This is a Stirling engine a miniature version of the real thing to be specific and I'm not
just showing you this engine to show you this engine I actually have a plan in mind if you've
seen any of the previous episodes you know
I like that I like pushing things to their limit
and this is going to be no different I want to see what the maximum rpm is that I can
get out of this engine with the intention of blowing it up but before I do that I want
to show you how this engine runs the way it comes if you buy it and then move into the
high RPM runs right after that
as you can see this engine is pretty cool and functions perfectly it runs it's a real
engine in my opinion this is an awesome little engine for the price because it's literally
a miniature version of the real thing I think a lot of people will enjoy this engines so
I put a link in the description below if you want to buy one and I get credit for every
single one that you buy so by as many as you want and the way these Stirling engines work
is you have a hot piston here a heat exchanger and a cold piston here it takes the heat that
is created by the flame at this hot cylinder and converts it into rotational ForceI did
a little video while I run this engine non-stop for 3 hours straight now that you see how
this engine runs normally and we know it can run for at least 3 hours I want to see not
how long it will run but how fast It can run and the way I'm going to do that
is by turning up the heat
I'm going to heat it up with the MAPP gas as hot as I can get it and
see how fast I can get this thing to go
right away it started moving
here we go maximum rpm
oh yeah
geez practically melting the glass and still nothing's happening
all right well that
that answers that question looks like I got about 4000 RPM out of this engine but who's
number which doesn't sound like a huge number but if you think about the fact that most
Stirling engines run between 400 and 600 RPM with certain designs getting up to 1,200 RPM
4000 starts sounding pretty impressive this is kind of unfortunate I mean we have some
damage but not the amount of damage I expected the whole engine is pretty hot this whole
thing is hot but the weird thing is that the cylinder isn't damaged but the Piston has
melted if you look inside their the Piston is melted but the cylinder is undamaged I'm
telling you this really surpassed my expectations I think it's definitely worth the price that
they're selling this thing for because if it took that I mean man definitely worth its
weight in gold that's a little bit exaggerated I can't believe the Piston inside Melted but
the cylinder is still intact it's the strangest thing I'm not sure I'm going to actually try
to take this apart and see how this thing oh look at that it's like loose what the heck
oh goes the weasel look at that there's little o-rings in there oh look at thats are damaged
oh man look at that piston looks like a little icicle I think this would have stood running
a little bit longer but it definitely melted the Piston inside of there I want to open
this up and see if we can somehow just take this apart crazy look at that this is just
like a steel piston inside of a piece of glass that fits inside of another glass tube which
is the cylinder that's crazy it fits so tight in there wow how they get that to such a fine
tolerance is beyond so now I'm going to take this little retaining ring off of the connecting
rod and I think this whole piston is going to slide right out of that cylinder oh yeah
it comes right off that's kind of cool you can take this whole thing apart with no tools
oh there is goes I can just slide this whole piston right outoh that's pretty cool this
is super simple look at that thing it's just this piston this steel piston inside with
a connecting rod it's attached to this glass piston
it looks like you can just oh their you go
and this piston slides inside it all comes apart with no tools that's pretty cool
so I guess all I need is this glass piston right here and I'll be back in business so
maybe I should try that and try this one more time let's see whats inside there it's just
like a little glass tube such a simple engine it's just a hole in the heat sink and a little
vent hole here 2 Pistons 2 connecting rods and a flywheel and a counterweight I wonder
why this engine never made it that was pretty uneventful I didn't even get to do any of
my load test or my second idea because the engine didn't make it through the first idea
but I told myself if something is intended to be a full episode And it doesn't work out
I'm still going to post it because sometimes things just happen but they're still cool
