You thought your motor was big!
 

Check these out.
Avalible in 6 - 12cyl

12 cyl:
89,640 hp @ 100rpm
Bore: 38"
Stroke: 8'2"
2000 tons weight, crank alone weighs 300 tons!

Some serious power

aren't they incredible !!!!!!!!!!!!!!!!

what are they for?????????

How long do you think a bravo would last behind that?:D

that is comically large!!!!!!!!!

AWESOME!!!!!!!!!!!!!

If I am not mistaken they are made by Hyundai Heavy Industries for use on their ships. There was show on Discovery or TLC recently that was dedicated to the companies evolution. Really really cool if you can catch the show.

Ships or electrical plants
Although turbines are now the norm

I would like to see that thing on a dyno pull :)

Hey Ray how's the 47 Project going??? engines ??? This engine might fit in there from the bilge I saw!!!!

I saw some of that show.
Did you see how big that shipyard was ? They do everything from actually making the steel from ore to the final ship.

we just pulled an engine about half that size out of one of our dredges. we blew it up due to an oil failure somewhere. they aren't meant to be swapped out often. that one had been in the dredge for 40 years.

at 100 rpm peak hp, going to need some serious pitch on the prop.

How Did They Machine The Crank, I Would Like To See The Lath That Turned It...

Jeff

I was on a cruise many years ago. I put a written request into the engineering and they took me on a tour of the ships engineering spaces. The engine room was absolutely incredible! Theirs was a bit smaller than the one pictured above-it was only 5 cylinders. Even so, the engine was 3 decks high. It turned so slowly that it looked like you could just reach out and stop the crank with your bare hand. The pistons were like 6' tall. They kept a spare one in the engine room. There was a overhead bridge crane for installing it! There were windows so that you could look through a porthole and see the crank spinning inside the engine! There were also doors that could be removed so a person could get INTO the crank case! You could feel each and every piston fire. The engine turned a constant rpm. I think that one was turning 150rpm. When a piston fired you could feel it through the entire ship. Consider the amount of mass in a ship that needs to resonate and you'll get an idea. They would speed the boat up or reverse it by changing the pitch of the props. The engine consumed some 55 gallons per mile of diesel fuel.

German design, Japanese labour, American paint...............

The Wartsila NSD (Sulzer) RTA96-C two-stroke diesel engine is the most
powerful and most efficient piston prime-mover in the world today.
Bore - just under 3'2" (965mm).
Stroke - just over 8'2" (2489mm).

Available in 6 through 12 cylinder versions (all inline).
Engine weight exceeds 2000 tons in the 12 cylinder version (the
crankshaft alone exceeds 300 tons).

Point of maximum continuous power is 89,640 HP (66,844kW) at 100RPM
with the 12 cylinder version.
Point of maximum fuel economy is 53,244 HP (37,704kW) at 90 RPM.

The 12-cylinder engine exceeded 100,000 horsepower during overspeed
testing (all of 101.5 RPM!) while under test at Japan's Diesel Union
works (who built the first engines and from who these pictures are
taken).

Fuel consumption at maximum power is 0.278 lbs/HP/hour (BSFC).
Fuel consumption at maximum economy is 0.260 lbs/HP/hour.

At maximum economy the Sulzer engine exceeds 50% thermal efficiency
i.e. more than 50% of the fuel going into the engine is converted to
power).
For comparison, consider that automotive and small aircraft
spark-ignition engines have British Standard Fuel Consumption figures iin
the 0.40-0.60 lbs/HP/hour range and 25-30% thermal efficiency.

Even at its most efficient power setting, the Sulzer 12 cylinder
consumes nearly 1,660 gallons of heavy fuel oil an hour.

Just for grins......
 

100,000 hp @ 101.5 rpm = 5,172,413.7 ft-lbs of torque.

Yes - 5.17 MILLION ft-lbs. :crazy:

Umm......could ya imagine that thing throwin a rod....:eek: :eek:

Or how about making the decision to run Synthetic or petro oil....:crazy:

It's like looking at porno for boat's,It's so BIG.:eek: :eek: :eek:

I love the ladders in the crankcase next to the crank throws. Wonder how fast you could turn it on Nitrous?? Figure a tanker truck of nitrous would be good for a ten second pull:D

Hey do any of you remember what the show was called on TLC or Discovery that talked about it?

Thanks

WHIPPLE IT !!!!!!!:D :D :D

haha! need a whipple, procharger, and turbo all blowing on that thing

They actually do turbo charge some of them. I did a search on ship building and found alot of info on some of that stuff. unfortunatly I didn't save any of the links . They shouldn't too hard to find.
I do remember a picture of a turbo the size of an adult. I will see if I can find it.

Saw some engines similar to those in Texas that were used to pump oil up the pipelines. Had like three foot bores and four to six foot strokes. There were inlines and vee's.

They were supercharged by additional pistons that ran on the same throws as the pistons. Ran for years.

You could feel the ground, concrete, shake and throb from them.

Saw them pull a cylinder to replace a rod bearing. Looked like a normal babbit bearing only REAL BIG. They turned the crank throw too. Had a machine that was self propelled and ran around the journal. Took like all day to cut.

Was very interesting. Back around 1967 or so. South Texas someplace. Near Beeville, Petus [spelling] maybe.

i know that company,visited their web page before
cool engines..

How many quarts of oil does the pan hold?

Just went on go-fast.com and calculted my top speed with one of those bad boys in my boat at 695MPH Passed the sound barrier. What's the website to put in my order.:D:D:D

Ok, how long are the rods?? What is the rod ratio for that beast? and have they built any with short rods?? :)
