HHO in internal combustion engines
Less fuel, more kilometres per litre, less emissions
An important application of HHO-Watergas is to reduce fuel consumption in internal combustion engines. Not only fuel consumption decreases, but also emissions of CO2 and NOx is reduced drastically. You can find a lot of information on the internet. Here we provide you with some keys to the lake of information.
On seperate web pages you find HHO-companies that offer watergas units in the market. When your company is not yet included, please mail us for the conditions. The more HHO-companies with a good track record can be found, the better the market will develop. Now in Europe the market is still very young. The HHO-sector has to prove that Watergas works under which circumstances.
A good introduction to HHO-Watergas for Ineternal Combustion Engines you can find under this HHO-link.
Developers already active with HHO will appreciate the work of Charles Ware entitled "Optimized HHO injection for Class 8 Diesel Vehicles".
We give more links on this subject through the Web Links section.
This is what is often found on the internet. But the nay-sayers do not tell of the conditions in which they have tested. And some critics even air bold opinions without being prepared to proof the pudding by eating. But...where you see smoke, often you can find fire.... Indeed in some conditions HHO does not work as expected - in particular in modern cars with advanced motor management. When does it not work?
a) Materials of the HHO-cells are not appropriate
A special alloy of stainless steel should be used (e.g. 360L), while the plates of the electrolyzor need be treated well; sometimes producers make HHO-celss with inferior materials that are not up to the hard conditions under the hood of a car. Ask for guarantee and leave installation to a trusted garage or service centre.
b) Some electrolysors become hot during production
Instead of HHO the cells might produce Hydrogen and oxigen. Then the cells are heated up and some even get to boiling temperatures and even produce steam. Well constructed cells will reach temperatures of about 40 oC but not much more.
c) HHO is very thin gas. Gas leaks occur when plumbing is not well done
d) Motor management detects too much O2 in the exhaust
Fuel consumption may even rise 30%! So in modern cars you need a device that corrects the information that goes to the motor management. This can be done with e.g. a Volo chip. Setting of the chip is specific for each type of car and engine. Important is the information from the Labda sensor. This sensor reads the oxygen content in the exhaust gas. With HHO the O2-content increases. The motor management of the factory reacts with additional fuel. The input in MM can be corrected. It would be optimal if the Car Industry would adopt HHO-hybridization and provide their own HHO-correction chips.
e) Electromagnetic fields may destroy watergas
In some cases it seems that electromagnetic fields destroy the power of the watergas. Be aware! This is not yet scientifically proven, but we expect that this may be the case in some failures of HHO in engines.
f) Too much HHO
The amount of watergas is normally about 0,5 to 1 % of the volume of air intake. When more HHO is added, the effect may be blown away. HHO acts as a catalysor of combustion. At amounts of 5% and more the HHO starts to act as a fuel.
g) Dirty cells
Some cells need be cleaned periodically - for example when lower quality plate materials are applied the cells may produce kind of a deposit that eventually hinder HHO-production. Titanium coated plates reduce this fenomenon, but are more expensive.
Five years ago many producers were still rather ignorant. But the quality of the products has improved much. But we need consumer input. Please be welcome with your testimonials. We will forward them to the producers.
Proof and testimonials
On internet you can find many testimonials of HHO-consumers. However, scientific proof of principle is still scarse. So, we want to collect as much as possible documentation of scientific studies. Please, if you know of good reports and studies that can be published, please inform us with by mail. Thanks!
How HHO works
The working of HHO in an engine is primarily based on the very high propagation speed of the combustion of watergas.
When diesel fuel combusts, its flame propates with a velocity of about 1 meter per second. You can calculate that - especially in older diesel engines - the burning process is so slow that not all fule is burned before the piston is moving upward in its cycle. So remainders of unburnt fuel is left in edges and soot remains stick on the valves. Soot is like sanding paper, it is the main reason of tear of the engins inside.
Now we add HHO to the air - fuel mixture. The front of ignited HHO speeds through the combustion chamber. All and everywhere we have the intense heat of combusting HHO. The tiny diesel-fuel droplets are surrounded by this heat and start to combust as well. The study of Oldenburg University contains pictures of flame propagation in the combustion chamber with a mixture of fuel and HHO.
HHO acts as a catalisor. We don't need much HHO to be effective. HHO works best at a percentage of about 0,5 to 1 percent of the volume of air intake. It is is even observed that a too high percentage of HHO blows away the effect.
Effects of HHO addition
Addition of Watergas (HHO) into an internal combustion engine is threefold;
1. Less fuel consumption (CO2 goes down)
is burnt more efficiently, so the same amount of fuel produces more power.
2. NOx emission decreases
Combustion temperature is cooler - the pressure peak is higher but shorter. Less NOx is developed. NOx is basically burnt nitrogen from the air.
3. Reduction of soot
Almost all fuel is burnt. Soot reduction of 50 to 80% is reported. Reduction of soot results in cleaner engines. Engines get a longer life.
Car on HHO? Also on NH3!
Stanley Meyer has run a car on water.But in his patents he uses terminlogy that is not untrue, but hides what truely happens in the engine of hus Dune Buggy. Now some sources reveal that the inert gas Meyres mentions is in fact ammonia. HHO and N2 from the air is transformed into ammonia, which is a combustive gas.
