ABSTRACT:
A fuel injection nozzle is proposed, in which an inner nozzle needle and an outer nozzle needle can be actuated independently of one another. Upon opening of the outer nozzle needle, a stream of fuel is injected into the combustion chamber in the direction of the longitudinal axis of the fuel injection nozzle, while upon opening of the inner nozzle needle, the fuel is injected laterally into the combustion chamber.
