Abstract:
An improved spray bar pair for mixing fuel and oxidizer for introduction into the intake manifold of an internal combustion engine comprising:a fuel bar wherein said fuel bar is formed from a conduit having an outside and an inside;a gas bar wherein said gas bar is formed from a conduit having an outside and an inside;wherein said gas bar has an axial gas near position line and two gas aperture lines each of said lines falling on said outside of said gas bar;wherein said fuel bar has an axial fuel near position line and two fuel aperture lines each of said lines falling on said outside of said fuel bar;said gas bar and said fuel bar being positioned one over the other, thereby forming a spray bar pair, such that said gas near position line and said fuel near position line are parallel to each other that said near position lines are separated by a distance ranging from 0.001-inches to 0.20-inches as measured linearly from said gas near position line to said fuel near position line;means for mounting said spray bar pair near the intake manifold while maintaining said separation distance;wherein each of said gas aperture lines are positioned axially along said outside of said gas bar at a gas angle falling within the range 30 degrees to 70 degrees as measured circumferentially from said gas near position line to each of said gas aperture lines;wherein each of said fuel aperture lines are positioned axially along said outside of said fuel bar at a fuel angle falling within the range 20 degrees to 60 degrees as measured circumferentially from said fuel near position line to each of said fuel aperture lines;a plurality of gas spray apertures each thereof lying along one or the other of said gas aperture lines and forming a conduit between said inside and said outside of said gas bar; and,a plurality of fuel spray apertures each thereof lying along one or the other of said fuel aperture lines and forming a conduit between said inside and said outside of said fuel bar.
