ABSTRACT:
A fuel collision surface 40 is provided so as to be spaced from and axially opposite to a fuel injection port 14. A ratio of a width of the fuel collision surface 40 to a diameter of the fuel injection port 14 is set in the range of 0.2-0.3 so that fuel flows in a membrane-like pattern in branch ports 34 without attaching to the branch port surfaces and is effectively atomized. Further, it is desirable that an angle defined between an air injection passage 36 and a fuel injection valve axis is set in the range of 45.degree.-75.degree. so that a good air atomization due to air injection is obtained.
