Lanz Engine Firing At Zero RPM
Vložit
- čas přidán 11. 09. 2017
- A Lanz tractor displaying it`s unique ability to continue running despite not completing a full crankshaft rotation. The Lanz`s two stroke engine uses plunger actuated indirect injection into a hot bulb, crankcase pre compression and piston ported cross flow induction and exhaust allowing it to not only run backward, but also at zero RPM`s. This state is not able to maintain itself for long periods as the small amount of fuel used is insufficient to keep the hot bulb at the temperature required to continue igniting the fuel and it will eventually stop.

As I clicked on the video I was all skeptical about something running at "zero rpm," but I stand corrected. Holy shit.
It is pretty unique.
Bulldogs are incredible.
The Metal Butcher In NZ only down south on flat cropland have I seen one,nth Island never c,In Aussie tho theres plenty,economical buggers.
Yes, the weather beaten one next to it came from Australia.
Rainhill1829 go to orchards in Aussie n see the old tractors still pullin bin trailers,amazing,easy wk for old girls.
Finally an engine that never stalls
Yea but just imagine trying to go up hill in this and having gravity take over and you start going backwards down the hill very fast,
@@nikolaiorr8383 that thing will climb just about any hill around, but I’m not sure why you would though...
You should still be able to stall it.
It will eventually stall, as this low activity is not enough to keep the hot bulb warm enough for ignition.....
CHALLENGE ACCEPTED
Never seen that before - i've seen a 2 stroke go backwards but never oscillating in both directions
At first, sorry for my English, it's not my native language.
That's very simpel. The little klicking thing u see sometimes in the video is the fuel pump. If the little "hammer" hits, fuel get injectet and get flamed on the glowing head of the cylinder. Than it backfires but at that low idle it don't get enough fuel to get over the compression. Now it goes backwards back and everything starts again. That how you start that kind of big engine (up to 10 liters huge) with bare hands (most of them don't have an electronic starter and those which have one worc with the same principle. You turn the crankshaft in the opposite direkion you want to run the engine, the fuel pump pumps a little bit of diesel, it ignite and because the piston is not over the top point, it "backfires" and runs perfectly in the opposite direction, in which you startet it and in the direction u want it.
The first Lanz doenst even had a reverse gear. All you had to do is to reduce the amount of fuel you inject to a point that the engine runs like the Lanz in the video. Than you have to increase the fuel injection kin the right moment and you can drive reverse without reverse gear
@@eintyp9201 Thank you very much for your detailed reply - I have seen folk juggle manually an injector to get a Bolinder Narrow boat engine ( Large 2 stroke semi diesel hot bulb) often needing several attempts till the motor goes in reverse - Its amazing to see
@@eintyp9201 you honestly broke that down perfectly. Didnt even need to leave to comment section, many thanks!
All 2 stroke hot bulb engines can idle like this. It takes long time to start an engine from zero, so for lunch break you left engine Idling like this and it´s burning wery little oil in this idle mode.
Not only a 2 stroke.
My Nissan sd33 engine did it well once lol.
The only problem is that the oil pump can’t pump if it turns backward, obviously. And the admitted air comes from the dirty exhaust pipe. BUT, it works even though. :-) :-) :-)
Props to the legend who is still replying comments to this day
Aw, your too kind.👍
Legend
Not all heros wear capes
Thanks
Everyone: wondering how this works
Me: * vibing to sound it makes*
Yeah same here lol.
My stoned ass bouncing and tapping my feet lol
pretty sick beat tbh
my dad explained this to me a long time ago but i dont know if i remember right...
the piston in this thing is actually so massive that it can non stop backfire whiout ever completing a full rotation. and that obviously doesnt work whit multible piston engines. im not going to explain that part now sorry.
if you have kick started a moto cross before you might know that they can backfire pretty hard. and it can hurt pretty hard aswell :D. now the reason why they cant do this, again if i remember correctly, is because they have a faar to small piston. this one is probably like a 10 litre/600 cubic inch whit just one piston! its legit bucket size.
Same.
Me: "thats impossible, it gotta just be less than 1 rpm but still greater than 0"
Me after remembering the law of averages: "well fuckin played"
What??
This thing isnt rotating lol
Motor isn't completing any rotations.
Yes you don't understand what rpm stand for , it never does one rpm , it never does a single revolution , so it can't even do one revelation per second , Zero
Ha! That's not running at zero rpm. 5 seconds later holy cow!
Pretty neat, eh.
Black magic f*ckery
Since its a two-stroke semidiesel it will run both ways. If it rocks forward far enough to actuate the injector it will fire and rock back, fire the injector again, and the cycle endlessly repeats. This was also useful for changing the direction of rotation in a boat.
@@totalwreckagelive3012 na, just German engineering :D
Yup have to revert back to combustions a minute since it won't even be doing a full stroke
official lowest rpm idle
Maybe we can get the Guinness people to verify it.
@@Rainhill1829 No verification needed, its observable.
Br!an Delta V Haaahahaha.
Cant go any lower
@@gabrieljordan9977 Just Let It Run Backwards, Then You Have Negative RPM.
"pretty goofy eh?"
Most canadian statement in existence.
Not quite
You got the eh right but no one says goofy
I love the operating instructions. “Gently shift” its classy.
Yes, whoever wrote the manual and warning decals had some serious classical english lessons.
My favorite: Step 15- Attend to TYRES.
I was ready to argue this, but I stand corrected. This engine never completes a rotation while still pivoting between rotation.
That’s incredible engineering. My applause goes out to the man keeping this machine running.
What a nice pendulum clock
"The engine for agriculture cannot be single-cylinder enough." - Dr. Fritz Huber, inventor of the Lanz single-cylinder engine
This quote always gives me hope. It is so incredibly stupid and prove wrong on so many levels yet it became that famous.
The lesson basically is that you dont need to be good, neither do you need to be right. Its enough to be at the right spot at the right time to become a success.
Next video,Lanz Bulldog with less than one cylinder!🤣🤣👍👍
Next video: tractor running on the sheer amount of anger that this engine works
@@supertramp6011Turbine engine
a hell of a beat 1:25
if i knew how to make music i would make a song with this
but idk how to
it's easy, just give it a go.
If it was a bit faster it'd be perfect for cotton eyed joe!
I need a grandfather clock making this exact sound
One cylinder engine with piston bigger than a water bucket. Germany's definition of heavy metal. You''d better make sure where the decompressor is or else you'll end up going to bed leaving the darn thing running overnight. Lanz company eventually was bought by John Deere. Not a surprise when you compared the Lanz dinosaurs to John Deere's smooth running multi cylinder tractors (or McCormick, International, Massey Fergusons which were all huge successes in the 1960s in Germany. Yet in south Germany up until this day most people will say "bulldog" when they mean tractor, just as you say "Cleenex" if you mean "paper tissue" or "pampers" when you mean "diaper". That's what you call a legend. Greetings from Germany. It somehow makes me proud to see all you fine people standing and looking at this tractor.
"How low can you go?" "How about zero?"
Dad had plenty of praise for these machines. Very tolerant in regards to fuel. Although he said you had to be careful at low revs, you could suddenly find yourself going backwards.
Very true.
I had a friend in North Victoria in Oz who's family had a Lanz Bulldog. His grandfather left it idling by the barn to go have lunch. When he came out it had disappeared. Turns out it had pounded itself through the surface soil into wet spring "cream" underneath and just sank.
He ever get it back?
🤭😯 - sounds like he parked it on the soil equivalent of quick sand, and was it completely buried, or partly buried and did he dig it back out?
Oh no.😮
@@superFordwitha Yep. It was parked out in the rain last time I saw it, which was a long time ago.
@@samuelfellows6923 The soil there looks fine, but you can get underground streams or springs over the bedrock, especially after heavy rains, that literally turns the subsoil into a kind of cream. Another chap I know fell into one in his Suzuki four wheel drive, had a hell of a job getting it out.
This sounds like a car in a cartoon
That chuffing, hooting sort of Old Timey Engine Sound from old cartoons I think has to do with the low compression ratios early combustion engines used. I'm having a hard time finding specifics but I think I've read that some early gas engines ran in the 6:1 sort of range, which at low RPMs meant there wasn't as much of a bang to the sound of their exhaust.
People with engineering degrees: this is the most amazing fuel efficient engine in the world
Ummm, you mean the LEAST fuel efficient? It's burning fuel to literally do nothing.
@@elanjacobs1 thats an old farm tractor you dingus hence why he is showing it to a crowd of people hence why it is staying still
@@yeboidustin8725 no fucking shit. I was responding to the comment about fuel efficiency
@@elanjacobs1 chill man, it's a joke
@@elanjacobs1 Ok but you have to admit, it's doing nothing VERY efficiently
I like that they have an indicator dial to show if it runs right direction.
Very handy gauge I can attest.
"why did you put wheels on your rhythm machine?" "turns out, it's a tractor"
love the sound of these old two stroke tractors
"Goofy eh" "holy man" such innocent expressions lol
Never realized, lol.
People talk about how great auto start/stop systems are these days... yet here is an engine that was idling, without actually idling...... I love seeing stuff like this :)
Neat huh.
@@Rainhill1829 Very. I see people acting like certain technologies becoming common now are new.... But many of them do not realize just how far back certain technologies taken for granted now were used or experimented with.
@@Carstuff111 Absolutely, fuel injection for instance is century old tech.
Amazing. Thanks for sharing. There is some wicked engineering on this old tractor!
Well... you can't get any lower rpm than zero and that crankshaft is not doing a full rotation.
Technically it's oscillating between
Minus point 5 and plus point 5 ...😉
@@olivergiles6731 what are you trying to prove?
Well, you can run the engine in reverse, which is technically negative RPM. And in fact that's how you go in reverse in this tractor. It has no Reverse gear. You put the engine in this 0 RPM condition and increase fuel so it runs in reverse. There are videos out there of people doing this, it's pretty amazing.
@@ThZuao Nah son
@@szewal it’s at 0 rpm
I live in Nsw Australia, every year they have an old tractor weight pull competition, every year out of all the old pre 1960 machines the Lanz Bulldog tractor or bull dozer , wins , 11 litre one cylinder , 60 hp but 1100 foot pounds of torque. All the other old machines stop but the Landz just keeps firing , will not stop , that massive piston , impressive .
They are absolute torque mountains.
@@Rainhill1829 yes incredible hay
i really love this engine, it can run back and forth and backwards, i just love how stupid that is.
All in good fun.
The earliest lanz bulldogs didn't have a reverse gear so if you want to reverse one of those you'd have to time pressing the gas just right to cause a premature explosion which would fire the piston backwards. Great video. Sounds like music. Hot bulb engines fascinate me. Greetings from Germany
Yes thats right, the HL only had a clutch and needed to run backwards for reverse, interesting.
Its 4am and I'm watching lowest engine rpm what am I doing.. all though it is quarantine so ya know
Engine stall !
reading this at 04:02 am
Update: it’s been 9 months and Shit hasn’t gotten any better
Sams
you know you're an old tractor nut when you replay this video atleast twice in ten minutes
that oscillating sound is way too dope man
Kinda musical.
Was waiting for someone to come and spit some sick rhyme over the top of this.
Heck yeah!😆
I always thought it was awesome of Peter to bring out that amazing artifact every year.
Yeah he is the best.
such a beautiful machine. I don't know much of anything about tractors but have watched some Lanz Bulldog videos because this tractor just fascinates me with its simplicity, reliability, and high torque
Very simple, very robust.
The Real Reciprocating Engine
I had no idea this was even possible, absolulty incredible
I like the spare piston in back, never know when it'll crack!
I've worked on one , it's a cast iron piston with 3 top rings and 2 bottom rings and they have never been known to break ! Most are still running with original pistons !
Wow, that's actually freaking crazy. I thought that it's probably at least gotta make a rotation one way or another. Boy was I wrong, this reminds me of my little Briggs and Stratton. If you crank the fuel mixture to as rich as possible and attach an extremely heavy flywheel to it I can make it do the same exact thing. Unfortunately I can't do it very long because of lubrication issues and I will destroy the bearings as it's a simple splash lubrication engine. No pressurized systems anywhere, that's also a very beautiful tractor!
Yeah the two stroke system in these is very interesting.
This sure has sick beats!
Kinda like music yes.
Brother that is so dang cool. That’s one of those you wouldn’t hardly believe if you didn’t see it! I love it!
Thats awesome, thanks.
Beautiful amazing machine and nicely demonstrated.
You learn something new everytime you bingewatch random stuff youtube recomends i guess lol and im not complaining! This is fascinating
Thats great, I’m glad you enjoyed.
The owner/operator/rebuilder.....is a fortunate son-of-a-gun. Thank you very, very much for this video. Mac
That is some neat engineering
Yeah they really are a masterpiece of their era.
This requires fining tuning on the governor. Ancient knowledge .
@@TheAndre8900 Yes and gloriously simple devices.
I could fall asleep to that sound.
I should do an audio session with it.
Can't beat the sound of a Lanz Bulldog!
Probably mentioned earlier but this needs to be re-recorded without all the background chatter. It would make a GREAT sample beat! No one would ever figure out what it was..
Yeah there are guys here sometimes with special mics that only pick up the machine.
Interesting this is pretty cool. I also love the sounds that engine makes.
This makes me want to pull up a lounger and take a nap.
It has a neat rhythm to it
Ladies and gents, the only tractor that can drop a beat without dropping the block.
as simple as it is, I totally love it.
I love lanz engines, because they strip a combustion engine back to its absolute most basic function.
Their true beauty is in their absolute simplicity.
Ok... that's an awesome tractor and someone needs to remix that track!
That would be awesome.
sure would be nice to know how those things run.
Very similar to modern piston ported two strokes, just the addition of a hot bulb on the cylinder head. Fuel is injected at bottom dead centre instead of top, that is what allows it to do this.
@@samuelfellows6923 sure......get up early, fill up that ol' blow torch, light it up, heat up the hot bulb for about 15-20 minutes ( go back into the house for a quick breakfast) come back out, take the blow torch out, get the steering wheel (older models) and connect it to the flywheel and start that beast, fetch the steering wheel and put it back on where it came from......aaand off you go. During lunch ........better leave it running than go through the whole procedure again. ^^ i probably missed a couple of steps, but farmers were happy to own a John Deere, International-McCormick or a Massey Ferguson with a purring multi cylinder engine that was as easy to operate as a car in comparison. Greetings from Germany
@@fatdad64able the later models had electric starters though, so it took only 3 or 4 minutes to get them running
Hear that noise? I always wondered what engines the Morlocks were running underground in "The Time Machine" (1960). Now i know.
I will have to watch that now👌
Came here for the expert comments.
Wasn't dissapointed.
Oh yes😆
The Lanz bulldog was an awesome machine
Would love to see a jazz band play along side this tractor.
I know there are videos out there of German bands playing music to these engines.
Very neat.
Cool of you to share this with us.
Thanks,glad you enjoyed.
I never knew tractors had start-stop technology back then
The Schrödinger engine, it's running and not running at the same time!😂
LOL!
I just showed this to my dad and he got a kick out of it as well
Thats awesome!
@@Rainhill1829 You are NOT going believe this! My dad yesterday has asked me if I am going to buy me a Lanz Bulldog tractor! I would love to have one but sad thing is though even if I could locate one I would be paying tons of money for it and if something breaks on it I have a feeling parts will be hard to come by and they have to be imported from Germany. I do have two IH built tractors and they are a 74 IH Cub Cadet 129 hydro and a 71 IH Cub Lo-Boy 154
The Hoyt Clagwell was my favorite tractor... when the wheels weren't falling off.
This is awesome! I doubled over when I saw the volt meter!
Oh, thats actually the rotimeter, indicates to the operator which direction the engine is running.
An unbeatable record...
Coolest thing ive seen in a very long time!!!
Well, that’s about the coolest thing I’ve ever seen!
I would not be angry if one of these engines was running outside my bedroom window while I'm trying to sleep.
Yeah it makes a real thump under a load.
Its like music to my ears
At first I thought that the engine would be somehow constantly firing but not turning the crank shaft.
This is even better.
I’d have this beat on tape in my car
I want a desktop version just to hear that cadence all day
Aw yes👌
I spilled a load of instant barista coffee powder on the counter earlier, but I was running late so I had to leave it. When I got back home, I went to clear it up only to find that because the counter was slightly damp, the coffee powder had congealed. It had then dried out leaving a solid mass I was able to literally pull off the counter in one lump with a spatula. Not wanting to waste it, I broke it into bits and made a cup with some of these bits. It tasted like cack; well even more like cack than instant coffee usually does. So don't do this people, just throw it away.
Dang this thing sounds like a Northstar V8 after it cracked the block
Ouch.
Love these engines they're so interesting!!!
Great mode for keeping direct generator runing, warm up, start stop alternative, small compressor,piston water pump,waiting between operations like drilling holes in ground or rising(telescopic)working platforms, conveyors, pottery, biscuit making machines
That's pretty amazing
Now Ill be boompatickaboomping in my head all weekend
We will, we will, ROCK YOU ! I didn't believe it either. Amazing!
Awesome, thanks.
Is it just me or the idle sound match the voice with someone talking and it starts a rap song 🤣 (at 1:49)
Yeah i thought so too!
Needs a bluegrass band playing along to the beat.
I've had the sound stuck in my head for 5 months now.
Its a great tune.
Damn, I thought my electric car running at 0 RPM was neat.
Well electric cars do have RPM, for example the Tesla Model S can reach 16000RPM, sure they are silent because they have no combustion cycles, but that doesn't mean the motor(s)are completely still
🤦♂️
@@malvage0 electric motors are capable of producing torque without moving the output shaft, but I’m sure you already knew that. That is to what he is referring.
@@kickboxs77 wouldn't that torque cause the drive shaft to move though?
Electric drive is excellent
@@kickboxs77 yep, which is exactly why Locomotives use electric motors for propulsion instead of a crazy heavy duty transmission to translate the power from the diesel engine. The electric motors directly apply torque from 0RPM.
Super heavy equipment too
Well, my skepticism stands corrected. I must fund some form of schematic that explains this. Maybe my crazy uncle Ed was right...
Oh yes just look up “hot bulb diesel” it will explain most anything.
1:00 you can make a beat out of that lmao
Oh yeah.
Looks like me learning how to drive stick
I once had a 2 banger JD in the shop for a tune up. I took the dist cap off and laid it on top of the block. I put in the new points and condenser. I turned on the ignition and hit the starter to see if the new points were firing. The tractor started and idled just fine with the cap not installed. I shut it off and restarted and again it ran just fine. When I took the cap off the rotor and dust plate came with it. The rotor just happened to be pointing to one of the cylinders and it ran just fine on one cylinder.
Excellent washing machine motor!
Crazy! I didn't know there was an engine that could do anything like this.
Not many, hot bulbs had this unique quirk to their design.
Got dat lope tune on it
This thing has a massive amount of torque to go reverse and forward at 0 rpm
See you in 2030 when this video will be recommended everywhere
Haaa, i know right.
Quite impressive!!
If I’m not mistaken this also make it an 0 horsepower engine but it does have torque. Hp is determined by torque x RPM / 5252
Well yes as it's in this mode , it has the same Hp and Torque at negative rpm as positive rpm , you want the specs ? 60 HP and 1100 foot pounds of torque at 1200 rpm .
QUICK! Someone break out into a freestyle battle over this thing's BEAT!
Neat! Great Vid!
Very cool!
So thats how nine inch nails got the beat for closer.
The dislikes are from the oil pressure
Funny enough, the oil pump is a piston type so it still gets oil even doing this.
@@Rainhill1829 oh wow that’s cool.
I assume the cooling fan is the only thing that doesn’t work with that swinging motion - as it is an axle impeller and would be blowing the air in & out of the radiator, unless it doesn’t produce a lot of heat when oscillating like that
@@samuelfellows6923 Thats correct, the radiators are placed on both sides of the fan so it doesn’t matter which way its running but if the engine is oscillating like this it produces so little heat that the hot bulb will actually cool off after a while and the engine will stop.
Yes it was designed to do this , I used very little oil , it has roller bearings on the crank , no oil in crank case , it's a real port two stroke .
