Re: Manson Hot Air Engine Build

Hello,
I am new to this forum.
After having, for a few years, read a lot about Stirling engines, bought, analyzed and improved some small Chinese models (including a Manson) I now plan to design and manufacture a small Manson engine.
I have been impressed and excited by the recent accomplishments of 'rmac' and 'alex.M' and all of the comments on this topic.
There is an IC Engines section on your site... Is it inconceivable to create an EC Engines (external combustion) section?
Sincerely,
Stéphane

Welcome to the forum. It will be interesting to follow the design and construction of your Manson engine. For now, feel free to post your ideas and questions here in this General Discussion area. I can't speak for the administrators, but I imagine that a new section could be created someday if there is enough interest. Actually, a lot of the folks here are already interested in external combustion ... it's just that they use it to boil water to make steam instead of trying to make a little bit of air expand and contract.

Again, welcome!

Well, well. That worked too good. Way too good! I unraveled six or seven pieces of #12 stranded copper wire and then twisted them back into a 1/4" diameter cable that would fit into the alcohol burner. For whatever reason, the alcohol wicked up the wire, spilled over onto the top of the burner lid and then onto the wood base. Before I knew it, I had one heck of a fire going. I need to play around with the whole thing some more in a setting where I'm not so likely to set the house on fire.

Yes, I've seen that mentioned here before. My problem is that I've never before gone through the exercise of taking a video, getting it from the phone (or whatever) to a computer, editing it, and then uploading it to the internet. Guess it's time to learn all that so I don't wind up being the last guy on the planet who doesn't have a YouTube channel.

Thank you.

Hello,

I was quite intrigued by your metal wick... I tried with Ø4mm stainless steel cable with 49 strands... well, it works very well, and empties the bottle completely... however, the flame (only blue, so very hot) is very short... I'm going to try with 3 Ø3mm stainless steel cables joined, to see if the flame is bigger!.
thanks for the idea!

Also experiment with a longer cable, so that more of the wick is outside of the bottle and exposed to the air.

Indeed, the flame is higher and it is roughly proportional to the length of the wick. I had 5mm out (reminder 4mm stainless steel cable) I took it out 10mm to have a flame twice as high... disadvantage, it takes up more space and the flame is orange on half the height.. .
I will test it on my Manson model and I will let you know.
As for my Manson project, I am still designing and drawing for now. I think I draw a lot of inspiration from Jurgen BLADT's concept:
