Abstract

A fuel injector nozzle for dispersing fuel during a normal combustion operation and a supplemental combustion operation, the fuel injector nozzle comprising: a plurality of first outlet openings (24) configured to disperse fuel during homogeneous charge compression ignition and non-homogeneous charge compression ignition; and a plurality of second outlet openings (48) configured to disperse fuel only during non-homogeneous charge compression ignition, wherein fuel dispersed from the plurality of second outlet openings collides with and subsumes fuel dispersed from the plurality of first outlet openings.
