One for shutter.. ship engines

Just watching mighty ships on Quest..
It's about the danish ship absalon. Apparently each cylinder in the engine can run independently. If one cylinder develops a fault, it can be stopped while the others keep running.
Any idea how thats done? - If our car engine has a fault you can't stop a cylinder running so I'm wondering how ship engines do it. Are they linked through a differential or something? - EG lots of little engines linked up to make a big one?
I need a new signature... i'm bored of the old one!

Anyone else know? - I'm really curious as to how you can stop a cylinder of an engine from running..

Re: One for shutter.. ship engines

I was an engineer in the merchant navy for 25 years, and while a fuel pump on a particular cylinder could be "lifted" so it didn't supply fuel to that cylinder, an engine could be run for a short period on one less cylinder. But what you have suggested AFAIK is not possible.
Did you hear correctly? A quick google states that the Absolon class is TWIN- engined and as such if one engine develops a fault it can be shut down and the ship run on the other engine Smiley

Re: One for shutter.. ship engines

Doing some early morning research via google...
Wiki entry on the Danish Ship Absalon...  http://en.wikipedia.org/wiki/HDMS_Absalon_%28L16%29
From that page, I went to the "spec" of the ship and followed the link MTU

Interesting this company make the engines for our trains.... (scroll down to "Diesel engines" ) http://en.wikipedia.org/wiki/MTU_Friedrichshafen
Here is a pic of one of the engines....http://en.wikipedia.org/wiki/File:MTU_croatiaboatshow.jpg

Will this fit under the bonnet of my Toyota Avensis? http://www.gizmag.com/go/3263/
Experience; is something you gain, just after you needed it most.

When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.

The rest of that link is quite interesting as well.

Re: One for shutter.. ship engines

I think the scale of the thing against the guy standing on the walkway on the engine is rather telling.
In the write up, much is made of the crosshead piston head arrangement. I'm not sure this is new. I think (and willingly stand to be corrected) that Titanic's engines used a similar arrangement.
