  • Crankshaft



    This is the crankshaft for a Wärtsilä-Sulzer RTA96-C engine, the largest reciprocating engine in the world, used in large container ships. It's a 1810-liter engine that generates 108,920 horsepower at 102 RPM, and it idles at 22 RPM... almost 3 seconds per rotation. This crankshaft weighs 300 tons (660,000 pounds) and each piston weighs 12,000 pounds and has a stroke length is 8.2 feet.

    As of 2006 there were more than 300 of these engines in active service.

      Wow, that thing is huge!
      Then look at the flywheel on assembled motor, dang
      How do you start that puppy? Series of smaller engines?

      That’s definitely not one us country boys can tear down in a shed

      What kind of transmission, if any, does that hook up to?
      Or do they have smaller wing engines that aid in maneuverability and that’s a direct drive?
      I don't know ships

          Amazing the scale of engineering that goes into making that engine.

            Amazing!! I'm always fascinated by big machines.

            Fuel burn at WOT?



            Stupidly cliche, I know. But it's gotta be a staggering number.

              Wiki says it is a straight 14 cylinder. When some of the big ships cruise the Savannah River, the motors shake the ground on River Street.

                Seriously?
                That’s some high torque stuff for sure

                    Most modern newer cruise ships us Diesel/Electric, they have 4-6 smaller engines driving generators that supplies electricity to the vessel and the pods.
                    The cargo ships still stay with a single engine and drive system. As evidenced by the RoRo Rollover in Ga.
                    They do burn two different fuels though, one for come and going into ports and one for open ocean.

                          yeah, no. My motto tends to be if it ain’t broke, fix it until it is..
