Beschreibung
Zusammenfassung:	The present invention relates to an injection nozzle (3) for the direct injection of a liquid fuel into a cylinder chamber (4) of a piston engine (1), preferably spark-ignited, having a plurality of injection holes (8) for producing injection jets (9), which are arranged distributed on a nozzle body (10) of the injection nozzle (3) in the circumferential direction. Reduced harmful emissions can be achieved when at least one pair (12) of injection holes (8) adjoining in a circumferential direction is provided, the longitudinal centre axes (13) of which include a pair angle (14) in the circumferential direction that is smaller than an adjacent angle (15) which is included in the circumferential direction between the longitudinal centre axis (13) of the respective injection hole (8) of the injection hole pair (12) and a longitudinal centre axis (13) of an injection hole (8) adjacent to the injection hole pair (12) in the circumferential direction.
