Abstract
A fuel injection nozzle is proposed, intended in particular for Diesel engines, in which an induction coil is installed in an intermediate disc. The coil core is embodied by a pressure element and a valve needle in force-locking contact therewith. An annular permanent magnet is secured either on the pressure bolt or on the intermediate plate. This embodiment of an injection nozzle, as a so-called needle stroke transducer, is used when it is desired to ascertain the duration of injection and especially the onset of injection.
