Method and apparatus for supplying fuel to an internal combustion engine

Abstract From the Canadian patent

A fuel supply system for an internal combustion engine wherein liquid fuel, as from an automobile gas tank is supplied to a vapor, chamber to maintain a predetermined liquid fuel level in the base of said chamber and in such chamber is transformed into vapor and eventually fed to the engine's intake manifold. Ambient air is admitted to the vapor chamber by an adjustable inlet valve and as the air is drawn through the chamber on its way to the engine it entrains the fuel vapors in the desired fuel-air mixture. The vaporizing or the liquid is increased by an absorbent splash assembly so supported in the vapor chamber that at least a part of such assembly normally engages the liquid fuel.
