Fuel injector for operation with combustible gas

A fuel injector for operation with combustible gas, comprising:

• at a nozzle end, a gas nozzle assembly having at least one gas nozzle opening;
• at least one gas nozzle needle assigned to the gas nozzle assembly and accommodated in an axial holder so that a stroke of the needle is controllable, wherein each gas nozzle opening leads out of the holder at the nozzle end with a radial direction component;
• and
• a needle seat arranged in the holder upstream of the respective gas nozzle opening, the needle seat being provided for selectively blocking, in cooperation with the gas nozzle needle, a combustible gas flow path to the respective gas nozzle opening, wherein the at least one gas nozzle opening is distributed merely over part of a circumference in a circumferential direction of the gas nozzle needle, wherein the holder, adjoining the needle seat and extending axially away therefrom in an upstream direction, is formed asymmetrically with respect to an axial center axis through the gas nozzle needle, wherein the asymmetry results from a cross-section widening of the holder on a side of the holder lying radially opposite the at least one gas nozzle opening, such that the cross-section widening permits a greater mass flow of combustible gas in the holder than on a gas nozzle opening side opposite thereto, wherein the holder is also configured to apply a flow direction, oriented towards a radially opposite at least one gas nozzle opening, upstream of the needle seat and by way of the cross-section widening, to a combustible gas flow guided to the needle seat by the cross-section widening.
