Abstract

A gasoline additive concentrate composition comprises a solvent, an alkoxylated fatty amine, and a partial ester having at least one free hydroxyl group and formed by reacting at least one fatty carboxylic acid and at least one polyhydric alcohol. A fuel composition comprises gasoline and the gasoline additive concentrate composition. A method of operating a gasoline internal combustion engine comprises fueling the engine with the fuel composition and is effective in reducing fuel consumption.

Claims

1. A gasoline additive concentrate composition, comprising:

a solvent that is an aromatic hydrocarbon, a mixture of an alcohol and an aromatic hydrocarbon, or a mixture of an alcohol and a kerosene having some aromatic content;

an alkoxylated fatty amine represented by the formula

2. The composition of claim 1 wherein the alkoxylated fatty amine is a diethoxylated fatty amine having about 16 to 18 carbon atoms.

3. The composition of claim 1 wherein the fatty carboxylic acid has about 4 to 30 carbon atoms.

4. The composition of claim 1 wherein the fatty carboxylic acid is a saturated aliphatic monocarboxylic acid or an unsaturated aliphatic monocarboxylic acid.

5. The composition of claim 1 wherein the fatty carboxylic acid is oleic acid.

6. The composition of claim 1 wherein the polyhydric alcohol is glycerol or ethylene glycol.

7. The composition of claim 1 wherein the partial ester is a mixture of glycerol monooleate and glycerol dioleate.

8. The composition of claim 1 wherein the polymeric pour point depressant is a terpolymer formed by polymerizing a dialkyl fumarate, a vinyl carboxylate, and a vinyl ether.

9. A fuel composition, comprising:

gasoline; and

the gasoline additive concentrate composition of claim 1.

10. A method of operating and reducing the fuel consumption of a gasoline internal combustion engine comprising fueling the engine with the fuel composition of claim 9.

11. A gasoline additive concentrate composition, comprising:

a solvent that is an aromatic hydrocarbon, a mixture of an alcohol and an aromatic hydrocarbon, or a mixture of an alcohol and a kerosene having some aromatic content;

an alkoxylated fatty amine represented by the formula

12. The composition of claim 11 wherein the polyetheramine is formed by hydrogenating a nitrile which is prepared by reacting a polyalkoxylated alcohol or alkylphenol and acrylonitrile.

13. A fuel composition, comprising:

gasoline; and

the gasoline additive concentrate composition of claim 11.

14. A method of operating and reducing the fuel consumption of a gasoline internal combustion engine comprising fueling the engine with the fuel composition of claim 13.

15. The composition of claim 11 wherein the mixture of two or more nitrogen-containing detergents comprises a polyetheramine and a Mannich reaction product.
