Abstract
Abstract A internal combustion engine fuel vaporizing device, including a vaporator tank assembly and air mixture assembly, connect by a tube. The vaporizing device consists of a fuel intake and float mechanism, a number of air intakes, some of which may include the catalytic device attachment and supplemental heater coils and a non-volatile particle reservoir. The air mixture consists of an air intake, two anti-backfire devices, a baffle system and a throttle mechanism.

An internal combustion engine vaporator system comprising: a vaporator tank which provides an enclosed chamber for containing a liquid fuel, means for supplying liquid fuel to said chamber; float means for maintaining a specified level of liquid fuel in said vaporator tank; an air inlet tube extending below the level of the liquid fuel; a porous zinc catalyst device positioned completely below the level of the liquid fuel and attached to said tube; said catalytic device being provided to separate the light gasoline ends from the heavy hydrocarbons, the lighter ends vaporizing quickly into the air bubbling up through the fuel from the air inlet tube, and the non-volatile parts collecting in a particle reservoir means on the bottom of the vaporator tank, said reservoir being removable for cleaning, a heating coil wrapped around the tube, said heating coils being heated by engine coolant tapped from the engine cooling system, said heating coils enhancing the evaporation process; an auxilliary air inlet provided in said vaporator tank and including a valve therein for controlling additional air as needed; an air-fuel mixing chamber means; air-fuel conduit means for connecting said vaporator tank to said air-fuel mixing chamber means; a backfire valve device; said air-fuel conduit means including said backfire valve device to prevent liquid fuel from being expelled from the vaporator tank in the event of a backfire; an additional air inlet/outlet device provided for the air-fuel mixing chamber means in order to add more air and allow release of backfire pressure, a system of baffle plates positioned in the air-fuel mixing chamber to further mix the air and gas vapor; and a conduit connected to and extending between the air/fuel mixing chamber and the intake manifold of the engine to allow the fuel/air mixture to flow to the combustion chambers.
