SYSTEM AND METHOD FOR USING CONCENTRATED OXYGEN FOR GAS INTAKE INTO AN INTERNAL COMBUSTION ENGINE

Methods and systems for enhancing fuel combustion in an engine (which may be a standard gasoline engine, a diesel engine or a hydro-diesel engine) by using an oxygen concentrator to remove nitrogen from the air to produce a concentrated oxygen gas that is fed into a gas intake of the engine's combustion chamber. The concentrated oxygen gas and liquid fuel are combusted within the combustion chamber. In hydro-diesel embodiments, hydrogen gas is mixed into the liquid diesel fuel to form a homogeneous mixture of hydrogen gas and liquid diesel fuel entering the combustion chamber. Filler gases may also be added into the combustion chamber.
