Water Sparkplug

[insane4evr]

Hi Graham,

Yes I get more than 10:1 without a load too. Those resistors do get hot and as long as they are 5 Watt they should be fine. Do you know what your frequency is?

Almost everyone says that design draws too much current and they have gone to another design. I also just purchased the parts for the "better" oscillator/inverter. It is supposed to draw 1/2 Amp just sitting there. I will keep using the one like we have for a while though. In the mean time here is the newer - better (I'm told) oscillator/inverter circuit.

The 2N1305's should be MJ2955's ... they are the PNP compliments to the 2N3055. The circuit you have already built is one I pulled down off of the internet. This newer one was posted here earlier this month or last.

The components on the output look like a voltage doubler. I got confused when I first saw it. The output of the transformer should only be connected to the doubler and the VexUs circuit ... not to chassis ground like in the picture. We have to maintain the isolation amd only pin the '+' side of the "V" circuit to ground.

Peace,

Greg

In pmonk's circuit, searching in nteinc.com site, an equivalent for the 2N1305 is NTE102. I am not sure if this is better and/or more cost effective than the MJ2955. Just my 2 cents.

Inverter Circuit

Greg,
I just built the oscillator circuit that you showed in the last picture. I did have only MJL2501 PNP transistors, so I used them as PNP transistors. Instead of 12k resistors, I used 16k resistors. And my oscillator caps were 0.1uF instead of 0.047uF. I used a transformer form computer UPS. When I started the circuit, I measured 250VAC on the transformer output. I am not sure about the frequency, but judging from sound the transistors make, it is high. Unloaded the circuit consumes 600mA at 13V. The only load I tried so far is a 25w light bulb. It lights up good and with this load the circuit is consuming 2.3A at 13V It seems to work great. Thank you for posting that circuit

Hi Jetijs and all,

Well I got it finished and am testing. The quiescent power is 250ma @ 25.5 VDC I'M STOKED ! The original post -here- was Phil, aka pmonk. Thanks Phil. It does what you said ... THANKS !

Dave.. Try what we do just say its for scientific research,

Chris,

These are the specs for the plug:

Champion RDZ19H
10mm
3/8" reach
5/8 socket

I called Champion to find a non-resistor plug. When I told him I wasn't too concerned with the reach (determines if it's a hot/cold plug), he asked me what I was burning. I told him I was trying to ignite water vapor. 'CLICK'. He hung up on me.

Dave, that is

Hi Jetijs,

This is funny ! I'm still getting the parts together and building it as I am reading your post. One of our regular members here posted it last week or before. I need to give proper credit ... need to go back and look for him. It sound to me like it's performing as he said. Thanks for building it 'cause I now feel good about building it too. GREAT !

Thanks,

Greg

fun

Hi Greg, thanks for the walk through man , that's more proof our little spark is not doing some thing normal. I think your work is the best purist work here so far for the plasma water engine. We have the GEET finally fitted and ill be adding hydroxy and plasma spark then doing some run time tests, only cause you guys are better at doing the 100% water then us. . Thanks again for the Feedback Greg.

Ash

Hi Ash,

You're welcome and I hope to have the oil leak on my Bug stopped up soon and then it's back to testing. I hope to get the water way up upon resumption but I'm happy AND surprises at the results I got !

newer circuit

hi greg

i built your ocsillator/ inverter. very pleased to say that it runs! it puts out about 25VAC from each side to the center tap on the primary. my transformer is just more than 1:10 cos i get 270 VAC out at the end(without any load yet, i need to build the rest now)!

it draws 3.5 amp of a car battery just sitting there, but the 10 and 180 ohm resistors get very hot, way to hot to touch. is this normal?

thanks

water mist

HI Aaron, i had been away on the weekend, can some one point me to where the figures of 40%+ were achieved(i assume Greg's) with the ignition and water mist? ill add that to the PDF summery, can't seem to find the post. Thanks for the back on track post mate.

Ash

Hi Ash,

I have tried water mist before and got nothing. I truly believe the fact that I aspirated 'steam' has a great deal to do with an increased thermal efficiency which accounted for the increase in mileage.

If I may present the scenario:
I recuperate waste heat by turning water into steam. By doing this, I avoid the conversion penalty associated with the 'heat of fusion' ... that is the heat a substance, in this case water, absorbs before it changes state, in this case water to steam. This heat energy can't be recovered with a condenser ... it is therefore a penalty ... the 'steam penalty'. But I do this external to the process with (otherwise) waste heat. With the steam (gas) combined with the air and fuel, ignition occurs (thanks to the intense plasma spark) and the combustion heats up 'both' the steam and the air, but the steam is like an inert component that can absorb allot of energy. So it does and generates pressure in exchange. The pressure from both the air/fuel and the steam is about the same as it would be by just the air/fuel itself because it at a lower temperature. This is where the increase in thermal efficiency comes in ... it is a system thing:
The pressure ratio (compression ratio) is the same. The efficiency of the energy extraction (power stroke) is thus the same (p1-p2)/p1 ... if the ending pressure p2 is much, much less than the starting pressure p1, then the efficiency is high (that's why a high compression engine is efficient). The same is said for temperature (t1-t2)/t1. But what does this do for us? Well - the engine runs cooler with more energy being converted to output power because FAR, FAR less heat is being rejected from cooling the engine.

In my tests, after the engine warms up, you can place any cold plate at the exhaust and the condensation is about 3 - 4 times the amount of water as usual. The EGT is also cooler by at least 200 Deg F. But you don't get consistent running unless you use a plasma spark. I can run so much water (in the form of steam) that the normal spark will misfire. There is some inherent fuel/air leaning going on here also. If I aspirate the steam after the venturi, then the fuel/air ratio won't be affected ...this is my next step. BUT YOU NEED A PLASMA SPARK TO DO THIS.

Thank you

Hi DonL,
I used LTH301-46 optointerrupter. It looks like this:

But you can use any optoswitch that you can find. Just look at the datasheet of that optoswitch and see the output collector current rating, the higher the better, that means that it can handle more current on the output and will be able to turn on/off more powerful transistors without a need for amplification. Mine can handle 20mA and is used to turn on an optorelay that then triggers the thyristor (SCR). Also look for those optoswitches that have the widest gap between photodiode and phototransistor. Mine has a 3mm gap, but the wider, the easier to work with them

I just ordered all my parts.

Thank You for all the help!

DonL

Just forgot a small detail: Tesla always suggested use of water on caps to enhance effect of sparks.....
