Fuel and fuel blend for internal combustion engine

DWPI Title: Powering internal combustion engine by combusting fuel to drive piston in cylinder of engine in which fuel comprises minority portion of ketone-based blending agent and majority portion containing e.g. gasoline, diesel, and/or alcohol fuel
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.
Use: The method is useful for powering an internal combustion engine, i.e. low-temperature gasoline combustion engine, temperature combustion diesel engine, or homogeneous charge compression ignition engine (claimed).
Advantage: The ketone compound may be derived from biological sources. The lower reactivity (indicative of a higher RON) that the ketone-based compounds provide can enable engines to run with higher compression ratios (CR), which can increase efficiency and/or power density.
Novelty: An internal combustion engine is powered by combusting a fuel to drive a piston in a cylinder of the engine, where the fuel comprises a minority portion of a ketone-based blending agent selected from 4-10C branched acyclic ketone, cyclopentanone, or a derivative of cyclopentanone, and a majority portion of a fuel selected from gasoline, diesel, alcohol fuel, biofuel, renewable fuel, and/or Fischer-Tropsch fuel. The engine is not a spark ignition engine and is a low-temperature gasoline combustion engine or a homogeneous charge compression engine. Majority portion of the fuel is present in a ratio of 95:5-51:49 by volume of the ketone-based blending agent.
