Abstract
A fuel injector which is enabled to form a fuel spray efficiently and properly into a flat sector shape by improving the angle, dispersion and atomization of the spray and by optimizing the spray tip penetration. A slit-shaped nozzle outlet 4 is constructed such that its transverse walls from its inner end 9 to its outer end 10 have an included angle .gamma. of 20 to 180 degrees, such that an angle .beta. of 0 to 90 degrees is made between the axis of the fuel injector and the opening direction of the slit-shaped nozzle outlet 4, such that the nozzle outlet 4 is diverged outward from a plane joining the axis to the fuel injector and the inner end 9, and such that the opposite portions of the inner end 9 have a width W of 0.05 mm to 0.24 mm. By combining these constructions suitably, the fuel spray can be formed efficiently and properly into a flat sector shape thereby to improve the fuel injection characteristics.
