I can't remember. Think a huge boat but still can't remember for sure.

my 400ex i decided to make it a hybrid:p

itrs used for a boat the was made in finland(i think) and it has the record for being the biggest and longest boat in the world.

I want to here the beast run :macho

[muddy400EX]

ive actually seen this posted on here b4. pretty crazy

[wilkin250r]

It's been posted a couple times, let my try this from memory.

It's a 2-stroke diesel engine, that I know. If I remember, the stroke is about half again as tall as a man, so it's like 9 or 10 foot stroke. It comes in an 8, 10,or 12 cylinder design. Max horsepower is 10k horsepower, at a little over 100rpm.

Anybody willing to double-check me?

ive seen this before as well as on here...i believe your pretty close, but i think the rpms are actually somewhere in the range of about 30 rpms

1,660 gallons/per hour = 39.5 barrels of crude oil/used per hour = $2,844 These figures are worked out from the basis of crude oil @ $72 a barrel*

$2,844 every hour the engine runs or 27.6 gallons which is $46.00 every minute or 76 cents a second ! That is of course if the ship owners buy oil at trade price...if not then these figures are the absolute minimum

from a website..

"These engines are built in 6, 8, 10, 12 and 14 cylinder configurations. All the engines are straight or "inline". The diameter of each cylinder is 3 foot 2 inches with a stroke of 8 foot 2 inches. The 12 cylinder version weighs in at 2000 metric tons and delivers 90,000 hp at 100 revs per minute, with best fuel economy at 53,244 hp at 90 rpm.

When I mention economy, the 14 cylinder engine for example with a displacement of 25,480 liters ( 1.56 million cubic inches ) burns up 1,660 gallons of crude oil every hour, now that is what I call good economy !"

I was way off on the horsepower, but the rest I was pretty close :)

ya...thats some insane horse power tho...

but i guess that it is necessary to move a ship thats 458.5 meters long...

I should have thought about it for a second or so. 10k horspower isn't NEARLY enough to move a behemoth like that.

[ben300]

Ya, I would love to see a boat that size in person. Just the thought odf the shear size of that thing truly amazes me.

That motor is crazy though. Its amazing that even after 1000 hours of use, the internal diameter of the cylinders only changes abot 0.03 millimeters.

[Ruby Soho]

i love big engines like that.

imagine if they could run @ the rpm's our little v8's do.

oh and 2 stroke diesels are awesome engines by the way. never seen anything cooler

[rollie]

that motor is crazy, even though its not directly related, its still a 2 stroke diesel, best sounding motor ever!!

i think it produces something ridiculous like 1.5M ft/lb @ a pretty low RPM.

Wonder what the torque is?:eek:

by definition of mechanical horse power

1 HP = 550 ft-lbf/s

so by that 100,000 hp = 55,000,000 ft-lbf/s

desgin equation for horse power from torque is

t=[5252 * horse power]/speed (rpm)

so in that case 100,000 hp @ 100 rpm's = 5,242,000 ft-lbf

I'm gonna go out on a limb and say that's not right. That would be like a 100 hp motor having 5,000 ft/lbs of tq. That isn't even close to making any sense.

Are you sure? Does 50 ft-lbs of torque sound better?

Horsepower is basically torque times speed, speed in this case being measured in RPMs. What YOU are used to is a motor with 50ft-lbs of torque making 100hp, but at what RPM is that at? 6k RPM? Even higher? 8k? 10k?

To make the numbers easy, let's assume it's 10k RPM (that's screaming fast, I know, but let's just go with it). 100hp, 50ft lbs of torque, 10k RPM. In order to achieve that same 100HP at half the speed (half the RPM), you need twice as much torque.

50ft-lbs@10k RPM = 100ft-lbs@5k RPM

Let's take this concept further. We'll start at the very top and work the RPMs down. Each time we will double the torque, and cut the RPMs in half.

50 ft-lbs, 10,000 RPM

100 ft-lbs, 5,000 RPM

200 ft-lbs, 2,500 RPM

400 ft-lbs, 1,250 RPM

800 ft-lbs, 625 RPM

1,600 ft-lbs, 312 RPM

3,200 ft-lbs, 156 RPM

6,400 ft-lbs, 78 RPM.

And NOW, we are in roughly the same RPM range as this monster engine, and you can see, we aren't too far off from your 5,000 ft-lbs of torque that you were saying doesn't make any sense.

It actually makes PERFECT sense.

I guess you're right, never really dealt with anything that low of RPM. Horsepower doesn't really mean anything anyways, since it's just derived from torque, but I didn't calculate anything out. Just saw the numbers and thought it didn't make sense. I stand corrected.

I guess I could have just done some simple math and figure that out before opening my mouth :chinese:

ya i dont know if im truly right in this case, i just know that what i learned in my engineering classes, is that that equation is the basic torque design equation for a mechanical system with a given power rating and a given rotational speed....so i mean i could be off or wrong,

but i was reading somewhere online that large, slow moving boats like that have extremely large props, and that their engines have such low speed that torque is more important than engine power..

The more I think about it, I might be a little off.

Your equation for horsepower to torque, the torque is the standard ft-lbs we're all used to, but the velocity portion is given in feet per second.

Can you convert it to RPMs?

[400exrider707]

The equation from horsepower is just taken from your RPM and your TQ. TQ is something we can measure, horsepower literally means nothing because it's just a number that is taken from TQ.

(Torque x Engine speed) / 5,252 = Horsepower


That's it. If we know the horsepower or the tq, and the RPM, we can figure the other out.

torque x RPM is where the "per second" comes from. You are converting revolutions per minute to radians per second. 1RPM = .10472 radians per second. Take your 550 ft/lbs per second and divide by .10472 and that gets you your 5252, which is where HP and TQ cross on ANY dyno sheet. That is why 5252 is the magic number.

We weren't including the seconds portion in the equation originally, but it's not needed since we can just use the horsepower and the RPM given to figure torque. You were right the first time Wilkin, I think we're just over complicating it now.

I knew most of this stuff already but 100hp and 5,000 ft/lbs still just turns the light on in your head.

[twincat800]

They need to call up Dynatek and have them make a programmer for that engine and bump up them rpms get some hugeee hp numbers!! lol
