World largest engine

So what sort of ship does it power oil tankers? they must be some size to have an engine that large.

First was the Emma's maserk (sp) 30kn capable cargo ships.

Found a pic of her she's huge amazes me how they build ships that size too.

Possibly in bits - look up the current UK aircraft carrier builds.

It may make more HP then a steam engine from over 100 years ago but I'd like to see the torque curve comparison of the 2 and the difference in the 2 engines as far as displacement goes.

Steam ALWAYS make more torque because of simple physics, water can not be compressed.

Wow, look at the size of the flywheel, I bet its a twat of a job pushing the clutch pedal down, lol

made me laugh

ships use a "Dry" steam... wrap your head around that one

I've got a book on steam properties. Simple enough in principle but a complete pain to simulate with it as the main fluid as it's a real gas until you hit the dew point.

Good article on Diesel/Electric vs. Steam

That article doesn't mention drive wheel diameter unless I missed it. That goes into figuring the tractive effort for both steam or diesel engines. The larger diameter the more wheel surface contacts the rail head which helps the engines dig in.

Case in point look at the wheels on an EMD SD9043MAC which are much larger diameter then say a GE 4400ACE engine. Both have about 4400hp but the EMD engine will pull where as the GE engine will just spin it's wheels. I know, I've ran both! LOL!
