Electrical igniter for gas engines A keystone to understanding by Magluvin

The magic happen in primary.I've always said that if we know exact Smith circuit at primary including neon sign transformer we will find the solution.
But first please help me find what happen in case of Tesla igniter patent.
If capacitor is discharging into low induction coil in the same time high self-induction coil is accumulating energy in magnetic field. That coil is connected between positive of battery and capacitor terminal (exactly what Tito mentioned in one of his tips)
What is going on when there is a break between capacitor and low self-induction coil ? Capacitor and high-selfinduction coil form series resonant circuit IMHO.

1. Is the current from coil now in the same direction as previously ? Charging capacitor terminal connected to that coil ?
2. How fast does it happen ? Can we compute it ? Is that related to series resonant circuit energy flow ?

In all LC circuit tutorials it's started witch charged capacitor, how is energy bounced between coil and capacitor IF the coil is "charged" first ?


Help me find the correct equations so we will not blindly replicate other's circuits.
I bet all equations are quite simple and known.What  we have to know :

1. How long lasts capacitor discharge into low selfinduction coil ? I mean HF oscillations
2. How long capacitor must be shorted to low self-induction coil to get enough magnetic field in high self-induction coil to recharge cap later ?
3. How long capacitor and high self-induction coil must form series LC circuit to allow all energy of coil dump into cap and PREVENT OSCILLATIONS (which would flow energy back into coil)
4. What should be the induction of high selfinduction coil to limit charge of capacitor from battery ? We do not need electrons here. Capacitor should be charged by pure potential from coil back EMF I think.

Hi everyone,
been a lurker here for the last 2 months reading lots of topics.
while I was looking for Tesla information I came across this web site
http://www.tesla.hu/tesla/tesla.htm
Colorado Springs Notes are posted here also.
I hope to join in the research soon.
Now back to your regular programming.

Forest,

I think its quite the same thing to start resonance witha charged coil or a charged capacitor. Actually they charge/discharge each other as the frequency of the circuit.

Considering the ozone patent, i think the charging cap part is quite straightforward. Charge a coil and then discharge it to a cap. The LC ringing effect of the coil discharging to cap and vice versa is a nuisance to the ozone patent smooth operation i guess.

By assuming some high inductunce of the range 50-100 mH and capacitance of the order 20-100nf for the ozone patent, again the ringing goes to khz range.

But, IMO since a high inductunce of the charging inductor, there is a relative high q (initiating low amp currents) and since the resistance, of the charging inductor is little, there is not any great diminishing of the energy due to oscillation between iron-core charging inductor and capacitor.

Now, to become more hands on. Lets assume the commutator rotates at a rate of 3000rpm or 50 per sec and has 4 conducting/4 non conducting areas (8 totally) That means each last for 1/400 of second or 2.5 msec.
If the charging inductor is 50mH and capacitor 100nf this gives a frequency of 2250 hz/sec or 5-6 cycles per commutator time during inductor collapse to cap. i guess not appreciable energy is spent there.

And upon next conducting commutator contact the first LC (charging inductor-cap) is becoming obsolete since the new inductor offers quite a less impedance to cap thus becoming LC1 of air core primary of few turns and cap, while the cap is charged from the battery.

This is how i see the patent to work and correct me if i am wrong.
...

By the way, facts and clues point that during a discharge of a cap to a coil produces the magic and not the other way around.

@ Mag,

Any news from your tail-ing experiments? Soon i will join you

Hey Logos And Forest.
I have not gotten a chance to play, but I will have some time tonight.
I am going to take some time and do the vids on the basic igniter and Titos relay pulsed transformer and a strobe light powered transformer, just to get them up here for the history of it. Then Im going to get some tail.  =]

I find the strobe light to be an interesting drive device. Enclosed spark in the tube is quiet and quite visible.  Spots, I see spots!  lol  Depending on the load, which is inserted in between 1 of the strobe bulb power wires and the strobe tube, the flash changes in the tube. A low resistance load or low impedance, the flash is normal, but as the resistance gets higher the flash turns more into multi simultaneous thing sparks.
I have 2 different strobe tubes,  a straight 1.5 in and a curly one.  The straight tube can get qite hot fast as compared to the larger curl tube.  I suppose I will have to put a request out to Steorn as to the best way to gather that heat and send it back to the bat. ;]  lol  It seems as for very little current, there is quite a bit of heat there.

But after those lil vids, I will try the whole dog and wag a tail with the same circuits as in the vids, and we will see what we see. Its a start.  See ya this evening.  =]

Look at Tesla igniter patent.The discharge in sparkgap of secondary is powerful enough to ignite oil vapour.Not a tiny spark from HV coil.
That clearly shows there is energy transfer.

Let me ask something.What is going on if coil was first shorted with high amperage low voltage current and then one end of coil is completly disconnected from circuit and float in air. What is going on with magnetic field of coil ?
What is going on with current trapped in coils wire turns and what is going on with magnetic field trapped in core (if there is core) ?
You see coil is now like a tail, connected only in one terminal with circuit. Does its energy dissipate in air or rathe into circuit !?
