My s1r9a9m9 replication!

Chapeau! I shout a big "Respect" for this video-demo!

It shows, that the motor would run, but has problems sustaining the higher RPMs.

Maybe the motor doesn't get enough water to sustain the higher RPMs?
I personally think that most probabely a Plasma-Water Engine needs much more water than it would need gaz.
(As an example I see the youtube vid where one does see, that you get really quite big explosions if you use quite a big amount of water...)

Another reason could be, that the caps do not get recharged fast enough, but this would be easily checkable with an oscilloscope. But the kind how the motor dies, in my opinion more speaks for the out of water theory...

Maybe trying plugging a humidifier output to the air inlet of the motor would help. Just a guess. If it works better, excellent, if not, one point to draw from the list 

And maybe adding a starter motor, would help adjusting, for you have a continuously defined condition.

I have taken very little trials with steam, change is obseverd but not confirm. better performs ....

Problems observed with water only (not steam)
many times it needs to clean spark plug, or wait until water on tip gets burn with LV DC, shorting of tip with water creates problem.
Diodes 6A4 gets very very hot and melts solder joints, but does not fail.
capacitor gets little hot, may be diode heating causes this problem...
rectifier must have higher rating...I dont know why 6A4, 6A10 diodes get shorted immidiatly as soon as I turn it on, but 1Amps 600V bridge rectifier worked..
I am using 50Amps rectifier and 330uF capacitor

Well that doesn't sound good.  What are the switching times of these diodes? Maybe they're too slow...
Or maybe if the plasma is really well developed and the resistance of the arc is almost 0, all energy gets dissipated in the diodes (instead of the plasma), which have quite a high voltage drop inherent.

To get rid of this, the only simple way I could imagine is to switch to a pure Trigatron-Scheme, which doesn't need diodes...
Or to try to damp the HV Spike right in front of the LV circuit with the help of some snubber cap, to protect the lv part without any diodes...
Surely then the HV first hast to reach the plug before it goes to the snubber!

Another idea could be to try to protect the lv part just with a small inductance. But this could be very critical in respect to the correct size for timing...If the inductance is too small, the lv part gets surged, if it is too big, the LV part isn't able to feed the arc soon enough, and no plasma will be made...

Bute these are just some ideas...

@Cap70
Is that small motor on your video a two-cycle motor?  It kind of sounds like it is.  If so, are you using soluble oil to lube the bearings?

Were you able to adjust the timing of the magneto or are you using an external  automotive type ignition?

I have an electric start two-cycle engine, but i am wondering about rust and lube to the bearings in the crankcase.  And, also how to adjust the timing in a simple way with an magneto.  Of course, I realize each brand of motor is unique.

Thanks

It is four stroke 100CC two wheeler engine.

ignition timings are not modified.

Two sroke engine is not sutable for plasma system, water stays at bottom of piston.


These are some photos of carburator.

Which part of carburator is needed to modify to get it continuously running ?
I am not mechnical engineer please explain in detail, dont confuse me...
When I give choke it starts, without choke it dosent work at all....
