Electrical igniter for gas engines A keystone to understanding by Magluvin

Hey Forest
Are you going to try it?  =]   1st suggestion will be to fuse 1 of the battery terminals. I burned my bread board a lil bit by thinking I was good. =]
But instead of a fuse, I used a light bulb. One that takes a bit of current to light, while cold is low ohms.
Then if there is a problem, the light lights up thus increasing the ohms of the bulb and limiting the current to the project. When it lights, you know something is up. =] And you dont have to replace the bulb.
Also, Radio Shack has a bundle of various disk caps for a couple bucks. These are what got me the highest output. Again it will depend on the transformer.
I think you will enjoy the experiment.
Any Questions, Ill be around. ;]

As for the diode and resistor, a couple posts before Tito posted the drawing, he said " dont forget to use zener diode, 3v min."  I cannot say for sure that he meant that diode. And the resistor value is a guess also. i just used a silicon diode. No resistor.  I need to get some zeners to try.
One thing for sure, that cap is not there for helping to save the contacts on the relay.     So maybe the zener/resistor does that job, and maybe it does other things.
Also before the drawing he said that he had 3 coils secondary and primary.  Trifi ?  Again Tito raps in riddles.
And the riddle that gets me the most is, he claimed that the secondary is "perpendicular to the primary. Well I have tried that in 5 different ways and a regular transformer worked the best. I havnt tried the bifi or trifi yet.
Im working on busting apart a glued at the mating points, ferrite transformer core, to get a good trifi winding on the plastic former that slides on the middle post of the core. Threading a trifi will be a mess without a lot of time spent to get the turns neat. And ferrite bead cores cause the windings to be separated some on the outside and bunched up on the inside. I prefer a real transformer model for this project.

I like Tito. But back then he seemed to be all about giving it to the people, but now he has a different view I suppose. Since this drawing has been brought up here, he hasnt been around.. Where ya at Teets?  =]

well...I have already 12 different combinations of elements in circuits and still growing.... A lot of circuits to test...

I was not useful lately so I found Tito first schematic and added polarity marks 
Keep going.

Again you are missing the point! Here what are you missing:
-you don't have large input inductivity which will secure small current from source (you can use secondary of standard transformer)
-you don't have small primary indctivity which will enable :
1. large current from condenser to primary (do not use standard transformer with core, use air core transformer) and
2. high frequency 20 kHz < f < 100 kHz

and later discuss about design of secondary (spiral form, small resistance, high Q etc...)

I have read the suggested patents by Tito, namely
* 568,178, 568,179, 568,180 & 577,670, + 609,250 & 568,177

Apart from the obvious that Tesla wanted to achieve a sparkgap-less, noise free, relatively low voltage, smooth-resonators of high efficiency, the following motivate my curiosity.

I must say that all this study has been brought by Tito. Tito suggested those patents. The main difference of those patents from Tesla usual ones (apart from the smoothest resonance attained) is the utilization of High induction coils for effciently charging the discharging caps.

We all here seacrhing for free energy i guess. So according to teacher Tito, if the extra energy does not lie in the normal Tesla coil resonator of LpCp & LsCs, then it must lies in the inductive discharge into capacitors. (or else those patents have not special meaning. At least for me)

...
I proceed. In all those patents Tesla standardly uses high-self induction for storing a primary energy and then upon circuit break the inductive discharge channeled to cap(s), which in turn upon circuit resume the cap-stored energy is utilized in another coil.

Tesla used this concept by both utilizing DC primary source as well as AC.

1) Particularly in AC, he says it is of advantage to break the circuit at the top of the Voltage wave. (see pat 568,179, page 1, line 60).
I initially thought he interrupted the circuit at the top of current wave so as to store the inductor maximum energy. (since E=0.5*L*I^2) Nope he says, voltage wave. Note that top of voltage wave is not top in current wave in a curcuit containing inductunce.

2) I was stunned to read that Tesla described in Patent 568,180, page 2, line 40 that when operating in AC as a primary source is of advantage even at the peak of the wave, instead of 1 break, to have multiple makes & breaks and he used two discs one stationary and one rotating that each commutator segment was split to many individual ones. So at each AC voltage peak, many make-breaks were made.

I do not know, but according standard physics, even at the top of the Wave or at maximum EMF of the alternator, the "many makes and breaks" would not allow any considerable current to flow in the High-self inductunce coils and no particular energy could they release in return.

...
Bottom line, i got the impression that Tito wanted for me to know that using a considerable high-voltage (peak of wave) from the source, to charge a high-self inductunce for a minimum amount of time (say 1-10% of its L/R constant?) and then discharge it to a collector cap then we are to expect something unsual...

I won't argue.Are we here to argue or to help each other ? Open relay and use your imagination then help me find how to recharge capacitor from coil.Hmm..maybe Tito put wrong description in schematic and diode and resistor are here to protect capacitor from overcharging....
I trust Tito and that means capacitor discharge is not going to the transformer at all (because that's how capacitor is placed in schematic). The main problem is in relay coil - it has to be placed somewhere along relay contacts to operate as vibrator. In the same time it has to recharge capacitor when disconnected from battery (as per Tesla patent).Still to many unknowns.I wish I could know where capacitor is discharged .... does it discharge across relay contacts alone or with relay coil in series to contacts ?

Btw I have some questions about coils. Look at the picture with coil and automated switch.When switch is open coil is saturated because of large current from battery.But what happen when switch is closed ? What is going on with magnetic field in coil ?
