The most pwerful diesel in the world

guido · Jan 31, 2010

Hello,
The most powerful diesel in the world is a 2 cycle engine. It is also the most efficient.
Here are some pictures.
Not made in the U.S.A.!

What is engine to be used for???? How many cylinders ???

Goose · Jan 31, 2010

An instructor I had in diesel injection systems described a similar one on an oil rig in Saudi Arabia. All normal maintenance can be done while it's running, and it runs for years without ever stopping.

Impressive!

Looks like a 10 cylinder, I'd guess for a ship.

Dean · Jan 31, 2010

Thanks for the photos, Guido.

I've seen photos and read about these engines in the past. Available in 6 to 14 cylinder versions, these two stroke (Detroits forever) marine engines are made in Japan.

The design features a 38" bore and 98" stroke (111,143 CI/1820 L and 7780 HP per cylinder). The 14 cylinder turbocharged version produces 108,920 HP and 5,608,312 ft/lb of torque at 102 RPM. They are the most efficient prime movers built by man.

Wonder what they will do with a chip in them?

It is used on big tankers and container ships. Where I work, we take care of the governor for the engine. Governor weighs around 300lbs, with 200 ft.lb. of torque at the output shaft.

This seems to be a recurring thread around here, going back to AT LEAST 2004.

BIG sucker, though!
Sulzer thread from 2004

Dean · Jan 31, 2010

I've a bit more info as well as a few more photos of these engines in an email but do not know how to post it in the forum.

Dean · Jan 31, 2010

That's it.

Anyone making a chip yet?

Dean

agpilot · Jan 31, 2010

Thanks Bob. That's a good rundown of specs. ag

buickanddeere · Jan 31, 2010

The latest version have been souped for 120,000HP.

Dean · Jan 31, 2010

Must be the chip.

There was a show on Discovery about the Emma Maersk (largest container ship) with that engine. If one cylinder needs repair, they can take it apart and fix it without having to stop the engine. Incredible! I think they shut it off when loading and unloading. There's something like 6600 containers on those ships. Dave

Hello for those of you that are interested on the rest of the story.
Do a search on the most powerful diesel engine
in the world. All the info you want is in there.
Detroit Diesel 2 stroke/cycle thechnology is alive!
And more efficient then a 4 stroke/cycle engine!
Guido.

Hello Dean,
You think we can make this programmer work?
May have to come up with an adaptor?

JOCCO · Jan 31, 2010

Would make a good irrigation pump engine or tractor pulling engine!!! Imagine it throwing a rod or spinning a bearing and you being the one to repair it Ouch!! (may be when i was younger)

Richard G. · Jan 31, 2010

How do you crank it?

Coloken · Jan 31, 2010

I see at least two people here referred to it as a Detroit. Detroit is a 2 cycle diesel but this is not a Detroit. Sulzer?

JackE · Jan 31, 2010

Alot of compressed air.
Jack

Dean · Jan 31, 2010

We can probably retire if we can get another 1-2% efficiency out of it.

Dean

Dean · Jan 31, 2010

Of course.

The Detroit reference is simply a reference to the Detroit (formetly Winton) two cycle technology.

Dean

Dean · Jan 31, 2010

Apparently, at least some of the engines are cranked by electric motors, much like smaller engines.

One can see a geared flywheel along with what appears to be a starter drive in one of the photos.

Dean

JackE · Jan 31, 2010

That gear is for the turning motor. for slow turning of engine for maintenance. Engine is started by air, introduced to the cylinders from n airstart manifold.
Jack

guido · Jan 31, 2010

Hello TomH in PA,
The completed engine is the first 12 cylinder built. They are available up to 14 cylinder configuration, all inline. More efficient then my car engine! we should make one here in the states to beat it!
Guido

JackE · Jan 31, 2010

We have Colt-pielstick. They make some big engines. If an American company was going to go for it, it would be them.

Jerry/MT · Jan 31, 2010

Increasing scale helps improve the efficiency of all fluid devices. The boundary layers and and the leakages are proportionately less.

Hoss In ME · Jan 31, 2010

Chip my azz,put nitros and propane to it ! Hoss

CLTX · Jan 31, 2010

What's its fuel consumption? It probably has a 12" fuel line.

ChrisB · Jan 31, 2010

The part about the engine I can never figure out is how they are able to shut down individual cylinders for maintenance.

Must be some type of disconnect between the crank and the rod. I looked around but could never find enough info to explain why!

guido · Jan 31, 2010

Hello CLTX,
BSFC(BRAKE SPECIFIC FUEL CONSIMPTION)IS:
0.278 lb. per Hr. Per H.p.
BSFC at max efficiency is 0.260 Lb./Hr/Hp.
Your car 0.40 lb/Hr/Hp. Take or leave a few drops!
Thermal efficiency is more then 50%.
14 cyl engine at ecomy setting will consume 1660 gallons of heavy fuel per hour.
Guido.

TomH in PA · Jan 31, 2010

Fuel consumption is around 250 TONS per day.

That sounds about right, when I was in the Navy I estimated the cruiser I was on used about 100,000 gallons per day when we were at sea.

GordoSD · Jan 31, 2010

My F4 Phantom II with both burners lit burned 2 gals a second. That's 7200 gals in an hour.

I was one of those guys who launched those F-4's.
You are right,..they really burned up the JP-5.
What squadron were you in? We had VF111 and VF 51.

VF-92 CVA 64 VF-51 "Screaminf Eagles" Knew a lot of them. Tooter Teague, Blackjack Finley, Devil Houston.

Gordo

Wow, that's a lot. And how much gal can you burn up usually?

LeoinMI · Feb 1, 2010

Old Blackjack gave me a ride in the backseat of his F-4. Back then you could go to the paraloft and get a backseat License pretty qiuck. I got my one and only catapult shot and arresting gear landing from Blackjack. He gave me a pretty good ride over Cubie Point in the Phillipines. He wore a leather helment in the cockpit when he flew. Nice bunch of pilots all of them. Good memories.
