NOVELTY - The hydrogen generating device has a first generating unit for producing hydrogen, and a second generating unit for producing oxygen. The first generating unit includes an electrolytic separating unit (1) formed to distribute hydrogen and oxygen through their respective generation lines. The hydrogen is used in the combustion in conjunction with the oxygen received from the second generating unit to generate electrical currents (8a,8b) for use in the internal combustion engine, as well as residual water and air for re-supply to the electrolytic separating unit and for water supply cooling.    USE - Hydrogen generating device used in producing hydrogen for internal combustion engine. Can be used for gasoline engines.    ADVANTAGE - Addresses the technical problem of storing hydrogen, as well as the derived problems of using a substation to produce the fuel required to start and run the positive-ignition engine, increasing the working potential of the engine compared to operation with hydrocarbon and reducing residues to very low levels, clearly benefiting the environment. Provides a hydrogen generating device that produces hydrogen by electrolysis in internal combustion engine that does not need great fuel storage.    DETAILED DESCRIPTION - The distributed hydrogen passes through a first control valve (2) having two inputs, which include one main hydrogen input and one hydrogen return input. Hydrogen that is not used in the combustion process of an internal combustion engine or for storage in a hydrogen battery (7) is fed into the hydrogen return input. A hydrogen filter (3) is located before the input of the first control valve to control the pressure and volume of hydrogen before its passage through the carburetor (6) of an internal combustion engine. A temporary storage (4) and a pressure gauge (5) are provided for the hydrogen.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the hydrogen generating device.
