    That is exactly how my circuit works. Which is the whole beauty of this thing, you can leave your existing ignition in-place.

    The only info on the plasma that I'll share will be posted in this thread from now on. And that will include updates, etc...

    There really hasn't been much evolution of it since the package - it is just taking that info and applying it - to the jet or generator. I'm using the exact setup myself on both applications that I discussed in the package because I can confirm it does what it is supposed to do. So, hopefully everyone is happy to know that I'm actually using what I recommend. lol

    Thanks for sharing your experiments. I have used a secondary spark gap on bench tests but backed off from it
    because if we have plasma too big in the engine, it can damage it. When the plasma is under compression with a lot of air, it grows even bigger.

    With plasma that big in your engine, would be interested in seeing the inside after a few hundred hours of running time.

    And that HyFire Mallory system works fine for you?

    Thanks Dog-One

    I'll check that out.

    What about a DC voltage multiplier?
    I have heard that mosfets can be set up in a ladder arrangement to do this, eliminating transformers, variac's, mains, inverters, and all manner of stuff

    Before this idea I was thinking of a more portable set up using a step-up transformer and a 555 timer to drive it.

    Yes, you should use less duty cycle on time and use the 555 in the monostable wich give you an adjustable output that does not depend (in terms of "on time" ) in the input for this monostable configuration. this way you can adjust the exact time (not to much on time that can overheat the output transistor and no little on time that can avoid a spark in the secondary of the ignition coil or transformer) that the primary of the coil needs for any speed in the motor. do you know what I mean. sorry. My english is so poor. I am Mexicanˇ

    QUOTE=hh1341;6440]Here are my questions........


    My mosfet gets hot quite quickly.( Nte 2376 )
    I am using a 50/50 duty cycle on my 555 .( maybe the cause )

    I seem to be drawing about 4amps, to a standard auto coil with 12 volts. Does that sound about right

    Also I was wondering if you could explain the function of the several diodes in your 555 circuit and the very short off cycle.

    Yours

    That is the same concept that is in all the early patents - using a secondary power supply to charge a cap and that is across the plugs.

    The advantage of my system with using the cap inside a CDI/MSD is that some people have problems getting the cap to follow with a lower voltage stock ignition coil.

    So with the CDI, you get a higher voltage that stands up to more compression especially on performance engines and the cap simultaneously doubles as the low voltage source. It also means that with the CDI output of the HV being higher, an even small capacitance cap can follow, which is desirable to keep the size of the plasma down. And with the CDI discharge, you can open the gap of the plug even bigger.

    Arron......are you going to put that Jet in something, and fly it ?

    A couple of things here. Without the secondary gap (that would be there if you have a distributor), the charging caps dump across the ignition coil because they have a path through the diodes and through ground to do so.

    The plasma is controllable by two methods: (1) size of caps (2) setting on the triac current limiter. My goal was to have the plasma roll off when approaching max engine speed. Larger caps charge slower which allows me to set this roll off point.

    The plasma size is somewhat arbitrary at this point and will be adjusted once I make my attempt at igniting water mist. My hope is to use minimal Brown's gas maybe even to the point of none and will use the plasma energy and ignition timing to find the sweet spot. So what was needed is something with more than enough power and tune it down to match the engine conditions/behavior. If a small HHO cell is all that is necessary, we are in fat city; even better if it is only needed to start the engine.

    Yes the Mallory system works fine, this way. I tried using it initially with your Ignition Secrets basic setup and it worked somewhat. Pretty small plasma. It ran for a day or two then blew out the internal IGBT which I replaced. While inside I noticed the charge cap was only 1uF which seems way too small for my intended purposes. I wanted a visually appealing plasma spark, knowing full-well that it would likely need to be tuned down for any long duration use.
