ABSTRACT:
A carburetion device comprises a vacuum-tight vaporization chamber into which fuel and air are drawn by the vacuum produced by the engine. The vaporization chamber is supplied fuel and air through fuel and air conduits. The air supply conduit terminates at its outlet end in the vaporization chamber adjacent a barrier which contains one or more diffusion orifice. The engine vacuum draws the fuel and the air from the conduits, through the diffusion orifice, and into a vapor supply conduit which conducts the vaporized fuel/air mixture to the engine cylinders. The inlet end of the air supply conduit is provided with a flow-resistant valve so that a partial vacuum is maintained in the vaporization chamber. The flow resistant valve may be adjustable to enable adjustment of the richness and leanness of the engine. A means may be provided for adjusting the distance between the outlet end of the air supply conduit and the barrier containing the diffusion orifice. There also may be provided a choke assembly for regulating the richness of the vaporized fuel/air mixture and a throttle assembly.
