For when the grass gets really long...
All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
What kind of grass are we talking about?
What is that?
No really.
What the hell is that?
I'd assume it's an engine for a ship.Originally Posted by KG4CGC
Yep, it's a ship engine. Here's the blurb:
One hundred and eight thousand horsepower, Five and a half million ft/lbs of torque...The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan's Diesel United, Ltd built the first engines and is where some of these pictures were taken. It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them. The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.
Some more facts on the 14 cylinder version:
Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons).
Length: 89 feet
Height: 44 feet
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 ft/lb at 102rpm
Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion. For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range. Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.

The world's largest Diesel engine powers the world's largest container ship, the Emma Maersk.

There was a little problem however:

Bigass straight six? :shock:
That truck is pretty slick too.

of knowledge to the nipples of ignorance?" ~ Professor "Dick" Soloman
For visualization: A cylinder a meter wide and about 2.32 meters tall would have that volume. Impressive.
Worked for Wartsila in Zwolle, now closed, where they buildt these big ass engines, doing maintenance work on their stainless steel tanks and piping, saw these engines being buildt and tested.
Now there were some nice engines..... bit heavy on the use of oil, but then, who cares ;)

But wait, there's more!
