Abstract

A fuel or fuel blending agent for an internal combustion engine includes a ketone compound that is a C 4 to C 10 branched acyclic ketone, cyclopentanone, or a derivative of cyclopentanone. The ketone compound may be blended with a majority portion of a fuel selected from the group consisting of: gasoline, diesel, alcohol fuel, biofuel, renewable fuel, Fischer-Tropsch fuel, or combinations thereof. The ketone compound may be derived from biological sources. A method for powering an internal combustion engine with a fuel comprising the ketone compound is also provided.

Claims (22)

1. An enhanced fuel for an internal combustion engine comprising:

a majority portion of a fuel selected from the group consisting of: gasoline, diesel, alcohol fuel, biofuel, renewable fuel, Fischer-Tropsch fuel, and combinations thereof; and

a minority portion of a blending agent;

wherein the blending agent includes a ketone-based blending agent that is a derivative of cyclopentanone corresponding to formula I:

wherein each R group is independently selected from H, CH 2 CH 3 , or CH 3 , and at least one R is CH 2 CH 3 or CH 3 ;

wherein the blending agent is exclusive of an amide;

wherein the majority portion of the fuel is present in a ratio of 95:5 to 51:49 by volume of the ketone-based blending agent.

2. The enhanced fuel of claim 1 , wherein the majority portion is gasoline or a blend of gasoline and ethanol.

3. The enhanced fuel of claim 1 , wherein the majority portion of the fuel has a research octane number of 50 to 150.

4. The enhanced fuel of claim 3 , wherein the enhanced fuel has a research octane number 5 to 100% higher than the research octane number of the majority portion of the fuel.

5. An enhanced fuel for an internal combustion engine comprising:

a majority portion of a gasoline or blend of gasoline and ethanol; and

a minority portion of a blending agent;

wherein the blending agent includes a ketone-based blending agent that is cyclopentanone or a derivative of cyclopentanone;

wherein the majority portion of the fuel is present in a ratio of 95:5 to 51:49 by volume of the ketone-based blending agent.

6. The enhanced fuel of claim 5 , wherein the derivative of cyclopentanone corresponds to formula I:

wherein each R group is independently selected from H, CH 2 CH 3 , or CH 3 , and at least one R is CH 2 CH 3 or CH 3 .

7. The enhanced fuel of claim 1 , wherein the majority portion of the fuel is diesel fuel.

8. The enhanced fuel of claim 1 , wherein the fuel includes gasoline and the ketone-based blending agent is present in the enhanced fuel in an amount of 20 to 40% by volume.

9. The enhanced fuel of claim 5 , wherein the blending agent is exclusive of an amide.

10. The enhanced fuel of claim 5 , wherein the majority portion of the fuel has a research octane number of 50 to 150.

11. The enhanced fuel of claim 10 , wherein the enhanced fuel has a research octane number 5 to 100% higher than the research octane number of the majority portion of the fuel.
