Abstract

Apparatus for a fuel injector nozzle (202) interfacing a fuel injector valve assembly (102) with a chamber inside an internal combustion engine housing (104). The nozzle (202) has one end (302) that is outboard relative to the chamber (110) in the housing (104) and an opposite end (404) that is inboard relative to the housing (104). The outboard end (302) is attached to the fuel injector valve assembly (102). The inboard end (404) has a surface that is substantially flush with the surface (110) of a lobe (204-L) defining the chamber (110). The nozzle (202) is hollow with a grouping of discharge ports (402) at the inboard end (404). The nozzle (202) receives fuel from the injector valve assembly (102) and ejects the fuel as spray from the ports (402) in a manner to optimize fuel combustion in the chamber (110).
