Abstract

The fuel injector (1) has a displacement device, which carries out opening and closing motion in a movement axis (2). A measuring device (5) is formed as an inductive sensor and the measuring body, partly surrounds a displacement device in the area of a geometry modification formed in movement direction in order to receive an end of the injector in the combustion chamber (4) or the end stop of the opening stroke. An independent claim is also included for a method for detecting an end of injector of fuel into a combustion chamber.
