1. An injection nozzle configured for direct injection of a liquid fuel into a cylinder chamber of a spark-ignited piston engine, the injection nozzle comprising:
a nozzle body; and multiple spray holes, each configured for generating injection jets, wherein the multiple spray holes are arranged in a star-shaped pattern and are distributed on the nozzle body in a peripheral direction, wherein at least one pair of spray holes of the multiple spray holes, which are adjoining in the peripheral direction, have longitudinal center axes enclosing a pair angle in the peripheral direction, wherein the pair angle is smaller than an adjacent angle enclosed between the longitudinal center axis of one of the spray holes of the at least spray hole pair in the peripheral direction and a longitudinal center axis of a spray hole of an adjoining the spray hole pair in the peripheral direction, wherein the multiple spray holes include exactly six spray holes, wherein the multiple spray holes include exactly two spray hole pairs that are diametrically opposed; wherein a further spray hole is situated, in the peripheral direction, between each of the at least one pair of spray holes, wherein the injection nozzle is situated in an area of a longitudinal center axis of a cylinder of the cylinder chamber, wherein an ignition device of the cylinder is situated at a distance from the injection nozzle, wherein the injection nozzle is oriented with respect to the multiple spray holes in such a way that the ignition device is situated, in the peripheral direction, between the two injection jets of the at least one pair of spray holes, and wherein the ignition device is situated, in the peripheral direction, between two exhaust valves of the cylinder. |
