The crankshaft of the world’s largest diesel engine
The crankshaft of the Sulzer RTA 96, the world's largest diesel engine, is a marvel of engineering. This colossal component, stretching over 14 meters in length, is forged from high-strength steel to withstand immense pressures and forces. Weighing approximately 300 tons, it comprises seven to fourteen crank throws, depending on the engine's configuration, each meticulously machined to precise
tolerances.
Designed to convert the linear motion of the pistons into rotational energy, the crankshaft operates with unparalleled efficiency. It rotates at a leisurely 102 RPM, translating the colossal power generated by the engine’s 14 cylinders into a smooth, continuous propulsion force. Each throw of the crankshaft is paired with a massive connecting rod and an equally impressive piston,
highlighting the sheer scale of this mechanical behemoth.
The crankshaft's robust construction and impeccable balance are crucial for the reliable operation of the Sulzer RTA 96, ensuring it can deliver its staggering output of up to 107,390 horsepower. This engineering masterpiece exemplifies the pinnacle of marine diesel engine technology, driving some of the largest container ships across
the oceans with unparalleled power and efficiency.
