Summary: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 theta1 (0 to 25 deg.), 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 theta2 (13 deg. 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.
