Mega Diesel Engine made in germany. MTU (Engine and Turbine Union Friedrichshafen) is a brand of Rolls-Royce Power Systems. Their propulsion systems and large diesel engines, for example, neatly heat ships, heavy and military vehicles or railways. Not infrequently bring such drives namely achievements of up to 12,000 hp. The mega diesel engines are manufactured in the idyllic Friedrichshafen on Lake Constance, but the engines "Made in Germany" have long been used worldwide.

No, in this case, crankcase is the correct term since the cylinders themselves seem to be their own castings. A block is usually one single casting, but in this case the crankcase alone is a single piece.

[@tamahome321]

The issue with the MTU engine is that the A10 and B10 cylinders are the closest to the intercooler which meant that they take the most thermal stress when the engine goes full rev and idle. Constant replacement. Also the exhaust thermocouples are constantly coated by carbon and they bend easily due to high temperatures, causing false temperature which activates the engine auto shutdown active.

Is MTU a Rolls Royce company? Regardless, I've watched 3 variations of this beautifully made video, and really enjoyed them all. After my apprenticeship as an industrial electrician in the N.E. English coal mines I left, and joined my first ship (the "Port Lyttelton") in the British Merchant Navy as 2nd electrical engineer just after my 20th birthday in 1969 (I was in heaven). The "Lyttelton" was built in England in 1946 (I don't remember which shipyard, I'm 73 now, so some details from long ago are a little blurry). The engine was a 5 or 7? cylinder triple-acting two-stroke "Doxford", made in Scotland. It (the engine) was 80ft long, 40ft tall and ran on semi-refined, nasty black crude heavy oil which resembled runny treacle or molasses. We had less than 7,000 hp, and cruised flat-out @ about 11 knots (7 weeks to get to NewZealand from Antwerp in Belgium, or from London, England). So, it would take eight (8) of our "Doxfords" to equal the four MTU's output, but the eight Doxford 1946er's combined, would occupy more space than the ENTIRE catamaran ferry ship 😲 !!! If you want to make your own comparisons, please Google "Doxford triple-acting two-stroke marine engines", and be prepared to have your mind blown. Happy new year to you all from sunny S.Louisiana, USA.

Tolerance is is a restriction on a dimension.

In the late 70's, early 80's I modified Detroit Diesel engines for marine applications. We offered some 16 cylinder, twin turbo models, rated about 1300 hp (I think...long time ago). They are john-boat engines compared to these MTU's! Amazing process to assembly these bad boys!!

These engines are a masterpiece of imagination, design, engineering, technology, materials, manufacturing and construction! Exacting precision at all phases and stages and in all systems, components and ancillaries is crucial. With advances in metallurgy, engineering, production and testing processes comes improved and extended refinement and reliability. Thank you for this highly informative and entertaining insight into the production and field maintenance of these superb series of high performance marine powerplants!

Amazing. Reminds me: I had a submersible water well pump made by the German company Lorenz. It was powered by DC from solar panels. It could take DC from a range of voltages (up to 72!) and convert it to AC 17 volts. It's still in service after 20 yrs of daily service. German engineering is tops.

[@jerrycny5519]

Excellent documentary, but there was an error in comparing the weight of the engine to that of a steam locomotive. Locomotives did not weight 48 tons, perhaps only the very earliest and lightest ones. Average steam freight and passenger locomotives weighed 200 to 400 tons. The Union Pacific Big Boy weighed 600 tons. My grandfather was an Engineer for the Baltimore and Ohio and used to operate the Baldwin and Mikado steam locomotives.

[@londonalicante]

Not an error, a slight exagerration. Mallard (British built, service 1938 to 1963) holds the steam speed record at 126MPH (while pulling a dyno car and 6 passenger cars) and is the most obvious example I could think of for a reasonably typical European passenger locomotive which was advanced for its time (continuous running at 100MPH.) It weighed 167 metric tonnes, so a little over 3 times the 48 tonne weight of this diesel engine. So the only problem with the claim is that they mean a small steam locomotive. On the other hand the Big Boy was (according to Wikipedia) the second heaviest steam locomotive at 600 short tons (2000lb.) This video uses metric tonnes which are larger (1000kg, almost exactly the same as the 2240lb long ton.) What's weird about this video is hearing metric units in an American accent.

[@jimvick8397]

I worked for years in a remanufacturing shop for MTU series 4000, CAT 3516, and Cummins QSK60 diesel engines... And I was always blown away by how nearly perfect the MTU engine blocks were milled... Every mainline and cylinder bore I ever measured (if it wasn't burned up or blown up) was within .0002-.0005 of spec... where Cummins was always +- .001 and CAT+- .0015.

Those are crazy tight tolerances for a huge engine.

[@jimvick8397]

@@justinlea2406 You aren't kidding... One of the final proceedures we performed on engine blocks was to "test bar" the mainline for the crankshaft. Essentially, we torqued up, honed, cleaned, and then oiled the mainline on a block. Then for each brand and model of block we had long custom milled metal cylinders that tested the diameter and alignment of the mainline. If the block was bent (which happened very rarely) the test bar wouldn't go and once in a blue moon it would wedge in (very not good)... Anyhow, the MTU series 4000 had such tight mainlines that you had to yank the test bar out full force as to not risk it wedging on the last 2 bores... And, it made a special sound (which I can't explain) that only MTU series 4000 mainlines made when test barred at mid spec... I always thought of it as the sound of perfection, because that was exactly what it took to make it...
