1. A method for operating an internal combustion engine, the method comprising:
providing an oxygen-containing gas having greater than 22 volume percent oxygen;
combining the oxygen-containing gas with an alternative fuel to form a combustible mixture; and
directing the combustible mixture to the internal combustion engine wherein combustion of the combustible mixture drives the internal combustion engine, wherein the internal combustion engine is configured to operate for direct or indirect propulsion of an on or off road vehicle, direct or indirect propulsion of marine vessels, power generation, or industrial and agricultural pumping-pumping, wherein the alternative fuel includes 0 to 15 mole percent acetone, 30 to 99 mole percent methanol, 0 to 20 mole percent ethanol, 0.0 to 10 mole percent isopropanol, 0 to 1 mole percent acetic acid, 0 to 1 mole percent formic acid, 0 to 15 mole percent formaldehyde, and 1 to 30 mole percent water.
