On a diesel engine, you can just inject the water straight in the intake and burn it. It will provide moderate HP gains at virtually no cost.

It would be a little rough on your antifreeze.

The concept would work but would be expesive and complicated, there are better solutions for recovering energy from waste heat coming down the line.

google thermoelectric alternator for a sample.

[Laserman]

However, if introducing H2 into the gas combustion process improves the gas/diesel combustion efficiency, it could possibly be a net gain in overall efficiency.

[Smokin' Joe]

HHO? H2O? Samey-same? It sounds like water injection to me

[Red Badger]

HHO is hydrogen gas and oxygen gas separated by electrolysis or some other means, but not combined until it’s “ignited”. Another term is “Brown’s Gas” and Oxyhydrogen..............

Smoke and mirrors until they separate H2O with less energy than they can get from combining it.

Perhaps Nancy Pelosi could write legislation repealing the first and second laws of thermodynamics?

[Paleo Conservative]

Hussain says users can expect “increased engine power, smoother gear changing and a cleaner, quieter, longer-lasting engine”.

You don't think someone named "Hussain" would lie do you?

[Red Badger]

Democrats don’t repeal laws, they write them!..........

[Red Badger]

This “Hussain” ain’t going “Barack to the Future”.............

[Paleo Conservative]

Are they introducing the HHO into the carb separately from the fuel?

They should be very careful. Just a little dihydrogen monoxide can kill.

But this is in addition to the gasoline already being combusted. The 2H2 and O2 will be consumed in the same ratio they are created. The chemical reaction of each fuel combustion are separate but simultaneous. There is not a claim of a new chemical reaction but Hydrogen burning with the gasoline.

[Cold Heart]

Physics hasn’t changed. Improved combustion means you get more BTUs out of the fuel you are using. The extra energy you obtain is coming from your main fuel burning more efficiently. The energy from the H2 in the combustion process is pretty much a very minor loss compared to the energy used to create the H2.

A good example of the heat loss from incomplete fuel combustion occurs at the catalytic converter. The heat created by the action of the converter would instead be obtained in the engine with the H2 added. Simple physics.

This scammer has been all over craiglist trying to get mechanics to train on his voodoo product.

[Chaguito]

I would invest right now, but all my capital is tied up in San Bromista, Mexico.

How does s whiff of hydrogen make the fuel burn more efficiently? It might add a bit of fuel like injecting any other fuel but that is not increased efficiency. The converter uses the excess fuel so what is really needed is more air or a leaner mix as in a stratified charge.
For $150 I can put a free breathing air cleaner on my truck and get proven increases in hp. and mileage. Add synthetic oil and better spark plugs would add still more. These things work and don't make silly claims of 40% increases in mileage.

[Cold Heart]

“How does a whiff of hydrogen make the fuel burn more efficiently?”

Adding H2 changes the combustion chemistry. It’s molecular thing.

Does using kinetic energy count? Once the alternator is running, wouldn’t that be enough to sustain the reaction?

No, and here is why.

It is impossible to sustain the reaction.

Every time you change one type of energy to another you will loose some due to inefficiencies.

Examples:
Alternator is rotational energy potential. Its losses occur through mechanical friction, air resistance, and electrical resistance in the wires, and kinetic energy through heat caused by the resistance in the wires.

Once you have the voltage (electrical potential), you want to break the bond in the water. So where does the chemical energy come from. As a matter of fact the water molecule is in a lower energy state than its components. By separating them you can then liberate this chemical potential thought combustion. However, there are still inherent losses of energy in the electrical resistance of the electrolysis circuit. These losses occur as kinetic energy losses (heat).

Now that you have the elements separated, you want to burn it. Once again, you loose energy through mechanical resistance in the engine, and the thermal energy loosed thought the exhaust, and absorbed by the engine block.

As you can see there are so many opportunities for energy loss in this system, that it is absolutely impossible to sustain it.

[count-your-change]

I think I understand what you’re saying.

[chaos_5]

Correct me if I’m wrong, but it seems there is a lot of “wasted” energy being generated by the alternator and exhaust heat.

Yes, there is a huge amount of energy lost in the exhaust. If that waste energy could recapture, then you would improve the efficacy of the system.

As fast as the alternator goes, it is much less than the amount of energy lost through heat.
