Testing a TWIN & TRIPLE Steam Engine! 

Why does it sounds like a mini diesel engine

Eu não me canso de ouvir kkk

Sounds great, much better than a single. It actually sounds like a "real" engine.

@@checkerboard8382 Probably because of the long stroke

I knew a boilermaker. Bloke had fascinating stories to tell. High pressure steam is terrifying yo- invisible, silent, and hot and angry enough to cut your limbs off.

Just use steam oil for live steam use, machinists oil for compressed air...

@@grigorsamsa6564 US navy procedure for finding a steam leak is to wave a broom in front of yourself as you wander the halls; if the end of it falls off, you found the leak. You can replace a broom for $5 you can't replace a seaman so cheaply, especially at sea.

Ther eisbsteam engine oil available, wilesco sells it for their models for example

@@vaelophisnyx9873 Holy shit

Realy sounds like diesel truck!

Yes and combining them to a V12 or a inline 5!!!

@@exo068 yeah that would be awesome

@@exo068 what's the point of mixing a steam engine with a V12? That kills all the magic

@@Pablotome97 no V12 steam engine because no one has build something that crazy and it would sound good I think!

100%

What does gasoline burn at? Or is the pressure more the issue at play here? We mix 50:1 for the chainsaws and blowers at work, just curious what the difference would be.

@@TheOriginalBlue62 The steam actually washes the oil off the walls of the cylinders when you use normal oil. Steam oil is made to emulsify with the steam, and remain on the cylinder walls to lubricate the rings. It’s a different environment than the cylinder of an IC engine.

@@tjh44961 Nice tip!!!!!

Three cylinders are the best. I love them too

You get an admission and exhaust on each stroke, so you’re effectively getting the sound of a 4-stroke ICC I-6 on the 3-pot!

You should start with one, to get the hang of it.

designing engine in blender with polygons? does the faceting bring engineering challenges?

Cool ! A steam powered blender could heat the soup as it made it 😊

@@johnwalker194 ?

@Casix03 😂🤣😂

If I recall the triple expansion steam engines are by far the most efficient and powerful steam engines known to man because of how well they use superheated steam

Well it is a real 3 cylinder

@MAVONA$💋 you are a fire maniac

@MAVONA$💋 get a life

Now an I5 or V10 would be great🤣

Err, it IS real.

it is kind of funny seems just about everyone is going steam engine crazy ... relearning old tech again ... but it seems instead of following doctrine people are experimenting and seeing what they can push it to and what comes from that pushing as well ... should be interesting times ... shades of tesla days

@@0623kaboom if you can produce the steam efficiently, it's a great form of power

That man is a true artisan.

I was under the impression the Titanic only used 3 cylinder triple-expansion engines. In fact, I've never heard of four cylinder triple-expansion engines before, would they not be called quadruple-expansion engines?

@@Kyle-gw6qp they wouldn't be called quadruple expansion because the third expansion is just split between 2 equally sized cylinders. They did this to reduce the weight/size of the third expansion components and to minimize vibration. A true quadruple expansion engine would have 4 different sized cylinders. 1 for each stage. If you want to see a really well done scale model of Titanic's engines, look up overweightarchie on youtube. He's got thousands of hours into it and it's arguably the best functioning model of the engine in existence.

Steam engines, wonderful things 😃❤️‍🔥

They are pieces of art in my eyes.

They sure are. I really do like the two cilinder one.

You'll notice they have functioning valve gear, this means you don't need multiple expansion in order to improve efficiency. You just move the johnson bar closer to the center and it'll close valves early, allowing the steam to generate mechanical work by expansion. In scenario of full expansion from working pressure to atmospheric, you get maximum possible efficiency. It's basically the same as having fixed timing valves with multiple expansion cylinders that expand to atmospheric pressure, except you have an option to "overdrive" it and produce more power at the tradeoff of exhausting underexpanded steam.

Along those lines, a tinkerer could try to demo in miniature, heating with a heat pump vs. direct burn.

I can see the exhaust condenser working - lots of stationary engines have them, but you couldn’t directly feed it back in as the water would have to be at a higher pressure than the boiler to be able to get through the one way valve. He could probably machine up an eccentric pump though, they’re common on locomotives.

@@harryrobinson2901 I didn't think of that. Makes sense

@sourand jaded they can be really finicky on miniature steam engines, they’re fussy on pressure and also don’t like hot feed water - which is a problem if you’re getting your feed water from a condenser, they tend to condense the water properly but keep it a bit warm. It’s definitely possible though. Some boilers need certification in the UK and US and to get one certified you need at least two methods of water input, so there’s no reason why you couldn’t have an injector and then a hand pump for if it fails.
