A fuel gas injection arrangement and a hydrogen internal combustion engine

A fuel gas injection arrangement for directly injecting a gaseous fuel into a combustion chamber of an internal combustion engine, the fuel gas injection arrangement extending in an axial direction and comprising:

• a nozzle cap having a body part with an inner circumferential side at least partly defining an inner volume, an inlet for receiving gaseous fuel and at least one outlet arranged at an axial end portion of the nozzle cap;
• an inlet valve arrangement at least partly accommodated in the body part, the inlet valve arrangement being movable between a closed position in which a portion of the inlet valve arrangement is arranged in abutment with a valve seat of the nozzle cap to prevent fuel gas from entering the inlet, and an open position in which the fuel gas is allowed to flow between the inlet and the at least one outlet;
• wherein said nozzle cap further comprises a flow-guiding portion disposed on the inner circumferential side and said inlet valve arrangement comprises a corresponding protruding flow-guiding portion protruding radially towards the inner circumferential side;
• said nozzle cap flow-guiding portion and said valve protruding flow-guiding portion being configured to cooperate to redirect gaseous fuel received from the inlet towards the at least one outlet such that gaseous fuel jets exiting the at least one outlet converge towards a geometrical intersection-axial center region, said geometrical intersection-axial center region being located downstream and axially distanced from said at least one outlet.
