I work for this company as a service engineer. I have worked on these engines aboard some ships and when you are aboard it is hard to tell how big the engine is because you can never see the whole thing. I can tell you when you work on it you just open the door and walk right in.
 
Okay, I'm bad for continuing this thread, but...



How is one of these things started and what are the operating parameters? Huge equipment like this fascinates me and I would love to know more about it.
 
Gary_K7GLD... . I think on the big ones like that they use the P7100. :-laf Gary... I just realized a few days ago that you are a ham... I have been one for 3yrs and love it!!!!
 
This particular engine is a 2-stroke and redlines at 100 rpm. Probably not the best canidate for an engine swap. If you are interested check www.wartsila.com this is the web site for the company I work for. They build engines from 200mm bore at 3Cyl. to the one pictured Which is an 14RTA96. They even have this particular engine without a camshaft. Which means the fuel delivery and openining of the exhaust valve are controlled by computer. Amount of injection, timing, all of this can be controlled at all times which results in no visible smoke from the stack at any time.

What will they think of next.

most engines this size are air started by forcing air into a cylinder that is just past TDC. and the engine is stalled, and started in reverse when the ship wants to go in reverse. there is a hydraucally adjustable cam follower that changes the injection timing from forward rotation to reverse rotation. many have electric blowers on them to drive the engine scavanging air until the turbos spool up... if i can find the link on my old pc, there is a webpage that is several pages long that talk about the internal works of similar engines [construction, internals, externals, injection...
 
My dad worked for the natural gas pipeline several years ago, like when I was born. Anyways, their pumper engines were pretty huge. He said when they went to start it, first they'd turn on the oil pumps and let them run for a little bit. Then using compressed air, they'd get the turbos spinning. Once they were up to speed, they'd use air to force pistons down till the engine fired. He said three people could stand comfortably in each cylinder. The radiators were horizontal and were around 200 feet long.
