ABSTRACT:
A fuel injector is shown and 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 plurality of metering orifices disposed about the longitudinal axis and a flow channel to each metering orifice disc so that, when the inlet of the fuel injector is provided with a pressurized fluid over a range of pressure from 200 kiloPascals to 600 kiloPascals and the closure member is actuated to the first position, the metering orifice disc provides an atomized fluid having a Sauter-Mean-Diameter of less than 70 microns proximate the outlet of the fuel injector. A method of atomizing is also provided.
