摘要
本文阐述了船用柴油机有害排放对大气污染的问题以及国际海事组织对船舶柴油机排放的控制要求；介绍了当前降低柴油机排气中ＮＯｘ、ＳＯｘ和颗粒排放污染的技术措施。在此基础上，讨论了各种措施的利弊、适用范围及今后应探讨的问题。
The paper deals with the air pollution caused by harmful gases from marine diesel engines and expounds the requirements made by IMO for controlling engine exhaust gases.It describes some of the prevailing technical measures to reduce NOx,SOx and particles contained in exhaust gases.The measures are then further discussed, focusing on their pros and cons,application area,and problemsremaining to be solved.
