    World's biggest engine










    The Wartsila-Sulzer RTA96-C



    Maximum power: 108,920 hp at 102 rpm


    Maximum torque: 5,608,312 lb/ft at 102rpm






    The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aloe 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.













    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.


    A cross section of the RTA96C:






    The internals of this engine are a bit different than most automotive engines.


    The top of the connecting rod is not attached directly to the piston. The top of the connecting rod attaches to a "crosshead" which rides in guide channels. A long piston rod then connects the crosshead to the piston.


    I assume this is done so the sideways forces produced by the connecting rod are absorbed by the crosshead and not by the piston. Those sideways forces are what makes the cylinders in an auto engine get oval-shaped over time.


    Installing the "thin-shell" bearings. Crank & rod journals are 38" in diameter and 16" wide:






    The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version. Note the steps by each crank throw that lead down into the crankcase:






    A piston & piston rod assembly. The piston is at the top. The large square plate at the bottom is where the whole assembly attaches to the crosshead:

    على المرء ان يسعى الى الخير جاهدا وليس عليه ان تتم المقاصد




    تحلو مرارة عيش فى رضاك ولا اطيق سخطا على عيش من الرغد


    سوف يكون تواجدي محدودا في الفترة القادمة وذلك لظروف خاصة.. اسأل المولى التوفيق لى و للجميع.
