Abstract
Abstract For the improved combustion of hydrocarbon compounds, for example those contained in gasoline, diesel fuel etc., in internal combustion engines a liquid composition comprising hydrogen peroxide, water, aliphatic alcohol having 1-4 carbon atoms, and preferably thin lubricating oil and anticorrosive is admixed with the fuel air mixture in the internal combustion engines.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A method of improving the combustion of fuel containing hydrocarbon compounds in the combustion chamber or chambers of internal combustion engines in order to reduce fuel consumption and diminish the content of impurities in the exhaust gases of the engine, comprising introducing a liquid composition consisting essentially of 1-10% hydrogen peroxide, 50-80% water, and 15-45% of a C 1-4 aliphatic alcohol, all by volume, in the form of fine droplets, into the air intake manifold of the internal combustion engine, the air or fuel air mixture in said intake manifold being intimately mixed with the fine droplets of said liquid composition so that said air or said fuel air mixture on entering said combustion chamber contains said liquid composition.
Claim 2
Independent Claim
119 words
A method of improving the combustion of fuel containing hydrocarbon compounds in the combustion chamber or chambers of internal combustion engines in order to reduce fuel consumption and diminish the content of impurities in the exhaust gases of the engine, comprising introducing a liquid composition consisting essentially of 1-10% hydrogen peroxide, 50-80% water, and 15-45% of a C 1-4 aliphatic alcohol, all by volume, in the form of fine droplets, into the air intake manifold of the internal combustion engine, the air or fuel air mixture in said intake manifold being intimately mixed with the fine droplets of said liquid composition so that said air or said fuel air mixture on entering said combustion chamber contains said liquid composition.
Claim 3
Dependent Claim
15 words
A method as claimed in claim 1, wherein said liquid composition also contains an anticorrosive.
Claim 4
Dependent Claim
13 words
A method as claimed in claim 1, wherein said aliphatic alcohol is ethanol.
Claim 5
Dependent Claim
30 words
A method as claimed in claim 1, wherein said liquid composition comprises 3-7% hydrogen peroxide, 60-75% water, 32-17% ethanol, up to 5% thin lubricating oil and up to 1% anticorrosive.
Claim 6
Dependent Claim
26 words
A method as claimed in claim 1, wherein said liquid composition comprises 4% hydrogen peroxide, 63% water, 27.9% ethanol, 5% thin lubricating oil and 0.1% anticorrosive.
Claim 7
Dependent Claim
20 words
A method as claimed in claim 1, wherein the liquid composition comprises 2-15% lubricating oil and up to 5% anticorrosive.
