The Most Powerful Diesel Engine in the World!

The Most Powerful Diesel Engine in the World!

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. 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 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:




Some pistons

And some piston rods:



The "spikes" on the piston rods are hollow tubes that go into the holes you can see on the bottom of the pistons (left picture) and inject oil into the inside of the piston which keeps the top of the piston from overheating. Some high-performance auto engines have a similar feature where an oil squirter nozzle squirts oil onto the bottom of the piston. The cylinder deck (10 cylinder version). Cylinder liners are die-cast ductile cast iron. Look at the size of those head studs!

Amazing Photo Shot

Disturbing and unusual pictures
Some of these are facinating, some are disturbing, all tell a story.

Got some interesting pics from Honda tech, on this theme, add some more!

There are new photo's from another (or the same) ship in a storm here


Some scared animals there ... yet a beautiful pic

Thanks to Biogeek on Redit for the origin of this picture.

This awsome picture was taken in the Bitterroot National Forest in Montana on August 6, 2000 by a fire behavior analyst from Fairbanks, Alaska by the name of John McColgan with a Digital camera.

On 6 August 2000, as several fires converged in the Sula in western Montana, John McColgan, a fire behavior analyst in the employ of the USDA Forest Service snapped the spectacular photograph shown above with a digital camera. As McColgan described the experience to a writer for the Western Montana newspaper

... Quote: That's a once-in-a-lifetime look there. I just happened to be in the right place at the right time. I've been doing this for 20 years and it ranks in the top three days of fire behavior I've seen.

"They know where to go, where their safe zones are," McColgan said. "A lot of wildlife did get driven down there to the river. There were some bighorn sheep there. A small deer was standing right underneath me, under the bridge."

McColgan snapped the photo with a Kodak DC280 digital camera. Since he was working as a Forest Service firefighter, the shot is public property and cannot be sold or used for commercial purposesFrom snopes.com

A man-made sun rose over Bikini Atoll on March 1, 1954. Seen here from 50 miles away, the 15-megaton hydrogen blast called Bravo ranks as the largest U.S. test, a thousand times greater than the atom bomb dropped on Hiroshima in 1945


Anyone for shark soup?


Sub at the beach

A russian sub cruises the beach somewhere in Russia.



OK what is this then?

The text says "It's nuclear warheads re-entering the atmosphere, luckily only testing this time." here and the pic name says they are peacekeepers. But if it really shows missiles entering the atmosphere, then its a stunner of a pic.

Thanks to Lyon on Redit for finding the information about this picture.

LGM-118A Peacekeeper missile system being tested at the Kwajalein Atoll in the Marshall Islands.

The lines shown are the re-entry vehicles -- one Peacekeeper can hold up to 10 nuclear warheads, each independently targeted. Were the warheads armed with a nuclear payload, each would carry with it the explosive power of twenty-five Hiroshima-sized weapons.



The pic is real!


That pics shows a MIRV re-entry.

Multiple Independently targetable Re-entry Vehicle, or MIRV is a collection of nuclear weapons carried on a single intercontinental ballistic missile (ICBM) or a submarine launched ballistic missile (SLBM). Using a MIRV warhead, a single launched missile can strike several targets, or fewer targets redundantly. By contrast a unitary warhead is a single warhead on a single missile.MIRV Wikipedia article

The US Minuteman 3 is the only US land-based MIRV ICBM currently in use. These MIRV capable ICBM's are especially used because they are harder to counter with anti ballistic missile systems due to number of independent re-entry vehicles in the re-entry phase. True to keeping the world more on edge, the Russians are developing the Bulava(SS-27 class) sea-launched MIRV ICBM. Supposedly the most advanced MIRV ICBM to date and still under development. This is obviously in response to the US Ballistic missile "Shield" that is under development.

Okay enought of this rant, Here is night pic of MIRV re-entry:



National Geographic discover giant skeleton

Nope its a hoax, but a goodie that has been around for a while.

Since 2004 this doctored image has helped give legs to tall tales of ancient giant humans. (Read full story.)

At least one version of the story—published in the March 2007 issue of India's Hindu Voice monthly and cited in countless blog entries and emails this year—claims that a National Geographic Society team helped make the "discovery" in India. (The National Geographic Society owns National Geographic News.)

The picture, however, is an innocent fake.

The image was lifted from Worth1000, a Web site that hosts contests for digital artists. Created by an artist using the alias IronKite, the picture placed third in a 2002 competition titled "Archaeological Anomalies 2," which asked contestants to “create a hoax archaeological discovery.”
