Water Sparkplug

[nvisser]

Maybe it does not burns with supersonic speed, but it can blow a air cleaner into pieces on a generator. It also blow most of the bubblers water back into the cell. I can just imagine what could happened if it was a small bubbler.

oscillator

Hi Jet,,

That oscillator looks like the 4-transistor one I settled on with my Vexus circuit. I used 3055's and 2955's. Isn't this a great, simple oscillator? It's fairly low power as seen in my video on the subject and can definitely charge up a fair size storage Cap.

Ok, I understand now.
If your high voltage output from the ignition coil of positive or negative polarity? I would lose the inductor and put the diode string on the positive line and the other way around Did you use this on a running car or on a bench setup?

Here is what I am using and what has worked well so far:


But this is used only if the HV output is of positive polarity.
Hope this helps.

hi all. yesterday i bought some parts for oscillator circuit. my transformer only have 4 poles. 2 at input side and 2 at output side. how to connect this type of transformer since the schematics shows 5 poles. help help

The word is "Center Tap"

Center Tapped Transformer. If you don't have that you can't connect it up like the schematic. Allied Electronics, Digikey, or even Ebay can get you something.

thanks.. what can i do with this one. or just throw it away and buy new one?

[topangler81]

hi xack. did you install this plasma circuit to your car? did you experience power increase?

4 transistor oscillator for center tapped

So you both like that one? I tried a variation of that beacuse when looking
at Gray's old possible influence from tube radio days, they had the
choppers kind of like that. I was very disappointed with the results I
got from it. Then again, the circuit I was using had 4 npn's. I might have
to try this variation, probably much better if it worked for you all.

Hi Greg,
It's been a long time. My memory has faded but I thought your charge pump was based on a "H" bridge configuration. I can't find it in my folder, I'm sure I had it somewhere. Anyway, I would be grateful if you could post it again. I hope your keeping well.

Yeah Greg, that is the same circuit, it is so simple and works really well and you can easily adjust the frequency and other things with it. It can also be made very small so that the whole thing including the transformer is just a little bigger than the transistor itself

centre tap transformer

i dont have center tap transformer.....

[Jetijs]

Maybe you have yes, access to a computer junk yard? If yes, get an UPS and take the transformer from it. They are usually center taped. If not, you will need a different circuit that can switch polarities, or just simply pulse it with DC pulses, will also work, but I am not sure how well. Unfortunately I don't know about circuits that can switch the polarity.

[topangler81]

555 pulsed circuit.

Thanks. I think that 555 dc pulse circuit will suite this. Ill try. Is it ok to have only positive pulse? I think i can use 4pole transformer if i only have positive pulse. Thank

Hi Lee,

Fist off after frying many low-end inverters I went to a simple oscillator. Originally I use a 2-transistor self-oscillator that drew way too much current and then someone PM'd me the one both Jet and I use(d)(ing).

Here's my pertinent stuff:

http://home.pacbell.net/gmeast/vexus/vexus1.jpg
http://home.pacbell.net/gmeast/vexus/PF24series.pdf

I think that's all still left on line. vexus1.jpg is the same as better_inv.jpg but mounted on the phenolic board and with some chassis fans to keep things cooler (weren't really needed). The PDF is the spec. sheet for the transformer I used.

BTW - Does anyone know what's happened to Bill Cozzolino (the nexus guy, VW Bus, Mot, Skyhero, etc.)

Hi. Gmeast. You are the most experience in this. No doubt about it. Is center tap transformer is a must in this oscillator circuit? What mpg u get now?

Hi Greg,
Thank you very much. I may make a return to the water spark plug circuit.
Kindest Regards Lee...
