Abstract
An injection nozzle for diesel engines is disclosed with a direct fuel injection into combustion air in the combustion space having a swirl. The nozzle is constructed as a hole-type nozzle with several injection openings arranged at uniform distances and distributed along the nozzle circumference. In order to further develop such an injection nozzle in a manner which permits shorter injection durations and an improved utilization of the air, an additional injection opening with a smaller diameter is constructed in each case between two adjacent larger injection openings, whereby the overall cross-sectional surface of all injection openings becomes larger without any drifting into one another of the thus formed fuel sprays.
