摘要
目前,重型柴油车SCR系统的车载诊断是SCR系统应用到车辆排放控制中的难点和研究热点,介绍了SCR系统的工作原理,阐述了在重型车上加载车载诊断(OBD)系统的必要性及其发展现状,分析了目前国外SCR车载诊断系统研究的现状以及存在的问题,论述了今后的发展方向。
Currently,SCR on-board diagnostic of the heavy-duty diesel vehicle is the difficult point and research high light of applying SCR on the vehicle emission control.This paper introduces the operating principle of SCR;illustrates the necessity and development situation of heavy-duty on-board diagnostic.And then,analyses the research situation and existing problem of foreign SCR on-board diagnostic,discusses the developing direction of SCR OBD.
