Worlds largest piston engine - 100,000hp @102rpm

[Oldfisti]

I received this in an e-mail today.

    The world's biggest engine is the Wartsila-Sulzer RTA96-C. It is a turbocharged two stroke diesel engine and it is the most  powerful and efficient low revolution engine in the world today.

    The Wartsila-Sulser is manufactured by the Aioi Works in Japan and is part of Japans Diesel United Ltd engine manufacturers. Below is an 89 foot long 44 foot wide 12-cylinder DIESEL engine.  These large engines are designed to power the world's super oil tankers and large container ships.

    Engines are built in 6, 8, 10, 12 and 14 cylinder configurations. All the engines are 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 Horsepower at 100 Revolutions per minute (rpm's), with best fuel economy at 53,244 HP at 90rpm.

    100,000 HP was actually achieved on a test bed in the workshop with the 14 cylinder model, running the engine flat out at just under 102 RPM.

Think I can get one in the S4R?

It'll surely outdo that 24 cyl bike!    I didn't notice any torque figures. Would almost think it's unmeasurable...       

[Oldfisti]

UPDATE:   2008 specs say it now has 114,800hp!!     

5,608,312 lb/ft at 102rpm torque!

By my calculation, that would be about 5.2 million ft/lbs.   

And that's at peak horsepower.  So who knows what the peak torque might be.

Good Guess...

He beat me to it, I guess.  But that was an updated horsepower number.

Horsepower, RPM, and torque can always be determined as long as you know two of the three and remember 5252:

HP = (Torque x RPM)/5252   

[NAKID]

So:

tq= (hp x 5252)/rpm

[Popeye the Sailor]

So:

5252 = (Torque x RPM)/HP 

[NAKID]

So:

rpm= (hp x 5252)/tq

[ducpainter]

geeks...

[Jobu]

So:

5252 = (Torque x RPM)/HP 

Yes.  Torque and Horsepower are always the same at 5252 RPM's.

[Popeye the Sailor]

Yes.  Torque and Horsepower are always the same at 5252 RPM's.

I's an engineer.

I's an engineer.

I've met plenty of "engineers" that would have trouble with that one.  Of course, they don't own Ducati's either.
