Hydrogen Injection - Hydrolysis
Hydrogen injection,or HHO Injection, is a modification whereby electricity produced by the vehicles charging system is used to split water through the hydrolysis process. The resulting gas produced, a mixture of atomic hydrogen and oxygen, is released to the intake stream of the internal combustion engine, and it increases the efficiency of the engine.
It is important to understand that this is not an 'energy for nothing' gadget. Any energy conversion process is not 100% efficient. The amount of energy required to split water molecules to hydrogen and oxygen is greater than the energy reclaimed in recombining them. The efficiency boost from a hydrolysis system is not from the energy when oxygen and hydrogen recombine in the combustion chamber.
That hydrolysis systems work at increasing efficiency and gas mileage in internal combustion engines has been shown time and time again. We've seen it in our own work with these systems on both gasoline and diesel engines. What's more, several US government agencies have investigated this effect and their reports indicate that they have found the same effect.
In our own investigations, we have seen fuel mileage increases from 20% to 30%.
Hydrogen injection works by increasing the efficiency of the combustion of hydrocarbons. It is a complex process best understood by engineers, and involves the flame front under compression in an internal combustion engine. You can find much information and details about how hydrogen injection improves efficiency in an internal combustion engine here.
On modern fuel injected engines, there are sensors in the exhaust stream (O2 sensors) which adjust the combustion mixture so that there is some wasted fuel (unburned hydrocarbons) in the exhaust. This is so that the engine doesn't run too lean and hot. Automobile manufacturers are using fuel to cool the engine during running. At $4 per gallon, that's an expensive practice.
Since hydrogen injection causes a more complete burn of the fuel, it will affect the readings of the sensors in the exhaust stream, and the onboard electronic fuel injection system (computer) will attempt to compensate for this. In order to get the best possible efficiency from a vehicle with hydrogen injection, it is necessary to compensate the readings from the exhaust stream sensors (lie to the computer). Fortunately devices that compensate for the exhaust changes are available. We've used and highly recommend the product found here.
There are some concerns with hydrogen injection. Hydrogen is reactive. Hydrolysis is producing a mixture of hydrogen and oxygen, sometimes called hydroxy gas or browns gas. It is explosive. During hydrolysis in vehicles, small quantities of this explosive gas is being produced. It is being produced on demand, and not being stored. What's more, inline safety devices such as check valves prevent ignition from backfire.
Hydrolysis requires an electrolyte, which is dissolved ions that carry an electric charge through an aqueous (water) solution. Baking soda can be used as an electrolyte, and is perfectly safe. We've found that caustic solutions are much more efficient as electrolytes, and produce much more HHO. The presence of caustic solutions means that care must be taken when working around these systems.
And finally there is the maintenance aspect. Water must be replenished in the system as it is consumed by hydrolysis. We've found that our systems need about one liter of water replenishment per tank of fuel. Adding water shouldn't be a big deal, but it is an added step at filling time. The water reservoir is usually kept under the hood. In winter it is sometimes necessary to add an electrolyte to the water reservoir to keep the reserve tank from freezing.
We have two hydrolysis units available, along with an installation kit that includes all the fittings and incidentals needed to do a proper hydrogen injection installation. If you have a newer, fuel injected vehicle (and who doesn't) you'll also want to click the link below and order an IFFIE to compensate for your increased combustion efficiency.
