U-Boat Engine Start in the Kiel-Wik Engine Museum 

Ah ha. Thanks for letting us know. Concealing down votes is not cool. And they don't let me use the same term as you did, or I get an "error in posting" message.

RU-vid marked your Comments as Spam for some Reason. I don't get notified of them, so I check the Spam Filter every now and then only. That may also explain the Error Notification, but IIRC "Spam" and blacklisted Comments just disappear silently unless they get manually approved. And you can get a Browser Add-On to still be able to see Dislikes, at least until RU-vid removes the Dislike Count from the API. Dunno if they keep it in RU-vid Studio, if they don't I can't maintain these Dislike Comments anymore either.

Did that myself many Times, but mostly with Deutz Engines, in the Lübeck-Travemünde Seaman School, and on the Museum Ship Cap San Diego. The Captions could be bettet though, I edited this Video with Windows Movie Maker, but I use a better Program (Movavi Video Editor) since about a Year. It allows more Customisation in the Captions; check out my latest Videos for Comparison, they look much better.

*With quite a bit of Editing* Peter Horter (the Man in the Video) has a Habit of explaining Things very, very slowly, making it hard to follow him. I turned over 15 Minutes into just about 4. In my Seaman School, we have a similar Engine (but a Deutz instead of a MWM, and it was originally designed for small Shunting Locomotives), and doing the exact same Procedure for starting takes 2-3 Minutes. Plus sorry for the late Reply; I was a bit busy over the Holidays.

But don’t know how to win wars

@@cylersmiley5259 bit like the US then

I eventually replaced the Diesel Sound with a better one back when I played Silent Hunter many Years ago. They actually got a few Things wrong; e.g. did no U-Boat have reversible Engines so they always had to use the Electric Motors for going astern. The Music is an Organ Cover from the "Das Boot" Soundtrack.

Ah, that is very interesting I did not know that! I imagine they did not wish to reverse that often due to that reason! Thank you. cheers

@@Genius_at_Work the G.W. supercharged engines were reversible while the turbo krupp engines had the 2nd cam position for better turbo performance, with stock profile used in situatioms where back pressure from swaying in the sea or snorkeling created too much variance in turbo performance. type 2s werent reversible most 7s n 9s were

@@rileykirk11 That's some excellent Information there; the only Engines I know some Details about are the MWM RS 34 S in this Video here and the MAN M6V 40/46 (respectively M9V) that I mentioned too. I'm planning to visit U2540 in Bremerhaven later this Year to make a Video similar to the Type VII C Engine Room one that I recorded on U995 in Laboe. Even though the Type XXI originally had The MAN M6V, these Things will be nice to tell when talking about the badly engineered Snorkel Installation on the Type XXI. Plus the Engines were adapted for higher Charge Air Pressures by a larger Valve Overlap (English Translation?) compared to the Type VII. But I've got another two U-Boa Videos coming up long before the U2540 one; about SM U1 from 1906 in the Deutsches Museum Munich and about the Junkers Free Piston Air Compressor used on all WW2 U-Boats.

@@Genius_at_Work hell yea. how was the 21s snorkel bad? never heard about that before. ive gotten alot of what i know from the tyoe 7 manual on google. wish there was more info like that for the type 9 21 etc...and yes the 6 cyl in the 21 was turbo only with two cam positions foward only, just made more power than the m6v in the 7. greater reliance on boost in the 21 meant the use of 2 cam positions is necessary while early 7 and 9s with the turbo were reversible and had iffy rough sea performance. some had the twin forward cam. now that you mentiom it i seem to recall info about constant pressure changes during 21 operation snorkeling due to stealthiness of a low snorkel taking priority and high boost turbo engines sucked multiple times the air of earlier supercharged design. ever thought of touring the vessiko?

Not so much. Modern Four Stroke Marine Diesels still are OHV Engines, although the Push Rods and Rocker Arms are under Covers today, so they can be lubricated by the Forced Lubrication System instead of a Mechanic coming by with an Oil Can every two Hours. This Engine here already has four Valves per Cylinder, unlike the larger MAN Engines of Type VII and IX Submarines. The most importantg Difference to modern Engines is, that this one is naturally aspirated while modern Engines typically are turbocharged to 2-3 bar. OFC that requires a stronger Structure, which often requires better Metallurgy. Other than that, the Differences mostly are in Details such as higher Fuel Injection Pressure. Another one is that today, Engines of this Size are started by Starting Air Motors or Electric Starters, instead of blowing Compressed Air directly into the Cylinders.

Built in 1944, but designed in the 1930ies. Engines like that were built from the 1920ies to the 1970ies.

That's because it's running without Load and a because it's naturally aspirated Engine. Modern turbocharged Marine Diesels are insanely loud, even when running "Idle" like this Engine here.

I've also got two Videos showing the Engine Rooms in Museum Submarines, where you can see the Electric Motors: U 995 Type VII C in Laboe: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w5ms4UdXwVQ.html Soviet Diesel-Electric Submarine in Hamburg. This Video goes into a bit more Technical Details and has much better Quality: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gymrTU4XkgM.html The U 2540 Type XXI in Bremerhaven is on my Bucket List as well, and I'm considering to make a new Video of U 995 because the one above doesn't really hold up to my Quality Standard anymore.

It was built in 1944 for a Type XXIII Submarine but the War ended before it could be fitted to one. After the War, it was used as Emergency Generator for about 40 Years.

Weil der ganze Kanal auf Englisch ist, und nur etwa 1/4 meiner Aufrufe aus dem Deutschsprachigen Raum stammt.

It's from a Type XXIII. The Type VII C had much larger MAN M6V 40/46 Engines.

U 995 had much larger MAN Engines, as Type VII. This is from a very small Type XXIII, although it never was fitted onto a Submarine and salvaged after the War to be used as Emergency Generator. Hence it's in such good Condition.

The Engine actually is one of the quietest Marine Diesels I ever encountered, particulary because it isn't turbocharged

If you don't care where it was fitted, it just is a bog standard Medium Speed Four Stroke Diesel from back then. The most special Thing about it is having four Valves per Cylinder. It's just a normal Engine that happened to be used on Submarines and the Bismarck Class Battleships. That Just makes it significantly more interesting to many People. My former Seaman School has a comparable Engine from Deutz, and you could literally interchange them. The Fact that it is still running today isn't special either, as it spent all it's Life as Emergency Generator, thus ramping up almost no Running Hours at all.
