ABSTRACT:
A fuel injector is described. The fuel injector includes an inlet, outlet, seat, closure member, and a metering orifice disc. The metering orifice disc is disposed between the seat and the outlet. The metering orifice disc includes an outer wall having a surface that defines first and second outer chords generally about the longitudinal axis A-A. The first outer chord intersects the second chord and has a length different than the length of the second outer chord. The metering orifice disc includes an inner wall having a surface that defines first and second inner chords. The first and second inner chords extend generally transverse to the longitudinal axis A-A. The first inner chord intersects the second inner chord. The first inner chord has a length different than the length of the second inner chord. Methods of atomization and targeting are also described.
