I didn't read the pages but there is not a physics based limit to the size of a diesel engine so I assume it is diesel.

Gasoline engines will eventually have detonation as you go to larger and larger piston diameters (if you try to keep the same compression ratio).

Can a guy run an Alaskan MkIII with that?

Have you guys seen this?

I keep looking at these pictures and wondering if it's real. I did some searches and it appears to be real but unbelievable.

How do you think they start it? A motor (maybe 50 horse?) is at the end of the crankshaft. Could it?

I have stood next to some huge engines on that order, but not that big. The neighbor is a foreman for ANR pipline and I have been in with him to one of the Natural Gas Pumping stations when it had an engine down. Monstrous. They are just like other internal combustion engines only HUGE

That would lend a new meaning to the term "Pony" engine.  It would take at least a "Belgian" or maybe even "Percheron" engine to start that rascal.   Perhaps they would even be used in teams, eh? :D

I'm glad I don't have to change the oil in that  ;). Can you imagine filling it a quart at a time :o

It was funny to see those huge natural gas pumping engines had normal everyday spark plugs.

I keep thinking about things like wrenches. How would you torque those head bolts? How would you even get the nuts on and finger tight?

And what about the muffler? Can you imagine the kaboom over a three foot diameter piston with a 111,143 cubic inch displacement? 7780 HP per cylinder?  :o :o :o :o :o :o :o :o :o :o :o :o :o :o :o :o

Maybe I can get over to ANR and Tom will let me take pictures.

The muffler looks like a large smoke stack. The radiator is a large wall out side

 It's certainly BIGGER than the 16 cylinder I saw at Cat  :o :o :o.

A D500, Ed :D    It would move mountains....maybe mountain ranges. :D :D

They started some large engines with air pressure right into the cylenders 1 at a time in sequence to get the engine rolling over and up to speed and then they could fire it up.

As far as the ANR pipeline gas pumping stations the engines there are rolled over with natural gas pressure until they are up to speed to fire them up.

Wow!  Reckon how big of a headsaw you could twirl with that baby. :o

I had a motor just like that in my weed eater but kept breaking the starter rope so had to replace it with something smaller.

Can you imagine all the head scratching that took place when they were designing that monster? Besides for the sideways force exhibited by the connecting rod, what other accomodations did they have to make? Even just figuring out how much the various pieces would expand and contract with varying temperatures is enough to make my head spin.

Probably, archaeologist will someday look at one of these engines the same way we look at the pyramids and wonder how we did it.  :D

Imagine the engine mounts needed for a 2300 ton engine :-D

I bet the 102 rpms keep it down to a low rumble sort of vibration.

That is the same exact engine that I have in my chainsaw. Im always sore at the end of a long day sawing.

That sure would make a nice little trolling motor.  Probably would get me one but the pond is just a little too small.  Would like to hear it crank up though.  Wonder how big the prop is for that thing?  Sure would hate to be the one that has to pull the cord.

Naw, you can't use it on your Alaskan mill, it breaks the log when you set it down.
Marine diesels have a long history, in WWII the bulk of Germany's navy used them, includin' the Bismark and Tripitz. The letters SS meant steam ship, MS meant motor ship.
