NOVELTY - Oxygen supply system has oxygen suppliers for engines, particle filters, oxygen generators using nanofilters, pressurized oxygen bottles and air compressors, loading the oxygen, or oxygen mixed with argon by bottles, cylinders or interchangeable tanks, recharging the oxygen, or oxygen mixed with argon by hoses, filtering by particle pre-filters, complementary nanomolecular membrane filters separating oxygen from air, carrying out separation through suction of the combustion engine or impulsion of a pump or compressor driven by an electric motor, storage unit for the separated or obtained oxygen for controlling the variable mixture of fuel/oxygen or air/oxygen by a processor or an engine control unit (ECU), compression and storage of the carbon dioxide of the exhaust gases, discharging the carbon dioxide and feedback for the carbon dioxide mixed with the engine fuel, once treated and converted into fuel, variable fuel control unit synthetic fuel, hydrocarbons, alcohols or hydrogen. USE - Oxygen supply system for internal combustion engines (claimed). ADVANTAGE - The system has improved the supply of oxygen, increases the power and producing great savings, economical, very useful, easy to apply, allows the use of renewable energies and is very ecological.
