Abstract
The invention relates to a fuel injection device (100) for a compression-ignition engine, comprising a first storage unit (20) which can be supplied with fuel by at least one high-pressure pump (16), the first storage unit (20) being arranged preferably inside the high-pressure pump (16), a first connecting line (26) from the first storage unit (20) to a second storage unit (30), and a second connecting line (40) from the second storage unit (30) to a fuel injector (50).
Claims20
A fuel injection device (100) for a compression-ignition engine, the fuel injection device comprising a first storage unit (20) configured to be supplied with fuel by at least one high-pressure pump (16), a first connecting line (26) from the first storage unit (20) to a second storage unit (30), and a second connecting line (40) from the second storage unit (30) to a fuel injector (50), wherein a third storage unit (42) is arranged inside a housing (52) of the fuel injector (50), in which third unit an injection element (46) is arranged in a manner so as to be moved by lifting, and wherein the storage volume of the third storage unit (42) is a volume, corresponding to a plurality of nominal injection amounts of the fuel injector (50).
