6L28/32H-GS-60Hz

Regular maintenance and diligent inspection are crucial for the reliable operation of marine engines like the MAN 6L28/32H-GS-60Hz, which is designed to handle heavy fuel oil and marine diesel oil with a power output of 1860 kW. This engine features a constant pressure turbocharging system with intercooling, ensuring efficient air intake and combustion. It operates at 900 rpm with a bore and stroke of 280 mm and 320 mm respectively, delivering 210 kW per cylinder at 720 rpm. The engine meets IMO Tier II and Tier III emission standards, with a compression ratio of 13.9:1 and a maximum combustion pressure of 130 bar. Common issues include charge air cooler fouling due to oil and water deposits, exhaust valve erosion from heavy fuel oil, and salt water corrosion in the cooling system. Regular checks such as monitoring charge air temperature, inspecting exhaust valves, and maintaining sacrificial anodes help prevent these issues. Additionally, bearing wear and fuel nozzle problems can arise over time, necessitating periodic inspections and replacements to ensure optimal performance and longevity.
