taken from webpage: link 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 it's most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour. 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:  - 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:  - 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!:  - The first completed 12 cylinder engine:  - sorry actually this page was already post in the off topic section of this forum [ November 20, 2003, 04:48 PM: Message edited by: CLguy ]

Hasn't this issue been hashed out enough, if you did a 10 second search you would have found the answer!!! [Big Grin] [Big Grin] [Big Grin] I would guess that this engine would probably take the entire stock of available German Castrol. Given it is 89 feet long, I would guess the oil capacity to be several thousand gallons. I bet they do oil analysis on this one before they change the oil. Cary

BTW Shouldn't this topic be moved to the "Light Duty Submarine, Aircraft Carrier and Shuttle Mover Engine Oil" Forum? [I dont know]

CLguy, Don't you think you should beef up the suspension a bit before installing this engine? [Eek!] And check those clearances on the journals and bearing shells before you drop that puppy in. [Big Grin] I'd use a 70 weight Monograde with 300 gallons of Schaeffer's #132 and 100 gallons of LC. Odis Beaver would love this! [Cool] OK, just did a calculation on bearing clearances - Should be 0.0095 " or 9.5 - thousandsth of an inch or 0.24 mm!. [ November 20, 2003, 05:54 PM: Message edited by: MolaKule ]

Molakule, What are you thinking!!! Everyone knows that an engine this size with such close clearances needs to have Honda 5W20 or it will simply self destruct. This of course is for the crank sump. The oil for the cylinder liner injction should be 5W50 Castrol Syntec! I mean only the best right!!! My Super tanker mechanic has said that M1 will cause hull breachs!! I asked about Redline and he said that Redline was not compatable with engines that are made out of metal! Oh well I better get started I have alot of 1 quart bottles of 5W50 syntec to pour in! [LOL!]

Hi, the general opinion in OZ is that such engines are started on the Castrol SLX 0w-30 that has been withdrawn from sale here The reason appears to be something to do with "what will we do with all this Castrol "super" oil that we can't sell" and this was BP's answer The first UOA will be interesting! In the meantime just take an Alka-Sulzer to ease the pain Regards

Could you imagine an Amsoil dealer getting that account? Do you think that has a regular dipstick to check the oil? That would be pretty funny: "Hey Mac, we're a drum low!"

WTF is that giant fine toothed gear in the middle of the crankshaft? I foresee oil shearing problems on the horizon... [Cool] [ November 22, 2003, 11:46 PM: Message edited by: jsharp ]

I am sure that those teth are not as fine as they seem. Lets just hope that the enginers gave it more then a 4 quart sump and did not recomend long drains with cheap 5W30!

With those clearances and Ford 0W20, who needs a filter??? Crank throw looks to be 10-12 feet total. Better get a new battery for winter starting! [Big Grin] [ November 24, 2003, 02:09 PM: Message edited by: MolaKule ]

He listed 38" bore and 98" stroke so this thing is massively undersquare. I'm sure its a real "torquer" [LOL!] I'm still wanting to know the oil pump flow rate. Listing it in drums per second would probably be the easiest...

You're on the right track - but, it's nearly three stories long... What would likely be the operating speed under load - 200 RPM? You suppose a Sears DieHard can start this thing? (I know, I know, it's probably turned over by direct injection of compressed air.)
