Huuuuge Diesel Engines
I hadn’t really thought about it, but the giant ships that transport all our goods across the ocean run on diesel engines. Now this isn’t your standard 5 or 6 liter engine found in a Dodge or a Ford. And it’s not the same 12-15L engine you’d see under the hood of a big rig rolling down the street.
No no, these things are MASSIVE. Check out this picture of a Wartsila diesel engine:
That’s the crankshaft. The crank journal is bigger around than the guy standing next to it! If you look closely it looks like there are ladders built in to climb down under the crank too.
I’m not sure what a mechanic has to do to be qualified to work on that, but sign me up!
