Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
A fuel comprising: an ethanol base having a composition by volume percent of about 70% to about 85% ethanol and about 30% to about 15% water; a volatile hydrocarbon component in an amount of about 4% to about 10% by volume of the ethanol base, said hydrocarbon component being selected from the group consisting of lower alkanes, alkenes, alkynes, dienes, or cyclo-forms thereof, having from 1 to 6 carbon atoms; and benzene in an amount sufficient to prevent separation of the water from the other components of the fuel.
Claim 2
Dependent Claim
89 words
A fuel comprising: an ethanol base having a composition by volume percent of about 70% to about 85% ethanol and about 30% to about 15% water; a volatile hydrocarbon component in an amount of about 4% to about 10% by volume of the ethanol base, said hydrocarbon component being selected from the group consisting of lower alkanes, alkenes, alkynes, dienes, or cyclo-forms thereof, having from 1 to 6 carbon atoms; and benzene in an amount sufficient to prevent separation of the water from the other components of the fuel.
Claim 3
Dependent Claim
39 words
The fuel of claim 1 further comprising a lubricating oil component in an amount of about 1% to about 10% by volume of the ethanol base, said lubricating oil component being capable of protecting engine parts from excessive wear.
Claim 4
Dependent Claim
28 words
The fuel of claim 1 wherein the ethanol base has a composition by volume of about 75% to about 80% ethanol and about 25% to about 20% water.
Claim 5
Dependent Claim
12 words
The fuel of claim 1 wherein said volatile hydrocarbon component is acetylene.
Claim 6
Dependent Claim
17 words
The fuel of claim 1 wherein benzene is in an amount of about 3% to about 10%.
Claim 7
Dependent Claim
20 words
The fuel of claim 2 wherein said lubricating oil component is produced from sunflower seed, castor bean, safflower, or soybean.
Claim 8
Dependent Claim
20 words
The fuel of claim 6 wherein said lubricating oil component is in a concentration of about 3% to about 5%.
Claim 9
Dependent Claim
92 words
A fuel comprising: an ethanol base having a composition by volume percent of about 70% to about 85% ethanol and about 30% to about 15% water; acetylene in an amount of about 4% to about 10% by volume of the ethanol base; benzene in an amount of about 3% to about 10% by volume of the ethanol base; and a lubricating oil component in an amount of about 2% to about 5% by volume of the ethanol base, said lubricating oil component being produced from sunflower seed, castor bean, safflower, or soybean.
Claim 10
Dependent Claim
92 words
A fuel comprising: an ethanol base having a composition by volume percent of about 70% to about 85% ethanol and about 30% to about 15% water; acetylene in an amount of about 4% to about 10% by volume of the ethanol base; benzene in an amount of about 3% to about 10% by volume of the ethanol base; and a lubricating oil component in an amount of about 2% to about 5% by volume of the ethanol base, said lubricating oil component being produced from sunflower seed, castor bean, safflower, or soybean.
Claim 11
Dependent Claim
12 words
The fuel of claim 1 wherein said volatile hydrocarbon component is propane.
Claim 12
Dependent Claim
17 words
The fuel of claim 1 wherein said volatile hydrocarbon component is 1-butene, 2-butene, or a mixture thereof.
Claim 13
Dependent Claim
12 words
The fuel of claim 1 wherein said volatile hydrocarbon component is butane.
