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: a generally planar surface, a plurality of metering orifices that extends through the generally planar surface, the metering orifices being located radially outward of the seat orifice; and at least one flow channel having a cross-sectional area that decreases in magnitude starting at a location spaced from the longitudinal axis to proximate a perimeter of a metering orifice. A seat subassembly and a metering orifice disc are described. And a method of atomizing fuel is also described.
