NOVELTY - Device based on complete internal-combustion engine comprises an electrolytic groove (7) of vehicle-carried battery (11). The released oxygen is transported by an oxygen transporting pipe (9.1). The released hydrogen is transported by hydrogen transporting tube (9). The upper portion of the hydrogen transport tube is provided with one-way valve (17). The upper portion of the oxygen transport tube is provided with one-way valve (18). The device based on complete internal-combustion engine comprises an electrolytic slot for taking water in electrolytic cell for separating out released oxygen.    USE - Device based on complete internal-combustion engine.    ADVANTAGE - The device based on complete internal-combustion engine eliminates 90% pollution source from the vehicle. Thus, the device promotes complete combustion, in an economical and environment-friendly manner too.
