19满足美国第2阶段第5级排放限值的Bluetec排放控制系统显示文摘近年来,柴油机在欧洲轻型车的市场份额持续增长,而北美市场的柴油机份额却仍很小。直至最近,柴油机仍可不使用活性的氮氧化物(NOx)后处理系统,仅通过发动机机内优化措施就能满足欧洲和北美的Nox排放限值要求。但美国于2007年引入第2阶段(Tier2)第8级(Bin8)和Tier2第5级(Bin5)排放法规后,大部分新柴油机都将需要采用No,后处理系统。降低稀燃排气中NO:的一种可行技术是NOx吸附催化器,它是汽油直接喷射发动机的公认选择。Daimler公司已将其用于现行的柴油机BluetecⅠ系统。对于中重型汽车来说,尿素选择性催化还原(SCR)系统是满足NOx排放限值的首选技术之一。用于重型载货车的尿素-SCR系统已投入批量生产,并正将其开发用于大型客车,以满足美国Bin5法规。论述了满足Bin5排放法规的Bluetec排放控制系统的要求,包括柴油氧化催化器、催化型柴油颗粒过滤器和SCR催化器,也讨论了满足这些要求的方法,为此介绍了一些包括模拟气测试、发动机台架测试,以及车辆评估等在内的研究结果。 2011国外内燃机2011,43,1:0
