Abstract
A fuel injection valve includes a valve seat member having a valve seat and a valve bore provided through a central portion of the valve seat, and an injector plate coupled to an outer end face of the valve seat member and having a plurality of fuel injection bores arranged in an annular shape surrounding an axis of the valve bore. A fuel diffusion chamber is defined between the valve seat member and the injector plate, and faced by the valve bore and all the fuel injection bores. The plurality of the fuel injection bores are formed in parallel to the axis of the valve bore, and the spreading angle of a fuel spray foam formed by the fuel injected from the fuel injection bores is determined depending on an axis distance between the valve bore and each of the fuel injection bores. Thus, it is possible to determine the spreading angle of the fuel spray foam as desired.
