Hi people,

Has any one taken trials with spark under pressure and see what hapens?

Capacitor70

Because of my results with the coil arrangement I will go back to the diode setup.

Can you please help me understand how did you go for the 6a10 diodes?

6Amps why? How can the diodes stand the discharge of the capacitor since it is a short when the gap is pulsed with HV? The current here is theoretically infinite right?

Now the voltage blocking.
You say 19x 6a4 which gives a 7600V blocking or 12x  6a10 which gives 12000V blocking voltage.
Why did you go for this values?
I don't know what is my coil output voltage but I've read that 40000V is normal.

I'm asking you this not because it doesn't work. It DOES WORK! But I need to find the cheapest diode arrangement to continue the tests, and without this data I'm a bit tied up.

Why ? What are coil results ?

Diode have 400Amps Transient current capacity for 8.3mSec

increase number of diodes until see spark on the tip of spark plug
I don't know what is my coil output voltage but I've read that 40000V is normal.
Yes it is 40000Kv, but 3000 to 6000V is enough to generate spark at the tip

There is no cheapest diode arrangement, Diodes get very hot NOT SUITABLE FOR LONGER  TEST TIMES, Don't go for diodes, coil solves all problems

@rfsimoes:
I too started with the diode setup and got great results, but my diodes got so hot that the solder melted and the diodes fell apart! The same thing happened to Cap70.

@everyone:
I will be testing Cap70's coil setup in a B&S 14hp engine tonight!!! PLEASE cross your fingers for me  ;D ;D

Hello all, I'm Remoi from waterfuel1978 group.

@xbox
I cross fingers for you, you are a nice man, you share all your test and the last one with the sparkplug under water is just wonderful. I hope you will start the engine tonight on water  ;)

@capacitor70
I was so close to your diode setup instead that my lub was after the bridge and was 100w. That was my biggest mistake. But as I don't have any knowledge in electronic, I never tried without the lamp. I surely started the engine 2 years ago if I knew that the lamp limits the power of my setup to 100w.

Now the car we was testing on is sold. I just get a lawnmower running perfectly on gas. Tomorrow I will try again my diode setup on it (I tried today but the sparkplug is resistive  >:( I need non resistive one). if I get results, I then will go for your coil system.

You talk about 1100pf and 6000v. So i can use 3x 3.3nf@2000v in serie ?
Also can you explain me/us more about your core ? what size, what material ? The green wire, is it just a simple insulated wire we can find anywhere or something else ?

What do you think about the 330?f capacitor (I use 470) ? Will it survive on a long time engine run at high RPM ?

Thank you also for your tests and sharing it.

Best regards

Remoi
