DETAILED DESCRIPTION - The improved hydrogen enhancement system/oxyhydrogen generator system comprises an electrolytic cell comprised of an electrolytic solution for the production of hydrogen gas and oxygen gas, a positive electrode plate, a negative electrode plate (23), a bipolar electrode plate, four rubber gaskets and set of constant pressure spring with bolts and nuts and connected to a frequency modulate pulse width modulator (FMPWM) power source, a d shape tube having an electrolytic solution tank, a moisture trap, a water fill plug, a fire back preventing system, a sludge trap, a foam trap, a gas outlet, a recycle gas tube, a gas delivery tube and an electrolytic deliver tube connected together in one piece, a d shape tube with generator installed in center of the d shape tube as complete set of system, an alkali and thermal resist fiber glass box (11) with tray (28) cover with controller box and equal angle, a controller system comprised of an alternator signal detector, a current detector, an automatic constant, a current adjuster, an over current protection, a frequency modulation pulse width modulator, an electronic power switch driver, an electronics power switch, a heat sink, an alternator, a battery and a control switch, a constant pressure spring to prevent electrolytic solution leak, a sludge trap to collect the sludge from generator, a natural electrolytic solution circulation of system and natural electrolytic solution, a moisture trap system, a foam trap system, a fire back preventing system, a water fill up with moisture trap, and a unit to adjust the fuel flame speed of the hydrogen oxygen fuel produced in the electrolytic cell. The hydrogen and oxygen gas collect at a gas collection upper chamber of generator pass thru fire back preventing system to recycle gas tube and send to moisture trap, a unit to remove moisture from the gas, a unit to protect the gas from backfire, a unit to trap foam in the foam trap, a unit to cool fluids contained in the storage tank without electrical fan, a unit to circulate the fluids contained in the storage tank without electrical fluid pumps, a unit to fill up water without disturbed the gas outlet and gas production of the system, and a unit to collect the sludge at lower part of the sludge trap and a chamber filled with the electrolytic solution to a level adequate for the effective functioning of the system. The d shape tube with generator of the system is installed in alkali and thermal resist fiber glass box with tray under box to protect leakage of electrolytic solution, and is used as support for generator system to engine frame. A controller (24) is installed with aluminum plate (26) as support and heat sink attach on top of box cover and protect the system by equal angle from opened. The alkali and thermal resist fiber glass box prevents electrocution, impact, support, and electrolytic solution leak. The production of hydrogen gas and oxygen gas depend on the revolutions per minute (RPM) of alternator, a unit to low RPM low oxyhydrogen production and low current consumption in the system, a unit to high RPM high oxyhydrogen production and high current consumption in the system, a unit to use FMPWM of direct current (DC) only in the system, a unit to protect over current in the system, a unit to control constant current of the system, a unit to use aluminum plate as controller support, a controller protection, and a heat sink of the system. The constant pressure spring is comprised of a spring, a bolt, a lock nut, and a washer. The sludge trap separates clean electrolytic solution from sludge, and collects under the generator. The clean electrolytic solution delivers to the bottom of generator by electrolytic solution deliver tube, and cleans surface electrode transfer oxyhydrogen to gas collector chamber inside the generator. The moisture trap separates water fill from gas generate.    DESCRIPTION OF DRAWING(S) - The diagram shows an isometric view of an oxyhydrogen generator system of alkali and thermal resist box.
