Abstract
Past fuel injection nozzles have attempted to provide a structure to reduce exhaust emissions, generally NOx. Such nozzles have failed to attain adequate reduction of exhaust emissions. The present fuel injector structure has resulted in reduced NOx emissions. The structure includes a housing having a central axis and a bore coaxial therewith. An enlarged diameter portion of the housing has a plurality of swirler vanes positioned therein. A frustoconical blending portion is connected between the enlarged diameter portion and the bore. The structure further includes an angled passages intersecting with the bore and being tangent thereto. The unique structure swirls the air and fuel as they meet and mix within the bore. The angular velocity of the air and fuel are additive and provide the fuel injector nozzle with a structure that results in reduced NOx emissions.
