NOVELTY - The control system has water electrolysis chamber (110), power supply (130), solid state power switches (108) connected between power supply and water electrolysis chamber through monitoring resistor (104), first connection to supply voltage across monitoring resistor, second connection to supply voltage to offset adjustor (116), fourth connection to supply combined voltage from offset adjustor to second input of voltage comparator (120), and fifth connection from comparator to power switches which supply pulsed DC to chamber and maintain pulsed DC at or below desired current magnitude.    USE - Control system for production of gas by water electrolysis chamber using pulsed DC in mobile hydrogen gas device, such as hydrogen and oxygen gas injected into internal combustion engine of motor vehicle.    ADVANTAGE - Regularly clears electrolyzing sites on the electrodes of hydrogen and oxygen gas during electrolysis in order to sustain maximum contact of electrolyzing sites with water molecules, to effectively electrolyze water to its hydrogen and oxygen components, by cost-effectively applying pulsed current to the electrodes, allowing the gas molecules to rise and separate away from electrolyzing sites between current pulses. Generates hydrogen and oxygen in Liters per Minute production volumes from small chambers, by applying pulsed current. Various energy delivery pulse widths allow for the adjustment of delivered power at high electrical conversion efficiencies. Full power start up during initial, cool chamber state allows for quicker and greater production of gas, and using greater amount of gas for cold internal combustion engine helps reduce emission of pollutants from the engine.    DETAILED DESCRIPTION - The solid state power switches comprises semiconductor switches, such as MOSFET switches. A temperature sensor receives temperature information from water electrolysis chamber. A detector detects if internal combustion engine is operating. A sensor monitors volume of gas production in electrolysis chamber.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic circuit block diagram of a current regulating device that controls or regulates current provided to electrolysis chambers that produce hydrogen and oxygen gases, showing an added circuit to indicate various chamber states.
