Water Sparkplug

[tstorey]

Thanks Mike!

This is a really useful finding as it something we can see and therefore measure.

This time at 125 psi..............

It's just me again,

I did it this time at 125 psi, 2,300 rpm. The higher the pressure, the bigger the plasma gets!!! Keep in mind, I am ONLY discharging 2.5uF in these vids! The reason, I think, that I had to make a new combustion chamber plate is because my painter was using his DRY air system at the time I wanted to make another video. I used regular shop air and it has moisture in it. The plasma built up size as I increased chamber pressure........And BANG! I'm betting the large plasma ball ignited the amount of water vapor coming through the air hose, the pressure had no where to go, so it blew out the see-through plate. It was quite a boom, I nearly wet my pants! It seems to me that using an ACTUAL combustion chamber is the only way to get an accurate test result. The shape of the head's combustion chamber is a series of angles and curves........it is that way for a reason! The link is below for the 125 psi test.

Great job Mike
What is the plate made of? Plexiglass, acrylic? If yes, then maybe you should switch to polycarbonate. Because it is more dense and flexible and wont shatter on big loads like plexiglass or acrylic does. This stuff is what the bullet proof glass is made of
Thanks.

Thats great, I cant wait to see it push a piston down (violently) . Lets see how much pressure it has.

I tried this many times but no results, this is a 30uF charged to 340V.

Maybe the engine design will have to change to take advantage of the plasma effect on the water.
So far the plasma really only has an effect on the water in the plasma area. So it seems you are only getting a small volume increase when the water "burns".

So maybe a small stroke/large bore engine with several plasma sparks in the head could produce a working engine.


Do we have a latest schematic that us "electronics laymen" can work from.

VexUs Plasma Vs. 125 psi

Great Job Mike !!

What is a normal compression ? For some reason I was thinking it was much less than 100 psi. Did you confirm that air + moisture produced a larger plasma than dry air ?
Just wondering if very dry air might contain more ions and if that would correlate to more plasma or less. Moisture would disipate the static, but may provide a molecule to ionize.
The compression test I was thinking of would be a cylinder such as a pipe, acrylic tube, etc, with the plug in one sealed end. The piston would be a solid steel rod (w/O ring). The idea would be for the rod to be ~2" cross sectional area and weigh 20 lbs. giving a compression of 10 psi. Pull up the rod and draw in a specific volume of gas, release to load to 10 psi, then fire the plug. Measure the rod displacement for quantifiable measurements.

I've built every Greg design so far, so I need to build his new circuit.

Keep up the great work.

New Video of VexUs re-installation

Hi guys,

The oscillator plus voltage multiplier seems successful. It's in the Bug and runs fine. The plasma spark is modest but still a plasma spark and explodes water easily.

I have gone to higher voltage and lower capacitance at the CDI Cap. The discharge is very, very fast and hard to capture the true intensity with the camera. Mike understands where I'm coming from on this issue.

The transformer warms up a little at prolonged higher RPM while driving around, but I can correct that by directing the flow from the chassis fan better.

I think I have proven that (at least my) inverters suffered control CMOS failure followed by self destruction from random power FET firing.

I'm very satisfied and confident that I can proceed to test various emulsions with this ignition system. I'm able to easily change CDI Cap values and can improve the efficiency of the voltage multiplier. My R1 resistor is 120 Ohms x 10 Watts and barely gets warm so this thing is drawing very little power. The main components in the oscillator are rated at only 5 Watts and just lope along at only modest temperatures ... warm but not hot.

Peace,

Greg

P.S. I will begin conveying the details of all of the circuit and circuit elements soon ... me pooped out for now though.

[ashtweth]

NICE man
More good news to go with Gregs

Rev's Vexus is installed in the Toyota with the booster and the light bulb and draws 8 amps only a full RPM. WE noticed ALLOT OF POWER

Gonna run it for a week and see if there is any wear or back fire
Will post a snap tomorrow. THANKS GREG

Plasma vs pressure

Hey guys,


Here is something I found interesting enough to video the effect. I obtained a cylinder combustion test plate from a friend of mine that bolts onto a cylinder head and allows simulation of combustion chamber pressures. I did this test at 2,300 rpm and only one of eight plugs setup to fire plasma. I pressurized this chamber at 100 - 110 psi, using VERY dry air from the dryer system my painter uses to paint cars. Because we all know what happens with plasma and moisture! As the pressure increases, so does the size of the plasma! I thought compression would decrease the effect, but I guess not now. I wanted a longer video, but the battery in the camera died, so I just went ahead and posted it as is. Enjoy, and please give feedback as to what you guys think of this.....................................Mike

Vexus Plasma Vs. 100 psi

Great vids Mike!

Is it a bigger plasma ball or a brighter one?
Because from a camera point of view it would look about the same.

Also, have you looked at it through a soldering mask or the like?

Ansis Freimanis as suggested and I am wondering what it would be under vaccum... might be an informing comparison to tube.

Thanks for sharing, your vids are interesting, as usual.

Just an update.
After I successfully found the optimum timing for my genset using my custom ignition system, I was able to get about 16% fuel economy just by correcting the timing compared to the stock magneto system. Then I just add a HV diode from the positive terminal of the cap to the HV output of the ignition coil like this:


This did intensify the spark, but just a little bit. Because the cap value is not great and they are charged just to about 300V and most of the charge discharges through the ignition coils secondary winding. Nevertheless the small intensified spark gave 2.5% fuel economy ans this time the results are correct. Now I will try to attach the vexus circuit to boost the spark much more and we will see what that does.
Thanks,

I'm sure, your setup ability to change engine's timing will give optimum efficiency that appear in gas saving. As what Greg done on his VW, your nice setup is very neat. Amazed...

[Jetijs]

Thanks Rev

For those who experiment with water spark circuit on gensets I found a safety feature on my generator and I am sure that it is so on most of the generators. If I use my custom ignition system, I can run the engine just fine with no load on the generator side. But as soon as I turn on the generator, the engine just shuts down. At first I could not understand why this this is happening, I thought that maybe the timing is wrong. I tried the original magneto ignition again and it just worked fine. Turned out that as soon as I turn the generator side ON, the genset brain checks if the original ignition switch is on or off. In my case it was OFF and the genset thought that there is no point in pumping fuel if there is no ignition, because it does not know that there is a custom one. So if your genset engine turns off when you switch the generator on, then you need to flip the original ignition kill switch to off.

Hi J,

I like your oscillator circuit. Where is the oscillator-only circuit? I'm now convinced that we need 'pumps' not inverters ... how 'bout you?

Greg

[Jetijs]

Hi Greg.
This is the basic Bedini self oscillator circuit:



But you should know that I am using this only to make an ordinary spark for my custom ignition/timing system. I still need to use a vexus booster. The Bedini selfoscillator is designed so that it outputs mostly voltage potential from the collapsing magnetic field and just a little current. My setup consumes only 100mA from 12v battery, that is about 1.2w of power and almost the same amount of power we get on the output just with higer voltages. It consumes that power regardless of the load, I can short the output and it will still consume the same power. This small power will not create a strong plasma. Of course it all depends on the coil wire size, winding count and resistor values. It is basically a dc to dc converter. But if you need an output power of 40w or more, I think that your circuit is the way to go

How many HV Diodes do You think is optimal for 1 SparkPlug?
Thank, You!
