PURPOSE: To distribute fuel uniformly to each cylinder while reducing the number of used fuel injection valves.
CONSTITUTION: An orifice plate 4 provided with two right and left fuel amount regulating holes 3 having same diameters at a prescribed angle θ1 (0 to 25°), is provided on the top end of the valve body 1 of a fuel injection valve 10, and a cap 5 is mounted while sandwitching the orifice plate 4. In the cap 5, injection angle enlarging parts 5a, 5a which are formed in inclining holes having each prescribed angle θ2 (13° or more) are provided on right and left so as to enlarge a fuel injection angle, and an isolation part 5b is provided in a center so as to isolate those right and left injection angle enlarging parts 5a, 5a from each other. A notch is provided on a bulkhead for partitioning each intake pipe in intake pipe maurfold parts of two adjacent cylinders in an engine, and the fuel injection valve 10 is mounted in the notch.
