Egor's Engine Reboot.
« on: November 22, 2006, 06:38:52 AM »
Hello all, final parts are made and pictures follow.


These are the lid ring holders.





The split collar to clamp the CV boot.





A small valve to allow excess pressure off when testing.





Here the valve is installed and now in to the house for testing.


First test: to apply heat to the pot. Alarm..ding..ding, air leaking out.The CV boot that was brand new is not. It was found at our local sunshine store's take it or leave it and I should of left it. This is a major problem Ed and I will have to go to C. tire and buy one now, looks like a delay.


Second test: Will have to reboot egor. Some glue and back on the heat. Alarm...ding...ding, popping sounds like corn popping, the pots bottom sucking in and out. The base of the pot is to thin. There is lots of pressure and vacuum. This pot sucks I mean blows. I will have to add a heavy steel plate to the bottom and of course this will cause a delay. Ed it looks like you will get yours working sooner then mine.


I will take the unit apart and inspect the inside. Glue on the CV boot repair let go and the displacer may have been popping, the thought of replacing it with a lighter unit now seems like the a good idea. What to make it with is the next question. It's weight is a factor. Lots of R+D and having loads of fun. Failure is an option. Back to my career.

  Sorry to hear about the set backs, I was ready to hear about the massive rpms that would need to be dealt with, or rebalancing because of vibrations.  


  If you could press the pot's bottom into a dome shape that would cure the "oil can" effect.  Thin flat metal moves quite a bit when under pressure as I was pointing out in the first installment but only mentioned the top plate.   I was concerned with the 15gal drum that I used as well and domed the bottom before I assembled it.  It's kind of like a piston under pressure/vaccum the surface area simply adds to the to the total.


  Overall it sounds like you have sufficient internal pressures for it to run.   Balancing the displacer can be done with an external lever arm and weight if the flywheel doesn't have enough space on it.  Lighter is better though.


  I've reworked mine, shortened the displacer to change the compression ratio, lengthened the stroke of the displacer, and left an out if the new power piston fails.  I can increase the stroke of the power piston and make it a bit smaller using a steel cylinder if necessary.  It's built for change... and changed it has...


  Good luck on the next run test !

  How much does a CV boot cost?

Norm, I have not bought one so the price is a guess. Between ten to twenty dollars. Could beg borrow or there might be one missing of said neighbors car. Bill
