Water Sparkplug

[gotoluc]

Luc,
The AC of the alternator is 3 phase. Is there a way to convert it to single phase to power the MOT?

On my set up. I run the AC through a 3 phase bridge rectifier to get my HV DC.

Hi LapperL,

I think there are 2 ways to do it. One way is to have the 3 phases in series, this way you have higher voltage but less current and the other way is all phases grouped in parallel, low voltage but high amps. I don't have the answers as which way would be best. One would need to test to find what works best.

BTW, good video. Thanks for sharing

Wirewound power resistors that have a slider tap retain their wattage rating since that is determined by the guage of the nicrome wire used in their construction. The only difference moving the slider does is change the resistance due to reducing the total resistor length, the wire guage is constant from one end to the other. The voltage drop across the resistor will vary with the same current, but the wattage handling will be retained.

@Nxus,

I hate to disagree, but from the research I have done, I would have to agree with Insane4ever. The wattage does decrease incrementally with the resistance. Please review the pdf data sheet that I have attached. I have highlighted to pertinent information.

@jstadwater,

The resistor controls how fast the cap is being charged, the more resistance that you have the slower the cap charges. When dealing with multiple spark plugs and one cap, the resistor will basically control to what % level you will charge the cap to. Too much resistance and the cap will not fully charge between spark plug firings. This is what Gmeast was explaining in his previous posts on how to size the R1 and C1 at certain RPM's. Depending on the size of your resistor, you probably won't see a decrease in spark effect until you reach higher RPM's and the cap charge percentage decreases.

Hope this helps you to understand,

LapperL

Great news!

YES, YES, YES..........I got in the 1.5KE150CA diodes in a little bit ago. Hooked up one between the inverter and isolation transformer, and then one between the transformer and tripler circuit. Have not added the one for the battery to inverter yet, but will shortly, just as a safegaurd. I could never run the circuit on just the inverter for more than about a minute at around 2,200 rpm, less than 30 seconds at 4,300 rpm, and the inverter started squeeling loudly in protest.

I just finished running continuous for 20 minutes at 4,300 rpm, powered by inverter ONLY. The 1.5KE150CA diodes did not even get WARM at all........much less hot. But, most importantly, THE INVERTER WAS HAPPY THE ENTIRE TIME!!!!!!!!

NOW.......if I can run a v-8 distributor at that rpm on inverter power, there should be NO problem whatsoever with a 4 cylinder install.

I will now move forward with installing the circuit into this 350 Suburban, HOLD ON TIGHT BOYS, IT'S GETTING CRAZY AROUND HERE!!!!!!!!!!!!!!!!!!!!!

Later.......................................Mike

Hi Mike,

This is VexUs's daddy, could you please tell me exactly how you hooked up both diode types? Can you post some photos please?

Thanks,

Greg

Hi All,


Sorta like a rubber band being stretched out and then letting it snap back together .Peace out

Welcome aboard,

I would guess it would you serve you to breeze the posts from the beginning as this will provide a foundation.

There is a group of youtubes that chart progress with the circuit.

Numerous circuits have been posted and still more have been demonstrated on video.


What the effect is remains a topic of debate. After this research you may want to weigh in on a potential conclusion.

I don't think the above would take more than an hour.

YouTube - Water Sparkplug IV

The above youtube is by Lee. He also provides the circuit and a few possible conclusions.

Bill's Nexus Circuit Test Two Update

I finally received my isolation transformer today and performed some testing. I first tested the circuit with an isolated battery to ensure that the inverter primaries were isolated from it's secondaries. It worked just as I expected. The hot side of the inverters output is totally isolated from the vehicle battery, the neutral side still reads 120 VAC but I guess it should seeing that it is tied to the vehicle ground. So when I tested the circuit on the vehicle battery, the inverter held up just fine. I was a little worried due to all of the TVS use that has been going on, but I figured what the hell I'll give it a try. It did not seem to affect the inverter, but I was only running one plug. Just for safety sake, I think I will order TVS's just to make sure.

I also replaced the MOT with an electric motor coil that I got out of the fan in the microwave. The spark was not as great, but that should be due to the fact that the MOT has 0.7 ohms of resistance and the little coil has 103.7 ohms of resistance. The little coil worked just fine and of course is 10 time smaller.

I only used 15 diodes in this test because of just testing one plug, and that also worked fine. I found a neat way of packaging the diodes. I soldered them all together covered them in liquid electric tape, then folded them and wrapped them in heat shrink. Works great and a lot smaller package I have posted a couple of pictures before and after the shrink wrap.

I made a video of the test and I'm in the process of uploading it as I am writing this. I will post a link once it is completed.

Next step is to install this on all four plugs and see how she runs.

Hey NXUS,

The basic VexUs circuit is posted on page 49 of this thread. With the TVS diodes drawn in.

[jstadwater]

Oooops!

In my haste to test the circuit, I have the clips hooked up wrong.........DUUHH! I accidentally ran the voltage through from end to end on the resistor! It's been a long day, and I didn't get enough sleep, we're moving into a new house. Everything is upside down, here at work too evidently. Later.................................Mike

[NXUS]

Any chance of seeing a circuit diagram? Has it been posted, if so can you link me to it? Sorry to hear about your meltdown...

[jstadwater]

OK,

How would I verify the ohms level while the circuit is charged? (not while making plasma burst, just with voltage present, 460VDC ) I moved the slider to each end with no visible affect on the plasma bursts. I thought different resistence levels would change the effect. Although I am only discharging 2.5uF, maybe not enough capacitence to notice the change in the plasma effect. If that's the case, will different resistence levels, one way or the other, adversely affect my inverter? Still trying to understand.

@ Jetijs

Nope, no good without the isolation transformer! $40.00 test just completed, the smoke leaked out IMMEDIATELY. The plasma effect was about 5 times increased though, (go figure) both flashes then nothing but the itsy, bitsy factory spark. I too, had to know if it would work or not. But I do like the diagram of using the two MOTs to make a isolation transformer, at least they are practically free!

I will probably start the install into the Suburban tomorrow sometime. Later............................Mike

Thanks Arron, makes a lot of sense now. When you mentioned the plasma first thing came to my mind was, well that is still a local effect how does that help burn fuel at the outer limits of the chamber. Then you mentioned the lorenz effect, and it makes it workable. Kewl, learning already

Just wondering if the propagation speed if sufficient for high rpm rates?

Would a custom sparkplug with a pair of isolated electrodes simplify implementing the plasma, without having grounding issues etc.?

[insane4evr]

Thanks for the comments guys,
........I have a question. I purchased a 100 watt, 100ohm slide resistor. I get a much cleaner and more robust plasma burst using it instead of the 100 watt light bulb. I moved the slider from one end to the other, the ohms measured the same, and hardly any noticeable plasma difference. If the adjuster is in the middle of it's travel, does that mean I am at 50 watts power and 100ohms resistence? ....

Hi Mike,

When using the slider, resistance is between the slider and one end terminal. With the slider at the middle and connection is between the slider and one end terminal, wattage will be aproximately 1/2 of total wattage rating and resistance is also approximately 1/2 of end to end terminal reading.

Make sure slider dimple is making good contact with the wound resistance wire.

[NXUS]

Forgot to mention that the reason that the resistor vs lightbulb may have different results is that the bulb probably has a higher inductance than your much larger wire wound resistor. Filaments are usually coiled to make them smaller. Not sure what the actual value would be though.

plasma effect

Is the goal a hotter spark or is there a specific property that you are trying to achieve?

Hi NXUS,

Any help or assistance is greatly appreciated.

This plasma is faster and takes up much, much more volume than a conventional spark. With super lean mixtures, the flame prorogation speed is too slow to burn much but the plasma, it can fully burn a leaner mixture.

This plasma does have a very interesting effect on plain water and it does appear to "crack" the water on contact, burn the hydrogen, then it recombines, which is explained very well in several patents including NASA developments on almost an identical method from the late 1970's.

But, with enough punch on the low voltage side, the Lorentz force ejects this plasma away from the plug far into the combustion chamber.

This ignition method was even shown to be able to run a gas motor with diesel! The youtube link is here somewhere...that is a very strong testimony to the power of this plasma.

Maybe Ash has a document somewhere that has summarized most of the developments on this so far.
