An apparatus and method of mixing liquid fuel and air for an internal combustion engine includes an assembly providing a plurality of venturi passageways for accelerative drawing of ambient air therethrough by the vacuum created by the engine and an associated fuel supply conduit system and apertures in the venturis for aspiration of fuel into the air. One of the venturis communicates unobstructedly with the engine to provide a fuel-air mixture for idling operation and a valve arrangement effects opening and closing of at least some of the other venturis to communication with the engine responsive to increases and decreases in the vacuum. An enlarged chamber intermediate the venturis and the engine receives the fuel entrained airstream from such some venturis, reduces the velocity thereof, and thereby gravitationally separates therefrom the larger fuel droplets which will not quickly and completely combust in the engine. A recycling arrangement returns the separated droplets to the atomizing assembly. |
