Introduction of the Latest Mitsubishi UE Engine Technologies

抄録

Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME) has developed a new generation low-speed marine diesel engine, the UEC50LSH-Eco, for a wide output and speed range that includes the chemical tankers and Supramax and Handy-size Class bulk carriers and medium range tankers. The UEC50LSH-Eco has been developed on the principal design concepts of “high efficiency” and “environmental friendliness” and based on technologies accumulated from many years of technical development activities of Mitsubishi UE Engines. The UEC50LSH-Eco achieves extremely low SFOC (Specific Fuel Oil Consumption) owing to an improved trade-off relationship between SFOC and NOx obtained by an optimized fuel injection pressure and rate, reduction of mechanical loss, and high efficiency of the exhaust gas and scavenging air system. Moreover, further SFOC reduction can be achieved with Mitsubishi’s MET Turbocharger technologies. Recently, MHI-MME also released a new UEC-LSE series that includes the “UEC-Eco” electronically controlled engines, to comply with IMO-NOx Tier 2 regulations and market needs to save energy. All of these UE engines are in service and demonstrate excellent performance.
