Spart Plug Ignition Circuit

Hello, I was just reffered to this site, and all I can say is wow, I wish I could have found this site earlier :)

I've started a new project, using a home-made jet engine from a diesel truck's turbocharger. My 2 jet engines are going to be mounted on a go-kart frame. For more information on my project, check out my website: https://www.jetkart.cjb.net

Also, for more information, check out the Yahoo Group: https://groups.yahoo.com/group/DIYGasTurbines/

This is a VERY fun project for anybody who loves fire and noise :D

To ignite my jet-engine, I need a ignition circuit. My electronics experience is very limited, and I have no experience with high energy circuits. This is basicly just one spark plug, with the coil from a car, running off a 12V motor.

I understand that this circuit is very simple, but with 10,000 Volts, I dont want to screw up. I have found a few schematics, but nothing is listing things in detail.

Finding the coil, spart plug, and spark plug wires won't be the problem, but Im not really sure about the other parts needed, and exact specifications on these parts.

If you can provide me with any information, it will be greatly appreciated.

If you check out my web-site, be sure to check out the media section.

Thanks,
Jonathan Ashley

Whoops, I meant to say 12V Battery. Sorry for any other errors.

Actually this is an easy circuit to get the spark, you need to make an AC output to the primary of an ignition coil at a frequency around a 1KHz (well actually the frequency isnt that important). The problem is the distribution, do you have a cap and rotor setup?

Opps i just read that and saw its only 1 plug... Well then it is easy, just provide a good high voltage to arc on the spark plug.

I will draw you up a circuit if you want, but you gotta put a "the12volt.com" sticker on the kart.       j/k

that thing sounds very cool. be sure to put some pictures up on the website, be sure not to touch that damn spark plug they hurt like hell

Opps i just read that and saw its only 1 plug... Well then it is easy, just provide a good high voltage to arc on the secondary of the coil.

Actually, I would be more than happy to.
Im trying to get some sponsors, for both finacials and just to have lots of stickers on it :-)

If you can give me a hi resolution image for this sites' logo, id be more than happy to put one on. I currently have two sponsors, providing finacial help, and a few others that have helped with various parts.

hah cool, im sure the admin wouldn't mind, I'll draw up a circuit tomorrow morning, im too tired to now, its a simple setup. but ill draw it up so it is easy to read and understand

Thank you very much

here ya go:

any questions, feel free to ask.

Ok, now its been awhile, but I'm taking a stab that U-1 is a time circuit? I just recognized 555, and from what I can remember, it's a time circuit... correct?

Ok, as far as the capacitors go.... what is nF... I know of uF, but what is nF... man I hate being a no0b!

the 555 is a 555 timer chip. Its just one integrated circuit.

nF is nano Farad, (10^-9) 100nF = .1uF : 10nF = .01 uF
