White Rose: Does it produce enough torque to drive?
Elitellamaryder: Can I please have the plans? I would like to make this in machine class at
pepersorte: Nice bit of work. I just wish i had the tools to make one this good but I
just hope i can get my one to work I am still looking for help and ideals
thanks for showwing this one,, Cheers Pete
pepersorte: I donot know if you know the oldest law for aircraft to fly, "air speed
increase presure degrease" Just where the flame goes in you add a small
ventury tube, this tube will suck in the air and the smal amount of fuel. I
know then the piston would have built up presure so at bootm of stroke you
would need small hole to let back to 1 atmospher. I like to try and come up
with new things but not shore if the flam licer I am making now will even
go yet so thout i would put ideal out to evey one. Pete
TJChagas: Yeah i know... i saw one for selling for about 400 $... i've seen the build
process, its a lot of tools, hability, free time and patience to make one.
I would love to have the tools...
noid919: An interesting idea, but the injection process would be difficult and also
the gas in the cylinder is already burnt so it wouldn't have much oxygen to
burn extra fuel. I like the way you think though!
noid919: The flywheel is brass, 64mm bar. Cylinder is aluminium, 40mm bar. Cyl legs
are brass, 20mm bar. Screws are brass, 8mm bar. Bearing pedestals are
aluminium, 6mm plate. Piston and valve are graphite, 1 inch rod (get it off
ebay cheap - search for 'graphite stirring rod'). Crank is steel, 38mm bar.
Crank bearings are 8mmx16mmx4mm, big end bearing is 3mmx8mmx3mm - get off
ebay cheap too. Tips - minimise friction, make piston/valve good fit, use
open bearings only. It's a fun project. Good luck!
nws15: can someone tell me wat is the theory of it??
Marcos Febrero: I love your project, I estoi making one but I have problems funciona.Si not
be kind enough to help you, thanks. my email is (firstname.lastname@example.org).
Manual do Motor Stirling - Leandro Wagner: Firstly congratulations! Great job, this engine model is actually quite
tricky to find the point ideial. But I believe that your engine can improve
their performance and very. Because I noticed that he sucks little fire, I
think if you find a way to improve it will run even faster. Congratulations
very, very cool. Greetings from Brazil, Leandro.
zwebx: i would like to try this on a old lathe... what blanks did you use and any
noid919: It does become less efficient as the cylinder heats up, and will eventually
stop running because of it. Water cooling has been used on these types of
engine and it will extend the run time. The flywheel is important so it has
enough inertia to turn the piston back to BDC, when the 'power' stroke
begins, but all the energy is created by the cooling of the gases.
TJChagas: Amazing.. i would love have one, but have no way that i can construct it
myself. Also i can't find anyone selling one...
noid919: Even though they look simple, there is a lot of work required to build one,
so they would be very expensive if you could buy them. When I've got a bit
more free time I might make another one and put it on ebay.
Victor Arnaiz: A bit slow, maybe it needs some adjustments
fujiwags: Still getting my head around this ... the gases cool and contract enough to
pull the piston ... I guess the flywheel has a lot to do with it because
the gases would cool that much, would they... especially in the short time
in the chamber. So.. as the fire extinguishes due to lack of fuel in the
chamber it contracts enough to help pull the piston back..? Surely once the
cylinder heats up it would become less efficient.? what if it were water
cooled ? hmmm?
Tsnafu: This is a lovely example - and first project too? Well done. It sounds nice
and sweet too with that big flywheel. I love Jan's designs
Manual do Motor Stirling - Leandro Wagner: Really it's just great to see him running. Because as all engines are too
complicated to give the best harmony in the whole system. I'm also addicted
to these engines. But as I have no way to make my own pieces, I built the
model Stirling "simpler". Yesterday also posted a new video of an engine
model alpha. But his was very good. Leandro.
pepersorte: Just a thought of mine If as the inlet valve is about to shut what if very
minute amount of fuel is injected to prolong the burn and so creat maybe
another power stroke then at far end of piston small hole to releave the
power stroke built up comprestion and eqaulize back to air pressur and then
have piston sucked back as normal This I think would give two power
strokes.. May be????? just one of my crazy thoughts, only look like you
have the tools to run tests and make great models, Cheers pete
Franky Yodi: awesome concept for generator... thanks mann
noid919: Thanks Leandro. It was a lot of work and fiddling to get to this point. I
will be trying a few things and making some changes to see if I can improve
performance. For now I'm just happy it runs, but I will be building more
model engines soon - I'm addicted to them!
noid919: The hot gases from the flame are sucked in to the cylinder as the piston
goes back to bottom, then the valve closes at the top. Then the gases cool
and contract, making a 'vacuum' and pulling the piston back up to the top
and starting the whole process again.
