NOVELTY - An apparatus and gas delivering system comprises hydrolyzer unit; a water-based electrolytic solution; internal plate assemblies including metallic-based plates; splash guards; pressure release valve; liquid-level sensor; a separate additional water reservoir; an atmospheric water recovery system based on process of dehumidification; a block heater unit; a dust-filtering attachment; a gas relay device; moisture collector; a modification of resistances on vehicle's computer; and computer-based sensors for measuring Greenhouse Gas emissions.    USE - As apparatus and gas delivering system for production of hydrogen and oxygen gases for use as a partial fuel source when added to fossil-based fuels used in operation of any internal combustion engine in e.g. small- and larger-scale applications and installations such as in motor vehicles, stationary applications, class 4-8 trucks and buses locomotive, large boats, which use internal combustion engines, such as stationary electrical generating stations (Gen-Sets), riding lawn mowers, fork-lifts, cars, vans, and pick-ups (claimed). Uses included but not limited to transportation stator e.g. police ambulance, locomotive marine sector e.g. marine vehicle, mining section e.g. large mining vehicles, farming sector e.g. tractor, warehousing operations including propane and natural gas powered fork-lift truck, and energy sector.    ADVANTAGE - The system produces hydrogen and oxygen gases by electrolysis in electrolyzer unit, on-demand and on-board a vehicle, or in stationary applications, eliminating the need of highly-pressurized hydrogen storage tanks. When the gases are introduced into the chamber of engine, they increase the efficiency of the combustion burn by enriching the air to fuel ratio, resulting in reduction of the fossil-based fuels required for optimum engine performance. The system is utilized in certain large-scale applications eliminating use of the vehicle's own battery. The hydrolyzer containment module constructed in a format that allows for storage of additional hydrolytic solution, in lower concentration levels, for extended operations thereby eliminating the need for an additional reservoir, heating system and power supply and incorporating internal splash guards and built-in moisture collector and moisture return for applications on e.g. truck tractors. The electrolytic solution partially fills the hydrolyzer containment module to cover the internal plate assemblies to maximize production of hydrogen and oxygen gases. The hydrolyzer unit is powered by a constant DC current in specific applications and controlled by a power supply pack; or the electrical output as controlled by the power supply pack, is adjusted automatically, dependent on the speed of the vehicle as dictated by the revolution per minute (RPM) of the engine, thereby increasing or reducing the amount of hydrogen and oxygen gases used as a partial fuel source when these gases enter into the combustion chambers, directly adjusting, and in proportion, reducing the amount of fossil fuels required for the operation of the internal combustion chamber. The system reduces emissions in various percentage of the mass or the composition of greenhouse gases as compared against a pre-measured baseline of particular individual gases, namely particulate matter or opacity (PM), nitrogen oxides, sulfur oxides, carbon monoxide, methane, and in particular in direct correlation to the reduction of fuel consumption, a near equivalent (99%) amount in reducing carbon dioxide emissions.    DETAILED DESCRIPTION - An apparatus and a gas delivering system for producing hydrogen and oxygen gases based on electrolysis of water, comprises hydrolyzer unit installed into air intake system of internal combustion engines. The hydrolyzer unit useful as partial fuel source when added to fossil-based fuel in the operation of internal combustion engine. The hydrolyzer unit and delivery system comprises a hydrolysis chamber functioning as a containment module; a water-based electrolytic solution comprised of steam distilled water, demineralized water or regular municipally-supplied tap water, together with an electrolytic agent, and for partially filling the chamber; at least one internal plate assembly including metallic-based plates, each interconnected in a manner that allows anode and cathode electrodes to be installed to the plate assemblies; at least one splash guard in the chamber; pressure release valve; liquid-level sensor with a remote light signal to alert user when level of water has reached the critical level inside the container and when the system requires additional water; optionally two separate float switches inside the container to maintain a safe water level; a direct current (DC) electrical charge; a separate additional water reservoir to allow for extended operation of the hydrolyzer; a screw or ratchet type tube clamp apparatus to mechanically lower the water pressure, and to regulates gravitational flow of water from the reservoir into the container at a rate approximately equal to the decreasing consumption rate of the water content of the water during electrolysis; an atmospheric water recovery system based on the process of dehumidification to extract moisture from surrounding air mass thus providing a continuous supply of water into the container, and including mechanical, gravity-based, automatically-operated valve and pre-determined feeder tube; a spiral-type arrangement of highly heat-conductive metal strips arranged in such a manner as to coil around exhaust pipe or engine manifold; a block heater unit inserted into the reservoir to keep the water from freezing when the vehicle is parked and an alternate current (AC) plug-in current is available; a dust-filtering attachment to a main box-type container to prevent dust and road dirt from penetrating the components of the container and other components including electrical connections and in certain applications; a gas relay device; a manually dischargeable moisture collector device containing a filtering substance to prevent moisture and hydrolytic agent contamination from entering the container, and having an exit valve for hydrogen and oxygen gases; a modification of resistances on vehicle's computer to allow for a leaner air to fossil-fuel mixture by adjusting vehicle's oxygen sensors and timing of the vehicle's fuel injector opening and closing sequences, allowing hydrogen and oxygen gases to enter into the combustion chambers and become a partial fuel source; and a cluster of computer-based sensors for measuring Greenhouse Gas emissions.
