Water Sparkplug

[turbotrana]

I see this plasma ignition system as being one component out of three to getting alot better fuel economy. On its own with no other adjustments you will certainly get gains but not the full potential from my own experiments with the ICE

I think the main gains will be in the ability of this spark to burn really lean mixtures i.e the 18:1+ a/f ratios. This is where I see the main economy gains. Its easiest to experiment with a fuel injected car. You need a programmable engine management system with wide band A/F ratio meter where you can see whether the plasma spark is able to fire leaner mixtures compared to a normal strength spark.

Also if you are running fuel injection I have found good gains in the type of injector used. The bosch EV6 injector atomises the fuel better than any other common injector on the market that I know of and it gives REAL gains. If your car has the older EV1 pintle injector a change is very worthwhile.

Lapper are you able to give a diagram of your final setup.

In Aust we only have 240volt inverters. How would I mod the circuit to accomodate this.

My car would be perfect to test this ignition system as I have programmable engine management system/wide band a/f ratio meter and I have been experimenting with lean burn/economy tuning for the last 6 months

I did the test and the paper mass is too great for an ignition but I did get a burn speck on the paper. I'll try and photograph it and post.

Hi all,

Here are some pics of the paper burn specks.

The circuit is VexUs using 3uF CDI cap, a 22uF storage cap, homemade two transistor oscillator / inverter with voltage doubler (diode - cap ladder).

..... then I put the paper back and ran it at high speed for a couple of seconds ....

Hi Greg

Thanks for the test. I was also able to burn through the paper, I though I mention it as it could be important in what we are trying to do here.

Hi all

I have been observing the effect of the plasma sparks for the last 2 days.

The simple test is...

Spray some alchohol inside the cylinder of a 2 stroke engine. No carb, no muffler, Im just using the engine to compress the mixture.

The result is definitely a stronger explosion. Tried with the piston at the bottom, a larger flame spits out of the exhaust.

I also tried this with light oil (penetrating oil), the plasma is able to ignite it. Black smokes and it smell like diesel engine under acceleration

Tried with veg oil, there is a small movement of the piston.

Tried with water, nothing.

The only way for it to ignite water is to mix it with fuel, I used alcohol.

This is why I believed that those who tried with water and got some piston movement, I think its due to some fuel still left inside the engine.

Im not too sure if someone have tried before but I will get some diesel fuel and try to ignite that with plasma.

It can surely ignite lean mixture so thats good news.

diesel fuel

@Chris31

Revizal has done some work with diesel in a standard gasoline engine with very positive results. It would be great to get some secondary verification.

Check out Yes! Water is Fuel for a compact overview of the past three months development. I have linked to several of his videos on you tube in the archive.

Branching

I just wanted to note that with the success of the nexus and vexus circuits we have passed phase one of the development process. With the recent suggestions for improvements from Luc and Naresh it appears we are fast approaching the start of phase three and looking like a couple of new branches on the tree.

This is excellent progress so everyone should be very satisfied with the pace of development so far.

Hi! I am making my experiments with 1 n-p-n Darlington transistor and 30-40KHz frequency and all is fine. I look at Your circuit and I think You make good choise- You put Lamp 100W between bridge and transformer ( in UPS is this kind of circuitry). It is very right becouse (some experimenters think the spikes from Spark plug make the "dead inverter") but my understanding is little bit "upside- down"...
I think inverter go dead when no load is happening. It is between discharge: voltage is jumpig up and down and in this moment voltage go high too much and all this make transformer to saturated condition. After this core start heating up and primary current go up, up, up and... dead.
When You put 100W lamp between- it make "always load" situation. No process of saturation.

Yes, I saw yours and this's very interesting to find the best way to supply voltage to the circuit. A 100 watt lamp is a good way to supply continues power to the circuit but it make not just a simple one which we need. I think the right way is what Aaron done on his lawnmower with a resistor. A simple calculation, if we put 220 V to the circuit and want to keep 0.45 A we need 100 watt load on it (such 100 watt bulb). With a resistor it must be 488 Ohm (100 watt rating) displacing the bulb to keep 0.45 A current. This is a minimal requirement. I donot know what the actual fact, because I donot have a 100 watt or more rating resistor.
But the basic situation is what you said before that we need a continues loading stuff infront of the the inverter to make it worked. No matter how, by using bulb or resistor or anything else.

Hello everyone,

Wasn't here yesterday, busy moving into new house. What a job that is turning out to be! I have not tried anything with the circuit since Saturday. It is possible that my inverter was making contact with one of the bolts on the fan shroud where it was sitting. I did have the isolation transformer strapped to a metal box mounted to the front of the Suburban, that was surely making contact with vehicle ground.

Now, about moving the resistor to between the inverter and bridge, or voltage tripler in my case. If this will better protect the inverter, I'm all for it! I just got in four new slide resistors, 100 watt rate and up to 250 ohms each. With the voltage tripler I am charging to about 425VDC, how much resistence should I use? And should I move the resistor from it's present location between the bridge and capacitor, to between the inverter and bridge? Before or after the isolation transformer?

Excited as always to do new tests and further the circuit, looking forward to hearing you guys' thoughts. Later...................................Mike

To jstadwater

If You have inverter + Isolation transformer, than You must put it after isolation transformer- before bridge. (I think so).

[jstadwater]

Thanks,

That's where I was going to try it, after the transformer, just wanted a second opinion. If I fry another inverter I'll just add it to the group already on the floor.

I will try it initially with 100 watts @ 200 ohms resistence and see what happens. Another question to anyone who may know. If the resistor is moved to the new suggested location, in front of the bridge, will it still play the same role as to limit the charge time of the capacitor? OR with it in the AC side of the circuit, would we have a wider range of resistence to play in without cutting our charge time to the capacitor?

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

[Jetijs]

Mike, you need to put the inverter protection resistor after the isolation transformer and leave the rest of the circuit as it was, because if you remove the resistor between the positive terminals of both caps, you will be limited to 120Hz frequency (rectified 60Hz) that the inverter puts out.

Edit, but I think that you do not need it at all, because your tripler caps are the load that is always there and the full discharge happens only in the small capacity cap. If you used just the inverter output rectified current to charge the cap and then discharge the same cap into the spark gap, then you would need the resistor between rectifier and inverter, but for the vexus circuit you don't need that.
Jetijs

[jstadwater]

Thanks Jetijs,

I will leave it as it is. Your explanation of the tripler circuit makes sense to me. But should I raise the resistence from 100 ohms to 200 ohms, still 100 watt resistor? I am not using a "storage cap", only voltage tripler and then three MW oil caps in parallel, totalling 2.5uF as discharge. My slide resistor is in-line from the voltage tripler pos+ to pos+ of the 2.5uF discharge caps. I am almost finished with the install of the new inverter inside the Suburban's cab. (making sure nothing touches ground this time). UH-OH, I'm down to three inverters in stock, must..............get...................more...... .....backups. Maybe I won't fry anymore of them. YEAH, RIGHT!!!

Well, back to play, I mean work.....................................Mike

[Jetijs]

I am not certain about that, but you can try that out. You wont damage anything with higher resistance, the smaller cap will just charge slower

[jstadwater]

OK,

Got the circuit hooked up and functional in the 5.7 liter Suburban! Inverter IS NOW isolated from chassis ground, got it on a 1/4 inch thick piece of rubber! It definitely makes a difference when you flip the inverter on. Pressing the pedal down quickly, gives a serious spark knock. That tells me the plasma spark is igniting the gas allot quicker than normal and I will have to retard the timing to make up for the quicker ignition. I was hoping to have this problem! Best of all is that the inverter still LIVES!! I turned it on first, then cranked the engine. Also cranked the engine first, then flipped the inverter on. Inverter is happy either way, very good news. All the gauges work normally, forgot to check for any noise in the radio. When I rev the engine, slow enough not to get spark knock, it is very smooth and sounds like it has bigger kahonees now. Tomorrow is another day for testing, time to go home now and move some more stuff to the other house. Almost done with that, but then there's arranging it all again! Till tomorrow..............................Mike
