Abstract
Abstract This invention discloses a method for improving fuel economy and at the same time reducing pollutants caused by the use of oil as a fuel, which comprises combusting said oil in the form of an oil-water emulsion, in which said oil-water emulsion is effected by admixing a mixture comprising oil and water with dextrin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A method for saving bunker-c oil for use as a fuel and reducing pollution caused by the use thereof, which comprises combusting said bunker-c oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65% or more oil and 35% or less water with dextrin; said dextrin being added in an amount of between about 0.5 and about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 2
Independent Claim
79 words
A method for saving bunker-c oil for use as a fuel and reducing pollution caused by the use thereof, which comprises combusting said bunker-c oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65% or more oil and 35% or less water with dextrin; said dextrin being added in an amount of between about 0.5 and about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 3
Dependent Claim
25 words
The method of claim 1 in which said mixture of oil and water comprises 80 percent or more oil and 20 percent or less water.
Claim 4
Independent Claim
83 words
A method for increasing heat efficiency of bunker-c oil for use as a fuel and reducing pollution caused by the use thereof, which comprises combusting said oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65 percent or more oil and 35 percent or less water with dextrin; said dextrin being added in an amount of between about 0.5 to about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 5
Independent Claim
83 words
A method for increasing heat efficiency of bunker-c oil for use as a fuel and reducing pollution caused by the use thereof, which comprises combusting said oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65 percent or more oil and 35 percent or less water with dextrin; said dextrin being added in an amount of between about 0.5 to about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 6
Dependent Claim
25 words
The method of claim 3 in which said mixture of oil and water comprises 80 percent or more oil and 20 percent or less water.
Claim 7
Independent Claim
84 words
A method for reducing pollution caused by the use of bunker-c oil as a fuel and reducing pollution caused by the use thereof, which comprises combusting said oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65 percent or more oil and 35 percent or less water with dextrin; said dextrin being added in an amount of between about 0.5 and about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 8
Independent Claim
84 words
A method for reducing pollution caused by the use of bunker-c oil as a fuel and reducing pollution caused by the use thereof, which comprises combusting said oil in the form of an oil-water emulsion, wherein said oil-water emulsion is effected by admixing a mixture comprising 65 percent or more oil and 35 percent or less water with dextrin; said dextrin being added in an amount of between about 0.5 and about 15 parts by weight per 1000 parts by weight of said mixture.
Claim 9
Dependent Claim
25 words

Claim 10
Dependent Claim
57 words
An emulsified oil composition suitable for use as a fuel to reduce pollution caused by the use of bunker-c fuel oil which comprises a mixture of 65 percent or more bunker-c oil and 35 percent or less water and about 0.5 to about 15 parts by weight of dextrin per 1000 parts by weight of said mixture.
Claim 11
Dependent Claim
57 words
An emulsified oil composition suitable for use as a fuel to reduce pollution caused by the use of bunker-c fuel oil which comprises a mixture of 65 percent or more bunker-c oil and 35 percent or less water and about 0.5 to about 15 parts by weight of dextrin per 1000 parts by weight of said mixture.
