As you would expect with all statistical Bell Curve distributions, there occur the occasional unexpectedly good results, e.g., more than 75% increase in fuel economy (mpg).  Obviously, the other end of that same statistical Bell Curve distributions include those motor vehicles which do not achieve increased fuel economy.  Usually, these are the result of faulty installation as the science of using electrolysis to create Brown’s Gas (H.H.O.) and the use of Brown’s gas (H-H-O) to increase fuel economy is certain and straight-forward.  These unexpectedly bad situations are handled by either giving the customer a Money Back Guarantee or by re-installing the Hydrogen on Demand (H.O.D.) fuel supplement system to correct the problem(s) that resulted in no noticeable increase in mpg fuel economy.

Brown’s gas is named after the electrical engineer Yull Brown (1922 – 1998) who emigrated to Australia from his homeland, Bulgaria, where he was born Ilya Velbov.  In 1974, Yull Brown filed a patent of his Brown’s gas electrolyzer which was a proprietary method of water electrolysis that yields a non-explosive mixture of hydrogen and oxygen gas in the precise (+/– 5%) ratio of 2 hydrogen atoms to 1 oxygen atom (H-H-O which precise gas ratios are called “stoichiometric mixes”).  Yull Brown was experimenting with finding safe gases to weld dissimilar materials (brick to steel).  Brown’s gas (H-H-O) safely permits the more efficient burning (“exploding”) of gas or diesel fuel that increases the fuel-burning efficiency of auto engines by 20% - 50% in general.

Yull Brown was one of the many scientists whose efforts have led to the present Hydrogen on Demand (H.O.D.) fuel supplement kits.  In 1832, Michael Faraday discovered the laws of electrolysis and he was able to separate hydrogen from water by using electricity.  In 1894 Brown’s Gas (H-H-O) was known as “Knalgas” which was used to melt platinum.  In 1935 Henry Garret patented an electrolytic carburetor which used water as the fuel to power automobiles.  In 1962, William Rhodes (Brown’s gas is sometimes called “Rhodes gas”.) filed a patent for a single-ducted electrolyzer gas (H-H-O).   

The chemical energy into mechanical energy conversion upon which H-H-O fuel supplement kits depend is simple and straight-forward.  The fuel supplement kit uses electrolysis of the distilled water – electrolyte to create Brown’s gas (H.H.O.) from the liquid form into gas H-H-O.  This Brown’s gas (H-H-O) is then delivered to the fuel injection system via vacuum lines which connect the hydrogen generator(s) to the air-intake system.  The introduction of this Brown’s gas (H-H-O) into the fuel supply generates more power to the piston-powered torque of the engine by causing the fuel to be “exploded” more efficiently.  This process can be explained (over-simply) as:

-- Hydrogen is the smallest size molecule of all the elements in the Periodic Table of Elements and hydrogen is very combustible and moves more rapidly through gas than other gas molecules.

 --  Thus hydrogen molecules mingle easily and rapidly with the fuel injector fuel-to-air mix to create more “explosions” in the same volume of fuel and in the same amount of time needed to “explode” the fuel-to-air mixture in the piston cylinders of the engine.

 --  Because motor vehicle combustion engines achieve an efficiency of perhaps 25% of the potential energy contained in that volume of fuel-to-air supplied to the piston cylinder chambers via the fuel injectors, the addition of hydrogen molecules and oxygen molecules increases the number and speed of the “explosions” that power the engine.  That is, the efficiency of burning fuel in the piston cylinders is increased because the amount of fuel actually “exploded” to power the motor vehicle is increased.

-- The “glitches” which can occur often result from the Oxygen Sensor(s) in the exhaust manifold “reading” the increase in the amount of oxygen in the exhaust gas at the exhaust manifold (which oxygen increase is the result of more efficient burning of the fuel in the piston cylinders) as being the result of “too lean” a fuel-to-air mixture going into the fuel injectors.  Therefore, the Oxygen Sensor(s) signal the ECM (electronic control module, the “brains” of an engine) to go into its default program and “dumping” fuel into the fuel injectors.  This, of course, defeats the purpose of installing fuel efficient H-H-O systems.  Thus, the “art” of keeping the motor vehicle burning (“exploding”) its fuel supply more efficiently is to control the electric signal from the Oxygen Sensor(s) to the ECM (which is a voltage measurement between 0 and 1 volt, usually less than 0.45 volts).  There are many theories and devices used to accomplish this.

All the various H-H-O fuel economy systems are based on the science sketched above and almost all of the devices and inventions used are “in the public domain” and therefore there are no patent infringements when the various suppliers of the H-H-O fuel supplement kits sell these products to the public.
