Abstract
Present fuel injectors fail to be cost effective and with the complexity of recent fuel injectors tend to be labor intensive. The present fuel injector and method of making the fuel injector provides a cost effective fuel injector which reduces the labor intensiveness of manufacturing. The manufacturing of the fuel injector includes the separate formation of a first unitary component, a second unitary component and a third unitary component by individual castings. The unitary components are positioned relative one to another and welded forming the fuel injector having a preestablished configuration. The unitary components are individually cast and each include an as cast complex configuration verses a plurality of individual components being welded in subassemblies and into a final assembly.
