Abstract:
1. A four quarter butterfly valve system for controlling the passage of air through a cylindrical air passageway to achieve a vortex flow to increase the efficiency of an internal combustion engine comprising, in combination: an internal combustion engine with an upper extent formed with a circular opening there through for the passage of ambient air to be combusted in the internal combustion engine, the circular opening having a vertical axis; an air cylinder having an upper end in communication with ambient air to be received and then passed to the internal combustion engine, the air cylinder having a lower end formed with a flange coupled to the upper extent of the internal combustion engine, the air cylinder also having an internal cylindrical passageway aligned with the circular opening of the internal combustion engine, the cylindrical passageway having a vertical axis coaxial with the vertical axis of the circular opening; an air control assembly including a pair of similarly configured semicircular plates positioned within the cylindrical passageway of the air cylinder, the control assembly also including a pair of axially aligned bearing apertures with a horizontal axis formed in the air cylinder at a central elevation thereof with a first shaft and a second shaft each rotatably received in an aperture for independent oscillation, the first shaft having an interior end in the cylindrical passageway of the air cylinder with a mating projection and the second shaft having an interior end in the cylindrical passageway of the air cylinder with a mating recess, the first and second shafts having flat axial sections receiving and supporting the plates and for allowing oscillation of the first and second shafts and plates with respect to each other about the horizontal axis coextensive with the axis of the bearing apertures and perpendicular to the vertical axis of the cylindrical passageway of the air cylinder, the first and second shafts also having exterior ends located outside of the air cylinder on opposite sides thereof; a pair of fuel introduction openings with each fuel introduction openings containing a line for the introduction of fuel into the air cylinder at an elevation between the axis of rotation of the plates and the flange of the air cylinder; and a rocker arm secured to the exterior end of each shaft with a driver secured to each rocker arm to oscillate the rocker arms and shafts and plates independently of each other whereby the flow of air may be selectively controlled to generate a vortex flow by a user manipulating the drivers to open and close four quarter quadrants of the cross section of the cylindrical passageway of the air cylinder.
