摘　　要：针对更为严苛排放法规与节能需求,使用天然气燃料替代传统石油燃料供给发动机燃烧是一种行之有效的方法,目前开发的部分船用天然气发动机借助控制策略和机体结构优化已能达到同等规格柴油机的功率且具有更低的排放水平,随着新技术的发展其节能减排的优势还将有进一步提升的空间。根据现有的主流天然气发动机技术特点与存在的问题,分析并总结了当前船用天然气发动机性能与排放优化技术进程。In view of stricter emission regulations and energy-saving requirements,it is an effective method to use natural gas instead of traditional petroleum fuel to supply the internal combustion engine.At present,severaltypes of the marine engine fueled with natural gas could reach the equivalent power of the diesel engine with same size and produce less exhaust emissions.With the development of new technology on the marine engine fueled with natural gas,the advantages of energy saving and emission reducing will be further enhanced.The progress in the performance and emission optimization technologies for the natural gas engine fueled with natural gas were analyzed and summarizedbased on the characteristics and existing problems of the mainstream technologies of the natural gas engine.
