Electrical igniter for gas engines A keystone to understanding by Magluvin

Thanks Delboy, makes sense.

Question,  is there a minimum charge voltage recommended for discharge? As in, can this be accomplished discharging 500v vs 50,000v.

Trying to stay small here.  =]

Thanks again

Hmmm, to have enough V/m (volts per meter) you have to have high voltage and high frequency. How high? Well read Teslas recommendations for bulb, for example, in his patent 454622 he says lowest practicable limits are 15kHz and 20kV.
That is of course on secondary, but if you asked on primary than approx. it should be divided by Q factor of secondary For example 20kV / 200 = 100 Volts

Now I can agree with you.Except it needs pure unidirectional energy transfer and the physical meaning was found lately ! It is 100% efficient energy transfer without BEMF based on quantum transition from primary to secondary.

Hey Delboy

Lets say the primary is a few turns, If we discharge 100v into it, what amount of turns are we looking for on the sec. ? And should it be of the traditional Tesla coil look and type, or are we looking at a Kapanadze style?  Spacing between windings?
Bifilar?  Is there any need for bifi here?  =]

I saw a vid yesterday that a guy had a setup like a Tesla coil laying horizontally, and the output was maybe developing a 1/8 inch spark but continuous, then he applied 1 single primary wire from a step down transformer, and a light bulb lit very bright on the secondary of the step down transformer. The secondary was only 4 turns of some heavy speaker wire on what looked to be a ferrite core.  The primary looked like many turns of fine wire of witch only 1 end was used to make connection with the driver Tesla coil.    Does this qualify as a good connection between the 2?  Or as per the pics above, use caps in series to connect both wires?


Thanks Delboy.  You have been a big help.  ;]

Here is the vid.     I tried the neon transformer on a large 110v to 12v transformer.  1 wire nada. Both wires nada . 1 wire and a spark gap on the other, nada.  But, 2 560pf 1kv caps in series, with 1 wire and direct with the other wire, we have light.  Not as bright as 12v would do, but it lit.   I know this is just a very rough way to try it, but I found what worked and didnt, for what I had at the time.
Also the primary of the transformer is high ohms.  But I was surprised that the neon about 2kv at 45khz actually affected the transformer as good as it did, considering it is designed more toward 60hz.

Wound a large inductor with 23awg wire for igniter circuit.   Will give it a go tomorrow
