Water Sparkplug

[jstadwater]

Yeah, but..................might be a little hard to get it to fit inside the engine!!

Hi, friends!

I have an idea. Maybe we can replace HV diodes with spark gap? I think this can work. Greg, how do you think? Spark gap is more "simpler" and if its work than we can through out HV Diodes.
What do you think?

Hi Ansis,

That's a very good though. I can try it. The gap would need to be appreciably greater than the spark plug's gap. However, not so much that it prevents the spark at the plug. Something tells me you need a very HARD WALL (positive barrier) like provided by the diode(s). It may just end up broadcasting a very powerful radio pulse.

Hi everyone.
I don't think the air gap trick will work.
It may on your bench test, but inside the engine, the HV sees a much larger spark plug gap than we can measure between the two electrodes. And that is because of the air compression in the cylinder.
I did some experiment using plasma and air gaps.
For example, I put the HV electrode at 10mm to the ground one. After that I put the plasma electrode (the diode string coming from a capacitor charged at 400V) between those two, so that it was at a variable ratio. I get two sparks: a regular one between HV and plasma electrode and a plasma type between plasma electrode (diode string) and ground.
I changed the string with an old one that was surge burnt. No plasma until string electrode was at 1-2mm from ground. Only the regular spark between HV and string electrode. No discharge to the ground electrode.
My conclusion is that is very important the electrical insulation of the capacitor from the HV pulse.
If you use only air gaps but without some form of uni directional driving of the HV spark, it will not work.
All the best.

Hi Kinetix,

I now recall performing a similar experiment. I didn't use any pressure but I did change the distances of the (simulated) spark plug gap and the "diode" gap and drew the same conclusion ... you need an actual diode(s).

Thanks,

Greg

to Greg and Kinetix

Thank, you. It means this trick is not working.
It’s good to know, because HV diode is the next weakest point in the schematic.

[gmeast]

diodes

Hi Ansis,

There will always be some weakest point in any circuit. I use 4 parallel HV Diodes in my circuit to give me over 2.2 Amps passing current. That is many times the current being passed from the circuit reference voltage of -400 VDC. The group never gets much above ambient temperature ... ever. It seems very solid.

Thanks,

Greg

Hi all
Today I did some experiments with burning gasoline fog made by a ultrasonic fogger. Here is a video:
YouTube - ultrasonic gasoline

I must say that when the fogger is turned on, the flame gets much bigger, but by burning, some black smoke is created, this does not happen if I burn just the gasoline vapor without any help of the fogger. It might be that the smoke is just not noticeable on a such small flame, but it seems that gasoline vapor burns more complete than gasoline fog created by ultrasonic fogger. This means that some king of gasoline bubbler should be more effective than this fogger setup and it would not eat up additional power (this fogger consumes about 35w). So geet systems seems to be a better way to go.
Thanks,

Hi Jetijs,

Really cool fogger set up! I'm pretty sure that both cases are very oxygen deprived. If you entrained that fog in a venturi fed by air you'd get what you should ...a blow torch.

Nice experiment, yes just by blowing air through a pool of gasoline would give a better lean combustion. While the fogger gives a course droplets of fuel.

I did a quick experiment a while ago with a small fuel filler for model RC, it has some fuel inside. Squeezing the bottle a few times and letting the vapour into a small engine was enough to explode and push the piston down.

So I didnt think fogger make a good fuel vapouriser.

Excellent test and video demo Jetijs

I agree with you , an ultrasonic fogger is not a very efficient way to create the fuel vapors, we can do it many other ways.

Here is a recent topic at Overunity Forum of one way it can be done: Fuel Vapour System - Got it working!!

You should be able to use your container and modify it. Before you do you should test with Diesel and record the results for comparing.

Thanks for sharing

ADDED: That blue flame is an excellent sign of a complete burn

Luc what we need next is a diesel vapouriser to run a regular engine + plasma, a non geet perhaps

[Jetijs]

Thank you for that link Luc
I was just thinking of much the same design
Will make it shortly and see if I can increase the fuel economy to some point using this system instead of a carby.

Another quick way is to use automotive Flat air filters if you can find a size that fits in your tank. Have the filters standing on there sides with only a little fuel on the bottom so they absorb the fuel. This will create a large surface area for the fuel to turn to vapor.

[Jetijs]

Luc, can you give me a link or a picture of these air filters? I don't quite understand how they look like
