Abstract

A hydrocarbon fuel is described comprising a hydrocarbon fuel boiling in the gasoline boiling range containing not greater than about 5 wppm nitrogen. The lubricity of such fuel is improved by the addition thereto of ethanol.

Claims (39)

1. A fuel composition comprising ethanol and a hydrocarbon base fuel boiling in the gasoline boiling range and suitable for use in a spark ignition internal combustion engine which hydrocarbon base fuel has a nitrogen content, exclusive of nitrogen attributable to additives, of about 5 wppm or less.
2. The fuel of claim 1 wherein the nitrogen content is about
3 wppm or less.
3. The fuel of claim 1 wherein the nitrogen content is about 2 wppm or less.
4. The fuel of claim 1 wherein the nitrogen content is about 0.5 wppm or less.
5. The fuel of claim 1, 2, 3 or 4 wherein the hydrocarbon base fuel is further characterized as having a sulfur content of about 50 wppm or less.
6. The fuel of claim 1, 2, 3 or 4 wherein the hydrocarbon base fuel is further characterized as having a sulfur content of about 10 wppm or less.
7. The fuel of claim 1, 2, 3 or 4 wherein the hydrocarbon base fuel is further characterized as having a sulfur content of about 5 wppm or less.
8. The fuel of claim 1, 2, 3 or 4 wherein the amount of ethanol present is at least about 2 vol%.
9. The fuel of claim 1, 2, 3 or 4 wherein the amount of ethanol present is at least about 5 vol%.
10. The fuel of claim 1, 2, 3 or 4 wherein the amount of ethanol present is about 5-15 vol%.
11. The fuel of claim 5 wherein the amount of ethanol present is at least about 2 vol%.
12. The fuel of claim 6 wherein the amount of ethanol present is at least about 2 vol%.
13. The fuel of claim 7 wherein the amount of ethanol present is at least about 2 vol%.
14. The fuel of claim 5 wherein the amount of ethanol present is at least about 5 vol%.
15. The fuel of claim 6 wherein the amount of ethanol present is at least about 5 vol%.
16. The fuel of claim 7 wherein the amount of ethanol present is at least about 5 vol%.
17. The fuel of claim 5 wherein the nitrogen to sulfur weight ppm ratio is about 0.01:1 to 1:1.
18. The fuel of claim 1, 2, 3 or 4 further characterized as having a Reid Vapor Pressure of less than about 9 psi.
19. A method for improving the lubricity of hydrocarbon fuel boiling in the gasoline boiling range and suitable for use in a spark ignition internal combustion engine comprising a base fuel having a base fuel nitrogen content of about 5 wppm or less nitrogen, exclusive of nitrogen attributable to additives, by adding to said fuel at least about 2 vol% ethanol.
20. The method of claim 19 wherein the fuel contains about 3 wppm or less of nitrogen.
21. The method of claim 19 wherein the fuel contains about 2 wppm or less of nitrogen.
22. The method of claim 19 wherein the fuel contains about 0.5 wppm or less of nitrogen.
23. The method of claim 19, 20, 21 or 22 wherein the base fuel is further characterized containing about 50 wppm or less of sulfur.

34. The method of claim 23 wherein the nitrogen to sulfur weight ppm ratio of the fuel is about 0.01:1 to 1:1.
35. The method of claim 17, 18, 19 or 20 wherein the fuel is further characterized as having a Reid Vapor Pressure of less than about 9 psi.
36. A low sulfur base gasoline suitable for use as an oxygenated gasoline base stock comprising a base gasoline having a nitrogen content of about 5 wppm or less nitrogen, the base gasoline subsequently blended with at least about 2 vol% ethanol to thereby enhance the lubricity of said gasoline.
37. The base gasoline of claim 36 wherein the gasoline is subsequently blended with at least about 5 vol% ethanol.
38. A method for operating an internal combustion engine contain-ing fuel system assemblies requiring lubrication including submerged fuel pump, fuel injectors, or both by supplying to said engine a fuel comprising gasoline containing about 5 wppm or less nitrogen and at least about 2 vol% ethanol.
39. The fuel composition of claim 1, 2, 3 or 4 further containing gasoline additives.
