Most powerful Diesel Engine in the WOLRD

Dont know if this is a repost, but I have not seen it on here.

Was researching a Cummins engine swap into my CUCV and somehow found this MONSTER (http://www.bath.ac.uk/~ccsshb/12cyl/) of an engine, Think it'll fit :rolleyes:

"Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm"

:eek2 That is some serious low-end torque. That is unbelievable!!! Good find :notworthy

I saw one in operation on The History Channel, it was mounted in a tanker. Each cylinder has an inspection room the engineer can enter to watch the operation.

How would you like to torque the heads??? They must put a D10 on the end of the torque wrench!!

[will_gurt]

That is ..is..is..... the biggest I have ever seen! One person comes to mind right now. Tim Allen from the TV show "Home Improvement" comes to mind.

I wonder what an oil change costs, or was that tanker for the motor :D
No seriously, can you imagine the maitnance bill on that.

I remember when I got my first pickup and changing the oil meant picking up 5 quarts of oil. Then I bought a dump truck and changing the oil meant picking up 6 gallons of oil. I wonder what this motor takes? Seven tanker trucks? :laugh Hmmmm, I wonder if they run synthetic or dino ;)


Dang D10, ya beat me to it!!!!!

will gurt "Tim Allen from the TV show "Home Improvement" comes to mind."Ugh ugh ugh. 1600 gallons of fuel per hour. :eek2
Wonder how often they do oil analysis? Rebuild expectations?

[544D10]

I wonder how they start it....I'm sure they just leave it running because these ships are only in port for a few hours but that initial start up and maintance too. Maybe a smaller diesel-electric or a long rope around the flywheel to a tug boat :yup

[xkvator]

the H.P. & Torque ratings were at 120 RPM, so what is idle RPM...10?

I found this pretty interesting - but then, I've had a few experiences with ships while loading Army equipment into them. I've toured many an engine room, and was always amazed.

FYI - Large diesels like this routinely have max speeds around 70 to 100 RPM, and while they're running, you can hear individual cylinders fire. Fuel lines to each cylinder run 2 to 3 inches in diameter. Individual pistons are the size of refrigerators, and there is usually a few extras strapped to the bulkheads in the engine room, as there is no way to get a new one down inside the ship, once the construction is complete. Ditto, the drive shafts - usually a spare section is suspended in the overhead, in case a section breaks. I've seen shafts like this in the three foot diameter range. As for starting, they usually use compressed air, and to reverse, they actually shut the engine off, and restart it in reverse. These things are direct drive, no clutches.

Great info, thanks.
Compressed air thats interesting, never would've guessed.

Was reviewing this morn, thought of a few other interesting points.

Since ships with large diesels normally operate one large screw for propulsion, they are pretty difficult to maneuver at low speeds and confined spaces. Many of these ships have bow thrusters, mounted crosswise in the bow to help with steering and maneuvering around a dock. In approaching an area, like a harborage, they will actually drag a tug boat, in reverse and usually thrusting against the ship to limit approach speeds, since the ship has a relatively high minimum speed, due to the direct drive. Approaching a dock, they shut down the big engine and let the tugs, along with the bow and possibly stern thrusters, do the work.

All bets are off here if ships have other forms of propulsion, like steerable screws, turbine engines, or other strange configurations. Cruise ships are mechanically much different from oil tankers.
