My s1r9a9m9 replication!

Hey guys, I think I just found something.......   

Check this out: http://www.steamengine.com.au/ic/history/spark-intensifier/ 

So, can this thing help to produce better plasma?? 

Hopes this helps....     


ps: I had read some websites, they says that Pulsar plugs are using this technology.... Please verify...

I really hope that this new circuit works because now I noticed that I blew UP 17 of 19 BY229 (1,5Euro)diodes.
28,5â,¬  shorted
I thinks It was due to using a   800uF  cap.

My HV coil was giving me no spark also so I think that cap also did some damage to HV coil.

Full bridge rectifier still ok, but this reminds me of recheck the two 1n4007 at the output of HV coil...

Tomorrow I will get  some toroid coils and polyester caps. these will bee free recycled items so it's far more cheap than those exotic diodes.

Well,
I have updated my upper circuit:

We need to have a big di/dt current change and so a
big induction voltage what we are interested in the
toroidal secondary coil to fire the sparkplug.

We need to prevent the transistor to be killed...

So either use a transistor or MOSFET which can stand at least 1000 Volts
and put a capacitor in parallel with the coil
or use a neon bulb in parallel with the transistor to
reduce the spike voltage at the transistor to around 90 Volts.

The best thing would be, if you use the contact points of your ignition
system in your engine to switch it, if you still have mechanical
contact points.

I will draw up another diagram.

Hi,
for experimenting you can try first with this simple circuit.

It might be better, if you place about 1 nF cap (2000 Volts rating) still across the
green coil, so you get a better burst and thus better sparking at the sparkplug.

Play with the winding ratios.
The highest voltage on the red coil will be produced, if you switch off the
current in the green coil,
so be sure to have the polarities of the coils right, so when the
current in the green coil is switched off,
the induction voltage in the red coil must have the polarity to
add up on the 330 uF cap voltage and NOT to oppose it.

Hope this helps.
Regards, Stefan.
