The flywheel marked K 32001 is a vital rotating mass directly mounted on the crankshaft of the Sulzer ZV40/48 engine. Designed to store rotational energy, it ensures smooth and stable engine operation by evening out power pulses and reducing torsional vibration. This component also plays a key role in starting procedures and timing control, serving as a reference for engine diagnostics. Its robust construction allows it to endure the massive torque and rotational stress typical in large marine and stationary diesel engines.
