Marine engineers and operators rely on reliable auxiliary engines to ensure the smooth operation and safety of their vessels at sea. HiMSEN’s 8LH21/32P is a robust and versatile diesel engine designed for marine applications, featuring an 8-cylinder layout with a bore of 210 mm and a stroke of 320 mm. This engine delivers a continuous power output of 1760 kW at 900 rpm, running on Heavy Fuel Oil (HFO) or Marine Diesel Oil (MDO). The engine is equipped with a compression ratio of 17:1 and a maximum injection pressure of 2000 bar, ensuring efficient combustion and performance. It is Tier II and Tier III compliant with Selective Catalytic Reduction (SCR) technology. However, like any complex mechanical system, it can face common issues such as piston cooling nozzle blockages, crankcase oil mist build-up, exhaust valve seat erosion, and fuel injection nozzle coking, which require vigilant maintenance and inspection.
