    Thumbs up Plasma Ignition | Plasma Jet Ignition

    I'm starting this thread to talk about Plasma Ignition.

    I have Ignition Secrets by Aaron Murakami | Plasma Ignition available and it doesn't include technical support for people's experiments. I do however, help quite a few people out anyway, but from now on I'm only going to address any of that in this thread. So if anyone has questions, they have to read this entire thread first and then if the questions aren't answered, I can try to help out.

    The concept is simple - high voltage from coil jumps the gap and ionizes the gap and makes it conductive enough so that a lower voltage capacitor in parallel with the gap can discharge over the gap creating the plasma impulse.

    I'll post more later, but this is just to get things started.

    Answering these questions for all to see is a great idea......Thanks

    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

    Hi Carl,

    Thanks for bringing these questions here!

    I'd put the mosfet on a heat sink if you are having heat problems.

    Also, if this is just for a bench test, I'd reduce the duty cycle to the lowest possible to still get the effect.
    You can replace that 1k resistor with a variable one to adjust the on time. It will automatically change the off time.

    Are you using an off the shelf CDI or did you make your own cap charger? 48 watts being high or low would depend on that.

    The diodes on the 555, I really don't know. I used that 555 circuit for a long time for various projects because I can change the on and off times for serious pwm control.

    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

    Thanks Arron,

    I may have not read all the info on the forum or missed a bit.

    This is what I was looking for........

    I think the setup to be applicable in a working application would need to have the cap switching done, solid state, and the voltage supplying the cap to be raised from available 12 volt to 120 by, say, a doubler array.
    One could use a step-up transformer, driven by a 555, but it's always good to keep the parts count down.

    What work has been done in this direction, who is doing it, can I join them?
    I need to get this on the road.

    Yours
    Carl

    Hi Aaron,
    thanks for getting this started. Just to be sure, this is what we are talking about right?



    I am very interested in how you are supplying the higher voltage at a steady rate on the vehicle itself. I was thinking of using a small 300W inverter. I am more interested in knowing what you have used that actually works.
    Thank you for sharing this mod.

    Aaron, you ststed in the above that your plasma ignition works on modern cars. I assume that you mean cars that don't have the regular ignition coil that you use in the video.
    I have your book Ignition Secrets and as best I can tell only the old style coil is used. I would like very much to be able to use thePlasma Ignition on my car, but I am lost because I have no coil to work with, other than the one inside the distributor. My car is a 1997 Acura CL 3L V6.
    I will be unable to use the plasma ignition until I get some more information. I hope someone will be willing to tell me how to go about using this technology. And a parts list would be most helpful.
    I may also have some helpful information that would allow water to be more useable as a fuel. I have never seen this
    information mentioned anywhere. Thank you for your help. UseNoFuel

    I'm not familiar with the ignition in your car. I did have it hooked up to my 1998 Subaru Legacy GT with a wasted spark ignition coil pack - did a whole presentation on it.

    Can you post some pictures and diagrams of your ignition?

    Aaron, I made a mistake in the above post when I said that my 1997 Acura had no coil. It DOES have a coilo and I removed it so I could examine it. It is nothing like I was looking for! The coil has a plug going into it from the wiring harness. The plug carries THREE wires. and, of course, there is a HV wire going to the distributor.
    I looked up coild for this car in the online parts catalog and I see that they offer similar, of not exact, replicas of my coil PLUS regular canister coils which are all 12 volt and all are replacement coils.
    That leaves me to wonder WHY my coil has leads going into it. I suspect that one lead goes back to the Control Module or to the ECU. I do have a new 12 volt canister coil that I could use if I knew how to wire it to the existing 3 wires.
    I am an old time mechanic and I know little about cars since they started using ECU's.
    I know I will need a CDI and HV diode(s). Can you please tell me how to procede ?
    I am sure this is all very simple to you, but not so much for me. Thanks again. UseNoFuel
