It's a turbocharged direct injection diesel, that's a lot different from a normally aspirated carburetor two stroke that uses the crankcase and has fuel mixture blow through. Two stoke diesels are more efficient than four stroke diesels, 50% vs 35%. At least when in a low speed long stroke configuration like marine engines.
This engine just fascinates me with every characteristic being almost unbelievable including I’m sure its cost. According to most, this 2-stroke is super efficient for any diesel, about 50% which is amazing compared to 20%-30% efficiency that is far more typical. That said, however, this beast still can consume 3600 gallons of bunkers (heavy fuel oil with the consistency of tar) per hour. Again, PER HOUR. For that consumption you get 102rpm and almost 109,000 horsepower or about 80MW. That’s megawatts, with an “M.” The impressive Model3P generates a bit over 400 ft-lb of torque, not even a rounding error for the Wärtsilä’s over 5,600,000 ft-lb, needed to turn a 490ft/150m prop shaft that ends with a single, six-bladed huge (31.5ft/9.6m) and heavy (131 tons) prop on the Maersk container ship Emma to propel that beast up to 27knots (or more depending upon the information source), an incredible speed for a fully-loaded commercial vessel of its size.
