HHO

Hello kleef

Yes, the possibility of a damaged engine, a lighter wallet, the risk of explosion with associated messy death.

Keep well clear of such, please.

Kind Regards....

Thanks...lives and engines may be saved.

Hi Kleef, a friendly word of advice here. There's no such thing as HHO. Even water is actually HOH, strictly speaking. Brown's gas is nothing more than a mixture of 2 parts hydrogen to one part oxygen by volume. Don't be taken in by the scammers who claim that electrolysis can convert water to HHO for burning.

HHO is not meant to be a chemical description of a molecule but a shorthand for the mixture of two Hydrogen molecules for every Oxygen molecule produced by electrolysing water. Brown's gas is indeed the other name but no one remembers who Brown was and HHO has become the common term for this explosive mixture.

Have you ever even attempted to do this? I have personally produced a combustable gas using the techniques provided. It does produce a hydrogen gas which is very combustable, regardless of the way you "arrange" the chemical equation.

Yes, I've electrolysed water to produce hydrogen and oxygen. It is indeed a highly combustible mixture of gasses. Overcharging lead–acid batteries do this in everyday situations.

I am not sure what you mean by 'regardless of the way you "arrange" the chemical equation'. In oversimplified terms the reaction is: 2H₂O ⇔ 2H₂ + O₂ What you choose to call the mixture of gasses is up to you. There are various terms used, some of which seem to provoke strong reactions from some members of this forum. Common terms are HHO, Hydroxy, and Brown's Gas. I am unaware of any different "arrangements" that might be signalled by these different terms; I take them all to mean the same, viz, 2H₂ + O₂

Yes, plenty of people have experimented with this. There seems to be a mixture of con-artists and genuine folk out there and some very poor understanding of what's involved and why it works. Check out YouTube for video clips of people's demonstrations and experiments. (Search for HHO, Hydroxy, or water car.)

Safety

Hydrogen is a dangerous gas, particularly when compressed and when mixed with Oxygen or air. Most of the systems out there use a "hydrogen-on-demand" system that doesn't store the hydrogen but pumps it straight into the engine or inlet manifold. This means that HHO systems are not dangerous (unlike having a tank of Hydrogen on board like the commercial units that some car manufacturers are making.)

Hydrogen explodes. So does gasoline [petrol] and diesel. That happens inside your engine; it's what it's designed for. The amount of extra explosive power involved in the addition of the HHO gas is minimal. Your engine is not going to explode. You would have to pump HHO into the cylinders at very high pressure before you got enough to exceed the strength of the engine.

How can it work?

Internal combustion engines are notoriously inefficient and much of that is to do with incomplete combustion within the engine cylinders. That is why we've taken to adding catalytic converters (CC); to burn of the fuel that runs out of the engine unburnt. Even if your CC isn't needing to kick in, the fuel is probably still burning as the exhaust vales open and expel the gasses into the exhaust. There's plenty of room for improvement here.

Adding Oxygen is good for any burning process (that's why we supercharge our engines with turbochargers). The extra energy from the relatively small amount of Hydrogen added by these systems is not going to increase the output very much. Hydrogen is, however, a very nice fuel as it burns quickly and smoothly. (This is in stark contrast to fossil fuels, which are slow and somewhat unpredictable.)

The way these systems work to improve the output of your engine is to improve the burn. Having a few Hydrogen molecules in the mix means that the explosion in the cylinder is faster, smoother, and more complete. This means that your CC is practically redundant and people have even reported carbon build-up "coke" in their engines being burnt off and noticeably cleaner exhaust fumes.

Misunderstandings

Many folk; even intelligent, thinking people are very dismissive of this emerging technology. Much of that is to do with the hype that some have given it and much is to do with the poor, unscientific explanations of how it works that are given by those wanting to sell something. There are plenty of folk who have posted stuff on websites and uploaded clips to YouTube but there is still those who insist that they need "evidence". What would convince them? My guess is that they are not willing to try such a conversion on their own car to see if it makes a difference.

WELL PUT....
