hello, I am the student of sdm engineering college dharwad(karnataka) INDIA.we are doing the project on stirling engine.we had down loaded the design of the ...
... ADVERTISEMENT [click here] ... Hi....Try dabbing a little stop-cock grease on piston. Your chem lab probably has some. Its failry viscous and holds up...
Generally the pistons of a Stirling or other small hot air engines use NO lubrication and depend on low surface friction between the piston and cylinder. Even...
Tom is right, but I am not sure what they do in this Japanese case. I have seen the sights with glass syringes and glass pistons, but did not read them...
Which is why Senft recommended to use graphite piston for LDTS (low differential temperature stirlng engine) since they self-lubricate. But wat about HDTS?...
ALL: I assume the Japanese site is the one at: <http://www.bekkoame.ne.jp/~khirata/english/make.htm> Several plans, some using glass syringes. If the glass...
You can use graphite in the high temp engine as well. It is remarkably stable with low expansion. I have used it in steel, glass, and brass cylinders with...
... that this would have an adverse effect, however. Does this imply that the amount of "real" work a stirling can perform is insignificant? What about fitting...
Isnt graphite cant stand high temperature, and they are rather soft? Does anyone has any data on graphite's property? I have asked one of the workshop to help...
In my experiance, its not so much that the output of a Stirling is insignifcant, but that many of the designs I see have pistons that are sized for much higher...
I have been following this post and was considering some options for piston material design. Anyone considered ceramic coatings. Here's a link to a company...

hello vipond50, I found the website for the coatings interesting, but I am not sure how they would be used in a Stirling. The problem of piston fit in a...
There is a significant number of egregious errors in this piece. So much so that it nullifies any credence it might otherwise lend to the cause. Sad but true. ...
(copied from a similar post on HAES) From all that I have read, both in books and on the net, it seems that there are a couple of major hurdles for Stirling...
I thought that developing a way to design an effective heat exchanger was the primary goal of this group! at least I hope it is. Once that paradigm is...
Working on a design of a Walking Beam Engine. Does anyone have any input on balancing the engine. Should the opposite end of the Walking Beam be counter...
Hi, Your balance scheme seems about right. There should also be some counter-weight on the flywheel to give a "gravity assist" to the compression cycle of the...
Hi Rick The size of the proto is a scaled up version of the tin can motor I assembled a couple weeks ago. The Materials on this proto is steel. Once i have...
Hi again Bill, It's fustrating that plans are not readily avaiable, especially in for larger engines to do real work. I like your idea to use a parabolic...
Hi Rick Thank you for the valuable information relating to displace clearances. I've been reviewing a concept of incorporating two pistons with one displacer....

Hi Bill, Sorry it took a few days to get back to you. I have been thinking about your double piston idea. It's not clear to me what adavantage this would have...
Hi Rick The dual piston concept was a thought of reducing heat or cold phase transfer irregularities, thus increasing engine efficiency’s. The cross...
When creating an engine to perform a particular task, a good place to start is to determine the work per cycle to be performed and how rapidly this cycle can...
