ABSTRACT:
The invention relates to a fuel injection device for an air-compressing fuel-injected internal combustion engine, which has an injection line leading from a pump element of high pressure injection pump to a bifurcation branch leading to a main injection nozzle and a preinjection nozzle. A nozzle needle of the preinjection nozzle opens counter to the direction of flow of the fuel and has a body designed with a stepped piston which, in the case of a closure initiating fuel pressure lying above an opening fuel pressure of the nozzle needle, moves the nozzle into a position to end preinjection.
