基于故障树分析的电控汽油机无法起动的故障诊断

Fault diagnosis based on fault tree analysis of electronically controlled gasoline engine can not start

故障树分析法是一种将系统故障形成原因按树枝状逐级细化的图形演绎方法,常用于系统的故障分析、预测和诊断。对电控汽油机的启动控制分析,构建电控汽油机无法起动的故障树。根据底端事件出现的频度和工作对象的接近性,设计电控汽油机无法起动的故障诊断流程图。

The fault tree analysis is a system failure causes dendritic progressively refine the graphical interpretation of the method,the system commonly used in failure analysis,prediction and diagnosis.The start of the electronically controlled gasoline engine control analysis,fault tree to build electronically controlled gasoline engine can not start.According to the bottom of the incident frequency and the proximity of the object,the design electronically controlled gasoline engine can not start the troubleshooting flowchart.
