Abstract (en)
[origin: EP0661447A1] The present invention relates to an injection nozzle (4) for diesel engines with direct fuel injection into combustion air in the combustion space, to which air a swirl has been imparted. The nozzle is designed as a hole-type nozzle with a plurality of injection openings (8, 9) arranged at uniform intervals around the circumference of the nozzle. In order to develop an injection nozzle (4) of this kind so as to permit shorter injection durations and improved air utilisation, an additional injection opening (9) with a smaller diameter is in each case formed between two adjacent injection openings (8), making the total cross-sectional area of all the injection openings (8, 9) greater without the fuel jets thereby formed being blown into one another. <IMAGE>
