I was highly impressed with a documentary on the television yesterday evening. The diesel lump in question was the 'Deltic' used in state of the art locomotives built in the early sixties.
It seems the Deltic had two cylinders sharing the same bore. These were set in the shape of a triangle giving 6 cylinders. Six of this configuration was then joined together giving a 36 cylinder (I think) diesel engine, taking up a relatively small space.
As far as I can see the Deltic diesel was only produced for a couple of years. Not sure why.

As an ex-spotty nerdy trainspotter in my youth ;D I remember the Deltic, I never knew much about the technicalities, but I do remember that they were bloody huge things, and very imposing.

Faster than what went before.

Thanks, Al. Yep. The animation explains how it works far better than I can. That is one big hunk of derv on the back of that lorry.

I think that should be two pistons sharing the same cylinder.

I still cannot get my head around it, but any 18 cylinder lump with 18 superchargers gets my vote 8)

Possible to fit under the bonnet of an Omega or simply too large? ;D

Do you think that engine in the last clip would pass an emissions test?

Yes - judging by that last clip, Euro 6 emissions compliance might have been a problem. :-\
Also used in boats. Trains and boats - both vehicles in which the combustion of diseasel is acceptable. :y

Do you think that engine in the last clip would pass an emissions test?
Certainly would with a VW tester.

Yes, that would be the software hack that shuts down both Deltics and plays the characteristic exhaust note through a very large P.A. system until out of sight. ;)
Oh, and they'd have to find a way of making it necessary for the whole front of the loco to come off to service the engine. ::)

Woman with the kid in the pushchair wasn,t very impressed, (clip 3) ;D

Wait till that Mr dtm read this thread his post.be longer than any of dbg's. :)

Yes, the sound of a Deltic at full power is a dream, even for a hardened steam engine enthusiast as myself.

and to prove they are still loved and exist here are five of them together (there is one more in preservation):

The Mallard is just gorgeous Lizzie. They clearly understood the importance of aerodynamics even way back in 1938. :y :-* :-* :-* :-*
