The pump delivers pressurized liquid alcohol to the primary heat exchanger where the alcohol fuel is heated above the vaporization point at ambient pressure. The heated fuel is next delivered to the carburetor where the vaporized alcohol is metered and mixed with air for proper combustion and then delivered to the intake system of a conventional internal combustion engine, or, alternately, by means of the fuel injection system, the fuel is delivered directly to the cylinders where it is mixed with air for proper combustion. A fuel pre-heater assembly utilizing waste heat from the engine may also be provided. | |
