FUEL INJECTION VALVE

A fuel injection valve is provided which includes a valve seat member (3) having a valve seat (8) and a nozzle (10) that is provided so as to be connected to a front end part of the valve seat member (3) so as to be positioned on the downstream side of the valve seat (8) and has a plurality of fuel discharge holes (11b) arranged around an axis (A) of the valve seat member (3), wherein the angle formed between the center line (Lb) of each of the fuel discharge holes (11b) and an inner end face (10a) of the nozzle (10) is set at an obtuse angle (±) on the side closer to the outer periphery of the nozzle (10) with respect to the center line (Lb) and an acute angle (²) on the side closer to the center of the nozzle (10) with respect to the center line (Lb), and fuel injected from a fuel discharge hole (10b) produces a fuel spray form (fb) as a fuel film having an arc-shaped cross section with a convex face facing the nozzle outer periphery side. This enables the loss of fuel injection energy to be reduced and the outline of a fuel spray form produced by injected fuel to be clear, thus improving penetration properties.
