Hydrogen generator installation

[mojoplayer]

Has anyone installed a Hydrogen generator on an 07 Tundra 5.7L? Any advice/instructions/photos would be greatly appreciated.

What do you do with a Hydrogen generator in the Tundra?

Mix with the fuel vapor to increase gas mileage.

So, more like a Hydrogen injection setup? I've never heard of that before.

probably more snake-oil... Adding H2 to the fuel stream will probably use up the oxygen in the mix and effectively make your engine run rich.

I have seen some outrageous claims for those "customers" using some of these systems.

p.s. it makes the engine run lean, not rich. I doubt the claims personally, the one company that does seem legit sells kits starting at $7,000 and claims 10% fuel savings. Sorry, but I can buy a Hybrid, and see more fuel savings for less money.

^^^$7000 for 10 percent fuel savings? Economically spending the $7000 on gas makes more sense, it would take forever to break even on that investment.

First, I'm not buying a system, I'm building one. You can purchase everything needed from a good hardware store and an autoparts store for well under $100.
According to the many blogs and articles I've read on this subject, the engine will not run lean or rich because the fuel control computer will automatially adjust the the fuel flow to the correct mixture. I'm trying to find someone who has installed a similar system on a Tundra to se where they tied the generator into the system.
The other experimentors that have used these generators hav reported fuel efficiency increases of 25% to 75%. It may be "snake oil", but for less than the cost of two fillups, I'm willing to give it a try.

Sorry about this but my personality necessitates getting the science right.

I'm no mechanic, but my understanding is that a lean condition is where the ratio of Oxidizer(Oxygen form Air in an engine) to Reducer(Gasoline) is higher than required for the optimum burn. Since gaseous Hydrogen is not an Oxidizer the Air/Fuel ratio leans towards the fuel side since there has been no extra oxidizing agent add as well.

Isn't H2 a combustible gas? That's what was in the Hindenburg, right? I really have no idea, Chemistry was a while ago for me (okay, only like 3 years, but I've already forgotten).

The gas produced by the generator is 2 parts hydrogen and 1 part oxygen. I have not installed the generator yet, but the reports I'm getting from others that have is that the computer takes care of it, and sends less gas to the injectors resulting in the fuel savings. I saw a film on youtube in an old F250 that resulted in a 72% fuel savings, but typical in late model vehicles is 25% to 40%.

Yes, the theory is the computer (with its control over timing) will not allow it to be too rich or too lean. But if the timing changes, then power will go down or up. Odds are power will go down. And seeing how no one with a Tundra has done this, there's no way to know if the ECU will work right.

And yes the H2 is highly combustible, but that's why there isn't an on-board tank in the vehicle. Again the "theory" is fantastic for this thing.....you generate the H2 needed as you drive. But my reading indicates that you probably can't generate enough H2 to really do anything anyway.

mojo, I hope you are able to do this......and hopefully you can share what your results were.

So you're making water?

[CrashTestMike]

It does take quite a bit of power to break the Hydrogen-Oxygen bond in water. This energy has to come from somewhere. In the case of a vehicle it's you gas tank....

The operational theory here falls in line with perpetual motion

[mojoplayer]

Well...not quite perpetual motion. There are guys out there trying for that, this is basic chemistry. My experimental cell was pumping out quite a lot of gas at 12vdc and .5 amps! I burned this baby for an hour straight with no increase in current, and only a slight increase in temp (I stuck my finger in the cell after an hour and it wasn't even warm). The alternator in the Tundra is oversized (like everything else) so even if it drew 10 amps, it wouldn't be a problem. I will keep you guys posted, but I need your help. Anyone that has an advanced knowledge of the Tundra fuel system could be very helpful to me in figuring out how to set this up in the vehicle. Thanks in advance for your help.
