Lets Just burn water instead for now! Plasma Injector rework

[CompuTutor]

I just asked a person in another forum
that worked directly on the testing of
the Krupa FireStorm spark plug if he
knows of anything we can get now
over the counter that needs no kiln.

[CompuTutor]

Sadly the answer was outside of the average experimenter.

It was believed to be a zirconium based product, pre fired,
that had to be cut with diamond tooling, and was difficult.

I've seen experimenters mix powder with epoxy.

Might work for short validation experiments.



Does anyone here know of a better product
we can all (Afford to) purchase over the counter or online ?

A trade name similar to "FireBox" is stuck in my head,
but that is not quite correct according to Google.

Anyone remember the correct name for it ?

It is a two part compound,
a paste when mixed together,
and doesn't contract/expand
while it hardens or is heated.



What (Other) product,
besides cement/morter based products
do people use on small ceramic kilns and so forth?

Thank you

[Hope]

Let us all back up -  ceramic in spark plugs is there to provide a thermal path     and  did you read the part on the company lit.  that explained 240+ C  and extremely rigid ?    hey  sounds like you would like us NOT to try this,  this is not a prototype approval forum    it is a let us see what can happen and what our minds can overcome place.   Embed a ceramic tube in yours or whatever.  Ideas a year ago even can be or have arrived at an tech break thru  and do so daily.  Is there any study done on the energy rod composites.  Also we live on an island here and would like to harverst wave/rocking motions coupled with thermo(even nanosolar and wind) on same platform    any points appreciated,  bty this epoxy is premixed and you can tell them how in a variety of ways.     There is even a HV safe non conductive formula ideal for this possible "ANWSER". Also a link on porcelain ovens, seem like an affordable sum if life cycle is good. http://stores.ebay.com/dentaldental-wholesalers__W0QQ_fsubZ18339653 and if not  then an engine designed to be fired this way would be easier is build,  and 5KVpulling toward 15KV will do fine.   Funny when i posted this and the magnetic solid state rail gun that shoots mag waves amp'ed  my net when down a day.   Just coincidence but odd    first ever other than power out tho. lol

Hmmm, I am sorry you got the impression
that I didn't want to (not only) try this idea,
but try even more advanced concepts too.
(If we ever find the compound we need)



"240+ C and extremely rigid"
Sorry, not even close...



I still have the name and extension number
of the gentleman I spoke to at Epoxies.com.

Your welcome to further the conversation directly,
I'll send the info by PM if you wish to confirm their view.

I suspect the neither want nor need the liability of this.



High voltage is also a few thousand volts too sadly,
we need 50,000-100,000 volts of dielectric strength.

And do this while continually handling over a thousand degrees,
and a faster combustion shock wave than gasoline provides.
(Not merely hundreds of degrees as stated above)



Tomorrow I will open a dialog with
the "Champion" spark plug people,
it is now after business hours.

http://www.championsparkplugs.com

I'll concentrate my questions on their
stainless steel marine spark plug range.

Those look sweet for sure,
and we are burning water after all.

I may run into problems that the info we need
is considered too propriatary in nature sadly.

If that happens, I'll do AutoLite, etc. until
I get what the minimum specs are for this.

Also, I noted a gentleman that makes
racing engines in another forum too.

He may have insight into minimum specs needed.

Remember,
the hydrogen has the fastest flame propagation of any gas,
so the forces generated in an ICE are considerably greater too.

Don't believe me on this, search Google for N20
(Di-Nitrous Oxide) and melted pistons from overuse.

http://www.google.com/webhp?hl=en&newwindow=1&num=100&lr=lang_en&safe=off&q=#num=100&hl=en&newwindow=1&safe=off&q=Nitrous.Oxide+Melted.Pistons&

The nitrogen does slow the burn time some,
but the oxygen wins every time you'll see,
now add hydrogen to this and viola, BANG.



I've studied my share of plasma cutting tips, etc.
they work along the same lines as that pic shows.

But that won't work in a compression chamber,
the design will have to be heavily refined to work.

Not to mention the needed safety check valve.



There is also another thing to address,
what plans do you have for introducing
the water through this version of concept
with the compression's pressure level occurring
just after TDC in a four stroke's cycle ?

I've narrowed my ideas down to two of them,
I'll gladly share as soon as this all takes off ! 



Seriously, no compound, no point.

The velocity of a hand made spark plug's insulator barrel
launched from a running engine during a firing sequence
is NOT something to joke about in the least, seriously.

It is an extreme safety risk, and will kill someone !

There are things that can be comprimised
in the interest of validating a concept,
this is not a corner to cut...

Info is not as easy to come by as I thought on this tooic,
I will post what little I can find over the next few minutes.

"The porcelain of the main insulator is inadequate,
so a sintered aluminium oxide ceramic is used,
that is designed to withstand 650 °C and 60,000 volts."
(My Note: 650-C = 1202-F)

"Sintered aluminium oxide was developed by Siemens in Germany"

"The seal is typically made by the use of a
multi-layer braze because there are no braze compositions
that will wet both the ceramic and metal case
and therefore intermediary alloys are required."

"As the current of electrons surges across the gap,
it raises the temperature of the spark channel to 60,000 K."
(My Note: 60,000 K = 107,540.33-F)

Plasma temperatures:
Red is a relatively cool (60,000 K)
Green-yellow are hotter (1,400,000 - 2,200,000 K).
