The Largest And Most Powerful Diesel Engine in The World
By Kaushik Thursday, March 21, 2013 Engineering 13 comments

Container ships are some of the largest and heaviest vessels that plough on the seas. They measure up to 1,200 feet in length and can move 10,000 to 16,000, 20-foot steel containers in one trip. To push these vessels through the water require immense amount of energy, that are derived from massive diesel engines. Some of the larger cargo ships have engines that look like this.

RT-flex96C-1

This is RT-flex96C - a two-stroke turbocharged diesel engine designed by the Finnish manufacturer Wärtsilä and is currently the largest and most powerful diesel engine in the world. Standing at 13.5 meters high and 26.59 meters long, it is almost as big as a small apartment. It weighs over 2,300 tonnes and its largest 14-cylinder version produces 80,080 kW of power.

The 14-cylinder version was put into service in September 2006 aboard the Emma Mærsk, a container ship – the largest at that time. The design is based on the older RTA96C engine, but revolutionary common rail technology has done away with the traditional camshaft, chain gear, fuel pumps and hydraulic actuators. The result is better performance at low revolutions per minute (rpm), lower fuel consumption, and lower harmful emissions.

One of the most remarkable feature of this behemoth is the high thermal efficiency, which exceeds 50%. This means that 50% of the heat generated by burning fuel is converted to power. For comparison, most automotive and small aircraft engines can only achieve 25-30% thermal efficiency. Even at its most efficient power setting, the big 14-cylinder engine consumes 1,660 gallons of heavy fuel oil per hour.

Some stats about the engine:

Bore: 960 mm
Stroke: 2,500 mm
Displacement: 1,820 liters per cylinder
Mean piston speed: 8.5 meters per second
Engine speed: 22–102 RPM
Torque: 7,603,850 newton metres (5,608,310 lbf·ft) @ 102 rpm
Power: up to 5,720 kW per cylinder, 34,320–80,080 kW (46,680–108,920 BHP) total
Mass of fuel injected per cylinder per cycle: ~160 g (about 6.5 ounces) @ full load
Crankshaft weight: 300 tons

But You know how to stop world hunger and wars over the globe Blacka ?

Why should we? Hunger and war drive effort.

I don't know about wars, but a ship this big can carry a whole lotta groceries.

Technology Submission - Novel Rotary-Turbo-InFlow Tech - Featured Development

GEARTURBINE PROJECT
Atypical InFlow Thermodynamic
Technology Proposal Submission
Novel Fueled Motor Engine Type

*State of the art Innovative concept Top system Higher efficient percent.
Have similar system of the Aeolipile Heron Steam device from Alexandria 10-70 AD. -New Form-Function Motor-Engine Device. Next Step, Epic Design Change, Broken-Seal Revelation. -Desirable Power-Plant Innovation.

YouTube; * Atypical New • GEARTURBINE / Retrodynamic = DextroRPM VS LevoInFlow + Ying Yang Thrust Way Type - Non Waste Looses

-This innovative concept consists of hull and core where are held all 8 bteps of the work-flow which make the concept functional. The core has several gears and turbines which are responsible for these 8 steps (5 of them are dedicated to the turbo stages). The first step is fuel compression, followed by 2 cold turbo levels. The fourth step is where the fuel starts burning – combustion stage, which creates thrust for the next, 5th step – thrust step, which provides power to the planetary gears and turbines and moves the system. This step is followed by two hot turbo steps and the circle is enclosed by the final 8th step – bigger turbine. All this motion in a retrodynamic circumstance effect, wich is plus higher RPM speed of self reaction motion, because is like when something go to a something is coming. Its a Rotary-Turbo-InFlow Technique principle.

*8-X/Y Thermodynamic CYCLE - Way Steps:
1)1-Compression / bigger
2)2-Turbo 1 cold
3)2-Turbo 2 cold
4)2-Combustion - circular motion flames / opposites
5)2-Thrust - single turbo & planetary gears / ying yang
6)2-Turbo 2 hot
7)2-Turbo 1 hot
8)1-Turbine / bigger

-With Retrodynamic Dextrogiro vs Levogiro Phenomenon Effect. / Rotor-RPM VS InFlow / front to front; "Collision-Interaction Type" - inflow vs blades-gear-move. Technical unique dynamic innovative motion mode. [Retrodynamic Reaction = When the inflow have more velocity the rotor have more RPM Acceleration, with high (XY Position) Momentum] Which the internal flow (and rotor) duplicate its speed, when activated being in a rotor (and inflow) with [inverse] opposite Turns. A very strong Novel concept of torque power thrust.

-Non-waste parasitic looses system for cooling, lubrication & combustion.

-Shape-Mass + Rotary-Motion = Inertia-Dynamic / Form-Function Wide [Flat] Cylindrical shape + positive dynamic rotary mass = continue Inertia kinetic positive tendency motion. Like a Flywheel.
