OK guys, I just spent an hour looking through this thread for the real story. Obviously I can find anything I want on the internet and believe it or not. Ecomike, you've followed this thing for many months.
Bottom line: Did Irainman ever post credible reports on mileage gains or not?
I don't recall for sure, I think he posted some early stuff, but no long term data. Goodburbon did post a complete test thread of his own in the Mod section. He called it Goodburbons HHO test or something like that. He was our Red River Chapter president last year, and an avid skeptic. While his tests were not extensive, he had one dual full tanks long round trip drive that was encouraging, but he had several maintenance problems that confirmed my concerns about several of the hardware design issues and the how to build a good enough design so it works consistently, and there is still the maintenance issue.
I ran across a guy in my Nissan diesel forum about 6 weeks ago with a custom SD22 diesel engine transplate in his jeep diesel like mine that added a turbo charger (the SD22 diesel is naturally aspirated), an HHO generator, and enough other stuff that he was able to regulate the HHO output in response to throttle position and vacuum (or boost pressure) and maintain a constant 2% HHO gas feed rate (which is part of the key to getting real good results) and he used graphite plates like I had suggested here. He went from about 34 MPG (the same as I get with my diesel) to about 50 mpg. About 1/2 of that increase was from the HHO generator (no boost), the other 1/2 from the turbo charger.
It is real hard for people to BS me on this sort of stuff, and he was only the second person I ran across where every single thing he said made sense, and was believable. The other was the 1978 DOE study that started all this HHO stuff during the last oil crisis.
In my opinion an HHO generator would need to be built from CPVC or polypropylene, welded and sealed with Viton o'rings, like in a high pressure liquid filter housing. The electrical contacts need to be outside the gas / liquid area, creating a design contact sealing problem, or else be titanium inside the cell and through the wall of the vessel, with compression Viton o'ring seals. Then the graphite plates need about a 1/16" or less liquid gap.
Need to run about 6-8 cells in parallel at about 1.8 to 2 volts per cell to maximize efficiency, and need a remote DI water feed tank to maintain a constant water level in the cells. Liquid level control then becomes a control issue too. The Diesel guy created a way to do it with his. Then you need the Pulse width modulator electronic DC pulse circuit board to get max electrical efficiency out of the system. They are made in China, and on Ebay for $75 apx. I bought mine direct from China for about $35, I am using it on my AC condenser fan to drop the fan current load, another project, story.
Then you still need the TPS control interface to the PWM (Pulse width modulation) board. He came up with his own.
There is a firm in Canada rigging something like this up on 18 wheelers, they are on the Canadian stock exchange, and have sold 1000s of them to the truckers up north for about $10,000 each, from what I read. And the truckers were reporting about 6 month returns on the investment.
In summary, the problem is the pickle jar version just does not really cut it. Right now gas is too cheap again for me to build one. Got other rates to kill this week, but It is still and idea I am following closely and will try on my rigs one day.
It would be interesting to hear updates from people like Irainman????
He may have gotten side tracked like the rest of us with recent disaster like floods, Hurricane Ike, stock market crash, job loss, who knows, .....etc.
I am glad to hear some of you taking it seriously now and realizing that while there are a bunch of crooks out there milking people with HHO junk, that the actual science behind the idea does have merit. One of these days a simple, cheap 2% Hydrogen or HHO feed set up may become standard on gasoline and diesel rigs, if we are still using gas then.
