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?
It is four stroke 100CC two wheeler engine.

Were you able to adjust the timing of the magneto or are you using an external  automotive type ignition?
ignition timings are not modified.

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.
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....

Please explain me with reference to Jet diagram from above images, I am not mechnical engineer, I need to make big holes to all these three jets ???
Circuit used in working model.

DO NOT FORGET BULBS

Capacitor70,

YES, but you may be able to buy larger jjets which can simply be screwed into the holes.  Use a scewdriver to remove the old jets, and replace with larger sizes.  I would try to get larger jets, before drilling the old ones.  You may be able to carefully  drill  the jets out holding them in a vice.  HOPE THIS HELPS.

Would you post your electronic circuit clearly for  everyone on the group?

Ignition coil must generate +ve

DOH!!!!  I think that was my problem!!!
So... i will take the coil wire form the motor and put it to the base of the plug and then a wire from the block to the top of the plug, where the DC comes in. Do ya think that would solve my problem?

Ignition coil must generate +ve, It is very simple just swap input wires...

Very Useful info From Unicorn
on this image the middle copper nozzle (tube with little hole)
it has a number on it. if you look good you can read 82 or 83.
this is probably to small, the higher the number the bigger the hole the more gas it will suck in to the engine maybe you can try a nozzle 90 or 100 maybe bigger they should be verry cheap so you can maybe buy 90, 100, 110, 120  and play around a little to get best results. if you find one that works the best you can fine-tune
for example 100 works but not realy stable and 110 floods your cylinder with to much water you can get 101 and 102 and test what works the best with these.

Tommarow I will buy some jets, Numbers are there on each jet

Capacitor70

Hi,

Been folowing this for a while and doing my own experiments, I dont know much about electricity but I own a mechanic shop and know my fair share about engines.

What is beign explained to you is this:

You state your engine only runs on choke, When the engine is choked it is requiring a richer air to fuel mixture. Most motorcycles etc, require a good choke until the cylinders get warmed up to provide a better cumbustion of the fuel. If it will run for a longer time on chojke dont worry about it. Let it be choked and se what occurs, What the person who posted the pics is trying to explain is that those are your jets. The jest provide the passage for the fuel to be delivered to the combustion chamber. By makes the holes in the jets larger you would provide more flow of fuel, hence instead of choking and removing air flow you are just adding more fuel to the air flow you have. When you choke an engine you are decreasing the air flow to increase the fuel to air mix. When you increase the jet size you are increasing the fuel, thus increasing the fuel to air mix.

In order to help you more i need to better understand how the water is being delivered to the engine.

are u connecting the water line to the same hose the gasoline came from?? if so then what i am stating is all correct. If its just a hose pouring water into the carberator than disregard my text.

another thing to ask is did this engine idle and run fine on gasoline. Carburators are funny things and if it didnt run well on gas dont expect it to on water fuel.

You may notice that i accept water as a fuel. Thats because i do, I am also an ASE master tech and accept this, which you will not find many of, congrats on the work, I hope to help you mechanically and perhaps you can help me electronically.


In regards to earlier post about the flywheel coil breaking of engine etc. Perhaps u can use parts off and old car distributor, all that is is a halofect switch and a coil. us the halofect switch from the distributer and a motorcycle coil. or the coil u had that broke off and use the distributer parts to rebuild your ignition system, the nice theing there is that it would eb totally adjustable timing wise

thanks for your time

Tim

and this is my ver first post, so i hope it helps some people

P.S

i see you are posting pictures capacitor70

Is it possible for you to tell me the engine u are using, IE the bike it cam off of. I can then get you some pics of the carbuerator and some better explanations of how it all works, I have allot of things at my disposal as for engine information.

I agree that the carburetor must be tuned for this application.
First thing is to increase the size of the idle jet (for fuel) and test. It is also a good idea to unscrew the  idle mixture screw a couple of turns. This will have effect in idling and the transition regime.
The next is to increase the main jet, as the others said before me. Do not confuse the fuel jets with the air jets. The air jets don't need to be enlarged.
The main jet helps engine when throttling from, let say 2000 to 4000rot/min.
Pay attention to the float level as well. If too small, it will be hard to accelerate. If too high, the engine will suck fuel (water) trough the main jet too soon, getting worse mpg.
Yes, we need to know the type of carburetor to talk more specifically.
Maybe is a good idea to treat the water by passing it trough a small HHO cell, prior to send it to carb. That will help the water vaporize better and release easier the Hidrogen and Oxygen to be burned by plasma. Or at least heating the water through a copper pipe coiled to the exhaust pipe or the radiator hose, for better vaporisation, at least in the winter.
Capacitor70, I can't wait to see your engine running smooth, after adjusting the carburetor.
Good luck!

P.S:
What type of water do you use? Distilled? Tap water?

The ignition coil voltage is VERY important.  Most of the time it will be nagative, but we need positive otherwise the diodes will hae to be reconfigured.  This step should be highlighted.  Also jet sizes increased is a must for revving.  Good work and congratulations on being the first to replicate, if not second.

Then use saperate ignition coil, like I am doing.

Its tap water. (bore water)

I don't think is a good idea to use tap water in the carburetor... Sooner or later, the salts and chemicals in it will be deposited in the carburetor (jets, circuits, transition holes) and will decrease the amount of water delivered to engine.
The best for carburetor would be distilled water, or mounting some sort or demineralizing filter (magnetic ?) for water, before the carburetor.

When I look at your schema you're currently using, something does light up to me.

After the bridge the DC will be a 100Hz only pos-side sine-signal. So if the firing rate gets higher than this frequency, you will have e severe problem, for the loading voltage of the cap will change with the current sine voltage, so you will have a very uneven firing, with some firings at very low cap voltage (could be even near zero!).

So my suggestion would be to use either a much higher freq AC-signal. Or to us some big cap-battery after the bridge to have there a stabilized 320VDC, and to charge the firing cap with the help of a FET from this DC level. And the FET should obviously be in 0ff condition when you want to fire. Otherwise qour whole cap battery gets discharged in the spark...
A simpler solution would be to insert a resistor between the cap and the cap-battery to restrict the amps flowing from the battery, when the arc has established. At the same time, this also restricts the loading current for the cap. Which ist good, for the cap. But the loading time should certainly remain smaller than the firing rate...

Just again some thoughts by myself...In case anyone is interested...

But as I calculated, usually the firing rate of a ICE is not very high, so it most probabely can work directly with only a bridge rectified 50Hz AC, but it would surely then have some 100Hz Power differences overlayed...

Today I have taken trials with my 125CC 4 Stroke bike. Its not starting at all with water, not much bulb glow (may be plasma is not generating properly), not a single fire is observed. Spark plug gives good plasma checked before putting it into bike.
Then I given gasoline to start it normal, but it is not starting on gasoline also.
I have not checked spark plug after trials, Then I started plasma, still it is not running not a single fire, but suddenly it given a very very huge blast, sound came from silencer.... Blast sound is very very loud my neighbour come to my home to see that blast...I am scared to start it again....

Probably residu off gas in exhaust that exploded maybe an Afterfire/back-fire

can it be you have a leaking valve? or maybe the spark is also sparking somewhere it should not?

Did your bike work well before starting these tests? If so, then you need to make the same adjustment of the carburetor as said earlier: put bigger fuel jets.
Also check the needle valve in the float chamber.
Could it be a timing problem? Check the proper tuning of this system.
Use another sparkplug outside the engine conected with wires and check the presence of the spark/plasma, trying to start the bike normally.
Try to clean/dry the carburetor after you use water. If water remains in it, the gasoline will pass very difficult to the engine, sometimes beeng blocked.
Could you make a clear photo of the sparkplug electrodes? One that had been used in that bike before testing with water.
The backfire occurs in the manifold. There is another type of problem, that makes big explosion-like sound in the exhaust pipe/muffler. Its cause may be the wrong timing, weak spark or carburetor running rich.
It seems that changing the fuel type recquires a lot of tuning...
Good luck!

Working hard to get it run..... Plasma system is on the bike, tomorrow I will take more trials.
as I told earlier water shorts spark plug, spark plug must get wet but not shorted with water on its tip. this create problem.
