Greg,

Will you have to offset the sensors 45 degs for a 4 cylinder ? (30 for a 6)

plasma cdi hall effect control

Hi everyone,

I've completed the design and testing of a twin Hall effect control for the CDI system I've built. The diagram shows looking down into the distributor with cap and rotor removed. It's somewhat pictorial. One hall effect sensor is for the charge pulse and the other is for the discharge pulse. The 2.2k ohm resistors play a dual role. First, each acts as a pull-up resistor. When one of the magnets (little squares on the rotor) passes by the sensor, the 'minus' wire from the sensor goes to high impedance and the 2.2k resistor yanks the 'plus' side of the Mosfet opto up and turning the Mosfet "on". When the window has passed, the sensor yanks it to ground and the Mosfet is turned "off" again. The other purpose of the 2.2k resistor is as a current limiter for the Mosfet's opto. circuitry.

This can also be accomplished with just one sensor but would require a "break before make" inverted signal for the opposite circuit. It's easier to add a sensor and resistor than it is to design, build and troubleshoot a circuit ... for me anyway.

Peace,

Greg

Hi Timm
This is the exact circuit that is used in that video:

Peter, you were right. The problem is not in the frequency.
It turned out that the problem is in too large capacitance of the booster side cap. At first I was using a voltage quadrupler with four 100uF 450V caps. I could go up to 1000V on the booster side, but the if the discharge frequency was set to 25Hz (the minimum that I need), then there was an ordinary spark on every discharge, but the intensified spark appeared only on every fourth or fifth discharge. I could ho up with the frequency till 100Hz, but the intensified spark appeared only some 4-5 times a second. So I decreased the booster side capacity. I replaced the quadrupler with a bridge rectifier that charges up a 0.82uF 1000V cap through a light bulb. When I turned the variac to full voltage, there was about 300V in the cap. I turned the primary side ON at 100Hz frequency and there was an intensified spark on every discharge. But the effect was rather small, so I doubled the capacity. This made a bigger plasma and was still capable to handle the 100Hz. I increased the capacitance by 0.82uF on each test and the intensified spark seemed to become brighter and louder with each test. I got the capacity up to 6.56 uF, but the spark was the same as when using only about 4uF. So that must be the right capacity. Unfortunately I have only six of those polypropylene caps so I can not make a voltage doubler keeping the same capacity. I already tried that using two 2.46uF caps for the doubler, each made out of three 0.82uF caps in parallel, the spark was almost the same, maybe a little brighter. So I guess that if I increased the voltage keeping the same capacity, I could get bigger blasts. Also I noticed that the bigger capacity on the booster side, the greater also the power consumption from the variac. At capacitance of 6.56 uF, the power consumption from the variac was about 35W. Also, the more power we feed into the spark from the LV side, the hotter the spark plug electrodes become.
Here is a small video with the intensified spark about 50Hz:

Now I need to get some more caps and try the same capacity with a voltage doubler.
Thanks,
Jetijs

Jetijs,

Your video was amazing !! Great Work !!
Which circuit is this ? I know you've posted several.....

Congratulations on your continuing advancements.

Hi everyone,

I started a new topic and ask if you can please have a look: http://www.energeticforum.com/renewa...y-charger.html

Technically the same amount of energy should be released at ever frequency right? There should be indeed a reason the big bang is lost at higher frequencies. Maybe it's due to the ammount of diodes. The higher the frequencie the less time they have to recover (this is pure speculation). So a possible solution could be adding more diodes?

Right, as long as I do not go past 50Hz, there should be more than enough time for the caps to fully charge. I am not sure about the diodes, I don't think that 50Hz is high enough for these diodes to stress them. I am using 1N5408 diodes for this setup.

goldenequity, thanks for the link, I will check that out

Capacitor size

Thanks for the update Jetijs..... glad you getting it dialed in.

I thought I would insert this link to a discussion on the Dipole and Capacitance as it has great relevance (imo) to why/what you're doing with your circuit at this moment.

(but forgive me if I'm way off on this )

Broli,
Yes I tried to spray water on that 50Hz frequency intensified spark, but I could not hear or see any difference. But if I decreased the frequency to 5-10Hz, there was a bigger bang, when the water was sprayed on. This is interesting

[broli]

Nice important test data you share there Jetijs . What happens if you spray water on that btw?

Btw has anyone tried to use their own wound coils instead of the ignition coil to see what different kind of ratio windings do to the entire system.

Hi everyone
just posting what happened with HHO and water spark, The setup is a 6 hp engine with no waste spark, timing about 5 deg ATDC being spun at about 750 rpm feed 1ltr per minute HHO and water mist, nexus circuit run off engines points (runs well on gas with increase of rpm when spark is turned on) but it did not fire at all . any suggestions would be welcome

May be for the first time you need to run the engine in hybrid mode. Earlier, runs with just a little amount of gasoline. After that, introduce water mist and HHO to the running engine. If it runs OK, let it go on HHO and water injection. That's inspire us to follow yours.

Double check whether all your components and connections are still in tact. That's all I can suggest.

plasma CDI progress

Hi all,

I'd just like to post my progress. I have sent away for some very slick magnetic switches that are meant for VW ignition conversion. The kit has a rotor with some magnets on it and and this switch. I'll need one rotor and two of these switches to form a SPDT switch in the distributor housing. For now I'm making the stock distributor do this. The photos below show the stock distributor/points and some modified ignition parts. The modified one is not finished but I'll explain my plans. I posted both stock and modified for comparison.

The stock points breaker arm (riding on the cam lobes) will be the common pole of the SPDT switch. Each of the phenolic blocks will have a springy phosphor-bronze leaf contact and each with separate wires leading out of the housing ... including the common wire ... no condenser. So the common will contact one leaf contact or the other ... not both. Timing and vacuum advance stay intact. That's it for what it takes to run the Plasma CDI design I'm building.

Peace,

Greg
