- the twist can thus be determined with regard to its characteristics by the choice of the size, the arrangement and the configuration of the tangential and axial bores with respect to one another.
- the atomizer nozzle preferably has an internal cross section which has a pressure profile over its course which, at least directly around an outlet opening of the fuel from a fuel supply, shows a value which is lower than the pressure prevailing in the fuel supply.
