ABSTRACT:
A preheating system for internal combustion engine fuels. The parts of the system include a heat exchanger through which the fuel passes in heat exchange contact with exhaust gases from the engine, or, in some cases, the engine coolant. Where the heat exchange contact is with exhaust gas, the fuel is vaporized by heat from the gas prior to its introduction into the engine carburetor. Where the fuel passes in heat exchange relationship with engine coolant, it is heated to a point just below boiling before introduction into the carburetor. Where the fuel is heated by exhaust gas, the parts of the system include an accumulator between the heat exchanger and carburetor which serves the purpose of providing a reservoir of the vaporized fuel sufficient to satisfy any demand of the carburetor. The fuel heating system can be employed with a conventional gasoline carburetor where the heat source for the heat exchanger is the engine coolant. Where the heat source is exhaust gas, however, the engine will require the use of a modified butane carburetor in addition to its regular one, in which case the system includes a thermostatically controlled valve that operates to feed gas to the regular carburetor from engine start-up until the exhaust gas reaches a suitable temperature level, then the valve switches the gas flow from the regular carburetor into the heat exchanger. The incorporation of this system into an automobile results in a remarkable increase in engine efficiency and a decrease in exhaust pollutants.
