Abstract
A fuel injection arrangement admits a flow of hydrogen into a combustion chamber of hydrogen internal combustion engine. The fuel injection arrangement has a nozzle cap and an inlet valve arrangement. An inner surface of the nozzle cap comprises a nozzle protrusion protruding radially towards an envelope surface of a flow guiding portion of the inlet valve arrangement. The nozzle protrusion is arranged axially between a valve protrusion of the inlet valve arrangement and an outlet of the nozzle cap. The valve protrusion and the nozzle protrusion at least partly overlap in a radial direction.
