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, at least two metering orifices, and at least one flow channel. The at least two metering orifices are generally located along an axis extending radially away from the longitudinal axis and radially outward of the seat orifice. Each of the metering orifices has a center defined by the interior surface of the metering orifice extending through the disc. The at least one flow channel extends radially away from the longitudinal axis towards each of the at least two metering orifices. And a method of atomizing fuel is also described.
