曼恩和瓦锡兰船用二冲程双燃料发动机之比较

摘要

为加深对曼恩和瓦锡兰船用二冲程柴油-天然气双燃料发动机的了解,帮助船舶选择机型,文章从工作原理、燃气系统、点火油、尾气排放、经济性和安全性等方面对两机型进行比较,发现曼恩发动机在经济性和安全性方面稍具优势,但尾气排放方面却不如瓦锡兰环保.%This paper makes a comparison of the two-stroke dual-fuel marine engine between MAN and W?RTSIL? from the working principle, gas system, ignition oil, emissions, and safety, etc. It will deepen understanding of the engine and provide references for the marine engine selection. It shows that the MAN engine has slightly better economy and safety, but worse environment-friendly performance in exhaust emission than the W?RTSIL? engine.
