摘要： A fuel injector is provided. The fuel injector also includes a multi-layer orifice plate assembly located at the housing outlet. The orifice plate assembly includes a first orifice plate having a plurality of first openings extending therethrough and a second orifice plate disposed proximate to the first orifice plate. The second orifice plate includes a first face having a perimeter, and a plurality of channels extending radially therethrough to the longitudinal axis. The second orifice plate also includes a second face disposed opposite the first face and a plurality of second openings extending between the first face and the second face. The fuel injector also includes an air assist sleeve disposed about the housing proximate to the outlet. The air assist sleeve includes at least one air channel in communication with the plurality of channels. A method of providing a fuel/air mixture is also provided.

摘要： The atomizer is a cap-shaped shroud that contains a flat stamped metal insert. When assembled onto the nozzle of a fuel injector, the atomizer causes the insert to be axially sandwiched between the shroud's end wall and the exterior end of the nozzle. In the zone of sandwiching, the insert has six channels of circumferential discontinuities that in cooperation with the nozzle end and the shroud's end wall define air assist openings for the assist air to flow radially inwardly toward the injected fuel that has just been injected from the nozzle. The six channels are divided into one set of two each angularly spaced channels that are directed to one of the two axis of fuel flow; another set of two each angularly spaced channels that are directed to the other of the two axis of fuel flow; and two diametrically opposed channels lie along a diameter of the disk that is normal to and bisects a diameter that passes through the two axis of the fuel flow.

摘要： The atomizer is a cap-shaped shroud that contains a stack of flat stamped metal inserts. When assembled onto the nozzle of a fuel injector, the atomizer causes the inserts to be axially sandwiched between the shroud's end wall and the exterior end of the nozzle. In the zone of sandwiching, the inserts have circumferential discontinuities that in cooperation with the nozzle end and the shroud's end wall define air assist openings for the assist air to flow radially inwardly toward the injected fuel that has just been injected from the nozzle. An air assist opening in one insert is thereby both circumferentially and axially offset from an air assist opening in another insert.
