Abstract

A fuel injector including a nozzle body having a bore defining a seating, a valve member having a plurality of passages providing fluid communication between the bore and a plurality of outlet openings, the outlet openings defining a first group of openings at a lower axial position on the valve member and a second group of openings at a higher axial position on the valve member. The valve member is slidable within the bore and is engageable with the seating to control fuel flow from the outlet openings. The outlet openings are shaped and orientated such that the sprays formed at the first and second groups of outlet openings do not interfere with one another.
