Abstract:
A method for monitoring the condition of a piezoinjector of a fuel injection system is disclosed. The fuel injection is carried out in injection cycles, each of which comprises a filling phase, a holding phase, and an emptying phase. The discharge resistance is ascertained during the holding phase of the piezoinjector. Conclusions about the working order of the piezoinjector are drawn using the ascertained discharge resistance.
