DETAILED DESCRIPTION OF THE INVENTION
[0051] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
[0052] When the combustion energy, in kJ per unit of molecular weight, of Olefins, represented by octene (C8), is compared to alkanes, represented by butane (C4), undergoes combustion that releases 789 kJ/unit of molecular weight that is dwarfed by the 400 kJ/unit of molecular weight of Octane (? Octene). Butane with a low boiling point, 20.66 degrees F. (6.3 degrees C.) is more appropriately to be blended with propane (C3) and used as liquified petroleum gas (LPG) fuel and not used to fuel for ICEs. However, butane gas is soluble in liquid gasoline and is a component found in all grades of the reformatted gasolines available in the US's 150,000 stations where gasoline is sold. The use of butane has the benefits of being: inexpensive; available in excess quantities at refineries; 1.98 times the energy density of octane; 102 ON vs. 100 ON for octane; a RVP of 52 making it the component of choice for use to add the requisite volatility for cold start of ICEs. However, butane's concentration in reformulated gasoline is limited to 2% by volume in summer blends and 10% in winter blends so as not to exceed a maximum standard for RVP of 9 psi and avoid the unwanted occurrence of vapor lock in the gasoline feed system to the ICE.
[0053] In the present invention, the possibility of excess butane producing vapor lock is eliminated by producing butane in a cylinder resident reaction only after the gasoline has passed through the feed system. The cylinder resident reaction that produces butane is represented by the hydrolysis of the olefin, represented by the octene (C8), in
[0054] The formulation shown in
[0055] The SMN contains lead and VMS fuel contains organopalladium or organoplatinum that each acts as a catalyst to reduce the energy threshold required for the hydrolysis of the olefins to occur and for the detonation of the EHN to occur. The allowable limit of lead in gasoline is 50 mg. In Test One and Test Two, the dosage of additive was 1.5 fluid ounces in 20 gallons of gasoline. In Test Three, the dosage of Additive used was 0.64 fluid ounces in 20 gallons of gasoline. In Test Four, VMS fuel blended organoplatinum, at a dose of 0.04 mg/gallon as platinum, the dosage of additive used was 0.64 fluid ounces in 20 gallons of gasoline.

The Improved Efficiency Triangle
[0057]
[0058] The double bonds between carbons in the olefins, present in gasoline, are heat and pressure sensitive. Reformulation of gasoline, performed in refineries, often involves high temperatures and pressures causing double bonds present in olefins (alkenes), to transform into single bonds present in alkanes. The extent of the reduction in olefins during gasoline reformation, is measured by the decrease in bromine number making this portion of the olefins unavailable for the hydrolysis reaction to occur. All gasolines, have a starting point, consisting of hydrocarbons derived from distillation of crude oil called straight run gasoline. The hydrocarbons in straight run gasoline distillation fraction has a boiling point range of 104 degrees F. (40 degrees C.) to 401 degrees F. (205 degrees C.). The commercially available gasoline that is 100% straight run contains a yellow dye signifying that it has not been taxed and is for off-road uses such as on farms. This gasoline contains eighty One percent (81%) by weight Olefins, that is the highest concentration in any commercially available gasoline. Therefore, yellow gasoline has the potential for producing the highest quantity of butane by the hydrolysis of the olefins. The second highest concentration of olefins in commercially available gasoline is in regular grade gasoline. The concentration of olefins in gasoline can be determined by dividing the bromine number by the number 2.4. the bromine number decreases as the grade of gasoline, and the price at the pump increase from regular, to mid-grade and the premium.
[0059] The cylinder pressure in the ICE is the sum of the engine's compression ratio, the contributions to RVP from the quantity of the butane in the gasoline and the quantity of butane produced by the cylinder resident hydrolysis reaction. The threshold pressure for the reaction to occur is ten (10) atmospheres. This pressure is achieved in an ICE with a compression ratio of 10. Engine's with higher compression ratios add additional pressure. The RVP of butane is 52 psi. Therefore, if the fuel had a 100% butane content, which it does not and cannot have, this would add 3.5 atmospheres: equal to a compression ratio of 13.5. For each 10% of the olefins hydrolyzed to butane there is an increase in the butane of almost 20% that, 2 moles of butane from each mole of olefins, results in an increase in the pressure of 0.7 atmospheres {(52/14.7)(20/100)} producing and apparent compression ratio increase of 0.7 to 10.7.
[0060] The starting octane number (ON) for the hydrolysis reaction to occur is the ON of 55 found for straight run gasoline: that is commercially available as yellow gasoline. Butane, with an ON of 102, increases the ON in proportion to the percent completion of the cylinder resident reaction that produces butane by the hydrolysis of olefins. If the hydrolysis reaction is sufficiently complete to produces 60% butane, then the ON of the gasoline in the cylinder is 94 (0.455+0.6102). The gasoline produced at this percent completion of the straight run gasoline is superior to a premium grade gasoline's ON of 91 and has an ON 3 units higher than the average premium grade gasoline that is commercially available in the US.

Test OneRacing Fuel
[0062]
Test TwoAdvancing of Spark Ignition
[0063]
[0064] The increase in the engine's efficiency with increased ignition advance is due to increased pressure in the compression stroke that results in the production of more net-work by the ICE. If ignition is too advanced, too much of the gas will burn while the piston is rising, resulting in a decrease in the ICE's ability to expend the work that must be done to compress the gas. These competing effects create a point at which optimum performance is achieved. The results in the occurrence of a point of maximization of engine's efficiency at an ignition advance that is specific to the racing fuel treated with 1.5 fluid ounces of additive in twenty (20) gallons of fuel.
Test ThreeLow Compression Engine
[0065] Fueling, a low compression engine, with regular gasoline, treated 0.64 fluid ounce of leaded additive, to 20 gallons of resulted in no discernable increase in miles per gallon. However, it was reported that there was an improvement in the engine's cold start. This test provides antidotal evidence that, even under low compression cylinder condition, a cylinder resident hydrolysis reaction occurs. This reaction resulted in the production of butane (C4) hydrocarbon that raises the Reed Vapor Pressure (RVP) so that the engine's cold start performance was improved. Because butane (C4) hydrocarbons have an enormously large RVP of 55, even a small increase in concentration of butane (C4) hydrocarbons in the cylinder's fuel can have a large effect on improving the engine's cold start performance.
Test FourComparison of Leaded and Un-Leaded Additive
[0066] Fueling, a high compression engine, with regular gasoline, treated 0.64 fluid ounce of leaded additive in one test and unleaded additive in another test resulted in increased mileage and power and increase in miles per gallon. Both the leaded and the unleaded formulation, shown in
[0067]
Observation
[0068] The production of gasoline in accordance with the present invention can be thought of as a combination of: 1) rolling back time to when the function of the refining was only distillation of crude to produce straight run gasoline rich in the olefin component; and 2) harnessing today's high compression engine's cylinder to upgrade low octane straight run gasoline to high octane premium grade by converting a portion of the olefins present to petroleum gas.
[0069] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
