The World's most Poweful Piston Engine
 

The Wartsila NSD (Sulzer) RTA96-C two-stroke diesel engine is the most powerful and most efficient piston prime-mover in the world today. Bore just under
3'-2" and the Stroke is just over 8'-2". For those counting, that comes out to 1,333,722 cubic inches (read as: one million three hundred thousand plus!) for the twelve cylinder version!

Available in 6 through 12 cylinder versions (all inline). Engine weight exceeds 2,000 tons in the 12 cylinder version (the crankshaft alone exceeds 300 tons).

Point of maximum continuous power is 89,640 HP at 100rpm with the 12 cylinder version. Point of maximum fuel economy is 53,244 HP at 90 RPM. The 12-cylinder engine exceeded 100,000 horsepower during overspeed testing (all of 101.5rpm!) while under test at Japan's Diesel Union works (who built the first engines and from who these pictures are taken).

Fuel consumption at maximum power is 0.278 lbs/HP/hour (BSFC). Fuel consumption at maximum economy is 0.260 lbs per HP per hour.

At maximum economy the Sulzer engine exceeds 50% thermal efficiency i.e. more than 50% of the fuel going into the engine is converted to power) For comparison, consider that automotive and small aircraft spark-ignition engines have British Standard Fuel Consumption figures in the 0.40-0.60 lbs/HP/hour range and 25-30% thermal efficiency.

Even at its most efficient power setting, the Sulzer 12 cylinder consumes nearly 1,660 gallons of heavy fuel oil an hour.

what the hell is it for?

That's Korean writing.

I think it's probably used in big boats.

rotaries are better

dude turbo that bish!

:repost:

:werd: I'm also wondering why an engine that is "tested" in Japan has two huge banners in korean? :confused:
