I have been doing lots of research on the web and have most of the info from Stan Meyers 20 year research. He found by oscillating the current at a frequency of around 20 kh and I think also increasing the volts he made a lot more gas with less than half a volt, so no issue with the water getting too hot.

I have a friend who is an electronics engineer who is making something up for us to try.

I have been making units to test and lots of ways to do it wrong I found, but getting there. garthr your one way valve idea is another step in the right direction. The main prob is we are testing on a 5 litre engine, yes the enemy a Commodore. I am only on this forum as it has links when doing hho gas searches and the Commy boys don't so... Anyway I am near to the point of buying one of these kits as after about a month of heavy research they seem to have the best most professional set up. Above all though they claim to make up to 4 litres a minute which is way more than any others professional or backyard. One unit will handle up to a 7 litre motor. They also incorporate reserve tanks and filters etc USA company www.fuelfromh2o.com but have an outlet in South Australia www.fuelfromh2o.com.au

If u do buy one of those kits please let us know how it goes. They do look like a very impressive setup, and that sort of output is also impressive.
(Price is better than their previous system too)

As far as pulsing system goes from what i understand it works provided u pulse at the resonant frequency of the cell.(or an harmonic of that frequency?) And that is where it gets tricky since the pulse apparently does nothing until u get within something like 10 hz either side of resonance.
Problems too with the fact that resonant frequency of cell is variable with things like fluctuations in water level, temp, electrolyte strength etc.


Not that i have tried any of this, it is just some facts that i have seen mentioned.

keep up your experiments, & keep us posted,

Garth

We are making it with a trim pot for adjustment, will see how it goes.

Hello Garth, love the video, I'd do it myself if I new how!
Quick question, if there is one thing I find hard to get hold of, its the elbow fittings, if I may ask, where did find the ones that hold your level tube?
Update on my effort- Single glass/wire unit, re-wired with quarter inch spacings draws 3 amps at 13.2 volts. The EFIE I have fitted is set at 400millivolts (350 is neutral/standard) so its making some difference.
I have now 4 units made which I was going to fit behind the grille. I have measured it up and fitted holders, only to find the crash sensor in the way so only 3 can now be fitted,I may retain the 4th where it is. Hopefully this will be finished this weekend. I will post details once I have a chance to run it for a few days.
I have a further idea of making these units a hybrid, something with a plate set-up like yours but fitted though the cap in the W4G way.This way I could get 2 cells in the 3 units to give me 6 cells?
I better see how the 3 wire units go first!
Rob.

Rob,

I got those fittings from Tony Powell Hose supplies. (they are on Beaudesert rd at Coopers Plains. On the southbound side just past Granard rd)
Haven't seen anyone else that stocks them either.

as for the video - i don't know that much about it either but marcus did most of the tricky stuff with it.

Garth

Update on my setup,
Yesterday i fitted an extra cell to the hilux, bigger & better than the first one. Had to back off the electrolyte strength on both to keep max amps down a bit. So i am running at about 11 amps cold and 17 when hot. putting out just over 500 ml per minute.
just have to wait to see some numbers at the bowser now.

Garth, with that amount of amps, should it not produce more than 500ml of HHO? I would have thought it would have been more like 2 liters?
Rob.

measurung system mentioned in earlier posts was bottle under water don't know the accuracy cause gas would be compressed.

Garth, Have you tried the Cardy enhancer yet with your current system??

Update:
Here are the three units fitted behind the grille on my EL. As you ca see, they sit in holders all fitted together securely. There was going to be four units but forgot about the crash sensor which cannot be moved.
Have put them through a 15amp fused relay(seen on the left).
Current draw is fairly stable between 7 & 8 amps, from cold to hot at 13.8 volts with them connected in parallel.
With them connected in series, about 4.8 volts each, the current draw is only about 3.5 amps. They are not producing much in this way and suspect I would have to use a much stonger electolyte to produce anywhere near the same amount as they do connected in parallel. I will test them this way for the next week or two first.
They only get slightley warm where they are as opposed to when I had just the single unit fitted next to the master cylinder which got far too hot.
I have not re-adjusted the EFIE which is still set at 400 millivolts.
Hope this is some help to all you E series owners out there.

Hi Robert,

Very impressive setup, - neat & professional looking. Good job!

Maybe u don't need to run them in series if they are not getting too hot in parallel.

garth

Yes i would have thought so too, - but i'm hoping it will improve with time as the plates become more conditioned. also i will have to double check all the connections to my measuring setup - maybe not accurate.

BTW we put another bit of video together this weekend to show how this cell is put together here is link -

Here's something a bit weird, - i have noticed that whenever i do any highway driving (100 - 110kmh ) the numbers drop off to something like hwy mileage used to be.
which means that at the moment even in stop/start city driving i am getting better mileage than on highway.
So main advantage seems to be at or below about 70kph.

My theory is that maybe i still don't have enough hho for faster speeds.

Possibly need different tuning for hwy? (have seen that mentioned on the efie sites)

Any ideas?

*COUGH* Garth, Have you tried the Cardy Enhancer yet with your current system?? *COUGH*

then try one of these

Have fun.

Hi Garth, you may be right in that there will be a less percentage of HHO going into the engine with the throttle open more at cruise speed, than when your driving on light throttle around town. It stands to reason that there will be a lot more air going throught the engine at speed to ''water down'' the HHO content which will be a static amount?
Anyhow, where to you have the delivery pipe/s connected to? -manifold? before the carb? both?
My understanding of the HHO systems is that it requires both, as the manifold vacumn decreases when the throttle is opened which then becomes the main feed as the vacumn through the carb/throttle housing increases? and they require one-way valves so the vacumn does not suck back through the one with the least vacumn.
Rob.
