Abstract

A method for regulating a common rail injector, the method including acquiring a signal of a sensor, which signal is proportional to a pressure in a valve space of the common rail injector; evaluating a change in the signal over time in order to detect at least one operating event of the common rail injector; and modifying at least one operating variable of the common rail injector as a function of the at least one operating event, the at least one operating variable being selected from an opening duration, a closing duration, an opening point in time, and a closing point in time of a switching valve of the common rail injector, and from an opening duration, an opening point in time, and a closing point in time of a needle valve of the common rail injector.
