Ignition Secrets by Aaron Murakami - *** NEW RELEASE ***

[kEhYo77]

Maybe the the string of diodes is to short for the potential induced at the HV output which is causing a reverse breakdown, hence no spark.
I am not too sure how it works, honestly, yet! But I'll be experimenting with that pretty soon. There is a difference between using a single HV diode and a string of series connected ones.
Maybe the p-n junction capacitance has something to do with it... Hmm. Try to add a few more diodes OR/AND a 30kV capacitor parallel to the string and see if it helps...

Just a thought...

@Aaron: Could you tell us what is the symbol for the diode used in yours/Lindeman's presentation?

@keyhoo77:
Thanks for your input!! I'll have another crack at it tomorrow. I'll add more diodes and I'll see what happens... I just thought 20 in a string was enough?
The MSD coil HV output is 43,000 volts by the way.
Gonna put a 30kV cap in parallel too...hmmm..I thought there was enough with the cap/caps in the CDI box?

[kEhYo77]

Aaron's 'Ignition Secrets' shows a benefit of using HV "Peaking Capacitor" (0,001uF@30kV) in the same place as the latter diode, which is a common practice to enhance the spark.
Now, this diode might have a significant p-n junction capacitance and when fired, this capacitance is being charged up, delaying a bit the spark, but producing a stronger effect. I think i depends on the energy unit delivered to the HV output. Try charging this cap(or series of caps) with a single pulse through your diode string in series and measure/safely with some MOhm voltage divider the charge accumulated in the cap. This will be your HV threshold for the diode to block.

Now as I said I am not sure whether the purpose for the diode is to provide a freewheeling effect or the breakdown avalanche gain so yo have to experiment. Take caution!!!

Please don't use a peaking cap if you're trying to do the plasma. The cap will suck up too much and will negate the effect.

20 should be enough - I used a 20-25kv string of diodes with my Mallory Promaster, which is 70-80kv by itself and even more when I discharge a cap into it.

Thanks Aaron,

I have learned heaps so far. That's enough info for me to finish.

Saw your pic - looks just like mine! lol

A normal 12v ignition coil is fine. You don't need a high performance one.

Depending on the coil's polarity - that tells you which way to place the diode.

I used a Street Fire MSD (MSD's budget model) - works fine. The cap is between 2~4 uf... just use small ones - that is all you need.

Any non resistor plug is fine. You may see a couple hundred ohms which is still a lot but much better than 5k+.

You mean an opto timing switch for ignition? If so, then no, you don't need the timer. The timer is for bench testing and I use one on my jet engine since there is no timing. Normally, you can shut off the ignitor on a jet after it is hot enough, but I leave the plasma blasting nonstop.

Hi again, this is what I came up with Plasma Ignition

[sciencisto]

how is it working

I jak to działa?

[adurer]

Aaron, is it possible to use only 4 HV diodes for a 4-stroke, 4 cylinder engine car ignition? I mean one single HV diode per spark plug. Does it exist such a reliable diode on the market?

hv diodes

I recommended the 6A100 because they've been bulletproof so far it's very inexpensive to make HV strings out of them.

There are some single diodes rated correctly that can be used instead of making strings. Physically, they're not that big either, cost a bit more but can make the job easier. However, I want ones that are seriously overrated so I don't have to worry about anything.

I'll post here Plasma Ignition | Plasma Jet Ignition about some single ones that I'm going to be testing.

[adurer]

I'll post here http://www.energyscienceforum.com/internal-combustion-engines/689-plasma-ignition-|-plasma-jet-ignition.html about some single ones that I'm going to be testing.

Looking forward to read about that.
Those 30kV 2A High Voltage Diodes look beefy, but not clear how big they are.

Plasma Ignition Book Concern

Dear readers, Mr. Murakami and Dr. Lindemann,

In order to clarify the purpose of the Ignition Secrets book, I pose the following question.

Does this information package contain instructions for modifying a generator electrical system,
or is its purpose instead for production of the plasma effect?

Thank you for sharing visuals of the demo unit.

The vapor fuel venturi adapter inlet to the gasoline generator is responsible for causing governor oscillation and poor generator performance; a question arises in its place, would a flexible tube secured into the air cleaner housing with a 1/4npt fitting and wire strap to hold it in place directly in front of the carburetor intake offer suitable performance?

The propane regulator goes to the needle valve connecting to the engine regulator.
The output of the engine regulator then normally travels to the venturi adapter positioned between the air cleaner housing and carburetor.

I'm certain this plasma technology will work to improve its performance with gasoline, and hopefully in the future when a working solution is found to the vapor fuel supply system, although without instructions for integrating it with the electrical system I would have to request a return.

Otherwise it would please me greatly to contribute.

About 6" long.

That thumbnail you post does not open up.

It is difficult to get gains in a gas generator if you have the normal main jet inside the venturi body because as long as air is blowing over it, it will continue to use the same amount of fuel no matter what.

You can replace the jet with high-altitude jets that will let the engine run leaner. But you have to compensate for that so it doesn't damage the engine. Plasma and water injection can do this. You can get an ultrasonic fogger and submerge it in water and put a tube from the water container's opening to the carburetor to suck in that moisture. The engine will NOT overheat with the high-altitude jets and you will get extended running times.

The fogger can also turn gasoline into vapor, but that is at your own risk because it can blow up in your face.

[zolgar]

When the vapor fuel supply is through the gasoline hose normally connected to the tank, it should then be allowed a proper mixture of fuel and air without the engine regulator, instead relying on a precision needle valve... why not?

gas generator

That pic looks fairly self explanatory.

I put a ABS 4" diameter end cap against the 2 bolts on the generator end cover. I also replaced the rod with threaded stock. The small timing wheel is attached to the stock and it has 1 small neo magnet on it.

Inside of the end cap is a 4" diameter slice of ABS pipe that can turn inside the end cap. A reed relay is glued to the inside of that pipe and is connected to a transistor.

Therefore, I can turn the pipe inside of the endcap to have an infinitely adjustable timing system to trigger the MSD.

I don't know about the needle valve, there are no needle valves in the typical generator carb. It is simply a wide open jet of a certain diameter - it is not adjustable.
