A fuel injection nozzle assembly (10) for injecting fuel into the combustion chamber of an internal combustion engine. A needle (26) of the nozzle assembly is forced upwardly against the downwardly directed force of a spring (28) by the high pressure of fuel which is fed through a fuel passageway (20). The fuel is forced through nozzle discharge orifices (50) which are in fluid communication with the combustion chamber. Each of the nozzle discharge orifices (50) includes a flow control orifice portion (52) having a circular cross-section which regulates the amount of fuel which passes through the orifices (50) and a connecting dispersing portion (54) which progressively increases in area to break up and disperse the fuel into a cloud-like mist that conforms to the configuration of the combustion chamber so that there be minimized contact with the walls thereof for optimized fuel burns.
