[Video] Why does it take so long for this Class 50 to start up when cold? (www.youtube.com)

It seems to take nearly 10 minutes to get started. What's actually happening? Are the pistons literally unable to move in the cylinders until the engine is warm enough?

Someone in the youtube comments said so about an old diesel sounding like crap when only 2 out of 16 are firing. Must be something to it then. Maybe they can set it up so that its always a different 2 cylinders that do the heavy lifting (to even out the wear) while the others just sit there generating heat through friction. These engines must be massive and you can't exactly roll them into a garage to loop the oil every time you need to start them up.
