Alcohol fuel conversion apparatus
First Claim
1. Alcohol fuel conversion apparatus for internal combustion engines comprising:
- fuel storage means for containing an alcohol fuel;
primary heat exchange means in fluid communication with said fuel storage means for transferring heat to pressurized alcohol contained within said heat exchange means;
a heat source for heating said primary heat exchange means;
pressure relief valve means in closed fluid communication with said primary heat exchange means for releasing heated pressurized alcohol into an expansion chamber;
converter means including said expansion chamber in fluid communication with said pressure relief valve means for receiving the heated pressurized alcohol and for the vaporization of the alcohol;
fuel injection means in fluid communication with said converter means for injecting vaporized alcohol into the cylinders of an internal combustion engine for mixing with air within the cylinders for proper combustion; and
pump means for pressurized pumping of alcohol from said 23 fuel storage means to said primary heat exchanger means, converter means, fuel injector means, and to the engine.

Abstract
Alcohol fuel conversion apparatus for internal combustion engines including a fuel tank, a fuel pump, a primary heat exchanger, a heat source, a converter and a carburetor or fuel injection system. 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.
