摘要 介绍了通过涡轮增压系统结合发动机机内技术来实现IMO Ⅲ排放标准的技术及解决方案。在IMO Ⅱ排放水平的基础上通过机内技术进一步降低NOx排放需要采用极强的米勒定时,因此需要较高的增压压力即两级涡轮增压,同时结合VCM(气阀控制系统)、紧凑型SCR系统或EGR等技术方法来实现IMO Ⅱ。IABB的研究发现,两级涡轮增压系统具有同时降低油耗与NOx的潜能,并且具有运行灵活性等优势。 The technologies and solutions which combines turbocharging system and in-engine technologies to realize IMO Ⅲ emissions regulations are introduced.Based on IMO Ⅱ emissions level,strong Miller timing is necessary for further reduction of NOx emission with in-cylinder technology,therefore,higher charging pressure,which means two-stage turbocharging should be adopted,together with VCM,compact SCR system and EGR to realize IMO Ⅲ.ABB research shows that two-stage turbocharging could reduce both fuel consumption and NOx emission and has the advantages of operational flexibility.
