8LH35/40DF

This marine engine operates on a dual-fuel principle, utilizing both LNG and HFO, designed to meet stringent emission standards while providing robust performance. The HiMSEN 8LH35/40DF is a powerful 8-cylinder, 4-stroke engine with a bore of 350 mm and a stroke of 400 mm, capable of generating 4000 kW at 720 rpm. It is optimized for marine applications, ensuring efficient combustion and low fuel consumption. The engine features enhanced Miller timing for NOx compliance and a new generation turbocharger, enhancing overall efficiency. Specifications indicate a specific fuel oil consumption (SFOC) of 177 g/kWh at 100% maximum continuous rating (MCR) and 174 g/kWh at 85% MCR. Maintenance guidelines highlight the importance of regular inspections for cylinder cover wear and water contamination in the crankcase, which can lead to acid formation and bearing wear. Additionally, the engine requires periodic cleaning of the turbocharger compressor and turbine to prevent wear and tear, typically every 200 to 500 operating hours.
