too much water vapor
problems
I have built the gas4free system and installed it on my 2007 GMC duramax turbo diesel, I have two problems.
1) too much water vapor going through the tube, water is getting into my air intake.
2) I'm not getting any increased mpg, none.

The system is bubbling like crazy and producing HHO, but I'm not getting any benefit from it yet.

Please help.

looking 4 more mpg!

Sounds like you've got a heat problem; you're producing steam, not HHO. Give us some more data, e.g. LPM cold; LPM hot; electrolyte; how many plates; etc. It's going to take 5 or 6 LPM HHO [not water vapor] to see some results. Do you have O2 sensors?

Heat caused from a poor cell design. You need to get closer to 2 volts for each set of plates. If you have several "jars", you could wire them in series to make them run cooler.

I agree with Thomas, you probably need a lot more output.

I talked to Bob Boyce about this very subject, while I was at the HHO games in January.

He says that you need 1/4-1/2 liter/min per liter of engine displacement. Therefore a 4 liter engine needs 1 to 2 liters/min. Now realize he's talking about pure HHO. His systems run at 90 degrees, and produce no steam at all. So with the steam, all bets are off because you don't know how much HHO you have.

RE: too much water vapor
I'm using 6 negative plates and 5 positive plates, just like it said to do in the plans. The water/ 1tbls peroxide mix does get very hot.
I'm using 12 gauge wire and 30 amp fuse to power the unit.
how can I reduce the heat?
How do I test for LPM?
I have a 6.6 liter engine. Is this gas4free system even capable of producing enough HHO to make a difference?
Thanks for your advice, it's REALLY appreciated.

Mike

RE: too much water vapor
Mike, was Bob's LPM figure for diesel engines or gasoline? Diesel's run a lot more air thru the engine, which IMO means you'd need more hho.

colchiro,
I'm assuming his figures are for a diesel engine since that's what I said I had, to be sure, you'd have to ask him.

I thought I was. Wink

Sorry, I didn't realize we had more than one Mike.

I deleted your other post which was similar to this one.

He didn't specify, actually. I took it to mean both. But the real point is, that he was recommending a much smaller amount of HHO as the recommended correct amount than I had thought.

My bad. I hijacked your thread a little bit there.

But per those recommendations you only need 1.5 - 3.0 liters/min. I would think you'll do fine with 2.0 liters/min. To find out if you're getting that out of your electrolyzer, you can use a 2 liter soda bottle in a bucket of water, and run the output of your electrolyzer into it. Time how long it takes to displace all the water from the soda bottle.

But note, if you're electrolyzer is running hot, you'll need to make adjustments to get it running cool. Otherwise you'll only be measuring steam. Good electrolyzers can run at a temperature where you can easily make contact with your hand without the surfaces being too hot. Then you'll know that the gas coming out is HHO and not steam.

Thanks Mike. I trust Bob's judgement.
