IC engine fuel supply system

An IC engine fuel supply system having a vaporizing/pollution reducing carburetor for an IC engine, the vaporizing/pollution reducing carburetor comprising:

• a vaporization chamber having a mantle means for suspending fuel within the vaporization chamber, and a perforated annular washer located above the mantle means so that the fuel must flow through the perforated annular washer when leaving the mantle means;
• a fuel intake means located in operative association with the vaporization chamber for metering an amount of the fuel from a fuel supply to the mantle means for suspension in the vaporization chamber;
• an air intake means located upstream of the vaporization chamber, the air intake means having a valve means for regulating the amount of air flowing through the vaporization chamber in accordance with the pressure in an intake manifold of the IC engine, the air intake means being disposed so that air is directed through the mantle means for vaporizing said fuel suspended in the said mantle means;
• a fuel scavenger means in operative association with the mantle means for removing excess and non-vaporized fuel from the mantle means and from the vaporization means and returning said fuel to the fuel supply;
• and,
• a conduit means for introducing vapors from the vaporization chamber into an intake manifold of the IC engine.
