Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

For video 1, I am heating the motor with two hot plates at 190 degree Celcius. I use a string to 'start' the motor by rotating the crankshaft. And yeah I did notice the movement in the diaphragm (expansion and contraction of air), but the most it can only push the crankshaft for half revolution then...

[youtube]http://www.youtube.com/watch?v=Hx6ZbFoMvVY[/youtube] [youtube]http://www.youtube.com/watch?v=9E34044uOac[/youtube] A failed prototype. Had diagnosed this (esp. air-leak & friction) for a couple of weeks but nothing really improved. I wonder anyone here have any thoughts? :cry: :cry: :cry:

Finalised design of my project for public reference. (except for the choice of generator)

Once my prototype is done fabricating and working, I will try to upload a video if possible.

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Ian S C: Yeah, I did noticed the sketch of crankshaft assembly in your gallery. =) I live in Kuala Lumpur, Malaysia. The fact is that I approached few engineering supply place and failed to get the exact 'Loctite silicone glue'. Anyway I will try out using Super Glue then. Thank you! vamoose: Thanks...

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Hmm... seems like cutting the wire to make the crankshafts is a better option then... but I failed to get a Loctite silicone glue over here. How about Araldite epoxy glue or other similar glue?? The primary purpose is to have a strong glue that sticks permanently right?

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Hi guys! It has been quite some time since the last post over here. I had started my fabrication work recently and faced another problem here.

If I plan to fabricate the crankshaft by bending it, how can I place the connecting rod bearing into the crank pin location?

Anyone?

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Oh I see. Thanks!

By the way, I will need to finish my progress report on this and prepare my semester exam. Will start fabricating it after my exams around May then. =)

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Huh? But there's no thread on the bike spoke. You mean you place the nut by putting glue?? or weld??

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Owh okay. In fact, there's a stationery shop that sell disc-shaped foam with the appropriate size that I need over here. So it is pretty easy for me on the displacer part. ;)

However, I still haven't figure out how to connect the foam displacer to the connecting rod yet. Any thoughts on this?

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Hi Triangle.Stirling, Yeap, after further considerations and consultation with my supervisor, I will use copper/aluminum coated with black paint. Yeap you are correct, 6 inch diameter for displacer cylinder and 1.5 inch diameter for power cylinder. Yeah the problem by cutting the crankshaft is that ...

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Halo tomostre, I guess there's a disadvantage on the stirling engine design as shown in the video right? As there will be "shadow" created by the parts, which reduces heat received by the top plate. And thanks for the great advice Ian S C!! I plan to use 6''x3" PVC tube for displacer ...

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Wow, thinner than 1mm stainless steel? Will it bulge easily after prolonged operation? By the way, my uni don't have TIG welding, only have SMAW. However, silicone glue is possible right? As I plan to use PVC pipe as both the power cylinder and displacer cylinder. Yeap you are correct. I plan to use...

Re: Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Hello Ian S C, It is my final year at university actually, but this is my first time building a stirling engine. =) I wish to use PVC pipe to make the cylinder, so the conduction of heat from the hot end to the cold end will only occur thru the bolts. However, copper might not able to withstand high...

Solar Powered LTD Twin Stirling Engine Generator (Gamma)

Hi everyone~ I am required to design and fabricate a Stirling Engine as stated in the subject above for my Final Year Project. Since I am a newbie/beginner on this matter, I would like to get some comments/opinions from you guys to assist my project along the way. :smile: 1. From what I observed, m...
