Swedish Torpedo boat from the 50s starting her 3X1650Hp diesels. Massive sound;) 

I like the few first seconds, she sounds really mad;)

Real nasty. I want one, doesn’t even need to have the boat attached

Isotta Fraschini motors. V16s unless I misremember. Absolutely insane. Steyr Puch also make some magnificent pieces. That thing there, deplacing 50 tons, can sling around its weight in the archipelago at well over 45 knots all day.

@@Sakhmeov They're W-18s. Three banks of 6 cylinders each.

Oh yes 👌🏻🤣

Actually, they are not. They based italian Isotta Francini petrol aircraft engines with four valves per cyl. European havent done lot of two stroke diesels besides Junckers Jumo and british Napier Deltic(which are based to Junkers license in beginning) opposite piston engines. And imo as you can see also in here, four stroke turbo diesel rumble is so much more beautiful than two stroke diesel screaming.

@@teppotulppu1603 bruh 🤯

@@teppotulppu1603 If that’s a “nasty class” they are Napier Deltics.

I know nothing about engines I'm here cuz it sounds cool

@@teppotulppu1603There we’re many more two stroke diesels in Europe than most Americans would recon. The world isn’t revolving around Detroit diesels.

Diesels warming up sound like a gas engine? Wow.

Almost, actually 4T 56L W18 1650hp

😂

It's a 2 cycle.

@@MrSTOUT73 2 cycle diesels have cams for the exhaust and fuel injectors. Google is your friend.

@@vector6977 The Deltic was valveless, though.

Nix Napier Deltic. The 3 W18 engines are original south bavarian (italy) motors from CRM s.r.l. based on Isotta Fraschini.

From what I could tell the W18 is a four stroke.

You are right, the original engines were gas engines but they're now upgraded to diesels.

The Napier 'Deltic' engines were not a Y configuration but a Delta cylinder configuration, ie , with a crankshaft on each of the 3 corners of the cylinder banks . The 2 stroke diesel engines being of an Aluminium construction gave a tremendous power to weight ratio over the normal fast patrol boat engines of that era and were designed to be easily exchanged should an engine failure arise , the exchanged engine then being repaired at a land based facility . We used the Napier Deltic engines over here in the UK in the locomotive of the same name , these were used on the East coast rail route from London to Edinburgh. 21 of these locos were built and served the service well for over 20 years , six of the class are preserved and run regularly on preserved railways and main line 'enthusiast special' workings to this day .Cheers .

+Mike sullivan The Deltic were used in the PTF "Nasty" class and were turned over to the Philippine Navy due to they having an oven big enough to swell the block to change cylinder's to the engine. I saw the last one at Little Creek Amphib. Base in VA. back in 1978 I was an EN2 US Navy assigned to Special Boat 21.

+Michael Galey ,True enough about the ''Nasty' Class ' Michael , I beleive they were made in Norway for a few of the worlds navy's as a fast patrol boat , the Royal Navy here in the UK used the Deltic engines in another type of fast patrol boat and the RAF had some for Air Sea Rescue purposes . I read somewhere that the US Nasty class boats did some sterling work in the Vietnam war , and were used for recce misssions and search and recovery ops as well as Marine support work . The Napier Deltic engines were high maintenance cost items , but on the Railway We had the facillity at Doncaster Railway Workshops to turn the locos round quickly if failureoccoured , with both engine units replaced in a day on many occassions, recon engines being available from their own rebuild facillity .Mny of the Deltic class loco's covered over 4 million miles in their short 20 year lives !

@@michaelgaley9532 In 77 there were 4 or 5 of them layed up on shore at Little Creek right behind that titty bar with "Big Shug". A damn crime they weren't saved and donated to museums. I read they were all scrapped in the 80's.

CRM motori

Adventure Journal Governor is , so called, hunting

And engines are cold

Deltics just lope a bit when they're cold. Similar to a classic car, they just don't burn fuel as easily or efficiently when cold, due to being diesel.

Not 1-2-3 pause 1-2-3 pause but Brrräärrr Brrräärrr Brrräärrr.

those are fuel injected diesels. as it warms up they smooth out with idle. When cold starting diesels have alot of blow by (smoke) because to much fuel is barely being lit as it blows thru, as temp changes and moisture in the fuel lines disappears with it and idle sounds somewhat normal. Cold the oil is thick, inside the engine theres resistance.

More fuel....

Your almost right. We have 3 CRM 18D/SS engines converted to diesel. 18cyl 57/litre each. So that is 54 even bigger cylinders;)

Interesting point you make. My father was a Chief Petty Officer (RN) engine room artificer on MTBs in WWII in the Mediterranean. He used to tell of needing repairs to one of the V12 Packard engine in his boat and calling in to a US Naval base in Sicily, I think it was. Called in to see if he could get a replacement for a cracked manifold, but the Americans told him they couldn't supply spare parts...but could give him an entire new engine. They just lifted out the old engine and replaced it with the new one in an hour or two. He always remembered the "can-do" attitude of the USN compared with the reams of regulation required by the RN. My dad said it was the only time they ever got an engine with complete set of tools, spares and operating manual, which he kept. My younger brother, just turned 75, still has the manual for that V12 Packard.

The Americans used 3 Packard gas v12 engines.. But these have a few problems. At full speed they burn 200 gallons of high octane av gas and hour. Av gas is expensive..very expensive. Av gas is highly inflamable.. so getting hit when you are carrying 800 gallons of high octane petrol is very dangerous. So most countries opted for diesel engines. The fuel is safe...and the the engines can be tuned to run on low grade marine fuel. Diesel engine are more fuel efficient so the range improves dramatically. And finally.. the old napire diesel engines had no brains in them( electronics) so emp will do nothing to them.. The other advantage is you could inject diesel into the exhaust and make smoke.. and old defence but still works..

@@richardoakley8800 any gas will go up if hit with tracers.

Sorry, but they're not packard. CRM diesels.

true

Guess again

Nope. Isotta Fraschini power.

Vegard Kaspersen Dillerud id love to know where u got that information from

Long live the V8 you are never late in a V8.

cidertom it’s three V6 blocks combined to form each engine. www.google.com/amp/s/oldmachinepress.com/2019/04/05/isotta-fraschini-w-18-aircraft-and-marine-engines/amp/

Eh... No.

Nothing detriot was used in miltary boats

Gardner engines when cold can hunt

Detroits don’t sound like that... www.google.com/amp/s/oldmachinepress.com/2019/04/05/isotta-fraschini-w-18-aircraft-and-marine-engines/amp/
