6L6EY22W

This is a marine propulsion engine designed for commercial ship applications. Manufactured by Yanmar, the 6L6EY22W boasts a powerful 1560 kW output at 750 rpm. Fueling this engine is heavy fuel oil (HFO) or marine diesel oil (MDO). The engine features a 6-cylinder inline configuration with a 220 mm bore and a 320 mm stroke. The engine's specifications include an estimated dry weight of 10,000 kg and an emissions standard compliant with IMO Tier II. Common failures in this engine family can include turbocharger wear and malfunctions due to contaminated oil or carbon buildup, indicated by smoke emissions under load. Cylinder head gasket leaks, both internal and external, can result from scratches on sealing surfaces, inadequate cleaning, or improper tightening torque. Wear on fuel injectors due to cavitation, causing a trumpet-shaped enlargement of the injection nozzle bore, can affect pressure buildup and fuel atomization. Regular monitoring of bearing wear and oil analysis for metallic particles are crucial for detecting potential issues with bearings and connecting rods.
