摘要
发动机二次空气喷射系统是一种新型的排气净化装置,它利用空气泵将新鲜空气经空气喷管喷入排气管或催化转化器,使排气中的CO和HC进一步氧化或燃烧成为二氧化碳(CO2)和水(H2O)。通过探讨二次空气喷射系统的结构原理、故障现象,掌握二次空气喷射系统的检测与维修。
The secondary air injection system of engine is a new type of exhaust-purified equipment. With air pump, this system ejects new air into exhaust tube or catalytic converter to convert CO and HC into CO2 and H2O. The structure and principles of secondary air injection system are discussed as well as its recondition.
