Abstract
A fuel or fuel blending agent for an internal combustion engine includes a ketone compound that is a C4 to C10 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.
Claims20
A method for powering an internal combustion engine, comprising:
- combusting a fuel to drive a piston in a cylinder of the engine;
- wherein the fuel comprises a minority portion of a ketone-based blending agent selected from a C4 to C10 branched acyclic ketone, cyclopentanone, or a derivative of cyclopentanone and 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;
- wherein the engine is not a spark ignition engine and is a low-temperature gasoline combustion engine or homogenous charge compression engine;
- 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.
