hi ,

i purchased this 21 plates HHO generator >> http://www.aliexpress.com/product-fm/334099761-21-Plates-316L-Supper-HHO-Dry-Cell-wholesalers.html

and for first time i have used a car battery to run the generator ... but nothing happend and it 's not working ... water went into the generator well and negative and positive terminals are OK ... i test it by a PWM too ... again nothing .

what u think?!

You did not mention anything about the kind of electrolyte you used?

i did not use anything for electrolyte .

should i use electrolyte always?!

No electrolyte? What are you using, tap water?

distilled water :D

OK, It's time you started doing some research. The water alone won't conduct electricity! That is why it needs to be mixed with NaOH or, preferably, KOH.
A 28% KOH solution works best as long as you can use a CCPWM to control the amp draw.

tnx , it 's working now.

Glad to hear it! What are you using for electrolyte and what percentage?

i tried the bicarbonate ...

i am not sure about percentage exactly .. but near to 100 grams

My approach differs from some. Some like 28% (full concentration for KOH) but you should only do that if you have a PWM.

I add electrolyte a little at a time, until i get the results i want, while the cell is cold. You will find that output and amp draw will increase with temperature so i use a PWM to regulate that. If you dont want to use a PWM, then adjust electrolyte ratio so you get desired amps at max high temp. 20 amps is a good starting point for testing results.

If you want to improve sodium Bicarbonate, spread it out on a cookie sheet & bake it at 300f for 1 hour, you'll then have sodium carbonate. it works better than bicarbonate. ;)

i am testing it on a 6.6 L v8 engine .. it 's getting around 30 amp now and hydrogen production is not bad ...

how can i know the engine using the hydrogen really?!

For your engine the HHO output will need to be at least 3.3LPM minimum (actual dry gas) to get any positive gains. Looking at the reactor you purchased, lots of the 'output' is going to be steam. A 21 plate system is probably -NNNN+NNNN-NNNN+NNNN-, which means that each cell is getting 2.76 volts. Way too high! Most of what it'll be producing will be steam, not HHO. At 30 amps, the current density is around 9.3 which will deteriorate the plates quickly & run hot. The density should never be above .50. Change it to a 19 plate system like this: -NNNNN+NNNNN-NNNNN+ and it will work much better.
You claim the production is 'not bad'. What exactly is the output?

3 lpm when engine working at idle .. when i push the gas pedal and RPM rise up around 2000 RPM ... it will be around 4 lpm ... because it 's getting 35~40 amp always

i have some PWM but because it limited to 30 amp .. i don't like to use it .. i know it need more than 35 amp to provide me more than 3.5lpm for this kind of engines.

Now, before you go any further, read the entire section in here called 'Best Electrolytes'. Only 60% or so of your gas output is doing anything at all and the side effects from using Sodium Bicarb can be damaging.

it seems the KOH is best about Electrolyte for now

how much of KOH is enough for 2 liters of water?!
