The Most Powerful Diesel Engine Ever Built Runs at 102 RPM

Dive into the world of extreme engineering! This is the Wärtsilä-Sulzer RTA96-C (RT-flex96C) — the largest and most powerful internal combustion engine ever created by humanity. This 14-cylinder, two-stroke turbocharged diesel giant weighs over 2,300 tons, stands as tall as a four-story building (13.5 meters), and stretches nearly 27 meters in length. Its most mind-blowing feature is its ultra-low operating speed of just 102 RPM (revolutions per minute). At this pace, it generates a staggering 7.6 million Nm of torque and a colossal 108,920 horsepower. This behemoth is designed to single-handedly push the world’s largest container ships (like the Emma Mærsk) across the oceans at speeds exceeding 25 knots. Learn how this engineering marvel works, how much fuel it consumes, and why its crankshaft alone weighs as much as a commercial airliner!
