I am new to the hydrogen world and need some advice. I built a 9 plate generator (Hydrogen Garage Design) and installed it on a 1997 Nissan Sentra. I am using tap water with lye as electrolyte. I made no other changes to the car when I installed the generator. Experimented with more and less lye to increase and decrease amp draw. I drive 50 miles one way to work, mostly highway miles. Without hydrogen I get 36 mpg. With hydrogen and 10 - 15 amps I got 37.7 mpg. At 15 - 25 amps I got 35mpg, obviously too high of amp draw. I expected 25% to 40% better mileage. Is the oxygen sensor causing me problems? Any advice is appreciated!
Yes. The O2 sensor will read that there is too much oxygen in the exhaust stream and the cpu will attempt to compensate by making the fuel mixture rich. You need an EFIE to tune or "trick" the O2 sensor. The O2 sensor will be in an open loop when cold (under 600 degrees)and a default mixture will be entered. That is why you get some mileage when cold. There are many places to get an EFIE online, just do a search, they cost around $70.
Also you need to use distilled water, to many elements that effect production and make gunk in your generator, with tap water. distilled makes it easier to control your electrlyte solution to your desired levels.
I do not know what the pin out is on your MAF. If you buy a haynes or chilton book for you year and make of car it will have a schmatic that will show the electrical equivalent device. normally a potentiometer. I have some training and knowledge of electrical and electronics and took it upon myself to modify the MAF voltage output reference level using a resistor across two of the three leads of the MAF connector. This made the MAF not see as much of the air flowing passed it. At that point my booster had a dramatic effect in lowering my gas consumption. Also my car ran better. Quicker accelleration. See what was done at web.hometel.com/~tron
Nov 1, 2008 I found that if the resistance value is too low the car cannot accellerate past a certain point. Also it is said that if you make the fuel to be too lean you might burn a valve. Too much air vs gasoline will make for a higher burn temperature.
i am new to this web site. i have several questions. any help is greatly appreciated. i'm trying to build a generator to supply a large diesel engine (14+ liters). i've read that i need approx 170-200 LPH. what size plates & how many do i need? should i go with pos neg pos etc.? or should it be pos neutral neg pos neutral neg. etc etc.? i'm trying to keep the amps at around 20. is there a formula to convert LPM or LPH to CFM? also is there a commerically available flow meter, and from whom.

New item. Some people found that they could get their control modules to adjust to accept the booster better by disconnecting the battery for a minute or two. Not only does this reset a code it also causes the module to review all the inputs to it and adjust accordingly. Not in every instance, but on some cars. Also take note of where you choose to input the hydrogen.
