DTM Brian Posted November 19, 2008 Report Share Posted November 19, 2008 These large engines are designed to power the worlds super oil tankers and large container ships. They are built to the ship owners preferences. They usually request an engine construction of a single unit and single propeller design for ease of maintenance, and not surprisingly any later troubleshooting. A single unit and single screw design has also proved over time to have a longer life span than double or even quad screws. http://titanserver.servepics.com/Titan%20Server/Pictures/Worlds%20largest%20Engine/001.jpg These engines are built in 6, 8, 10, 12 and 14 cylinder configurations. All the engines are straight or 'inline'. The diameter of each cylinder is 3 foot 2 inches with a stroke of 8 foot 2 inches. The 12 cylinder version weighs in at 2000 metric tons and delivers 90,000 Horse Power at 100 Revs per minute, with best fuel economy at 53,244 HP at 90 Rpm. When I mention economy, the 14 cylinder engine for example with a displacement of 25,480 Litres ( 1.56 million cubic inches ) burns up 1,660 gallons of crude ("bunker") oil every hour. ------------------------- The Mathematical calculation : 1,660 gallons/per hour = 39.5 barrels of crude oil/used per hour = $2,844. These figures are worked out from the basis of crude oil @ $72 a barrel*. $2,844 every hour the engine runs or 27.6 Gallons which is $46.00 every minute or 76 cents a second ! That is of course if the ships buy oil at trade price...if not then these figures are the absolute minimum. ( * at time of publishing ) ------------------------- In the image below a worker at the plant is finalising work on the cylinder block. This image shows the piston sleeves. The worker could quite easily have a nap inside one of the bores and no one would notice ! http://titanserver.servepics.com/Titan%20Server/Pictures/Worlds%20largest%20Engine/002.jpg Below are the pistons that will soon be fitted into the engine. Unlike normal car sized pistons these 3 foot diameter pistons incorporate lots of holes and it is through these holes that oil is injected through valves to keep all the working parts at a maximum low wear tolerance. Despite the colossal amounts of power output produced by these engines, surprisingly low wear rates have actually been recorded. Cylinder liner wear for example is only about 0.03 mm down for every 1000 hours of engine use. It must be remembered here that these engines work at about 20 times slower than a normal 2.0 Litre car engine and this is a major contributor to the life of the engine. http://titanserver.servepics.com/Titan%20Server/Pictures/Worlds%20largest%20Engine/003.jpg The image below depicts the 300 ton crankshaft of the 10 cylinder engine. You may notice here that there are steps on the wall of the casing to climb down into the engines sump ! http://titanserver.servepics.com/Titan%20Server/Pictures/Worlds%20largest%20Engine/004.jpg In the image below the pistons shell bearings are being fitted into the engine block. They are lowered into place by a crane and guided in by two workers and a supervisor.. They keep all surfaces of the engine clean at this stage as any grit or dirt could later add wear to the engine or worse destroy it, so the workers are wearing special cloth overshoes so as not to leave any abrasions on the fine working surfaces. Also you may notice that sheeting is covering the rest of the engines crankcase bearing housing to keep the dust off. These engines cost many millions upon millions of dollars; in fact, more than the ship itself that they are installed into. http://titanserver.servepics.com/Titan%20Server/Pictures/Worlds%20largest%20Engine/005.jpg 100,000 HP was actually achieved on a test bed in the workshop with the 14 cylinder model, running the engine flat out at just under 102 RPM. 102 Rpm may sound slow compared to a normal sized car engine that operates at about 2-4000 rpm, but when an engine is as big as this then fast engine revolutions are made obsolete by the sheer power output. 1 Quote Link to comment Share on other sites More sharing options...

Farkas Posted November 19, 2008 Report Share Posted November 19, 2008 I'd be curious to know how they ignite that much fuel and get a clean burn.. that's amazing. Quote Link to comment Share on other sites More sharing options...

starkmaster03 Posted November 19, 2008 Report Share Posted November 19, 2008 That is awsome. I can't imagine how long it takes to assemble one and how many people. Quote Link to comment Share on other sites More sharing options...

Main3s Posted November 19, 2008 Report Share Posted November 19, 2008 So...I'm thinking...FD swap? Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted November 19, 2008 Author Report Share Posted November 19, 2008 So...I'm thinking...FD swap? There is a small increase in torque to be found in this engine over the FD (Torque x Engine speed) / 5,252 = Horsepower 100,000 HP at 102 Rpms= 5,149,019 Foot Pounds of Torque. Of course this is before we add a turbo or nitrous. Quote Link to comment Share on other sites More sharing options...

thorne Posted November 19, 2008 Report Share Posted November 19, 2008 It would take like 20 15lb bottle just to get 1 shot off. Or more . I'd 40 roll it. Quote Link to comment Share on other sites More sharing options...
Oo0martelle0oO Posted November 19, 2008 Report Share Posted November 19, 2008 They should knife edge the crank. Quote Link to comment Share on other sites More sharing options...
351mach11647545510 Posted November 20, 2008 Report Share Posted November 20, 2008 goes to prove there's no replacement for displacement. on a side note... I wonder if that offer that with vtak Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted November 20, 2008 Report Share Posted November 20, 2008 So under full load, the 14 cyl model is shoting a fuel charge of just a hair over 5oz of diesel per ignition event. That is alot of heat to disipate once every 1.2 seconds. Quote Link to comment Share on other sites More sharing options...
Guest 614Streets Posted November 20, 2008 Report Share Posted November 20, 2008 They should knife edge the crank. Lol at knife edging it when it runs at 102 rpm Scraper maybe? Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted November 20, 2008 Report Share Posted November 20, 2008 I didn't even think they used diesel motors in ships anymore. most of them use a reactor to make steam and run a turbine. Quote Link to comment Share on other sites More sharing options...
Skinner Posted November 20, 2008 Report Share Posted November 20, 2008 I didn't even think they used diesel motors in ships anymore. most of them use a reactor to make steam and run a turbine. doesn't run on diesel, runs on crude oil.
