Abstract
The invention relates to a control chamber, the pressure of which determines the strokes or positions of a nozzle needle, and which is assigned to a force or pressure sensor in order to detect the progression of the control chamber pressure. Because the control chamber pressure significantly changes during the closing of the nozzle needle, the operating phases of the injector can be exactly determined from the sensor data and supplied to an engine controller.
