Abstract

An injection nozzle for the direct injection of a liquid fuel into a cylinder chamber of a piston engine includes multiple spray holes for generating injection jets. The multiple spray holes are distributed on a nozzle body of the injection nozzle in the peripheral direction. At least one pair of spray holes adjoining in the peripheral direction is provided, the longitudinal center axes of which enclose a pair angle in the peripheral direction that is smaller than an adjacent angle which is enclosed between the longitudinal center axis of the respective spray hole of the spray hole pair in the peripheral direction and a longitudinal center axis of a spray hole adjoining the spray hole pair in the peripheral direction.
