Auxiliary Engine (Generator Set) · Auxiliary Engines
This marine engine employs a 4-stroke, turbocharged, Miller Cycle design optimized for heavy fuel operation, ensuring efficient combustion and performance. The HiMSEN 8LH32/40-GS-60Hz, part of the H32/40-GS family, delivers a continuous power output of 3520 kW at 900 rpm, suitable for demanding maritime applications. It supports both Heavy Fuel Oil (HFO) and Marine Diesel Oil (MDO) up to 700 cSt at 50°C, providing flexibility in fuel supply. The engine features a bore and stroke of 320 mm and 400 mm respectively, and has a displacement of 193–643 liters, depending on the number of cylinders. It is equipped with a compression ratio of 15:1 and a mean effective pressure (MEP) of 25.9/24.9 bar at 720/750 rpm. Common maintenance issues include turbocharger fouling, exhaust gas temperature imbalance, piston ring damage, cylinder liner scuffing, and fuel injection nozzle coking, all of which require regular inspection and timely intervention to ensure optimal engine performance and longevity.
