Fluid injector orifice plate for colliding fluid jets

An injector nozzle used with an internal combustion engine for guiding and shaping a fluid flow, comprising:

• a nozzle body comprising an inlet for admitting the fluid flow and an outlet;
• an orifice plate provided at the outlet of the nozzle body, wherein the nozzle body and the orifice plate are both configured to extend symmetrically with respect to a central axis, wherein the orifice plate has an interior surface facing the nozzle body and an opposite exterior surface, the interior surface and the exterior surface being substantially planar and parallel to each other to define a thickness of the orifice plate;
• and
• a cavity defined between the orifice plate and the nozzle body, wherein the fluid flow converges at the cavity,
• wherein the orifice plate comprises a plurality of fluid passageways, each fluid passageway having an orifice on the exterior surface, said fluid passageways extending from the interior surface to the exterior surface and being in fluid communication with the cavity, wherein the fluid flow diverges through the fluid passageways to create a plurality of stream jets, and
• wherein at least one focal point and at least one included angle associated with the focal point are created where the imaginary extensions of the plurality of fluid passageways converge, and wherein the fluid passageways are angled such that they extend toward the central axis in the direction from the interior surface to the orifice on the exterior surface of the orifice plate;
• wherein the plurality of fluid passageways forms a first focal point and a second focal point, and at least one of the first focal point and the second focal point is offset with respect to the central axis and
• at least two stream jets from the plurality of stream jets converge at the first focal point to atomize the fluid and at least two stream jets from the plurality of stream jets converge at the second focal point to atomize the fluid.
