Water Sparkplug

Caps

If I may be so bold as to make a suggestion, I see a lot of low bandpass filtering what what about the high end. Have you considered using a simple and cheap varistor across the output?

edit - So across the the two black wires on your multiplier board. Then you can use cheap ceramic disk caps that won't rob so much power from the circuit.

If the 'cheap' caps are ceramic then they are low capacity. The oscillator would need to run at a very high frequency to keep up with the power demand from the water spark plug circuit. My present combo of CDI Cap and frequency is actually about 36 Watts at the hi freq (high RPM) end of things. A dinky cap circuit would not be able to provide that power throughput at the oscillator's low freq. I'd normally agree with you but this is a 'power' circuit not an audio circuit.

Peace,

Greg

Da... I got two lines confused when I edited. I meant to say the varistor across the two black wires going to your multiplier.

The disk caps were just an after thought after I built a circuit for this last summer and used disposable camera flash caps and got bit a few times. That board could kill an old guy me quite easily.

But hey, if it ain't broke don't fix it. Nice prototype.

@everyone,

We had a new member among us that went beyond any acceptable posting norms in another topic, however the Administration of the Forum has stepped in and took care of the situation and cleaned up the topic.

Thank you Admin for taking care of this mater.

Let us continue to work together on this important research

Thank you all for your time and sharing.

Hi Luc,

Looked like things were getting a little hijacked there ... very frustrating ... wasted time and energy.

I'm close to putting water to the test. Got the technical issues solved ... me very happy !.

Peace,

Excellent news Greg

This come at the right time my friend as we can all use a shot in the arm to get us going again.

May the force be with you as we can only follow your lead

[ashtweth]

Dam i miss all the fun , i am still recovering from Greg's prior shots in the arm 3 more days to go to see if the lower cap value on Rev's has done any thing to our plugs.

Hey Guys,

I'll go ahead and confirm again the LOW plug wear, I use less than 3uF and have had NO PLUG DAMAGE to this point. Same plugs in bench tests setup for at least two months now. Higher voltage with lower capacitence ROCKS!

@Greg

I got the new circuit built, all except the transformer which is supposed to arrive ANY DAY NOW. Next thing we need to invent is a way to have our parts e-mailed to us!!! Below is a pic of the board, awaiting the transformer, and the heat sinks are not on the transistors yet. I am also going to use computer fans in both ends of the project box to make it a wind tunnel.

Hi Mike,

Great news! And yes, I now have a high support voltage multiplier that stays between 450 VDC and 385 VDC across the full spectrum from 0-RPM to 4000-RPM (4-cylinder) so I'm also using only 3 uF now and it's a 'crackling' spark. HV and LC ROCKS ! ! ! And of course this allows us to eleiminate the Storage Cap because the multiplier serves the purpose ... as you have discovered.

Peace,

Greg

Air Gap

Hi all,

A member from Overunity.com pointed out the need for a diode at the HV output of the coil to prevent coil heating and partial coil voltage negation caused by the reverse voltage of the VexUs circuit. This make it much like the Tero circuit. This was a very good observation on Zis's part. This IS required for HV on the bench where you have the coil hooked up directly - full time. However, in a real application, the coil is never, ever connected to the circuit because of the air gap provided by the distributor. By placing an air gap at the HV output of the coil, this can be simulated on the bench. The spark is greatly enhanced. For coil packs you'll need an actual air gap or diode. I prefer the air gap because I don't want ANY resistance in this path. You need to shield the zone against RF leakage though.

Picture below:

Dear researchers.

I start worried about one thing. All what I see- in last times is very close to STANDARD CDI IGNITION CIRCUIT Here is the schematic. If you look at circuit you’ll see auto generator with secondary voltage about 400V then bridge rectifier and than T112-16-10 and then after C2 is output to ignition coil. Only difference is- this 400V impulse is going in to the primary of ignition coil. Dear friends! Please make Your MPG tests! If there is NO GAIN, then your job goes to nonsense.
Thank, You!

The circuit you posted is a typical CDI circuit, the one from gregs can be called a TCI (with no transistor if you like it that way ) with a HV supply added to create the plasma effect, if that make sense.

@ Ansis

I am a mechanic, by trade, and have seen the CDI systems for sale by the various manufacturers of them. Many that have experience with these CDI systems will tell you, they are junk! They fail on a regular basis, are expensive to purchase and have installed..........and BTW, their spark is NOTHING like ours, I can tell you this first hand! They use a multi-spark that only works to a certain rpm. If we have enough energy, as we do, we only need one spark. My V-8 circuit will run stable at 5,800 rpm, for a fact. Anyway, there's my two cents worth..............................Mike

any chance of a circuit diagram and parts list that us electronics illiterate guys can work from (greg)
