Method for regulating a common-rail injector

A non-transitory machine-readable storage medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for regulating a common rail injector, by performing the following:
• acquiring a signal of a sensor, the signal being proportional to a pressure in a valve space of the common rail injector;
• evaluating a change in the signal over time 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, wherein the at least one operating variable is selected from at least one of:
• (i) one of:
• 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:
• (i) one of an opening duration, an opening point in time, and a closing point in time of a needle valve of the common rail injector;
• wherein the sensor is disposed in a low-pressure region of the common rail injector, and
• wherein a pressure of a control space also exists in the valve space when a closure element is closed, so that in this valve position, a guidance rod inside the closure element is loaded at the end with a pressure of the control space, so that a valve space pressure is directed via the guidance rod to the sensor.

An electronic control device for regulating a common rail injector, comprising:

• an electronic control unit configured to perform the following:
• acquiring a signal of a sensor, the signal being proportional to a pressure in a valve space of the common rail injector;
• evaluating a change in the signal over time 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, wherein the at least one operating variable is selected from at least one of:
• (i) one of:
• 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:
• (ii) one of an opening duration, an opening point in time, and a closing point in time of a needle valve of the common rail injector;
• wherein the sensor is disposed in a low-pressure region of the common rail injector, and
• wherein a pressure of a control space also exists in the valve space when a closure element is closed, so that in this valve position, a guidance rod inside the closure element is loaded at the end with a pressure of the control space, so that a valve space pressure is directed via the guidance rod to the sensor.
