Lighty I can do this discharge constantly at higher frequency. It is STONE COLD.

It is not what you think.

I can also have the HV diodes coming off of the + of the BRIDGE when the bridge is disconnected from the cap AND with the inverter turned off....and it gives me the same effect...so there is no high temp high current arc across the gap.

See below:

Aaron and/or Others,

What changes need to be done to this circuit and/or others here so that we can use them as a plasma ignition system in car? Thanks.

The cold running scenario sounds very interesting. I want it.

Nice Circuit

Hi.
I wanted to make fuel ecconomy tests on my gas generator to see how much fuel I can save by attaching the vexus circuit to it. The problem is that I can not get the engine to run when the variac is turned ON. My gas generator currently has the original magneto ignition on default timings, so no primary winding in the ignition coil. It outputs a negative HV pulse. I attached the vexus circuit to it using a string of 18 1N5408 diodes. At first I powered the generator on and let it run for a while. Then I turned on the variac at zero volts. Everything worked the same, but as soon as I increase the voltage of the variac to about 40-50v, the generator starts to slow down and choke till it stops. The diode arrangement is correct, because if I wire it the other way around, I can not even start the generator - there is no spark at all. Might it be that the LV side is discharging through the secondary winding of the ignition coil when it is not firing and thus disturb the original spark form appearing?

This is how the setup looks like:

That's a nice looking circuit Jetijs.

Pretty Cool

That's great Mike
I just tried my generator setup using a voltage doubler for my 230VAC input. That is about 650V on the output. Works fine. I used a 75w light bulb as a resistor. At first I made a test with no vexus circuit attached, no booster side, just an ordinary spark. I made the test for longer time to get more accurate results. The ordinary spark circuit did consume all the fuel in 45m40S. Then I attached the vexus circuit with a voltage doubler. I also attached a microwave diode connecting the ignition coils LV positive to the HV output. And I attached a diode string in series with the ignition coil secondary to prevent the booster cap discharge through the secondary in between the pulses. This is the circuit that I used:



Now using the same load and timings, it took 49m14s till the same amount of fuel was consumed. That is about the same percentage (7%-7.5%) of fuel economy as without using the voltage doubler (just about 300V on the booster side). So there you have it. Now we need to think of a way to get water along with the fuel in the engine to see how this performs.
Thanks,
Jetijs

Pretty Cool Jetijs!!

Wow, Pretty Incredible

Hi all
I finally finished my timing setup. Here is a picture:



This setup allows me to adjust the timing up to 60 degree before and after TDC. It uses a small optoswitch that is glued to a aluminum piece that can slide around the perimeter using a deepening in the aluminum plate. Will test it soon.
Thanks,
Jetijs

You are a master that's for sure.

Thanks

Do like this:


If you put the diodes like in the upper part of the picture and there is no spark, then your HV is of negative polarity, if there is a spark, then your HV is of positive polarity

Thanks Jetijs!!

[Slovenia]

Thanks

Thanks Chris
I got it to work and it works even better on gasoline - more fog than with water. All you need to do is to connect the sensor metal plate with the fogger case with a wire and it will work in gasoline

Thanks Jetijs for this information. I would have been afraid to try this with gasoline.

Thanks

Guys, this was sent to me, he wants to remain Anon


I hold the keys to plasma what I am about to tell you can be shared openly the secret to making a plasma discharge in a vessel such as glass stable is to use iodine crystals. Iodine can also be used to change the colors in certain gas mixtures like xenon and krypton. Bromine will turn a krypton discharge from green to yellow green as well as many other colors can be changed. Flourine is also a very essential halogen for experimentation and can be mixed with multiple gas mixtures however iodine is the secret to making a stable plasma discharge of museum grade. helium makes a wonderful discharge but will seep through even the thickest glass over time. This gas is especially fun to work with krypton and xenon as well as argon react well with helium. A dash of xenon is included in almost every plasma discharge. Argon is used for bombardment the cleaning of the glass over a three hour period and when vacuumed out it remains in all fill mixtures in trace amounts. Argon makes a nasty red color but when mixed with neon it can make a nice display here too the power supply makes all the diffrence in the world with plasma discharge.

Thanks for sharing this.

Hi Top,

From your early post:

very simple oscillator circuit. at the circuit can i use an old 12v to 240 transformer? i think want to use it in reverse so it can produce 240v. and also ignition coil produce an high voltage, is 15 of 1N5408 enough to block the high voltage?
you using 15 diodes per spark plug of just one string to all 4 spark plug. sorry lots of questions i ask. just to make sure.

Something just occurred to me. If your transformer is over about 10 :1 ratio
like a 240v to 12v step down (turned around), it will not work with this simple circuit (or works poorly). I tried this many times.

Step downs like 120v to 12v and 240v to 24v (turned around) work well. I used a cap/diode voltage doubler to take me the rest of the way.

Slovenia,

This particular schematic was only a bench test to show that when the
variac was turned off from the wall power that the effect still happened
showing that it wasn't wall power making the effect.

I'd use the schematic Greg used on his VW engine.

ok. I understand now. My circuit now oscillating but very low frequency. I changed the cap to smaller 0.47uF. May be i have a broken transistor in my first test. Im using MJ15032 as my pnp. May be i need to changed it to mj2955 or something that suitable. . Ill post picture later.

using off the shelf CDI?

Has anyone used an off the shelf CDI and simply add a diode from coil
primary to high voltage? It would be the same as the single cap plasma
circuit and should work fine. Most would have about a 4uf cap at 400v.
That is the most common I've seen - at least in that range.

I have a few CDI's but haven't tried that yet but if it works the same,
would be the easiest for anyone to do without having to build a circuit.

A booster cap system could be added at anytime later in parallel with the
plug.

Circuit Pic Query

I have my Board all wired up and installed. Should I do a video of it running???



Cutting the hole for the plug was a real PIA! Next time I am just going to drill a hole and use a rubber grommet.

Hi Shane,

Do you have any other pics of your circuit you could share?
Also, what results are you seeing with this circuit on your engine?

Thanks for sharing with us.

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.

Thanks for sharing the circuit with all of us Jetijs.

water spark

Hi guys when using this circuit one has to make other modifications to the engine like a ceramic treatment and changing exhaust pipe to stainless steel?
Thanks
