New Pre Chambers Available?

[NintendoKD]

I'm an angry scientist, remember?  I have a 150kva x-ray transformer in my garage for Tesla coil experiments, I think that I can manage.  I may not be able to use the exact formula as stated in the patent, however, I may have some leads on where to get the materials for a suitable material.  I will need some precups to use for the reverse mold, and if all goes well, then I can make multiple, and put up a nice writeup.  Everyones problem of finding precups for their respective heads will be a thing of the past.  In case anyone was wondering, this is no longer about making new precups, this is about SCIENCE!

you have a Xray transformer in your garage?  cool. now all you need is an 1800*+ easy bake oven

This is the image that now comes to mind.....



Be that as it may, I'm down for a new set of precups when this come to fruition

Geez-and I though I was an alchemist cause i can make a furnace running on veggie oil...

  Tee Hee, I was planning on running a pressurized browns gas setup via Square DC pulse to power a homemade hydrogen furnace, anyone want to melt titanium?   I suppose I could see it in the cards for using the same setup for making some VERY AWESOME!!! VERY CUSTOM!!! precups from a composite ceramic

To my biggest fans JK,

...sure am glad you're on OUR side, KD.

There is this really nifty guy from BC named hutchison, he has produced some very interesting phenomena with his high frequency, high voltage experiments, which one day I hope to recreate the effects of.  I don't believe that the guy is the next einstein or anything, But I think that there is something to what he is doing, I suspect it has to do with non-control environment, and maveric electrical components "vaccum tubes are likely responsible for some very interesting field effects"  Sorry I got off topic but the picture gave me a good laugh, looks like me, just not as bald.

Neat info, I paid special attention to the air cell chamber section of the article. I think that If we are going to play with fire we should plan on burning more fuel   A redesign of the precup is in order since we are looking for replacements anyway why not go big?  This will directly effect the maximum rpm capability of the engine, hopefully, in a positive way.  The key is the fast moving air concept over direct injection and it's slow moving air.  More complete combustion of fuel/air is achieved, and with the right design, I'm sure that we can revolutionize and perhaps revive the indirect injection engine tuning scene.  I'm no Einstein, but I do know that together, we can achieve anything, and this is no exception.  So how bout it boys?  Ceramic composite precups with an improved design perhaps using an air cell chamber design?

found this too:http://www.eng-tips.com/viewthread.cfm?qid=151792&page=45

looks as if there is a slight lip at the bottom of the cup, removing it for production would possibly yield greater area mm2 however this can be compensated for by greater wall thickness, gentlemen, we can do this.  Any suggestions for the design concept?  I was thinking of using a sort of rifling or screw design to assist in the swirl in the swirl chamber so to speak, and a jet chamber in other words a narrow opening with a small bubble and a big opening on the other end similar to early rocket designs in order to propel the hot air/fuel mixture into the combustion chamber.  Thoughts?  I was also thinking of using a screw in design, and need to use a common thread pitch so that the fact that composite ceramic doesn't expand like aluminum does when it gets hot so the precup needs to stay in place.

Some good info on machining inconel, perhaps we can make our chambers from the raw alloy? as a substitute for long R&D on the ceramic route.

Gonna give a couple o these guys a call on tues, see what I can see, in at least the inconel direction.

there are other inconel machining facilities in N America, and you can bet I'll call them and give them a darned good excuse to manufacture at least a limited production line of precups for all our engines

are these gtd or AAZ
or are they both the same 

[NintendoKD]

yes, do tell, supplier name location?  I know it's vw, but.....

[Baxter]

1.9D/TD/TDI part numbers start with 028
1.6D/TD part numbers start with 068.
1.7D part numbers start with 033.

Just the same as part numbers for the other car parts, the first 3 digits tell you what it's from.

155 - MKI Golf Cabriolet.
147 - MKI Golf Caddy (148 being the right hand driver version)
251 - left hand drive t3 panel van..
171 - MKI Golf, left hand drive....

Same with engines, 2.4D 5 cylinder start with 074..

So, that part number is for a 1.9D/TD

I should imagine, using a bit of reverse engineering that the 1.6D/TD part number would be something like 068 103 391 or there abouts.
