摘要
介绍了采用SCR技术路线达到国Ⅳ排放柴油机的OBD实现方法。发动机和SCR系统由发动机电控单元(ECU)和SCR电控单元(DCU)分别控制,提供了一种实现OBD的解决方案。
OBD is required for all China IV compliant engines. An OBD strategy is designed for SC9DF engine,a China Ⅳ compliant engine with SCR system. The fuel system and SCR system of the engine are designed to be independent and controlled by engine control unit （ECU） and SRC control unit （DCU） respectively,which proves to be a practical solution for the implementation of OBD.
