摘　　要：国际海事组织(IMO)的“限硫令”于2020年1月在全球范围内实施后,燃用低硫燃油(LSFO)成为许多远洋公司的主要选择。对多家远洋公司船舶主机燃用LSFO后的运行状况进行调研,发现缸套、活塞环等零部件存在异常磨损及故障显著增多的现象。将LSFO对船舶主机的影响以及其实际应用案例进行分析与总结,并针对燃用LSFO的主机所出现的异常磨损和故障现象提出应对策略。该研究有助于解决LSFO条件下船舶主机缸套和活塞环异常磨损问题的实际需求,希望进一步推动LSFO条件下缸套和活塞环异常磨损的机理研究。Since the IMO(International Marine Organization)enforced the"sulfur limitation order"for ship emissions in January 2020,the LSFO(Low Sulfur Fuel Oil)became the main choice for ocean shipping.In this paper,the operating conditions of main engines after burning LSFO were investigated by many ocean-shipping companies.It is found that abnormal wears and significant increases in failures occur in the cylinder liner,piston ring and other components.Then,the influences of LSFO on main engines are analyzed and summarized,as well as the practical application cases of LSFO applied to ships.Finally,the complementary strategies for the abnormal wear and failure phenomenon of the main engine burning LSFO are put forward.This paper is helpful in solving the actual demands of abnormal wear issues from cylinder liners and piston rings in main engines burning LSFO,and hopes to further promote the mechanism research of abnormal wear from cylinder liners and piston rings in main engines burning LSFO.
