ABSTRACT:
A fuel injection nozzle for spraying a swirl of fuel, includes a nozzle body having a bore, an orifice communicated with the bore, and a wall defining the bore and the orifice. The bore for receiving an axially movable valve body has a first center axis and the orifice has a second center axis. An inlet open to the bore and an outlet open to outside the nozzle body. The wall includes a first circumferential edge portion defining the inlet of the orifice and a second circumferential edge portion defining the outlet of the orifice. A sprayed fuel body formed by fuel discharged from said orifice, has a third center axis. The first circumferential edge portion is so arranged as to allow the first center axis to be positioned inside the inlet. The second circumferential edge portion is so contoured as to allow at least a portion of the second circumferential edge portion to be out of a plane normal to the second center axis.
