Answers to Many HHO Questions...

HHO hydrogen powered space shuttleWhy Hydrogen Energy?

"Hydrogen has the highest energy to weight ratio known, NASA has used it as a rocket fuel for decades.

If you watch a shuttle lift off you can see that the three rockets attached to the shuttle itself have a blue flame.

That is the space shuttle on board hydrogen rocket. The booster rockets utilize liquid hydrogen, combined with oxygen for their fuel. In addition, NASA uses hydrogen for its primary fuel while out in space.

Hydrogen is also used for making drinking water in outer space, one kg of hydrogen, combined with oxygen, will make nine kg of pure drinking water."

Hydrogen is considered a near-perfect energy carrier. It has many advantages over conventional fuels: it is non-toxic, it is renewable, clean to use, it's cheap, and it produces much more energy per kg. Hydrogen is considered the fuel of choice for energy-efficiency. As stated above, it burns very cleanly and doesn't produce hydrocarbon pollutants.

Huge Industrial Dry Cell HHO Generator

Hydrogen & Oxygen automatically separated

One of the most exciting things about hydrogen is that it is virtually cost free since one can extract hydrogen from water (one liter of water will produce approximately 2000 liters of hydrogen and oxygen). You just have to separate the hydrogen from the oxygen in the water.

Exactly how does the HHO Generator work?hoffman-apparatus HHO separation of hydrogen and oxygen HHO generator

The HHO Generator sends an Electric Charge through a liquid electrolyte comprised of distilled or tap water and potassium Hydroxide (KOH), which causes the hydrogen molecules to separate from the oxygen molecules in the water. It then captures the pure hydrogen and oxygen and transports the 2 gases (HHO) into the engine via the air intake system.

Will a HHO generator work in my vehicle?

A HHO generator will work in any conventional motor vehicle with an internal combustion engine, gasoline, propane, natural gas, or diesel and/or bio-diesel fueled. If your car or truck has an internal combustion engine that burns gasoline, propane, natural gas, or diesel or bio-diesel fuel, you can reap significant mileage benefits and financial savings from a HHO Generator!

In all post 1996 fuel injected, gas powered, computerized vehicles with a HHO Generator installed, the electrolyzed HHO is drawn into the air intake mixed with the ambient air, past the mass air flow sensor which tells the computer how much air volume is flowing into the engine. This allows the onboard computer to set the fuel/air mixture (No MAP sensor adjustment is required). The HHO is then drawn into the internal combustion cylinder where it accelerates the ignition of the liquid fuel. The resultant remains are then ejected out of the combustion cylinder exhaust valve ports where the exhaust sensors test the exhaust content and forward the data to the onboard computer.

HHO Dry Cell vs. Wet Cell?

Why is the HHO Dry Cell a better design?

                  Dry Cell                                                    Wet Cell

Here are 3 important reasons:

1. When the edges of the plates of a HHO generator are submerged in the water/catalyst bath a great deal of the electrical current passes through the edges of the plates. This current is largely wasted in terms of HHO production. When the edges are outside of the bath, as with the HHO dry cell, all of the current is forced to travel directly to the faces of the plates. Therefore all of the current supplied to the HHO generator is utilized, efficiently making HHO gas. This is the main reason the HHO dry cell design has become so popular.

2. The electrolyte bath attacks and will eventually destroy the electrical connections if they are submerged. With the HHO dry cell design they are outside of the water/catalyst solution.  The electrolyte also recirculates through an outside electrolyte tank which helps by washing gas off the plates and also dissipating heat to the electrolyte tank, producing more HHO gas and less heat (steam).

3. Because it is efficient, there is not a lot of wasted space and electrolyte solution that is not being used and charged with current. The very small volume of electrolyte solution that enters the HHO dry cell is subjected to electrical current and able to react and create HHO gas, then exit the HHO dry cell generator and recirculate.

The plates of our HHO dry cells are made of 316L stainless steel. This has been found to have the best properties of resistance to attack from the process of electrolysis. Mounting hardware and wire and cable are very difficult to find in 316L grade and are very costly to use. With the HHO dry cell design, all of these connections are outside of the electrolyte so this isn't an issue.

Dry cells operating in a "closed" system as we employ, run cooler, because the electrolyte is circulating throughout the system and dissipates the heat more efficiently than the old "wet bath" cells. Our electrical current limiters (PWM) also cap the amperage at designed levels to prevent heat "thermal runaway", as often happens in the old "wet bath" cells.

What Kind of HHO cell do you think this one is?

hho dc3000


It says dry cell and it looks like a dry cell, but we really can't be sure because the manufacturer has hidden the plates from view, and in doing so has also insulated them, effectively trapping the heat inside (bad idea #1).

Bottom line is a well-designed dry cell doesn't use bolts to transfer power to the plates, but powers the plates directly. These bolt connections and the inside transfer connections to the plates will heat up and expand, and will eventually loosen due to the expansion and contraction, and they will eventually fail. The loose electrical connections will eventually increase electrical resistance which will cause the bolts to get hotter (I've seen them red hot before), which will decrease voltage across the plates resulting in lower gas production. The internal connections can even get so loose as to cause a spark and if that happens the cell will explode (bad idea #2).  

Why do we use 316L grade stainless steel plates?

316L Stainless Steel sheets laser cut into HHO platesGrade 316L is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316L better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It also has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316L also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections. Grade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

Electronic Fuel Injection/O2 Sensor Mitigation.

Fuel injection o2-oxygen sensor mitigation for HHO

Post-1996 gasoline engines with Electronic Fuel Injection (EFI) will have mileage-resistant O2 sensors mounted in the exhaust manifold or just in front of the catalytic converter. In-line 4 or 6 cylinder engines will generally only have a single O2 sensor, V-6, V-8, and V-10 engines will usually have two O2 sensors. In order to achieve the full benefits of the HHO input from the HHO Generator, or any supplemental HHO generator, most post-1996 vehicles with EFI gasoline engines will need to install a small electronic signal interceptor called an EFIE device, which allows for the manual adjustment or "masking" of the signal the O2 sensor sends to the onboard computer after the HHO Generator is installed.

These government-mandated O2 sensors are mileage-resistant. The sensors read the cleaner exhaust produced with the HHO added to the air-intake as a "lean" mixture, because it contains less of the pollutants normally sensed from the burning of carbon-based fuels alone. The "lean mixture" signal it relays to the onboard computer will instruct the onboard computer to inject more fuel into the combustion process, thus undoing the benefits of the added hydrogen and oxygen input. These small EFIE devices are available for both single and multiple sensor vehicles.

Diesel engines don't currently have O2 exhaust sensors that control the fuel supply by assessing the oxygen content of the exhaust gases. Both the electrolyzed hydrogen and oxygen (HHO) can be introduced into the air-intake of diesel powered engines without the mitigating techniques needed by post-1996 fuel-injected gasoline driven engines, such as O2 extension fitting or EFIE devices.

Installing the HHO Generator does not require any modifications to your engine. All you have to do is route the HHO transmission hose from the HHO Generator to the engine air-intake cowling. It takes a qualified mechanic about 1 hour to install the HHO Generator. (Recommended)

Will a HHO Generator work on Diesel Engines?

Absolutely! A HHO generator will work well on any diesel engine. The fact of the matter is the improvement in fuel economy for diesel engines is much better that gasoline engines. Most Diesel engines burn less than 55% of the fuel injected and the rest comes out as pollution. Ever wonder why your exhaust emits black smoke? HHO provides the catalyst necessary for the full combustion of Diesel significantly reducing the contaminants that plug downstream filters.

 What about my Mass Air Flow (MAF) and my Manifold Absolute Pressure (MAP) Sensor?

Mass Air Flow Meter-MAF and MAP sensor HHO generator compatibility

The mass air flow (MAF) sensor responds to the volume of gas/air flowing through the chamber containing the sensor. It is intended to be insensitive to the density of the gas/air. Thus there is no need to mitigate/adjust/or mess around with your MAF when you install the Hydrogen Generator.

A manifold absolute pressure sensor (MAP) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected and gasoline powered. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a MAF (mass air flow) sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both. Once again, there is no need to mitigate/adjust/or mess around with your MAP when you install a HHO Generator.
