continuous injection during operation of an internal combustion engine (1) with an injection system (3) having a high-pressure accumulator (13) for a fuel, wherein - a high pressure in the injection system (3) is monitored in a time-dependent manner, wherein - for detecting a continuous injection is checked, whether the high pressure within a predetermined continuous injection time interval (.DELTA.tL) by a predetermined continuous injection differential pressure amount (.DELTA.pP) has fallen, wherein - is checked whether a high pressure accumulator (13) with a fuel reservoir (7) connecting Absteuerventil has addressed, wherein - a permanent injection is detected when - in a predetermined test time interval (.DELTA.tM) before the fall of the high pressure has not addressed a Absteuerventil, and if - the high pressure within the predetermined continuous injection time interval (.DELTA.tL) by the predetermined continuous injection Differential pressure amount (ΔpP) has fallen ,
