Abstract

A nozzle cap for a fuel gas injection arrangement of an internal combustion engine has: a body part defining an inner volume for accommodating a part of a movable valve arrangement, an inlet for receiving gaseous fuel, and at least one outlet arranged at an axial end portion of the nozzle cap. The at least one outlet permits discharge of one or more gas jets of fuel into a combustion chamber of the internal combustion engine. The axial end portion of the nozzle cap has a radial protrusion extending from an inner side of the nozzle cap towards an axial center axis and is delimited in a circumferential direction by axially-extending side sections, said radial protrusion having an inner surface region for reducing a crossflow of the fuel gas flow inside the nozzle cap and guiding said fuel gas flow towards the at least one outlet.
