7LH32/40 DF

The HiMSEN 7LH32/40 DF engine operates on a 4-stroke, turbocharged, and Miller Cycle design, optimized for dual-fuel operation with both LNG and Heavy Fuel Oil (HFO). This robust engine delivers a power output of 3080 kW at 720 rpm, featuring a bore of 320 mm and a stroke of 400 mm across seven cylinders. Designed for marine applications, the engine ensures high efficiency with a compression ratio of 15:1, achieving a mean effective pressure of 25.9 bar at 720 rpm. It incorporates advanced features such as a specific fuel oil consumption of 179 g/kWh and a specific lubricating oil consumption of 0.7 g/kWh. Common maintenance checks include inspecting the turbocharger for fouling and carbon deposits, verifying the exhaust gas temperature balance between the A-bank and B-bank, and monitoring for piston ring wear and cylinder liner scuffing. Regular checks of fuel injectors for coking and carbon deposits are also crucial to maintain optimal performance.
