Abstract:
A fuel injection nozzle which injects fuel onto a combustion space of an internal combustion engine, configured to be surrounded in a nozzle receptacle located on the same side as the internal combustion engine and to be open towards the combustion space, comprising a nozzle body, a nozzle neck offset to the nozzle body, an injection orifice arranged at an end of the neck located on a combustion-space side, a shielding sleeve radially overlapping the nozzle neck to delimit an annular gap relative to the nozzle neck and, with the nozzle in a mounting position, to define a radial clearance relative to the surrounding nozzle receptacle, the nozzle being insertable into the nozzle receptacle in a direction of the combustion space and, with the nozzle in the mounted position, the shielding sleeve being axially clamped, and an annular collar provided at an end thereof facing the nozzle body, between the nozzle body and nozzle receptacle in a region of the beginning of the neck, wherein, in relation to the mounting position of the nozzle, the shielding sleeve has, in an axial region extending toward the annular collar, an outer contour which, at least over a circumferential portion thereof, radially undercuts an inner contour of the nozzle receptacle in an axial region offset in the direction of the combustion space, wherein the axial region having the outer contour is separate from the annular collar.
