Abstract (en)
The fuel injector has a staged nozzle in which are controlled two axially installed nozzle needles (20,22). The injector has an inner and an outer control chamber (12,13), with one of the nozzle needles allocated to each. The two control chambers are sealed in relation to one another by a matched upper needle guide (16) of the inner nozzle needle (20), and each control chamber is individually controllable without the influence of the other control chamber.
