Water Sparkplug

[Slovenia]

Thanks

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.

Aaron,

Thanks for clarifying this and for your recomendation.

Best Regards,

Hi Top,

From your early post:




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.

Greg

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.

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.

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.

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.

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

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!!

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.

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!!

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.

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.

lean burn

Hi Greg,

I looked at other Popular Science issues online during that time and it seems
that Smokey had a regular column where people can write in with questions
and he answered it. Like a Dear Abby for car topics.----------------------
-----------------------------------------------------------------------
One of their primary purposes was to burn lean mixtures and according to
the SAE abstracts and other resources, it worked better than any other
ignition. Better than CDI, better than peaking caps, etc...

Hi Aaron,

It sure Worked. When I used the next-to-the-smallest fuel jet for my carb./engine combination in the Bug, it would hardly run without my Vexus circuit, and as expected, I did get a rise in temperature (even in that cold-blooded beast) hence my use of lots of steam vapor toward the end. One thing allot of people can't detect is the smell of super-clean combustion (if there's such a thing)... if you've ever been around high performance race cars or aircraft you will know the smell I'm talking about. That's what the Bug's exhaust smelled like ... clean and efficient.

This method of the "water sparkplug ignition" has an official name in the
industry and it is Plasma Jet Ignition or PJI. And their modified plugs for
using this ignition are simply Plasma Igniters.

I found a lot of different ignition system patents with this concept, but
if you search for PJI or Plasma Jet Ignition, you will find even MORE!

not working???

Hi all. My oscillator circuit still not working. Make me wondering why this simple circuit become so hard for me. Not lucky i guess.

Hi Top,

It is a simple circuit. There are a couple of possibilities. One possibility is you have one (some) bad transistors. What PNP's are you using?

I will stress how much easier it is if you have a scope (infinitely easier).

Are you sure you are using the right transistors in the right place?

Again, are you sure you have the transistors hooked up correctly?

Can you take a good picture(s) and post them?
