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.

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.

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!!

[@jackjackthompson5771]

You can really see why exporting this type of advanced machinery is so much more incredible than raw commodities like in south america where i live. Loading up ships with fruits, grains and oil, is quite basic compared to this advanced engineering. Bravo!

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.

[@justinlea2406]

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...

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!
