A compressed natural gas fuel injector having a housing, an inlet, an outlet, a seat, a closure member, and an internally mounted nozzle. In a preferred embodiment, the inlet and outlet communicate a flow of gaseous fuel regulated by the closure member. The gaseous fuel passes through the seat, which is secured to a rim surface of a retainer portion of the internally mounted nozzle, and into a flow passage that further communicates the flow of gaseous fuel into one or more flow channels. The orientation of the flow channels within the internally mounted nozzle greatly affects the discharge pattern and mixing characteristics of the gaseous fuel within an intake manifold. A method of flowing gaseous fuel through the fuel injector is also described. |
