摘要
以进气歧管压力传感器作为主充传感器的增压汽油机,基于次充模型,开发设计出进气歧管压力传感器压力不合理故障诊断策略。在进气歧管实测压力不合理情况下,及时诊断出故障,EMS切换至次充模型,保证发动机可靠运行。
Unreasonable fault diagnosis strategy of intake manifold pressure （IMP） sensor is developed depending on secondary charge model when IMP sensor is the main charge sensor onto gaso- line engine with boost control. Diagnosis function can detect unreasonable fault of IMP sensor reliably and switch to secondary charge model control in time to make sure engine running well still.
