Home made HV Capacitor-ignition coil intensifier

[BarbischLukas95]

If you want to have much more capacity, laminate the Aluminiumfoil. I used 5 layers and the sparks were very loud.

[m3sca1]

@BarbischLukas95 good idea thanx for your input!

[lol9392]

what would happen if you would connect a battery to 3 ignition coils and then connect it to a 1f capacitor?

[ubuntupokemoninc]

I think your die electric is too thick

[Marcinenwu]

please send me name of music mr. electric

[rroge5]

awesome capacitor, it would be interesting to test what voltage it can store.

ohbtw the insulation on my igniton coil is broken due to to not having a suitable spark gap for long durations (alot of short durations). i tried to hot glue it and i used 2 sticks but its still sparking through. :\ guess its offf to the wreckers for another ignition coil.

[m3sca1]

is it breaking down at the top or inside the coil?

you can use lanolin oil -inox make a good one-called lanox

find it at repco.

its good for up to 70kV and just spray it on the top of the old plastic and let it soak in

[rroge5]

@m3sca1 At the Top.i shall look at it for my next ignition coil. this one is buggered beyond repair i recon. it might achualy have burnt through to inside by now.

[m3sca1]

@rroge5 well dont chuck the old coil out just yet cos the oil might fix it

[vid009]

Cut the background music ! ! !

Due to the thickness of the PVC it appears your capacitor isn't storing much charge judging by the spark output.

If I was you I would use 3mm thick PVC and double the capacitor stack.

[m3sca1]

thanx for your input.

[Driv3th3hiv3]

1. the PVC material is too thick for that voltage

[m3sca1]

well as proof of concept -the thickness wasnt a problem-was just using what i had available.

[Driv3th3hiv3]

I had great results from using cling wrap and aluminium foil wrapped around a PVC pipe also.

Made one hell of a spark with my ZVS Flyback

[jonnyasprin]

sounds cool

[madmike230]

u should use something thinner like glass sheets u will get way more out put that way

[dreamyear]

nice work..how many watt is this roughly

[m3sca1]

bout 10 watts i think

[prototype9000]

i tried that once and the spark made it to the bottle and shocked me

[john29302]

aouto transformer means 1 winding, one core, so bothe primary and secondary share same ground, same as variac. that means feedback loop is present on lo and hi side. some say never us aoto coil or tesla stuff

[Labash1]

Maybe you should turn on the lights. We cant see shit.

[dodoshlodo]

its aluminium... IUM!

[sparten1114]

be carfull that thing could bit ya. real bad. with a gap jump like that what do you think the potential is? 100k? how many MA?

[m3sca1]

its nowhere near as dangerous as playing with MOT's and wall current.

with the spark gap its around 40kV

mA depends on the frequency of the PWM.

it wouldnt be more than 800mA.

but yeah it bites

i have rubber tongs for attaching the alligator clip to the battery,cos it makes every wire go live.

[dodoshlodo]

At 800mA 12V u wont die, but it hurts a bit..

yeh ive noticed that the HV goes all over the circuit. even the heatsink of the PWM, even jumps back over diodes. shocks u on evey lead, even on th low voltage side.

Ive noticed it doesnt kick back when i have certain loads connected. CFLS make it kick back the most.

I think a choke after the PWM might help, but i havnt tried yet. Also a heavy duty POT (25ohm) turns that kickback into heat and isolates it into the pot. need heatsink tho

[m3sca1]

the cap is on the HV side.

worst shock scenario i had was when i hooked up the bg dome.

couldnt even touch the battery-without thick insulation

[smokyatgroups]

Your cap assy has nice low inductance as it's not wound like normal caps. Predominant effect is Xc which is what you want for fast charge/discharge cycles.

[somethingplanet]

awesome post!

check out our vids when you get the chance:)

[warcryrecords]

what is your input voltage at the coil? is it 12 volts or higher? if its higher how did you get the higher voltage?

[m3sca1]

a PWM is pulsing the DC into a square wave AC 6volt signal that goes into the igntion coils.

then the capacitor condenses the long thin blue spark into a shorter thicker white spark.

[dodoshlodo]

where is your cap in the circuit? on the 6v side or th HV side?

[warcryrecords]

Hello m3sca1,I really like your work. very cutting edge stuff.can you post a complete diagram or video of this setup?where are you putting your homemade capacitor in the circuit at? where are you connecting it at?

[m3sca1]

thanx for your comment.

the cap is across the output of the 2 igntition coils.

conected between the high voltage output terminals.

i plan to make smaller caps-1 for each lead,after the distributor.

so that each plug has its own cap.

[douglundy]

am I wrong? the spark circuit does not go through the points because this is the primary, not the secondary which carries the high voltage. YOure boosting the high tension secondary circuit, correct. Not the primary circuit which goes through either the points or electronic breaker system ..The super spark would only go through the rotor and back out again to the plug wires, placed in the coil output line to distributor.

[m3sca1]

you want to boost it after the distributor rotor-on the lead, if you boost it before the distibutor it will make trouble for the timing.

[prototype9000]

are you using cutting boards as the dialectric

[m3sca1]

no-i think its a polycarbonate-i got it at a recycler co-op.

chopping board would probably work tho

[crob227]

could you use the cap for a 15kv nst??

[m3sca1]

yes

[m3sca1]

no probs!

thanx for commentin'

[ipctec]

The new energy Revolution has started !

No more patents, open scource must rule the game....

The fossil fuel will come to the ends, cause our alternative energy revolution is growing wordwide !

[m3sca1]

what he said ^

;)

[XRRep]

wow that looks like a fire storm plug at the end of the vid

[m3sca1]

yeah-and its just a standard champion plug with no resistor and the arc tip removed,and ground smooth with a dremel tool.=]

[XRRep]

i think just putting a MSD ignition box on the Vehical gives 3 quick pulses of 5 amps and one 10 amp spark above 3000 rpm, that does give better fuel consumption

[potroastmaster]

at what voltage were you getting towards the end of the video? at the spark tip?

[m3sca1]

havent measured it

[shamansays]

What could someone apply this to in a real life situation?

[m3sca1]

if i can get the size down-im thinking 1 capacitor per cylinder,unless the rotary distributor can handle that sort of spark,then only one is needed.

any engine running spark plugs would benefit from a stronger spark for ignition.

thanx for your comment

[FBRK8R]

Interesting, seems to work well. I normally use wine bottles filled with salt water

[m3sca1]

yeah ive used glass,it tends to break down.

the salt water bottle caps are very good though.

cheap and easily adjustable.

[ehnriko]

COOL!!!

By the way, What about durability? Will the spark plugs last longer with this intensified set up?

Great Job!

[m3sca1]

good question-the short answer is

i dont know!

[ehnriko]

What about making a smaller version - one for each ignition cable...  we can do away with expensive Racing ignition system if this will work... I'd like to try it on the purple bug for racing.m :-D

[m3sca1]

thanx for your comment-i was thinking the same thought last night.

i will try making them smaller,so there is like you say-one for each plug.

i want to try making the cap with a flexible material that can be rolled up and put in a can.

[ehnriko]

That would be great!...

I remember back in the eighties, there was one unbranded item in the local market which VW race buffs were buying, it's no bigger than a coil and they simply attach it between the coil and the distributor... it seems to increase the spark plug power too. But I am a bit skeptical about what it does to the contact point. It's ok to intensify the spark plugs right where its' needed... but intensifying the contact point - I believe is not necessary. More Power!

[m3sca1]

yes i agree-not sure how an intensified spark would go thru a distributor.

[m3sca1]

ozicell sent me a link to a product that is an ignition wire with a flexible capacitor in the lead.

see Nology wires.

same sort of spark,and not going thru the distributor.

it looks easy to replicate too

[d3adp001]

now thats spark

[m3sca1]

an unquenchable spark!

[TomCjr]

Looks like your getting a good arc,

but didn't see any electrolysis action from your spray.

Water droplets are probably too large.

and also you're spraying into an unconfined space.

Try using an atomizer from a perfume bottle

to create a finer mist, and a small coffee can to simulate the enclosure of a piston cylinder.

TC

[m3sca1]

yes-there are no diodes-so no electrolysis.

i sprayed it with water because somebody would have ask me to.

and i was intrigued by the fact the it could not be fouled by adding water.

i soaked the plug at the end and the spark just came straight back.

[crob227]

good info.
