        I've seen the eight cylinder version that is owned by the city of Sebring, FL. It is used as a peaker power plant. They have two of these engines. They use bunker oil for fuel. In order to pump the fuel from the storage tanks to the fuel injection system it must be heated to 120 F in order to flow. Each fuel injector injects approximately 20 ounces of fuel into the cylinder at each stroke. The cylinder measures 36" across with a 5 foot stroke. The entire engine measures 66 feet long and 44 feet high. This engine runs at 120 RPM.

        I was able to see into one of the inspection ports on the side of the engine block. It was about the size of a large manhole cover. You knew the engine is large when there are ladder rungs going up each web between the cylinder. Going into the bottom of each piston were two telescopic tube that carried cooling fluid into the crown of the pistons.

        Through a friend who works there I was able obtain a piston ring from this engine. Its the size of a hula-hoop! Its about 3/4" thick by 13/8 wide.

              Thanks a lot! Now I've got the Oohmpa Lohmpa song in my head. Just try not to think of _It's a Small World After All_ OK. I hate it when that happens.

                  Germans call that an ear-worm. The last pattern shop I worked at, we "played that game with each other all day long, x-mas was nasty..."Frosty the snow man, was a happy jolly soul..." Best remidy I've found is to think of every obnoxious song I can think of as fast as I can, don't give any of them a chance to grab hold.

                  Good luck

                    at 1660 gallons of fuel per hour it could be cheap to run

                    I want to see the lathe that they use to turn that crank

                      There is a floating power plant in Jamaica at Old Harbor that has 6 of the 8 cylinder wartsila diesel power generators. It is called the Doctor Bird. The Doctor Bird is a humming bird and is the national bird. These are hugh engines with multipal levels. The machine shop is something else. Everything is there to repair and rebuild the engines. We were looking at buying one of the diesel generators for additional power at the alumina plant where I worked.

                        Matt,

                        Yes, how do they make the cranks?

                        Some time ago I asked Sulzer this question, and they replied saying that single piece forgings are used for engines up to 'quite large sizes' in fact up to the largest of the four stroke engines (640mm bore).

                        However the two stroke engines have long had built-up crankshafts. The crankshaft is built from forging for each cylinder (one crank pin and two crank webs) and the main journal. The journals are shrink fitted into the webs. In all cases, however, the longer crankshafts are seperated into perhaps two sections for ease of handling and transport.

                          Matt,
                          For some reason I'm on Wartsila's distribution list for their quarterly magazine, from memory the 10 cyl crankshaft fully assembled weighsover 330 metric tonnes, built up as you say, Awseome to say the least. All their large engines are built and assembled by the licensed shipyards in Korea and Japan, Spain etc.

                            One would think that at some point the weight and the inertia of the internal parts would make a piston driven engine impractical - or at least impossible to machine. Guess they haven’t gotten to that point yet!

                              Now that would make a great go-kart engine.
