Go big or go home

Those are some neat pics. I'm pretty sure the engine in the first picture is a smaller version, and not the biggest 14 cylinder available. My dad worked in shipping his whole life, so I spent a good deal of my childhood running around in the engine rooms of ships. At that time he worked for Carnival Cruise lines, and the cruise ships don't have engines quite that big, but pretty close. The Sulzer 14 cylinder engines are most recent ones. Sulzer had to dramatically increase the strength of the crankshaft to go from a 12 cylinder to a 14 cylinder engine.

I remember when I was a kid, the ship had some sort of problem on the crankshaft. My dad crawled into the crankcase of the engine and had the crew turn the engine over so he could crawl down where he needed to go. He's crazy. If for any reason they couldn't crank the engine again, he would have been stuck there.

Awesome story man
 
Well here's some interesting facts. They idle at about 80rpms, and full power is usually around 180rpms. Everything is built for ease of maintenance. The cams cam be removed from the camshaft and replaced individually. You also never have to change the oil. Provided no water gets in the oil, you just keep filtering it for the life of the engine. The fuel is so crude, that at room temperature, it's a solid. You have to heat it to over 200 degrees Fahrenheit just to pump it. On a typical ship engine, the compression ratio is about 30:1, and the turbochargers run at 65 psi at average cruise power. If one turbocharger fails, the engine power is reduced by about 65%. The engines don't use electric starter motors, the are started by blowing compressed air into the cylinder. They are designed to extract as much energy from the fuel as possible. The heat from the exhaust is used to desalinate sea water for drinking water on the ship.
