Tom Ogle ~ Vapor Fuel System
Fuel Economy System for an Internal Combustion Engine
Tom Ogle (December 11, 1979)
Abstract ~
A fuel economy system for an internal combustion engine which, when installed in a motor vehicle, obviates the need for a conventional carburetor, fuel pump and gasoline tank. The system operates by using the engine vacuum to draw fuel vapors from a vapor tank through a vapor conduit to a vapor equalizer which is positioned directly over the intake manifold of the engine. The vapor tank is constructed of heavy duty steel or the like to withstand the large vacuum pressure and includes an air inlet valve coupled for control to the accelerator pedal. The vapor equalizer ensures distribution of the correct mixture of air and vapor to the cylinders of the engine for combustion, and also includes its own air inlet valve coupled for control to the accelerator pedal. The system utilizes vapor-retarding filters in the vapor conduit, vapor tank and vapor equalizer to deliver the correct vapor/air mixture for proper operation. The vapor tank and fuel contained therein are heated by running the engine coolant through a conduit within the tank. Due to the extremely lean fuel mixtures used by the present invention, gas mileage in excess of one hundred miles per gallon may be achieved.

I have no idea what it all means, the only questions being; does it work? and where is it?

The fuel is vaporized with heat and the vapor makes its way to the engine due to the engine's vaccuum, as in a normal engine. The vapor's flow is controlled with a series of neoprene filters and valves coupled to the gas pedal. The part where it loses me is where it says that the engine operates cooler than a normal engine and the cooling system is actually used to heat the engine to aid in vaporization. I just dont understand how that would happen, a lean mixture makes more heat. The combustion of octane will release a certain amount of energy, the energy released it from the chemical bonds breaking down. Vaporization occurs within every engine.
A stoichiometric (chemically correct) mixture will provide a certain amount of energy, the only real variables determining power (change in pressure x change in volume = work done by engine/ cycle = nR x change in Temperature). The mass of air/fuel [nR ; where n= number of moles; a unit of measuring small amounts of elements and R= Universal gas constant] will be more or less constant throughout the engine's cycle.
If the engine can run cooler, less fuel would be required to make similar power; as the change in the mixture's temperature throughout the engine's cycle would be greater, therefore the work done by the engine per cycle would be greater (dWK=[nR]dT). In order to get 100 mpg out of a cleveland, you would need to essentially multiply the fuel economy by 10-15x what it would normally be. So dividing the amount of fuel by 10-15 would require a temperature change 10-15x greater than a typical 351c; or the air/fuel mixture would need to be well below freezing temperatures or the combustion temp would need to be temendous. However, it would require different tolerances within the motor (pistons, rings, etc.), different oils and alot of re-tweaking either way. It wouldn't be as easy as bolting on a carburetor.I'm calling BS on this one, 351 clevelands don't make more power running lean
. I would beleive it if a different fuel were used, as there are elements that are explosive in the presence of oxygen. I'm sure there are ways to make more power than with gasoline, who knows if its safe though.
