摘　　要：船舶发动机虽然以较高的热效率被广泛应用,但其向海洋环境排出了大量的污染物。近年来,随着针对海上船舶的排放法规日益严格,能显著降低远洋船舶NOx、SOx、PM和CO2排放的天然气发动机逐渐引起关注。从船用天然气技术发展和分类入手,针对不同的技术路线出现的问题,总结了当前船用天然气发动机研究进展。Marine engines, although known for their high efficiency, discharge substantial emissions into the environment. With the increasingly strict emission regulation, the growing demand to reduce emissions has led to interest in engines fueled by natural gas in recent years, which can significantly reduce nitrogen oxides, sulfur oxides, particulate matter and carbon dioxide. This article, starting with the development and category of natural gas technology in marine engines, summarizes the current research progress based on problems occurring in different technology routes.
