ABSTRACT:
An evaporative carburetor has a normally pressure-tight chamber which houses an evaporator tray to which a fuel supply delivers gasoline. A first air passage in the carburetor chamber communicates from a first, automatically-valved, air inlet to pick up gasoline particles and vapor from the evaporator tray. A second air passage communicates from the evaporator tray to a mixing region and includes a particle arrester. A heater maintains the evaporator tray and the second passage above a selected temperature. A second, externally-controlled, valved inlet feeds air to the mixing region, and a third air passage communicates from the mixing region to a throttled output port. An aqueous control liquid is injected into the air stream in the third passage.
