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.
I agree you have a lot of equations and physics data which of course I don't understand. I believe I read the statement somewhat differently than you have stated though regarding the engine, water, and gasoline temperatures and heating. I think the statement was that he engine and cooant temps were lower and to increase the vaporisation of the fuel, a reinforced gasoline tank was designed and the tank was heated.
(quote) "The Chapin US Pat. No. 1,530,882 discloses a gasoline tank surrounded by a water jacket, the latter of which is included in a circulation system with the radiator of the automobile. The heated water in the circulation system causes the fuel in the gasoline tank to readily vaporize. Suction from the inlet manifold causes air to be drawn into the tank to bubble air through the gasoline to help form the desired vapor which is then drawn to the manifold for combustion. " etc.
Many years ago, before auto seat belts became widespread, a man was on the old, old Joe Pyne TV show and demonstrated a "Kinetic Energy" Car seat, that a driver's seat upon headon collision up to 35 miles per hour would shear bolts, rotate and the driver would tae the impact on his buttocks. Demonstraions showed it worked as in an impact the first motion of the body was backwards, although it worked was not practical because of other, ie side or up and down motions, therefore was never produced.
I wonder how the learned Professors certifying the test of Ogle's car would explain the test in today's world?
I am inquisitve not condradictory. I use many things because they work, not because I know HOW they work.
Thanks for your participation.
