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 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 lb/ft 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.

    Reading this actually depressed me. Aparently there is NO alternative to oil… @jimmieq: Next is Oil spills, Destruction of the eco-system,..Hopefully some form of mass-genocide.

    @Moe: No, nest is Megas XLR and that robot Godzilla.

    Also, how much will this set me back?

    in the future it won’t matter if there are alternatives. when it runs out, our demand for oil will be irrelevant. segways and bullet trains, segways and bullet trains

    What happened to the “no more wall of text” thing?

    Some thermodynamics geek back me up here, but isn’t >50% thermal efficiency impossible?

    I take it you have never heard of nuclear power at all have you ?

    @ Moe: Did you miss that oil is 100% all natural and occurs in nature? Did you also miss that it leaks from the ground into the ocean all the time, regardless without the help of man? That the eco-system is constantly changing, without regard for man? That we have hardly a basic understanding of it. “You think man can destroy the planet? What intoxicating vanity. Let me tell you about our planet. Earth is four-and-a-half-billion-years-old. There’s been life on it for nearly that long, 3.8 billion years. Bacteria first; later the first multicellular life, then the first complex creatures… Read more »

    We can pollute it to toxic death for most species on the planet, and that’s what people mean when they say “destroy” it.

    @Dyna-Mole: While I agree that Chrichton and GAThrawn are smoking delusion, the free market system will work this out on its’ own. Eventually extracting oil will become so expensive (because the oil will get harder and harder to get), that alternatives will become economically preferable. Solar powered hydrogen production, etc. is a pipe-dream now, only because oil is still artificially cheap.

    @WistfulD: No expert expects oil to last into the 22nd century. Eventually a switch will be made.

    @GrandAdmiralThrawn: I only read the first line or so.. Yes oil is natural, but why do we need to burn it? Technology is also so readily avalible… so how but some technology? FYI- they just came out with a HYBRID denali/yukon- it now gets %50 better gas milage!!!! OMG 24-28 MPG!!! WOW THATS AMAZING! GO HUMANS! Go fuck yourself. AND MIKEYS DEAD!
