Abstract:
A fuel injection nozzle which injects into a combustion space of an internal combustion engine and which is arranged in a nozzle receptacle located on the same side as the internal combustion engine and opens towards the combustion space, comprising a nozzle body, and a nozzle neck stepped relative to the nozzle body, an injection orifice arranged at an end of the neck located on the combustion-space side so as to be associated, in a neck region, with a shielding sleeve located radially on an outside with a clearance relative to the surrounding nozzle receptacle and, starting from one end thereof, to bear radially on an inside of the neck without any play via one axial region and, via another region, to delimit relative to the neck an annular gap and provided, at an end thereof facing the nozzle body, with an annular collar being clampable in a region of the neck starting between the nozzle body and the nozzle receptacle, wherein the shielding sleeve has radially play-free bearing contact on the end region of the nozzle neck which is located on the combustion-space side, and the annular gap between the shielding sleeve and the nozzle neck is closed off as a result of the bearing contact between the nozzle neck and the shielding sleeve, and the bearing contact of the annular collar, located axially at a transition of the nozzle neck and the nozzle body, on the nozzle body.
