High oxygen operation of internal combustion engines

A kit for upgrading a vehicle having an internal combustion engine to use an alternative fuel, the kit comprising:

• an oxygen source that provides an oxygen-containing gas having at least 22 volume percent oxygen;
• a fuel injection system that includes a chamber for combining the oxygen-containing gas with the alternative fuel to form a combustible mixture, the fuel injection system configured to replace or supplement a vehicle's existing OEM fuel injection system;
• a conduit that is adapted to connect the fuel injection system to the internal combustion engine;
• and
• a generator adapted to be operated by the internal combustion engine to produce electricity for battery charging.

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, wherein the alternative fuel includes methanol in an amount from about 45 to 65 weight percent, water in an amount from about 20 to 40 weight percent, formaldehyde in an amount from about 1 to 8 weight percent, and 1,1-dimethoxyethane in an amount from about 1 to 7 weight percent.
