- What an oddball! A friend gave me this engine to get it running and see how it was held together. It is one of a kind and someone has a lot of blood sweat and tears into making it. I'm assuming its from the 1940s based on how its built. and should be cool to see it run!
Hope you Enjoy!

That engine is what is called aProof of Concept built in a Lab of a engine company around the early 1900s. Companies like Fairbanks-Morse had Labratoryies which they had to build Proof of Concept to make sure they would work and test prior to going into building a Proto-type engine. My Dad used to work in a Crane company which was started in the late 1800s and they had a lot of stuff like that!
A lot went into that engine.
This Engine was a young boys' high school Shop project to demonstrate the youths knowledge before graduating high school Mechanical and Mechchine Shop course. For this Engine to still be around today, this young person had to take first place ribbon. Those that did not win would just scrap thier projects.😊 Thanks for sharing this piece of history with me.😊
Some dude never thought that his home built engine from his HS Science Fair project would ever be in a tear down and run video! 😊
I have made things in my life i bet someone will find cool in 80 years to!
It's likely so old that movies with sound would have been relatively new. So it would have been much more profound than that. An entire
short film made about the engine he built.
@@theodorgiosan2570 Not likely that old, looks more like 1940s to 50s tech but pretty impressive in that almost everything is hand made right down to the chain.
@@cruddycornstalksprobably your future grand children
That's one hell of a science project!
So what you have is a four piston, four valve, single combustion chamber high expansion ratio model engine. Someone was exploring thermo dynamics trying to extract more energy from the fuel by increased expansion ratio. As others have said a proof of concept model, it deserves to be in a museum. The construction hours in that model shows the dedication the builder had, the construction techniques are brilliantly simple. You don't need big frame bolts holding the cylinders and heads down when all the forces are balanced by the other pistons, it's the crankshaft that holds it all together, brilliant.
the crankshaft in my machinist/engineering opinion is not beeffy enough to withstand a lot of stress. after editing the video that was what I narrowed down to the weak link in the structure of the engine. despite looking big in the video because how close I filmed the journals are only about 5/16 thick . with no bearing braces from the upper throw and the lower throws it almost has to be flexing as it runs. that and the home made chain. I had to readjust the tensioners twice top film what little running I did .
It would be nice to make a close tolarance and stronger engine with the same bore and stroke and cooling. Just to see how much power & tourque it can make on a given amount of fuel. IT'S JUST BRILLIANT. It does need to in a musieam and taken care of thanks for the video👍
@@peterupsall8542 it could definitely use a water jacket.
Close. It doesn’t have valves. It has vanes like a 2 stroke Detroit.
Oil drip pan is the base….
This must be the best "Abandoned for 80 years. Will it run?" project video on youtube so far :))
What a lovely engine! I'd be tempted to clean it thoroughly, then do a planned video of it running. Afterwards I'd stick it in a plexiglass box on display. It would not last very long as a runner, but is truly worth preserving in it's as-built form for all to see.😍
My friends and I are way to hands on to lock it in a box. The weathering on it shows it's age well and I bet it wasn't spotless when the guy made it. So this is how it will stay
A really impressive build. Makes me wish I knew who built it and that I could meet and talk with him. The time he must have spent doing this is incredible. The chain simply whigs me out. I've built engines before and I never even THOUGHT of making my own chain!
I'd love for someone to show up and say they know where it is from. Be cool to hear the story
Fascinating ! Possibly a proof of concept prototype. All the appearance of being a century old . Maybe the brain child of an early auto or air craft designer . What a Gem !
it is truly a unique piece
hobby engine.... a prototype would not have hand made chains and gears it would be all off the shelf stuff, faster better cheaper... and really the only explanation for it not to be that way is it being a hobby engine.
That's a work of art.
yes it is!
Thanks for showing this to us! Im a machinist / builder and am in the middle of fabricating a 2 cylinder TF engine. Perhaps a bit more agressuve then this example but still this is soooo neato! Thank you so much, for letting me see another machinists ideas and approach..
It be a fun project to make an improved version of this with more understanding of how engines need to be designed.
Very Impressive! Nice going on getting the homemade engine running.
This type of vertical opposed pistons engine was the trademark from a French car manufacturer named Gobron-Brillié. They produced big luxury cars with 2, 4 and 6 cylinders with opposed pistons from 1885 to 1922. Their biggest 6 cylinder had a displacement of 976ci ! Most of these engines had side-vales but in 1921 a sleeve valve version was offered.
They were the first in 1904 to hit 100mph (103,55mph) setting thereby a new land speed record.
Could you believe there is one in Argentina? It's a 1911 50hp model which belonged to the founders of the town of Intendente Alvear. It was restored in 2011 by the town government and a group of enthusiasts. Unfortunately most of the body was gone so they had to fabricate a new one.
@@douro20 I know of that car, it's a dark blue 40/60HP open tourer. There's a good reason he chose that car, it was designed to run on anything flammable (it could run on Alcool) making it a good pick if petrol was harder to come by than booze.
The Tsar had a number of Dellaunay-Belleville that were know for their reliability,
you can see that as buying an exotic sports car to differentiate yourself from your neighbor.
Great work has been done by the builder of that machine! My deep respect to who ever made it! Fantastic to see it running. Many greetings from Germany!
Beautiful little model engine. A very dedicated person put many hours into building this jewel. Great find!
Impressive understanding of the Otto cycle , at first glance I thought it was a two stroke opposed piston engine like the Commer TS3 Truck engine , but this is a four-stroke ! Commer TS3 Truck Design was around for decades , I worked on a farm when I was an apprentice and one day the farmer said " bet that you have never seen a 3 cylinder engine with 6 pistons , one crank shaft that drives rockers with 6 pistons , and the pistons meet at top dead centre , and it's a two stroke , and it's got ports with no valves ! I thought they were having a go at me ! But please look up the Commer TS3 engine ! Legend the opposed piston engine !
Intriguing. I've always thought the hit or miss engines could be an answer for many applications.
Man that is neat, some people have magic hands.
BRILLIANT DESIGN!!! I LOVE how the top 2 pistons are connected to the crank shaft!!! 🤯❤️🎉
Some find, glad you took the time to show us. Very nifty. Thanks a lot.
no problem. neat piece that deserve to be seen by others.
@@cruddycornstalkshopefully you can dig some more vintage motors up for us
@@deborahchesser7375 I try to make a video every other week. Just doesn't always happen
@@cruddycornstalks oh I get it, it’s plenty of work and it’s appreciated. Hint hint, old bikes are a blast because you can ride them after doing the work lol. Thanks brother✌️
...wow! I LOVE home made stuff like this. So awesome!!
That is an amazing and fairly unique way of building an opposed piston engine. Ive seen plenty of double and triple crankshaft as well as single crank rocker style, but this is almost like a steam engine or early coalgas/natural gas engine with that extra crosshead throw.
I'm definitely filing this one away for if I can ever have tinkering time.
Edit: Very similar to a Junkers-Doxford style engine. Incredible tech.
Yes. Very unusual for sure!
I've worked on engines all my life and that thing is amazingly built and I understand it
You have something
Wow. Very nice beautiful engine
thank you!
Absolutely amazing project!
Im glad it ended up in good hands to show it's glory!
Thank you. Try my best to take care of things!
I'm a sucker for cobbler engines. Thanks for the content!
I didn't realise the video was from you Mister Cruddy. I was truely facinated with this a home made little engine. You are right why would even bother to make chain and gears. Must of been fellow who made this. Very cool.
the guy who built this was very skilled and clever. hats down.
Absolutely fantastic engine, absolutely fantastic video. Please keep up this great work. Thank you so much for sharing, the engineering world is blessed with what your doing here.
What an amazing find! You get all the good stuff LOL! I can only imagine the amount of time which went in to the construction of that engine. Blown away at the hand-made chain links and sprockets. Your piston ring o-ring modification worked well. I am sure you feel it's an honor to have this one-off piece in your collection. It makes me wonder what concept the builder was exploring. It looks like it might be possible to achieve perfect primary and secondary balance with that design, for one thing.
good video!!! Thank you for showing us this and yes the craftsmanship is amazing.
Thanks you
Just amazing!!!thnx for this dude...just love it😊
That's awesome! Thanks for sharing. This guy built his own engine to prove his theory would work wish more would put that much effort in nowadays.
Absolutely amazing craftsmanship 👍
Absolutely beautiful piece of work.
Thank you.
Beautiful little machine
That's a cool design! I've seen Opposed piston engines before but the elimination of a second crankshaft is very neat.
That's a really cool piece right there!
One of the best videos that I have ever seen. Spectacular!
Thank you
This is absolutely amazing craftsmanship
Man that’s amazing and it runs smooth too
Just cool as hell thanks for sharing
Very cool engine! And it really runs. good video.
Are there any Markings on it?
Thing belongs in a Museum, really a Awesome little engine for sure 👍🏻
Not a single mark anywhere no numbers nothing. a true mystery
The person who made this was a genius.
Great video 👍👍👍
That was amazing little engine.
That thing is amazing someone put many many hours into that engine.
oh yeah there has to be months of work into making this thing.
This is incredible. I am just amazed by it.
The guy who made this was a genius
He truly was
Well done 👍
Nice find. It's awesome
Thank you
That thing is dukin awesome man,i love the chains.
It definitely is something special
Very cool thanks for sharing 👍
epic engine!! endless hours of craftinbg this marvel
This is impressive. Glad it worked out. That’s life without cellphones and computers.
Beautiful!
This is the first opposed piston spark ignition engine I've seen! All others have been 2 stroke diesels, which lend themselves to the opposed piston layout, the Napier Deltic the most complex, a 3 crank, 18 cylinder, 36 piston design.
Very few brands used it as it didn't really give enough benefit for being gas powered
That is very cool! I have been interested in the opposed piston design of Achates Power.
How coool is that machine! Wow.
That's awesome!
That's pretty amazing to be hand built. That should be in museum
Dont you just love those 40 mile long nits & bolts. You just turn & turn & turn. AND IT NEVER SEEMS TO END!🤣🤣🤣🤣🤣
it has the cool factor for sure!
this is a super cool engine!
Way cool Mo D!
I am at a loss to understand why you call it an "opposed" piston engine. When I was a kid my neighbor gave me a "Standard Twin" powered 2 wheel walk behind cultivator tractor. In a "Standard Twin" engine both pistons go up and down at the same time like the one you have there. That engine was commercially built by The Standard Engine Company Minneapolis Minnesota. It was a very unique design and it ran great. Whenever I tell anyone about it they say it couldn't have had both pistons going up and down at the same time or it would have vibrated. All I can say is the pistons went up and down together fired alternately and it did not vibrate at all. It ran smoothly and sounded great. There are a few videos on RUclips where people run them if anyone would care to see one in action. After tearing that tractor all apart at least a dozen times I learned all about it, and I often wondered why John Deere designed his 2 cylinder tractor engine pistons to go in opposite directions causing an "odd fire" engine. Harley Davidson did it to save width, but width wasn't rally an issue on a tractor. OK, I said my piece, thank you for putting your hand-built twin on the internet. ben/ michigan
Did you say nothing special ? No youtube, no cnc, just books and friends, hand tools... Its amazing! Handmade carburettor? Its absolutely fantastic!
Can I close my mouth now..... unbelievable...simply awesome.....
Awesome 👍😎 that is a good engine
Amazing!
Pretty impressive!
Awesome how it runs so smoothly since a lot of the vibration is cancelled out
Way cool. Thanks.
Awesome!!
Outstanding!
That is a cool find
Really cool.
That’s an amazing find! Should be a lesson that you don’t need all the tech of a modern engine to get something to work.
Work efficiently and be clean… another story of course.
Totally cool man!
Thats so cool someone definitely was in school when they made that. Or it was a concept for a bike mower or something. 2:55 it looks like an old battery tray.
I think it's beautiful
Nice engine,👍👍👍👍👍👍
wow thanks very cool
Picture this. When this was built there was no youtube, no internet, no social media. Whoever built this never would've imagined that one day some strangers all over the planet could admire his creation through a small window we call smart phones. Amazing world we live in today for sure
We lived without Internet for two years back in 2013/14 and in that time I made two motorized bicycles and the one drove me around a few hundred miles.
@@cruddycornstalks that's actually pretty cool! I build cars as a hobby, but still use the internet while doing it
Looks like a student project from the 50s or 60s.. trade school project.. interesting though barrel fins weren't incorporated to disipate heat.. proof of concept it runs under its own power..👍
Incredible. I love it
Thanks I do to.
That is AWESOME.
Very cool! Somebody had a LOT of time to kill!
what i would love to have seen is an explosion view of all the components neatly ordered.
And perhaps a few detail shots of the more complex parts.
Just to learn what makes this "clock" tick.
Would love to see how combustion chamber is configured with one spark plug for 2 cylinders. Do both cylinders compress into 1 combustion chamber. At any rate a great collectors item to study and enjoy.
You are correct. The guy just drilled a common hole between the two cylinders and that's where the sparkplug is.
@@cruddycornstalks So there are 2 intake valves, 2 exhaust valves , 2 cylinders , 4 pistons all into one combustion camber? I say it ranks up there with one of the most unusual internal combustion engines ever built.
@@oldamericaniron5767 yes correct. It very much is.
There is enough hardware to run an even-firing 2 cylinder engine. It only needs another spark plug and a distributor. The nice thing about this engine is good primary balance due to the opposing pistons.
Now this is cool
Off setting the crankshaft to the compression side of the cyl8nder is a common way to almost completely remove oval wear pattern on the piston and cylinder.
Additionally important to high compression motors.
Imagine the hours put into making this. Interesting find.
Nice! I think some ww2 planes had opposed acting engines & also large Diesel power plants with 3 v engine piston/cylinder assemblies faceing each other in a opposed triangular manner. I wonder if the inventor was closeley involved with one of these engines at some point. Circa Post war suburbia was influenced with a lot of very clever d.i.y shop projects from Popular Mechanics magazines "build your own bench belt sander or mabie a homemade experamental helicopter/autogyro"... & hobbies like controll line airplanes, Go Karts/ Minibikes, & train layouts or slot cars to name a few... Very clever people around then. Now we get those lame life hack videos & kids eating tide pods for thier ticktock chalanges🙄...✌👍
Hard to say. The most common opposed piston engine is the Fairbanks OP engines. They are still used in peak power draw power plants to this day
Junkers jumo diesel (think stuka dive bomber) had an inline opposed piston, forced induction 2 stroke configuration. Pretty sure the delta configuration engines were British, not german. Small ones ended up in trucks, big ones in trains if I remember right.
what you have is a modified copy of the French company Gobron-Brillie and their gas engine design from 1900. Although the maker of your engine has only used a 3 throw crankshaft, the original design has a 4 throw crank with the 2 inside throws operating the lower pistons and the outer 2 throws worked the upper pistons.
Junkers made aircraft diesels 6 cylinder 12 piston engines that used 2 crankshafts that were geared together and were 2 stroke diesels with forced induction to supply scavenge air ( as used in the Faibanks-Morse engines) they were used in larger multi engine aircraft, Mainly the Ju86(only some versions) and some models of the Blohm+Voss flying boats. they were never fitted to the stukas.
The Junkers engines were license built by Napier in the UK as the Culverin. Napier during WW2 then started to consider the deltic (inverted triangle) design to fulfil an admiralty requirement for high powered light weight engines for use in fast patrol craft (think PT boats and small cutters) and small mine sweepers. the deltic engines would then be used later in the Class55 (became known as the deltics after the engines) and the class 23 locomotives.
Junkers also built 2 stroke opposed piston engines that used a 3 throw crank per cylinder with the centre throw working the lower piston and the 2 outer throws working the upper piston. (similar to your engine but reversed)
the small models of this style were used to power pumps, generators etc. and also in some early model diesel trucks and other construction style machinery. the larger versions of this style of engine were used in marine and large power generation and pumping applications. Doxford engine works ( part of the shipbuilding firm) built these engines until closing in 1980.

Thing is made more reliable and easy to work on than stuff made in 2024
So cool! Wonderful comments below.
Bro you were holding an absolute piece of history that thing belongs in a museum somebody put thousands of hours into that I bet I really want to know where it came from and who made it now have you gotten any more information on where it came from?
I have not. no one has come up with anything nor have we found anyone.
I guess the builder didn't have a TV!
Cool!
That's nice
I'd like to see the home made rings just to see what they look like okay thanks Charles
Perfectly scaled down version of a normal piston ring.
It deserves to have the rings retempered so it remains original.
You can only retemper rings so many times and these would not be able to.
