<p>For an automobile with a gasoline fuel system wherein fuel is delivered by a fuel pump from the gas tank to a carburetor and on to the engine through an intake manifold, a substitute non-petroleum fuel system including a storage tank from which liquid fuel is pumped to an atmospherically maintained vaporization tank fitted with a heating coil. Mixed air and fuel vapors, the flow being regulated through a second accelerator, are fed directly from the vaporization tank to the intake manifold of the engine. The vapor tank is also equipped with an electrical resistance heater to facilitate engine starts. An alternative embodiment teaches mechanical linkage and circuitry for selectively operating either the gas or substitute fuel system through a single accelerator pedal.</p> |
