Abstract (en)
[origin: WO2019057666A1] The invention relates to a method for operating an internal combustion engine (1) having an injection system (3) having a high-pressure accumulator (13), wherein an instantaneous high pressure (pl) in the high-pressure accumulator (13) is monitored in a time-dependent manner by means of a high-pressure sensor (23). According to the invention, a first alarm stage (A1) is set, if a) a first predetermined high-pressure limit value (pL1) is exceeded without interruption by the instantaneous high pressure (pi) for a predetermined limit time period (∆tL), and/or b) if the first predetermined high pressure limit value (pL1) is exceeded for the first time at a predetermined, first limit frequency (HL1) by the instantaneous high pressure (p(l).
