Abstract
Abstract An improvement to an internal combustion engine having a fuel system for feeding a fuel-air mixture to the combustion chambers and an electrical generation system, such as an alternator. An electrolytic cell is attached adjacent to the engine to generate hydrogen and oxygen upon the application of a voltage between the cathode and anode of the electrolytic cell. The gas feed connects the electrolytic cell to the engine fuel system for feeding the hydrogen and oxygen to the engine combustion chambers. Improvements include placing the electrolytic cell under a predetermined pressure to prevent the electrolyte from boiling off, a cooling system for the electrolytic cell and safety features.
