Electrolyzed hydrogen gas enhancement of hydrocarbon fuel combustion

A system for hydrogen-oxygen gas enhancement of hydrocarbon fuel combustion comprising:

• a closed electrolyzer vessel in which water is circulated from a water circulation port at a water level to be maintained in said electrolyzer vessel and returned via a water return line into a return port at the bottom of the vessel,
• an electrode plate assembly comprised of a series of plates, including cathode plate, anode plate, and inner plates arranged in parallel, which is mounted in a lower part of the vessel and immersed in water below the water level maintained in the vessel,
• wherein the electrode plate assembly has a voltage applied across cathode and anode plates thereof to dissociate water into constituent hydrogen and oxygen gases which are collected in an upper part of the vessel and inducted from an output port of the vessel to an air intake for hydrocarbon combustion,
• wherein an air injector is arranged in the water return line into the vessel to inject air in the water flow for causing air bubbling in the water supplied between and around the electrode plate assembly, and
• wherein only water is used as the electrolyte fluid without any additives.
