ABSTRACT:
A director plate system for a fuel injector for use in an internal combustion engine. The system includes flow channels for directing the fuel stream radially inward toward the discharge holes. The cross-sectional area of the flow channels diminish inwardly, in the direction of flow, to accelerate the fuel stream. A swirl element, for imparting tangential velocities or eddies to a plurality of individual fuel streams, can be combined with the radially inward directed flow channels. The director plate system may be provided as individual plates in a stack or may be combined with each other and/or the valve seat in a variety of plate configurations to simplify the number of components.
