10.4L Oil Engine Running @ Zero RPM. How is that possible?
HTML-код
- Опубликовано: 1 окт 2024
- A start and run of the 13hp Beijer Hot bulb oil engine from 1928. This is able to run at 0rpm.
BORE: 210mm.
STROKE: 300mm.
So the cylinder volyme is on: 10.39Liters.
When I tune the injection pump down as far as i can, it fires so little every time that the piston only bounces back an forth on the compression and fires again-bounces-fires-bounces and so on.
It is used for stationary power. Like running a sawmill for example. So the 0rpm running is to no use really, just a cool feature to the audience on engine shows. Normally it runs at around 400rpm.
So cool, this is exactly the content you watch all of at 4:30 AM for no reason.
Even better than Memes 😅
Currently watching at 4:02 am
Wow haha currently 0408 Uk time 😂
9:13pm, I'm old :D
4:46am 🤦🏻♂️😒
This is one of those cool things you see late at night deep in the RUclips rabbit hole and think "I could use one of those in my workshop". What for? You ask. "What do you mean what for? To run it, of course."
Just look at it, run it, complain its taking up to much space, look at it again.
Seems pretty good
of course!
I'm gonna change your statement a little with my case :D This is one of those cool things you see late at night deep in the RUclips rabbit hole and think "I'm just gonna watch this one more and go to sleep, tomorrow is a working day" and A few moments later is 4 in the morning and in two hours you need to go to work...
This is so true!
"What for?"
Well, to hook up to a fan to exhaust all these fumes obviously.
Schrödinger's engine, it's running and not running at the same time!😂
Great comment!!!!
Ironically, it was built before cats were required!

Ayyyy it's Dr. O! Fancy seeing you here! 😺 This ain't no Chevy Thunder or Hondoo, and it sure does make more smoke than the Avoca Smokah. 😸
We used to do this with R/C airplane 2-stroke engines; the propeller would just flip back and forth, but they'd run like that if the needle valve was low enough. Really cool, thanks for sharing!!
Thanks! Yes a RC engine with glow plug is very simular to this engine so i can se why 🙂
I would get this from my Cox .049 trying to get a homemade 18" blade to spin in hopes of making a helicopter when I was 10 years old.......the stupid things we do as kids..... still have my fingers and that engine...lol
Rpm: 0
Torque: Yes
When you need to pull that tank out of the mud
Usefulness : 0
This thing has tons of torque. Since it’s a 2 stroke it’ll run in reverse as well.
@@9crutnacker985 Untrue - with the appropriate belt drive ratio you can run all manner of equipment off of an engine like this (pumps, sawmills, grain threshing & milling, engineering equipment etc etc). Indeed, in the event of a global disaster such as a killshot solar storm, or nuke war, these may be the ONLY kind of engines that are still usable.
@@boydw1 Not at oscillating 'zero' RPM it's not.
I actually used to work on engines like this in the oilfield, they powered the pumpjacks. Thought it was pretty awesome that they were entirely self sufficient as they ran on the natural gas that came out of the well they were pumping. A few of them were converted to use crude oil to lube bearings, they tied into the oil tank and used a float valve to keep a small tank filled. The apocalypse could come and go while these guys just keep chugging along indefinitely. Ajax compressors are sort of a modernized version of this, but the air (natural gas) start system was so much fun to kick over and watch smoke billowing from a 16" stack.
Thanks for sharing your story 😊 Yes, smart thing to run on natural gas when it alredy exists!
I love the self sufficient oil wells.
There is a well maintenance guy who posts videos of them on YT.
I can't think of his name but I love his videos.
All the wells in my area have been converted to electric.
Not nearly as much fun to watch.
@@1978garfield Yeah, most of them out here are electric. I'm right in the middle of the West Texas desert, and ironically there's a forest's worth of utility poles, which sucks because I have to fly under all of those wires. Once free flowing stops, a fracked well starts off with an electric submersible pump, then to a long stroke (hydraulic/electric, usually), and finally to a conventional pumpjack. Most of the newer wells will more than likely never be combustion driven since there's already power on site, but on rare occasions you get a unique well that has tons of gas available compared to oil and water. It's more economical and productive to use a compressor and inject that gas back into the well for artificial lift, most of those operate on natural gas too. It's quite a different animal from the old hit and miss style single cylinder engines sputtering away all day and night, they sound much more like a diesel engine when running, a nice steady hum. Of course they're also computer controlled and fully automated, so when they go down you're out there sometimes for hours getting it started again, and they go down for silly stuff all the time. They just don't have the same kind of charisma and character that those old putt putt motors do.
@@Skinflaps_Meatslapper
Hmmm, maybe after the big freeze...
there might be more engines that run when electrickery doesn't flow....
@Maikro Wavee
Obviously for the purposes of these simple engines...
the oil only runs out when the engine stops.......
unless the rod goes through the block, in which case the oil runs out faster....
and it definitely comes to an end then.
My father was a mechanic for 57 years... i told him i have seen an engine running at 0 RPM.... "IMPOSSIBLE," he says as we banter, i show him this, he says, "that is 0 rpm! I forgot about these, i worked on one during my apprenticeship", then he also told me about the time he started a Field Marshall.... with a shotgun shell.... Thank you for this, very good content made my dad remember some old times and tell me some great stories. Australia had to import everything at the time my dad started as a mechanic. He just turned 70 this year and was working at 11 years old with my grandfather in his service station. He said "I never want to smell f *&king engine oil again". Also said they could run this engine on whale oil.... and did.
Many WW2 aero engines had a cartridge starter (Coffman). Many needed one cartridge to clear the engine (ignition off) then one to start with ignition on. If it failed to start, you'd often have the engine on fire so make sure you know your mixture settings. :)
Grouse story.
Grouse story - the stationary engines I’ve inherited where left on the farm of a tractor/engine collector mechanic which I bought in Vic.
@@rupert5390 make some vids of them.
Nice one is also starting a engine with a engine (pony motor) with big CAT engine in the 60s/70s
This is what people in 1928 heard when they started the engine as well. I love hearing the sounds of old engines, it's like time traveling.
As a diesel mechanic this is by far one of the coolest engines I've seen!
"Sure honey, I'll start the car.(.an hour later: ) "ok , ready to go"?
Do you want this engine to run forwards or backwards?
*YES*
So what do you do when you get it going and it fires off in the opposite direction you need it to go?

I used to think old stuff was boring and stupid. Now the older I get the more impressed I am with what people have achieved in the past.
When I first read this, I was like zero rpm? Is he crazy? Now I get it.
It's bollox really although it'd be interesting to know what speed it does actually do ! It needs a tacho mark at BDC and count the marks over 2 minutes to get RPM
It is a really cool engine though and I would like to see what the lowest rpm that it can truly achieve.
@@LichaelMewis I didn't watch the video as I've seen a video of another tractor engine 'running' like that.
Being a diesel, it's lowest RPM won't be as low as a petrol engine. A petrol engine can be started by a spark but diesels need a fresh compression of air (which heats it) for ignition.
Same. Then I was like "I see what you did there" lol technically the engine speed can still be measured as rpm, it's just changing directions.
@@c117ls7 If you measure the rotation speed over 90° and multiply by 4, you get rpm without needin a full revolution.
Just a mild revolt will suffice ;)
Holy shit. I'd lose months of my life playing with that.
Yes, its is like a drug.
Is it losing when you actually have fun doing it? I think not :)
Beats the hell out of losing it on wastehook and twatter 😉
Haha ... built so well that they last for ever and run at O RPM ! Work Horses
I've noticed that the old oily engines tend to last the longest. It seems that the better you are able to lubricate the engines, the longer they will last. I once had an old Honda that burned quite a bit of oil and leaked oil. It had 300K miles on it and ran like almost new. If it weren't for the smokescreen left behind at stoplights in the summertime, you would think it was a fairly new car. I ended up selling it (I regret this) so no idea of the fate of it.
Probably some kid driving the shit out of it lmao I did this to my 400k km civic
I’m a Brit living in Romania, and occasionally, in rural areas, you’ll see one of these mounted on a self-propelled saw-bench, with a couple of guys taking it to the next job, to cut lumber from whole felled trees.
They’re beasts of an engine, so much power from a single cylinder. You can hear them coming from several hundred meters. 🤣❤️👍🏻🇷🇴🇬🇧
Truly amazing what they made back in the day. Incredible manufacturing,lasts forever.
I would love to see it with the cooling tower in action.
Saaaaaaaame
I work on a lot more complex machinery, and I enjoy figuring out complex problems most of the time, but sometimes I think I was born about a hundred years too late. I think I would have enjoyed working on machinery like that much more.
But then again who knows, no antibiotics then, I might have died from a bad tooth or something in my early 30's
Well I guess many of us think the same way. Have nice day Joe
Good point about an early death, which was much more likely back in the "good old days".
Fewer vaccines then too. Then again, no fallout from all those tests and meltdowns yet either.
@@Einwetok lots of trade-offs. Potentially a shorter life span on the downside. Although being able to work on machines that are actually designed to be serviced, and aren't full of black boxes that the manufacturer won't release any service information for, and being able to make your own replacement parts out of locally available materials with hand tools and a few simple machine tools, not to mention no over complication due to government regulations,,,
I guess I'm looking at all this with 60 year old eyes in 2021, but somehow giving up some years of life in order not to have to deal with miles of red tape and paperwork, and being able to make almost all my own parts without being looked at like a time-wasting idiot seems like it would be worth it
sometimes I think the food we are sold can kill.us. yes, people died of simple things "back then" but now we have 50 cancers
Lol I love how you refer to this as a "little engine". I wish I had some cool old stuff like this to play with
Thanks for taking the time to explain the function and operation to start and run this engine. The principle is so simple. I find these old engines hypnotic and fascinating, especially zero rpm.
Somewhere in my head an idea is starting to form, sounding something like, "how to turn a rotary saw, into a very slow reciprocating saw."
That's how bone saws work
10:37 That old girl doesn't want to run at 0, she wants to WORK. Pretty awesome piece of machinery, and your cooling system is ingenious. Thanks for the video- I hope you turned a fan on! *cough* *cough*
Talk about dying from secondhand smoke!
I stepped away from the video just as he was starting it, and came back to find the room filled with smoke and the guy missing. He obviously died from carbon monoxide poisoning, right?
no
Ask yourself why camera is still moving around. :-)
@@mrdummy_nl lol it was a joke
It would take a while for diesel fumes to do that haha
😂 this legit made me laugh.
This engine inspired VW Diesel's emissions specs !
Lol
If only it inspired Ford reliability…
That slowest setting is for reciprocating equipment? Lmao!
No, I think it's for keeping the engine idling while it's not needed.
@@firefly618 and with a 10 min hot bulb warm up you Shure want to consider whether you want to shut it off.
I understand perfectly. That's exactly how I operate first thing in the morning...ZERO RPM!
This is how you operate when you wake up with morning wood!
He starts it at 8:00 btw and 11:23 for 0 rpm
You should watch the whole video, you don't deserve to see this thing run at 0 rpm unless you respect it.
Exactly, this video is lengthy for a good reason - it's very informative.
I rather enjoyed how it was explained. I have plenty of attention span to survive. lol. great view of antique tech.
just think.of how many failures and planning till this engine didn't tie up with friction. the stroke length alone is impressive. stroke moves things,
Well covered vid of this old grandad engine with lots of character. Nicely maintained Well done!
I’d call that roughly 80HRPM (half revolutions per minute).
"What's the redline on that engine?"
"One"
"One thousand RPM???"
"No, ONE RPM"
Music can listen all day long REGARDS Ziggy
A modern day servo motor will run at full torque, “locked rotor”, at zero rpm. Love this old technology.
steam engine has full torque at 0 rpm
The best way of varying AC voltage 100 years ago was with a locked rotor slip-ring motor whose rotor position could be varied by the angle of a single pole of the windings
@@Jeanie363034 electric motor does as well
@@Blox117 whats old is new again
@@TheJunky228 not really, its just a physical principle. the human arm also produces the most torque at zero. cumbustard failgens just so happen to stall at zero.
Still perfect for off-grid power generation. 4:1 speed stepup through an old diff should be close enough to 1500r\min. Use up old engine and chip oil..…

Thanks for sharing ,that amazing engine
Today's manufacturing should take a look at themselves for making such junk nowadays everything throw away.
i seen an engine built in the 1800's, a hot air engine with a piston that was about 2feet across was a giant water pump amazing throw in a couple of sheets of newspaper spin the giant flywheel and away it goes for about 2 hours on that little bit of paper then you just add a couple more sheets of paper and repeat until the day of pumping is over and it still runs today
Sounds like a lovely machine!
I am definetly buying this!!!!,,,,for my SteamPunk 4x4 🤣
Gonna add a turbo n blower to boost horsepower to 1,200HP
This machine is genuinely beautiful. I'd love to build something like that
"Zero RPM" is at 11:32 in the video. With the piston rocking back and forth, the engine is at basically net zero RPM. Pretty cool.
The piston _always_ rocks back and forth. What makes it zero RPM is the _flywheel_ rocking back and forth.
@@xenaguy01 If the piston doesn’t make a complete revolution, it’s at zero RPM. Same as the flywheel.
I think they are called "Glühkopf-motoren" in germany wich translates to "glowing-head-engine". Saw one of those like 10 years ago in a museum in bavaria on a school trip.
Yep thats true 🙂
It's gloeikopmotor in Dutch, so the same I guess. In English they call it a hot-bulb engine it seems. I want one.
I have never seen one before, but I believe I can add one more language to the list: Kuulamoottori. That is Finnish. The "moottori" of course stands for "motor". The "Kuula" refers to the iron balls that once were used as shots in the old artillery guns The more present translation for the "kuula" is a bullet.
@@InssiAjaton well the hot bulb at the end of this machine does look a bit similar to a cannonball, so I guess that makes sense.
@@InssiAjaton Tändkulemotor is the Swedish name. "Tänd" is Ignition, "Kule" is bulb or ball and "Motor" is as you probably guessed Engine.
Enough torque to run a rock crusher even when its just bouncing back and forth. Back in those days torque was king. Horse power ratings were used as marketing ploys. Massive farm tractors (called LOCOMOTIVES) could easily pull 26 bottom plows all day long.Now days so called horse power ratings are used to sell everything from fish tank pump motors at 1/10 of a HP, to dump trucks with 3200 HP 16 cylinder twin turbo charged Diesel engines and Torque is still king.
So true!
torque is meaningless when gears exist
hp is a unit with time included, ft/lb is not
As others have said, you forgot what a gearbox does.
Power is what's needed. You can make any torque you need with the right gearing.
This is a cool and INTELAGENT video, why don't the corporate industries work at this level, ?????
there's no over use or abuse of the earth, its man destroying you ability to work on and make viable technology.
I love old antique equipment like this, the engineering that had to go into this without any computer controls or tech that we're so used to nowadays.
Yes me too! Always works better without electronics.
Cute pfp.
reminds me of the old Lanz Bulldog. Very cool engines and build to last forever.

Sorry to mention a health thing but unburned oil is a tad harmful to the chest young fella. OK now and then perhaps.
Thank you! No it's not healty, but as you say it is not so often, so i think it is ok.
Im glad to hear that there is people in England that enjoy coffee also. Cheers /Richard, Sweden.
The Lanz Bulldog tractors were able to run at zero RPM as well (also a hot bulb-type engine).
The Lanz Bulldog will run 0 rpm until the hot bulb becomes too cold for ignition to occur.
You know the Romans could have had machines like this back during their rule. All the parts were available then, brass, bronze, cast iron, oil, they were very advanced and we still aren't aware of all of their technology. Much like the Egyptians, there is so much that was lost during the dark ages.
It's the same type of engine used in my late great uncle's fishing boat on the island of Flekefjord in Norway 🇳🇴

Somehow I don't believe that this engine would meet modern emissions standards.
About 30 years ago I had a moped with manual adjustable ignition. When the engine was hot, i could adjust the ignition so high that i could start it in reverse. Was funny letting people try it, putting it in gear and watch them fall over the handlebars as it took off backwards XD
Thanks for including a tour of the engines as well as the start. Greets form Norway!
Techno before drum computers!
I wonder, if it was used in a marine application would they be able to control it well enough to use the 0 RPM as an idle and then restart it in the right direction for reverse braking reliably?
Yes exactly as you say. Very common in siple fishing boats without reversable prop or gearbox at the time.
I never see a engine in standby mode xD
so does the pressure from the air, sucked through the leather valve make the piston to go back?
when does it drop then? why it sucks every revolution? I think I misunderstood the whole leather valve thing.
Old motors are so cool. Last 100 years or more years. Today's motors you're lucky to get 10 years out of them.
Idk if this engine is used as much as modern engines
Yeah but a modern engine does so much more work in a thousand different environments, all in a compact size.

My grandfather had a big 30 liter single cylinder engine in his old fishing boat. Took 1 hour to start. Blew nice black and blue smoke rigns out the stack. Sounded a bit like this, only it ran really slow on idle. I don't remember the make of the engine, but it was made in Norway in the late 20's. Great video. The sound brought back memories.

From what I remember many of the titles were in a Scandinavian language, which makes it kind of hard but I'd include words like "fishing boat", "troller"(trollar"?), "Norwegian", "Danish", maybe "Swedish", "Norse", "Norsk", "traditional", "local", "restored", and "engine sound" since I believe one boat in particular is restored and known/"famous" for that.

Hi mate. I sure will try! /Richard
Saw a hit or miss engine just running in a corner at the international ag expo a few years back. Damn thing was only firing about twelve times a minute but it was maintaining a solid two thousand rpm's, the flywheel was unstoppable. I imediatly fell in love with the drip carburetor. I'd love to hook up some old gear like this to a modern generator.
Oh my god I never thought about a running engine not going even 1rpm because it doesn’t make a full revolution
Yup, I want one. A few years ago the price of scrap iron hit a new high and all of the cool old stuff around here disappeared.
Sadly about the same time the scrap yards stopped selling to non commercial clients.
Used to most place were glad to sell to you from the pile if you would pay more than scrap.
Now I see cool stuff that is worth money (saw a few phone booths a few years ago) but they don't want the hassle of selling to individuals.
Those phone booths probably came back as beer cans or razor blades depending on what they were made of.
@@1978garfield As a kid we used to drive through the local scrap yard once a week to see what we could pull off the pile. I bought a mini bike frame with no motor one week and an old briggs tiller the next and had a running mini bike for less than $50.
Really cool, I love those old engines
I used to do this with an old two stroke motorcycle and get the engine to run backwards. The fun came when I asked a friend to ride it in to the barn for me and it went in reverse!!! He never rode any of my machines again following that.
thats the perfect cruising
engine for a medium sized yaht. It doesn't need highly flammable gasoline, extremely bullet proof, can run on wide range of fuels in areas of the world that are remote and coconut
oil, or old engine oil,
may be the only resource abailable. And its immense weight would replace the lead ballast, and the engine would be installed low in the hull for low center of gravity. That thing can run months on end without maintenance, which is why they are still used to this day on old oil pumpjacks
Except you have this big engine to produce 5-10 hp. There’s more modern diesels that would produce a few hundred hp and more torque for the same weight.
Thankyou for explaining the functions of this beast!! It’s amazing how this thing is designed.
Thanks 😊
after a really hard day of strategic problems, and multi year plans, so nice to see something start and finish in a few minutes !!! with such great sound and energy... love it !!
Wikipedia quote: "All two-stroke diesel engines require artificial aspiration to operate, and will either use a mechanically driven blower or a turbo-compressor to charge the cylinder with air." Apparently the Wikipedia author has never seen a Beijer engine! Great video!
That’s why you don’t trust wikipedia. Most diesel engines that were made before 1990 were naturally aspirated.
@@kn4dgs This is specific to 2 stroke diesels and it is true here. In this case the crank case and piston movement are used to move the intake air into the cylinder. That's why the leather reed valve is there.
But a hot bulb engine isn't a compression ignition engine like a Diesel.
@@Graham_Langley Yes, you are certainly correct and I stand corrected. This engine does burn diesel as well as a variety of other fuels and the hot bulb allows it to operate with lower compression than a conventional diesel engine...I assume. However, Wartsilla-Sulzer engines are multi-cylinder diesel compression engines and, although they are often turbocharged, many are naturally aspirated due to their design with two-piece connecting rod with upper rod segment that passes through a gland with seal in the bottom of a bottle-shaped cylinder.
@@Melanie16040 Your point is well taken that the piston is, in effect, the induction mechanism. And this engine is actually a fairly conventional, single-stroke, reed valve engine, except most reed valves are metallic, not leather. My comment was a snipe against Wikipedia and their statement specifically about the requirement for "blower" or "supercharger".
If you ran this with vegetable oil, it would technically be carbon neutral ;)
The title and thumbnail pic brought me here, and I'm glad it did! Cool engine bro 👍
According to Pytagoras (Factory museum), this zero rpm was a common idle setting for this type of engines. Particular when installed in boats. Having the propeller going back and fouth in the water.
Maybe it's just to keep fuel consumption to a minimum enough to sustain life and not have to go thru the whole starting process again ?
Maybe one of a few reasons, but I'm guessing.
@@MrTheHillfolk As it was explained to me the boats dont have a cluthc so if the engine is running the ships had the propeller turning. But if it was ideling at 0rpm:s the propeller didnt move the ship.
@@MaskinJunior Exactly, plus it kept the hot bulb hot. To reverse you reverse the engine. Large container ships and the like are also direct drive but they switch the valve timing and use compressed air to restart the engine each direction change.
@@alwaysbearded1 depends on how large ships. I used to work at a foundry that made propellers where you changed the pitch of the propeller to change the speed of the ship. I think those ships has constant speed on the prop-shaft and does not reverse on the main props.
@@MaskinJunior I should have qualified size. I'm thinking of the large container ships I have to dodge when I sail. But at least they have tugs in the estuary where we have to share close quarters. The smaller ships and tugs just have regular transmissions. Some might have variable pitch props where you can reverse the blades to go in reverse while the shaft still turns one way. I don't know which have which I just stay out of the way!
If you have any spare pistons laying around could you show us the bore size ? 👍👍🇺🇸
I don't have any spare ones, but i have pictures of the piston in the 25hp Målilla from when i restored it. That one got 265mm bore. Dont know the stroke, but i will make a video aboute that one too soon. I dont think it's possible to put photos here in the comments.
@@YesterdaysMachinery Can't wait to see that , thank's 😁👍👍🇺🇸
@@YesterdaysMachinery you could put pics in a new video slideshow and put a link in the comments with it pinned.
For some idea of the dimensions and rebuild/construction of this type of engine

@@JohnSmith-pl2bk Yes i follow Jenko, his hot bulbs engines are very simular to mine.
That thing is a beast!!
The best oil in the world is fish oil. You ever hear a fish squeak? No? See how good the oil is!!!!
It may be running at 0 RPMs but it still has plenty of torque to break your arm
There is something functionally beautiful about such old tech, built to last, when you listen to them, they live and breathe, built rather like the steam engines that preceded them. Great content
Yes, i think so too 🙂
