Benefits of technology

[0002]Alternative fuels, as defined by the Energy Policy Act of 1992 (EPA Act), include ethanol, natural gas, propane, hydrogen, biodiesel, electricity, methanol, and p-series fuels. These fuels are being used worldwide in a variety of vehicle applications as a replacement, either in whole or in part, to petroleum based fuels (i.e. gasoline and diesel). Environmental advantages to using alternative fuels in vehicles include the reduction in harmful pollutants and exhaust emissions. In addition, most of these fuels can be domestically produced, thereby reducing the U.S.'s demand on foreign oil, as well as derived from renewable sources, as opposed to petroleum fuels.

Problems solved by technology

One major problem with these ethanol / petroleum fuel blends is that they contain low BTU's, and therefore a reduction in fuel economy.

example 1

[0023]The follow fuel composition (i.e. Fuel Composition A) was tested against a standard fuel in a 4-cycle Briggs & Stratton engine: 90% v / v petroleum gasoline (91 octane, unleaded), 5.7% v / v ethanol, and 4.3% soybean / d-limonene composition (the soybean / d-limonene comprised 90% methyl ester of soybean oil and 10% d-limonene). The standard fuel was 91 octane unleaded gasoline.

[0024]One liter of the standard fuel was added to the 4-cycle engine, and the engine was allowed to run for one hour (RPM=Idle). The following results were recorded:

[0025]Head temperature: 166° F.

[0026]Response time rating: 6-7 (subjective, based on a scale of 1-10, with 10 being best)

[0027]Exhaust temperature: 365° F.

[0028]After the foregoing results were recorded for the standard, one liter of Fuel Composition A was added to the same 4-cycle engine, and the engine was again allowed to run for one hour. The following results were recorded:

[0029]Head temperature: 154° F.

[0030]Response time: 9-10 rating (subject...
