Got smoked by a Powerstroke -in his dreams

What is lugging?

Just wonderin' guy's, what is the largest diesel engine produced? And what is it used for? I was rummaging around in a boneyard yesterday, and came across a con-rod that was about 5' tall. Got me thinkin... .

Thanks,
 
I posted a couple of months ago about a ship I boarded in Savannah. 40,000 hp, 10 cylinder with twin turbos about 8 feet in diameter. Burned about 1 ton of fuel (bunker C) per hour underway. Valves the size of soccer balls. Crankshaft about 24 inches in diameter with fuel lines for the injectors about 3 to 4 inches in diameter. The cylinders bolted together on the horizontal so each one was an independant engine rated at 4000 hp. Total deal was probably 50 feet long and 30 feet tall. Now that's a diesel. Max RPMs was 300. Air start with a flywheel that weighed in at about 34,000 lbs.
 
The biggest they use in a Locomotive is a 20 Cylinder. But its only about 40 feet long. My guess would be some of the ship engines but that is not my field
 
Marine engines by far are the biggest, like Alan said, 3 stories high and slow running.
The biggest I've been in contact with are the Cat 3600 series. Only about 11. 8" bore/stroke and around 4500 Hp at 1000 Rpm.

J-eh
 
EMD Locomotives uses EMD engines which are there own design and made in La Grange Ill, GE Locomotives use there own engines but they are based on a German design and made in PA. They are called "FDL"'s.
The most powerful EMD is a 16 cylinder, 4 cycle twin turbo that puts out 6,340hp at about 930RPM, there biggest engine size wise is a 20 cylinder 2 cycle turbo that puts out 5000hp. GE's biggest engine is a 16 cylinder Twin Turbo 4 cycle that puts out 6000hp also. Morrison Knudsen made some Locomotives that used a CAT 5000hp engine but onle 6 were made and thats it. EMD engines are also used in small ships, Tug boats and as Oil Rig and municipal power plant generators
 
Okay, just for the fun of it, what's the smallest diesel? I've seen people with these gas-powered scooters, and I've thought, "They'd get more mileage on that little tank if was a diesel. "
I'm wondering if anyone makes a diesel powered model airplane engine or anything like that?

EMDDIESEL,

The GE locomotive engine design was purchased from Cooper-Bessemer, located in Grove City, PA. The Cooper-Bessemer designation for the engine was the FVBL. Cooper had built the engine for years with GE being its largest customer. When Cooper decided to phase the engine out, GE bought the drawings, patterns and production rights.

The Sulzer RTA96C 14-cylinder 2-cycle marine diesel has a 960mm bore, a 2500mm stroke and produces 108,920 BHP @ 102 RPM. May or may not be the largest, but it's right up there!

andy, the smallest ones that i have noticed are HATZ and YANMAR both are used in generaters seem to be quite economical but quite expensive as compared to similar gasser.

Check out www2. towerhobbies.com/cgi-bin/wti0001p. pgm?Q=1&I=LXC007&P=7 for the smallest diesels. They are for model airplanes and 1/10th scale trucks. They will fit in the palm of your hand.

This conversion head fits a . 40 engine.

I spent a little time onboard USS John F. Kennedy and we were DFM powered. I don't think we had "engines" per se, but rather boilers. We had 8 I believe, 2 main machinery rooms with 4 boilers each. Or maybe 4 main machinery rooms with 2 each (I fly airplanes off the deck - what do I know?). In any event, these diesel powered plants drove the "boat" (98,000 tons) at speeds of 30 knots +, powered 4 steam catapults, 4 arresting gear engines, provided water for 5500 people plus the water for the boilers, electrical power for the entire ship (lights, radios, radars, ovens etc) etc. Does this count?
 
Joel, How big were the planes you flew off the deck? Were they the . 40 engine equippted variety that Semi Automatic mentioned #ad


Seriously though, I've only witnessed one takeoff from a deck... very impressive and loud!!!! It's gotta be a rush to feel taht acceleration.
 
joel, the JFK use's Fairbanks Morse Opposed piston Diesel engine's to generate emergency power. the rest of the ship is powered by steam. i worked on Fairbanks Morse Engines
when i was station on the YTB'S & YTM'S tugs at the Norfolk Navy Ship Yard in Portsmouth,VA.

Hmmmm, I think Bill K. makes a TC and VB for that 108,000 HP job???
What's Bill's # ?

Jeff - 56,000 pounds normal launching weight. No, I don't think that . 40 engine would cut it at the end of the cat stroke.

vince - yes, the ship is powered by steam, but it's a diesel powerplant that generates the steam. The question didn't say it had to be a piston diesel engine, right??
 
And only 5,608,312 ft-lbs of torque for the sulzer. No ETH clutch for this one.

Okay, I have to ask. Is it really a diesel if it burns diesel fuel, but the fuel fires a boiler?



For that matter if it burns alcohol, but "diesels" without a spark ignition, isn't it really a diesel, even if it doesn't burn 'diesel' fuel? That would make the smallest diesel I've ever seen, an . 010 displacement model airplane engine



Strictly speaking, I thought it had to be a compression ignition engine to be a diesel, but I'm not the expert here. It's our forum and I'll subscribe to any definition we can agree on.



Just thought I'd stir the pot,

I forget the name of the company but the smallest R/C diesel engine avail. is . 129 CID conversion, that's about a 9/16ths inch stroke by 9/16ths inch bore, about 1-eiigth of a cubic inch. Actually the glow powered engines are very similar in operation to a diesel starting on the glow plug cycle. As far as biggest, I though there was a mention of an engine Allis-Chalmers made decades ago for a power plant that the displacement was measured in CUBIC FEET..... Piston was 5 or 6 feet in diameter, and the stroke was about the same..... but only ran a few hundered RPM. :)

DENNY... ... ... ... ... ... .....
 
Isn't that a beautiful sight?... um site :eek:



Big Allis in NYC is smaller? Bigger? Does anyone know?



Dr. Evil,



You seem to make a distinction between the engine you mention and a garden variety model airplane engine. What is the difference?



I always thought that the 'glowplug' style engines were 2 stroke, alcohol burning, diesels. Am I wrong?
