Abstract:
1. A CNG fuel injector for a fuel system of an internal combustion engine, the fuel system having a fuel rail and an engine manifold, the fuel injector comprising: a fuel inlet for fluid communication with the fuel rail; a fuel outlet having an orifice disposed along a longitudinal axis for fluid communication with the engine manifold; and a member proximate the fuel outlet downstream of the orifice for dispersing the CNG in a direction skewed from the longitudinal axis as the CNG flows from the orifice into the engine manifold, the member comprising a surface that defines a volume, the volume suppresses the flow of the CNG as the CNG flows from the orifice, the surface disperses the CNG in multiple directions skewed from the longitudinal axis as the CNG flows into the engine manifold, wherein the entire surface is porous and the CNG flows substantially through the entire surface.
