Abstract:
Among all combinations of two injection holes, in a combination in which when the injection holes are offset such that their central axes are coincident with each other in inlet openings, an inter-injection hole angle formed by the central axes is minimized, the inter-injection hole angle between the two injection holes is represented as γamin[deg], taper angles, which are formed by the respective contours of the injection hole inner walls in the cross sections along the virtual planes including the central axes of the two injection holes that allow the inter-injection hole angle to be minimized, are represented as θa 1  and θa 2[ deg], and when fuel is injected from the injection holes, average pressure of the fuel in the fuel passage is represented as P[Mpa], and the injection holes are formed so as to satisfy a relationship: γamin≥θa 1+θ a 2+0.5× P 0.6

Claim (Index 4):
The fuel injection device according to  claim 1 , wherein\n the nozzle part has a valve seat annularly formed around the inlet openings on the nozzle bottom portion, the fuel injection device further comprising: a cylindrical housing connected to the nozzle cylinder portion on a side opposite to the nozzle bottom portion; a needle that is provided within the housing so as to have one end contactable with the valve seat and to be able to reciprocate in the axial direction, and opens or closes the injection holes when the one end separates from or comes into contact with the valve seat; a movable core provided so as to be able to reciprocate together with the needle within the housing; a stationary core provided within the housing on an opposite side of the movable core from the valve seat; a coil capable of attracting the movable core toward the stationary core to move the needle to a side opposite to the valve seat when the coil is energized; and a valve seat side biasing component capable of biasing the needle and the movable core toward the valve seat.
