reece--google hydrogen generators forum - the generators that you dont want are the ones that have each plate electricaly charged. these overheat the water and the hoter the water gets the less effeceint it is-the generators that have multiple plates but only the outside ones are conected to a voltage sorce are the ones your lookin for. the inside plates not connected to the voltage source are still charged.....its kinda hard to explain really but the generators we need for our trucks need to push about 3-4 liters of HHO and do it without overheating while also drawing the least amount of amps. i would really advise against a glass jar generator-they sell that crap on ebay and its kinda scary.
on a diesel you dont have to alter fuel flow. to be honest with you, im not really sure you would gain much in a gas engine-thats why i think they sell those ecu foolers inorder to run the car leaner-thus getting slightly better fuel mileage. from my understanding-the hydrogen on a diesel works so well because any time you get black smoke in a diesel (acceleration ect...) the hydrogen helps burn that excess fuel in the chamber instead of the muffler.
and also when cruising down the road 600 ft lbs of torque (the motor is not exerting that much all the time but you get the point) turning the alternator for a couple extra amps to run a hydrogen generator is less parasitic then it would be to a toyota camry. to express my point...if you do alot of night driving you will see a greater fuel loss from the camry from headlights and radio then you will from a cummins. this maybe because the cummins has more available (spare) amps to offer then the camry....i dont know but i know their is more gained from hydrogen generators then what is lost to power the generator itself-and this to me is kinda weird cause the rules of thermaldynamics basically says ---you cant get more out then you put in.
the only reasons i can think of why it works are
1. we are, putting in that much! the HHO is just helping us use it (instead of black smoke)
or
2. the alternator in a diesel has enough spare amps layin around that sending 5 or so amps to a generator is no big deal.
or
3. both 1 and 2....the more effective combustion process makes up for the extra parasitic draw of the alternator thus the HHO injected after that point helps with extra fuel for better mpg
but either way i think about it, i just cant rationalize how it would be cost effective (or opperational) on a gasser
however you go about it--you will not see much gain(if any) if you use a generator that pulls alot of amps, overheats and doesnt give off much HHO---
it works! but only if you build a generator thats efficient
im still kinda messin with my generator but when i finally get it the way i want it and get it mounted ill show you guys the finished product with instructions so you can build it.(the build instructions on the internet are either pricy or worthless or both) but right now im still building this house so give me a month or two
