Abstract
A spray bar pair for use in the performance car industry is disclosed. The spray bar pair may be installed in a spray bar plate for mounting in the air flow from the throttle valve and injects a well mixed mixture of fuel and gas into the intake manifold of an engine. The spray bar pair utilizes carefully a chosen pattern of spray apertures set at such angles in the spray bar pair to ensure proper mixing. Several methods of use for the improved spray bar pair are given.
Claims16
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.

An improved dual spray bar assembly 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 metal conduit having an outside, an inside, and two ends;
- a gas bar wherein said gas bar is formed from a metal conduit having an outside, an inside, and two ends;
- 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 0.010-inches to 0.20-inches as measured linearly from said gas near position line to said fuel near position line;
- a spray bar plate having one or more gas ports, one or more fuel ports, and a plurality of terminating apertures into each of which an associated gas bar or fuel bar may be inserted and in which one end of each fuel bar terminates within a fuel connector within said fuel port whereas said other end thereof terminates in an associated terminating aperture within said spray bar plate and in which one end of each gas bar terminates within a gas connector within said gas port whereas said other end thereof terminates in an associated terminating aperture within said spray bar plate 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 wherein each of said gas apertures has a diameter within the range 0.015-inches to 0.030-inches and are separated by a separation distance within the range 0.010-inches to 0.500-inches;
- 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 wherein each of said fuel apertures has a diameter within the range 0.02-inches to 0.03-inches and separated by a separation distance within the range 0.20-inches to 0.30-inches.
