A fuel injection device for internal combustion engines, especially two-stroke diesel engines, comprising an eccentric injection-nozzle tip (4) protruding into an associated combustion chamber, whereby said nozzle tip has a pocket drill hole (3) with several outgoing injection-nozzle drill holes (13) which can be impinged upon with fuel. At least the axes of the outer nozzle tip drill holes (13) of said row of drill holes are directed inwards in relation to a radial progression. The conditions for fuel admission are approximately the same for all nozzle drill holes (13) resulting in a stable jet. Admission chambers (16) depart from the pocket drill hole (3) and are assigned to at least one part of the nozzle drill holes (13), whereby the diameter inside the chambers is greater than the diameter of the nozzle drill holes (13) and said chambers are designed in such a way that at least similar length ratios exist for all nozzle drill holes (13) in the row of drill holes. |
