INJECTION NOZZLE FOR A DUAL-FUEL ENGINE, DUAL-FUEL ENGINE AND METHOD FOR OPERATING THE SAME

An injection nozzle that for a first fuel in a first mode and in a second mode ignition fluid for a second fuel is introduced. The injection nozzle includes an injection nozzle body with first and second injection orifices and a displaceable injection nozzle needle in the injection nozzle body. The first injection orifices have smaller injection orifice cross-sections than the second injection orifices and are arranged at a defined distance. In a first displacement direction for closing the orifices the first injection orifices are located in front of the second injection orifices and seen in a second displacement direction of the injection nozzle needle for the opening or unblocking of the orifices, the first injection orifices are located behind the second injection orifices.
