100,000 hp *you think I'm kidding*
 
12 cylinders of course and no it's not the newest dodge viper...

displacement owns

redlining it at just a hair over 100RPM LOLOL!

how loud do you think that bad boy is?

Does it have V-TEC? :D

That's wild...

I love that picture of the guy's head peeking over the crankshaft journal.

Wonder what it's for? Ship, or maybe a generator?

Amazing.... 1,333,722 cubic inch displacement. If I've got the math right, that's a 21900 liter engine! That's 10,000 Proteges!

How little you know about turbine efficiency. There is no way you could ever get that kind of efficiency (0.260lb/hp.hr BSFC) out of a turbine. Turbines primary advantage is power-to-weight and size.

The military destroyers that use turbines for speed use regular diesel engines for cruising. The same with the Atlantic-crossing-record boats. I think the typical turbine is closer to 0.60lb/hp.hr BSFC (or higher), with an efficiency of 25-28% for constant speed applications, and lower in mobile applications (compared with over 50% for this diesel).

Another disadvantage of turbines is the speed at which they change speed. Not so much a factor in big ships, but turbines greatly prefer constant speed applications.

As an example of the advantages of even a gas engine over a turbine, look at the Orenda aviation engine http://www.mrrpm.com/

So, is that the Curtiss-Wright (formerly John Deere) rotary (the big one)?

BTW - that engine is the COOLEST.

Kinda looks like a bunch of real little people running around on a regular-sized motor (if there was suh a thing as a straight-12 - is there?)

The New SD90MAC Locomotive

The Union Pacific Railroad has now taken delivery of seven new SD90MACs, currently designated for intermodal service between Los Angeles and Chicago. The new 6,000 horsepower SD90MAC delivers it all: power, reliability and performance. From its highly reliable, fuel efficient 16-cylinder H-Engine, to its WhisperCabTM and FIRE cab electronics, the SD90MAC has established itself as the 21st century advanced technology locomotive.

Nice!! Think my firewall can me moved back a foot or two? ;)

I'm pretty sure Caterpillar makes straight 12 engines, too, for generators. My dad would know for sure. He works for them.

And wouldn't it be great if there actually WERE little tiny mechanics? You could have them fix problems while you were driving!

Caterpillar makes straight 8's, but any engine with more cylinders than that is a V (V-12, V-16). And that locomotive engine is not a straight 16 (you can count 8 valve covers on the side shown.

So, did anyone notice that there are ladders that lead down into the bottom of the engine (look on the walls of the crankcase).

correct, the Prime-Mover in the SD90MAC-H is a 16V265H: turbocharged 16 cylinder, 45 degree V, that makes 6300HP at 1000RPM.

You're right; I checked, and Cat makes everything over 8-cyl as a V. But one of their German affiliates (and dammit, I forgot the name...It's initials...M something something?) makes inline 12s.

I think you are thinking of MAK

But even their largest in-line is an 8 cylinder... the big beasties are Vs.
