Disclosed is a fuel injection nozzle assembly comprising a poppet type valve assembly capable of producing a circumferential spray pattern. The fuel injection nozzle assembly includes a nozzle body defining a valve outlet into which is fitted a needle valve having a flanged portion extending from the nozzle body. The flanged portion opens and closes the valve outlet as the needle valve travels up and down the nozzle body as dictated by the fuel pressure within the nozzle body. The flanged portion may further direct the fuel spray into a combustion chamber.
