Main Engine 4-Stroke · Main Engines (4-Stroke)
This engine is commonly found in large vessels where reliable and efficient propulsion is essential, operating in marine environments that can be harsh and demanding. The HiMSEN 8L H35/40 is a 4-stroke engine with a compact and cost-effective design, featuring eight cylinders, each capable of producing 1250 kW of power. It is designed to run at a maximum continuous rating of 5680 kW at 720 RPM. The engine complies with IMO Tier II emission standards and can operate on MDO or MGO fuel types. It boasts a compression ratio of 17:1 and a maximum combustion pressure of 200 bar, enhancing its operational efficiency. The engine incorporates an enhanced Miller timing for NOx compliance and a new generation of turbochargers that offer higher efficiency. Regular maintenance is critical, particularly regarding cylinder cover wear and surface corrosion, water contamination in the crankcase lubricating oil, and abrasive particle wear on piston rings and bearings. Additionally, the turbocharger requires water flushing every 200 to 500 operating hours to prevent wear and tear.
