Abstract: A method and apparatus is disclosed for enhancing the combustion efficiency of an internal combustion engine having one or more combustion chambers. The apparatus comprises an electrical power source having a voltage output, a power supply in electrical communication with output of the electrical power source, and an electrolytic cell having a cathode and an anode immersed in an aqueous electrolytic solution. The anode and the cathode are in electrical communication with the power supply output. The power supply optimizes the voltage output of the power source for use with the electrolytic cell. In turn, the electrolytic cell breaks down the aqueous solution into a mixture of hydrogen and oxygen gases which is conveyed to the combustion chamber of the engine.
