Fuel economizer employing improved turbulent mixing of fuel and air

A carburetor for mounting on an internal combustion engine comprising:

• a housing,
• a hollow mixing chamber provided within said housing and having an air inlet at one end and a fuel outlet at the other end of said housing,
• a fuel reservoir mounted adjacent said housing,
• a sleeve having a funnel shaped configuration for mounting in the interior of said chamber forming a venturi shaped opening positioned longitudinally of said housing tapering from a given diameter at said one end to a smaller diameter opening at said other end of said chamber,
• a fuel injection means interconnecting said reservoir with the interior of said venturi at a point adjacent its smaller diameter and substantially axially aligned with the longitudinal axis of the venturi whereby the lower pressure of air flowing through said venturi causes fuel to flow out of said fuel injection means into said venturi,
• the smaller diameter of said venturi being of a predetermined size large enough to cause a predetermined lower pressure therein sufficient to draw fuel out of said fuel injection means, and
• a hollow extension connected to said other end of said housing for receiving at one end the fuel and air mixture from said venturi and discharging it from its other end,
• said extension being provided with at least two spacedly arranged air inlet port means extending into the hollow interior of said extension substantially at right angles to the longitudinal axis of said extension for injection at all engine speeds through its fully opened ports atmospheric air into the fuel air mixture from said venturi passing therethrough,
• the injected air passing through said air inlet port means turbulently actuating said fuel air mixture and additionally adding the remaining necessary air needed for complete fuel combustion in the associated internal combustion engine.
