ABSTRACT:
A vapor fuel system for an internal combustion engine includes two vaporizing units for vaporizing liquid fuel and mixing it with air and a vapor heat exchanger for heating the fuel vapor-air mixture prior to its combustion in the engine. Hot fluid circulating in engine's cooling system flows through a jacket integrally surrounding each of the two vaporizing units and the vapor heat exchanger to provide a source of heat for vaporizing the fuel and heating the fuel vapor-air mixture. A fuel line carrying the liquid fuel to each of the vaporizing units passes through the hot fluid-filled jacket surrounding each of the units, thereby preheating the fuel before it is vaporized. In an alternate embodiment of the invention, two solenoid valves, one along the fuel line leading to each vaporizing unit, act in conjunction with a timing means to alternate periodically activation and deactivation of the vaporizing units.
