ABSTRACT:
A device for forming a charge of fuel and air and for delivering the charge to an engine for combustion, the invention and the several embodiments thereof primarily comprise a chamber within which air and fuel are caused to mix. Fuel is introduced into the chamber and into contact with air which is caused to flow through the chamber. A portion of the fuel is vaporized within the chamber and is directed along with commingled air to the engine for combustion. That portion of the fuel which is not vaporized is returned to the fuel tank. Air is drawn into the chamber preferably by the influence of a vacuum created by the engine, the air preferably entering the chamber from more than one inlet and mixing with fuel introduced near the top of the chamber and onto a shroud over which at least a portion of the fuel spreads into a relatively thin layer as the fuel flows toward the lower portion of the chamber to mix with the air. Air is preferably drawn into the chamber internally of the shroud and at locations near the lower portion of the chamber and proximate to lower edge portions of the shroud.
