Shipping goods from China to the U.S. is big business. And when we say big, we're talking 1,300-foot-long ships that weigh 170,974 tons. The cargo ships in question can carry 11,000 20-foot shipping containers at a breakneck speed of 31 knots.

That's a lot more oomph than the typical 20-knot cruiser, and the reason for the extra push is the world's largest diesel engine. The 109,000-horsepower Wärtsilä-Sulzer RTA96-C, which first set sail in the Emma Mærsk in 2006, weighs in at a rotund 2,300 tons, and it's 44-feet tall and 90-feet long. In other words, the TRA96 is the height of a four-story building, and longer than a Christmas Eve line at Sam's Club. Within that massive exterior rests 14 cylinders that each consume 6.5-ounces of diesel fuel every cycle. And, if you like torque, there's enough twist to rip an M1 tank to shreds, though the massive mill churns at only 102 rpm.

That's a lot of motor to ponder, and we'd be imagining the size of that camshaft, if it had one. This turbocharged two-stroke features common rail tech that utilizes a high-pressure fuel rail to supply fuel to individual solenoid valves. That means improved fuel economy and better performance, which is nothing short of essential in such a massive ship.

So far there are 25 such engines patrolling the world's oceans, and another 86 are on the way. And since these mills can get a shipment from China to LA in four fewer days than their competitors, we wouldn't be surprised to see still more engines on the way.

      Engine swap for my MS3 comin' up. Torque rules, visibility is overrated anyway....

        109000 horsepower at 102 rpm means... wait for it... 5,612,431 foot pounds of torque. FIVE POINT SIX FRIGGIN MILLION LB-FT!!! I really hope you enjoy torque steer. Because it is on the menu.

        They did. It's just that you can't see it under the engine. ;)

      Can't wait for someone to put this in a 97 civic.

        It doesn't have VTEC, it automatically sucks.

      Sweet! Swap this puppy into an old CRX and you got a kick ass power-to-weight ratio! V-Tech, yo!

      72.5 gallons of diesel every minute. That's awesome!

      Good god, look at the turbo on the one in the cover photo. The round thing peeking out in the upper right corner. It's the size of a new beetle! What's the displacement on the 14 cylinder?
