ABSTRACT:
An induction system for a gasoline-fueled four-cycle engine having a carburetor which delivers an air/fuel mixture through a primary venturi to a "hot box" evaporation container located in the engine exhaust stream causing any liquid gasoline to be vaporized. The vaporized air/fuel mixture is then conducted to the intake manifold. In V-type engines the "hot box" is located in the exhaust cross-over. At high load a secondary venturi delivers air/fuel mixture directly to the intake manifold. Fuel distribution in multicylinder engines is thereby improved permitting leaner operation without misfire, resulting in decreased hydrocarbon and carbon monoxide emission.
