What is awesome is that all of us can't possibly know all of the ways that these things work, we have humans specialized in everything and it's awesome to me seeing where we are at now.

I would love to know more as well, but im over 40 and my time to be speacialized at something like this has passed more than 20 years ago. I can only watch, enjoy, and meanwhile learn a few things. Love engines and machines
Being an engine machinist and Rebuilder this has been one of the most interesting videos I have seen in a long time pressurizing the bolts with oil was something that I never knew was done I learned something new keep up the good work
Mantis 0001 hydraulic wrenches have been used for years in heavy industry. They are capable of reaching torque values well over 1000 lb/ft. In some installations cal rod heaters are inserted into bolting prior to torquing fasteners. Heating the bolting to predetermined values causes the bolting to lengthen. This process results in increased torque values and bolt stretch.
Da Truth : they do not pressurize the bolts with oil. the oil is used to turn a hydraulically powered torque wrench to tighten the bolts or nuts very very accurately to a torque level that a person would find it very hard to reach with a hand tool as well as a person could not tighten multiple fasteners simultaneously where as hydraulics can ..
@@normdoty Is it a wrench that turns the nut or does the hydraulics stretch the bolt a pre-determined length, the nut run down, then pressure released? It was my understanding that it's the later.
On Pielstik engines, the nuts are run on to the head studs first, then a cage is fitted over them. A hydraulic jack is then run onto the head studs, and sits on the cage and then pressurised. This stretches the head studs enabling the nuts to be rotated until tight with a special tool. The jack pressure is then released , removed, along with cage. They are usually all done at the same time, so all the nuts are tightened at the same time and the same torque. The whole apparatus looks like an octopus, because of all the hydraulic lines protruding from the centre hub.
In many ways I prefer similar videos from the 40's and 50's. In those old films they give much more focus about the precision required, and the skill of the workers. It is almost a theme. In nearly all of the modern equivalent videos, they are always adding fake drama with stressful music and talking about all the things that could go wrong, how dangerous it is, how much it will cost if something goes wrong. These workers are professionals who do this work every day. There is no drama like is always added these days. I really hate all the added drama and the loss of focus on the skill of the workers.
It’s a assembly line production there is no skill involved you do only what is required in your section of the assembly,,, absolutely zero skill involved in assembly line workers they’re some of the simplistic workers out there, not like construction or mechanics or electricians plumbers welder assembly line workers are pretty much brainless and just follow instruction in and on their section of the assembly. I don’t mean to be insulting about this work but it involves no skill whatsoever which is why cooperation’s utilize assembly lines to produce,,,,,,, just like American car makers it’s all assembly line work no skill involved they just put stuff together and send it down the line
MTU engines are world class. Over the years they have had many owners including Daimler but are these days owned by Rolls Royce Powersystems, not to be confused with the automotive division.
State-of-the-art engineering "Made in Germany" has always blown me away. Only a few countries in the world (not talking about you China) have perfected through research and development the breathtaking and amazing engineering we've seen in this high quality documentary.
China steals and buys all of its inventions. They've never made anything worth a fuck that they didn't hack from another country. China is 100% strength in numbers. Too bad numbers don't matter when bombs can kill millions instead of dozens.
Love the video. I use to work on submarine refit doing plumbing. I was sent to do some work on a roll on roll off ship and saw biggest pistons I ever saw. 18 inch diameter on main engine. Starter motor was a V 16 the size of a 20ft container. I was doing industrial & domestic plumbing before trying naval maintenance. When I first arrived I was shown the big stuff. There in one of the buildings was a Lathe with a 30ft diameter chuck, for turning props. Brought back some memories, great video.
@@ApexPressureWash 😂 that is funny! This reminds me of a musing I had one day while driving. Police have devices that detect a radar detector used in your car in places where it’s illegal to use a detector. So, radar detector manufacturers invented a technology that could detect the presence of a radar detector detector by it’s ranging frequency. So, I thought naturally the next step in the process would be a tool that would enable speed enforcement officers to detect detectors that can detect radar detecting detectors before the driver’s radar detector can detect the officer’s radar detecting detector and block it’s outgoing energy waves before detection. Simple!
Everything that is an onset of poverty to the consumer in endless and very expensive repairs after a while in this case probably after only 3 years of service I'd look somewhere else maybe Japan American or south Korean manufacturers simple but reliable not over engineered for twice the price comparing to the counterpart just afraid
Yes, this. It's an old habit from the days of terrestrial TV that is dying hard (TBF this one might have been made for TV). The idea is that the viewers' attention constantly has to be re-engaged with danger and excitement. But this is the internet. Not many people watch any given bit of content (comparatively speaking), but those that do are _already_ interested and engaged. We are here to see technology, not to hear that precision matters and heavy things better not be dropped on toes. We know.
Indeed, I hoped we had moved beyond that kind of artificial drama by now. I really prefer youtube over linear TV because you aren't treated like an idiot, like having to listen to the artificial drama.
Ha Ha, my brother and I were talking about this very subject this morning. Ice Road Truckers and Outback Truckers. It’s a bloody miracle anything ever gets delivered with an emergency or drama round every corner.
I got to work on two of these before they were installed into the Fred Olsen, replacing power packs due to an upgrade in design. Although they are huge for a high speed diesel, they are surprisingly easy to work on. The biggest obstacle we had was getting the engines inside of the workshop as the building didn't have the overhead crane capacity to lift them. We had to move the engines into position outside the workshop using machine skates underneath their transport frames and pull them with big winches, this left 2cm deep and 10cm wide grooves in the concrete from the machine skates breaking it apart. We then had to remove part of the workshop roof and use 2 X 250 ton mobile cranes to lift the engines into the workshop. I remember the engineers who flew over from Friedrichschafen turning up to work wearing thongs (flip flops), their reason for that was that they were in Australia where it is hot.
Be happy. You could have been working on a BIG Marine Diesel - like a Wärtsilä RT-flex96C or a MAN B&W 12S90ME-C Mark 9.2. But those aren't "high speed" diesels - just very high POWER (and huge torque).
The level of quality, is amazing. If they made an engine, that would fit in a car, the builder of the carbody, would be hard pressed to make it last, as long as the engine. 😊🙋🏻♂️🇩🇰
3:10 if you're curious, "common rail" means there is a containment rail lined above and along the cylinders, filled with fuel. Used for most *direct injection engines.*
Common rail means there is one fuel rail feeding several cylinders. This is used on modern diesel and direct injected engines. Traditionally, each cylinder would be plumbed directly from the pump, or fuel distributor independently. This worked well, but any air in the system would stall the engine, and made servcining a fastidious, and arduous process. Injector technology, and more importantly engine management systems have allowed the use of common rail, and we haven't looked back since.
4 megawatts to melt that?! That’s insane. That’s enough power to run thousands of homes. Humans are awesome. We’re probably gonna end up killing ourselves but- we’re gonna leave some badass shit behind.

Then they "We are not going to blow ourselves like they did!. That's who human race helps another race from extinction, unintentionally obviously.
What a piece of incredible engineering ! I wonder if Allen Millyard could add 6 extra cylinders and fit it in a motorcycle frame using his trusty hacksaw and file?
Absolutely amazing process for casting those blocks! Time is definitely of the essence when working with molten metal of any kind. They really have the whole thing down to a science for these massive block castings.😉
This came up and I decided to check it out for a few minutes to see if it was worth watching. 49 minutes and three seconds later and I can say, "yes! it's worth watching."
Truly one of the greatest educational tools of my lifetime, these documentaries have taught me so much and it's expanded my mind in a healthy way, thank you WELT! Mvp🤠😎
What a cute little engine. Back in 1988 the largest diesel engine in the world was 63,000 H.P. 12 cylinder, 2 stroke KHIC Sulzer slow speed diesel used in each one of the largest container-ships in the world of which five were built. These were built for A.P.L. (American President Lines) and were the first 'Post Panamax' containerships in the world. (Too wide for the Panama Canal). Today in 2020 there are 80,000 H.P. ship engines.
@@keithhasafastcar Not really. Mining industry uses similar size wheels & gears running on bearings & 2000 rpm's. Remember, its a crank, but its perfectly balanced. So the centrifugal forces are not that high. This was a very over dramatized clip. Still cool to watch.
Johan Fouche The difference between 2000 and 1200 is much less than between 1200 and 4000. I’m not very educated but a crank that size will rip itself apart at 4k
high rpm for such a large engine, the really big engines on cruise ships and container ships often run under 100rpm nut of course those engines are even larger yet
@ that's a completely different application, those engines are much smaller then this by comparison and yes it is overdramatized for television any documentaries like this are
That's where skills and initiative comes into play, these people are working with guided precision and pinpoint accuracy, backed up vision judgement and clarity. This is amazing stuff from high powered engineers and technicians. Praise God for the gift he gave man be so inventive and creative!!!
I find it striking that these engines are for the most part exactly like the engine in your average car. Just about 128 times larger, assuming the 350 liter displacement is correct vs a 2.8 liter vehicle.
Didn't show the grinding of the bearing surfaces - one of the most interesting parts for me. I mean, for example, the supports for the crank main bearings (I know that crank doesn't actually run on these, it runs on the plain bearing shells.)
So the reason you never saw grinding the crank support bearings is They don't grind them..... The only thing they grind is the crank journals the bearings press against..
These bearing shells are not grinded anymore, no white metal...When scratched or due for maintenance, all to be scrapped.For this kind of High Rev Engines you just change....or collect the pistons together when they step out for some fatigue reason......
@@Limoncello666 I think he was referring to the machining of the bearing surfaces after the block came out of casting as well as the crank and cam, not the repair process, that was clearly explained throughout the documentary. and there probably isn't much to see as the modern machines are usually CNC controlled with covers or gallons of fluid blocking any working views of the detailed process ... but its always awesome to see a machine tool take a raw part and make its precision! :-)

These were built for A.P.L. (American President Lines) and were the first 'Post Panamax' containerships in the world. (Too wide for the Panama Canal). Today in 2020 there are 80,000 H.P. ship engines.
"a staggering 20 Revolutions Per Second " jaw dropped until i realized that was 1200 rpm
Thats a lot for these big engines
@@keithhasafastcar Not really. Mining industry uses similar size wheels & gears running on bearings & 2000 rpm's. Remember, its a crank, but its perfectly balanced. So the centrifugal forces are not that high. This was a very over dramatized clip. Still cool to watch.
Johan Fouche The difference between 2000 and 1200 is much less than between 1200 and 4000. I’m not very educated but a crank that size will rip itself apart at 4k
high rpm for such a large engine, the really big engines on cruise ships and container ships often run under 100rpm nut of course those engines are even larger yet
@ that's a completely different application, those engines are much smaller then this by comparison and yes it is overdramatized for television any documentaries like this are
Wow... 100th of a mm precision? That's 10x the precision of a BMW S1000RR superbike engine. Incredible.
I was relieved to discover that connecting rod temporary cap was plastic @27:58 because I was gonna remark about this guy being insanely strong.
@Kenny hello,how are you doing
How does someone even design this shit…it’s mind blowing
Team work and German engineering .... amazing results 👏
Such extreme precision that a grain of sand can bring such a huge engine to halt!
Top notch documentary. Thank you for this.
@Bruce hello,how are you doing
I'm blown away floored by the time care and tedious work it takes to make something like this. What a interesting video
Ahhhh that was so cool! Absolute precision from master engineers.
Vielen Dank allen Mitarbeitern
fascinating subject matter and excellent documentary. I can never have enough of these.
That's where skills and initiative comes into play, these people are working with guided precision and pinpoint accuracy, backed up vision judgement and clarity. This is amazing stuff from high powered engineers and technicians. Praise God for the gift he gave man be so inventive and creative!!!
I find it striking that these engines are for the most part exactly like the engine in your average car. Just about 128 times larger, assuming the 350 liter displacement is correct vs a 2.8 liter vehicle.
35 years before service work is needed? Dang! Fine German engineering!
...and here I thought the Dwemer were all gone. They're still alive in Germany. :P This is pure machine porn.
Look at that crank holy god
The horsepower figures were very impressive I wonder if I would have been even more impressed with a torque figures?
Top fuel dragster more impressive for its size
top fuel dragsters need to be rebuilt after every pass. This thing will never be torn apart if maintained correctly.@@Toosick023
The hardest part is taping before painting.
Impressive size. 50 tons! Then I googled world's the largest diesel engine -- a Wärtsilä RT-flex96C which is 2300 tons! 46 times this engine's size!
Great work on this one WELT. MTU is just another one of those great German companies! And these engines are only part of what they do!
An awesome engine and construction - enjoyed every minute of it...if I had the money I'd buy one just to look at it!
The PPE here is spot on
Didn't show the grinding of the bearing surfaces - one of the most interesting parts for me. I mean, for example, the supports for the crank main bearings (I know that crank doesn't actually run on these, it runs on the plain bearing shells.)
So the reason you never saw grinding the crank support bearings is
They don't grind them.....
The only thing they grind is the crank journals the bearings press against..
These bearing shells are not grinded anymore, no white metal...When scratched or due for maintenance, all to be scrapped.For this kind of High Rev Engines you just change....or collect the pistons together when they step out for some fatigue reason......
@@Limoncello666 I think he was referring to the machining of the bearing surfaces after the block came out of casting as well as the crank and cam, not the repair process, that was clearly explained throughout the documentary. and there probably isn't much to see as the modern machines are usually CNC controlled with covers or gallons of fluid blocking any working views of the detailed process ... but its always awesome to see a machine tool take a raw part and make its precision! :-)
Engines are so beautiful when they are clean.
awesome documentary, loved it, thank you!
Show me one AFRICAN country that does THIS! We're all the same? Yeah!
GERMANY RISING intro vibes from the intro? Love it!
Rolls Royce is British...
@Prussian Eagle YES, IT IS !!
@@stuarttimocin7929 okay but still manufactured in Germany
That’s the perfect engine for whistlin diesels mega max 😂
Hmm, no mention of rolls royce at all
i wporked with theese MTU v12 engineds, nothing to do with rolls royce, Rolls Royce supply deck geqr, anchor winches thruster units and jet drives are rolls royce. Rolls Royce Kamewa Jet Drives.
MTU
en.wikipedia.org/wiki/Rolls-Royce_Power_Systems
MTU is owned by Rolls-Royce
This documentary is another of those dumbed down affairs. There are loads of innacurate or spurious comments throughout the 50 mins. They don't know their ass from their elbow no wonder they can't identify Rolls Royce from other brands.
ultimate gearhead welding shop!
I want this shop set up!
skylights absolutely..
The cherry on top of this would have been to see how the crank case was made!
After the huge mechanical vibrator comes the shot blast chamber.
the valves of that engine are bigger than most zylinders, and it is a 4 vlave :-)
I ENJOY LEARNING 😉
Anyone else notice that the "worker" at the foundry had his face mask up. Wonder if he still works there after MTU safety management watched the video?
We had a local NEWS Photographer { small town Paper} who would take shots of us { Elec. Utility Linemen } without us knowing. Next thing we would be in local paper SANS Hardhats, Shirts , Safety Lanyards. We "corralled Him" one day and EXPLAINED our dilemma . { in a nice way } . NO MORE PHOTOS.....hahahahahahaha
Don't worry he had his safety squints on.
Thinks I will buy and try putting this engine in My Cadillac from 1958
When he said gigantic crankshaft,
When i saw it I immediately said
“ *oh it’s gigantic alright* “
عاشت اليد التى تصنع هذه الماكنه * الالمان هم بلا منافس سادة العالم فى الصناعات الثقيله * انهم مخلصون فى العمل بصوره عجيبه * الله يبارك لهم والسلام
badass. i love this kind of stuff!
Yes sir
Brother that was ABSOLUTELY FANTASTIC!! Thank you for your work and dedication.
at 14:23 you can clearly see that the link on the lifting hook is cracked!
Gosh darn that looks dangerous!
You would think they would weld that up because that is extremely dangerous.
If only they had purchased a good quality link made by Rolls Royce this hazard would never have arisen
yes i saw bottom mid ( left part of it ) section of screen , very risky
Ragnars Brother ....if your talking about the area of the outer block plate at the bottom left, that is not a crack. It is a chipped weld and is not a detriment to the block and tackle lifting hook.
Biggest admiration for Deutschland's engineering
"The tolerances are so minute that they can no longer be perceived by the naked eye."
The foreman checked the crankcase with a naked eye.
Torino Herrera editor was trolling hard
it would also be good to se how they made that big crankshaft
