Abstract
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.
