| Abstract: | The method of fault tree analysis(FTA)is applied to analyze the trouble of unsteady idle speed of EFI engine. All kinds of possible reasons and their combined forms causing this trouble are presented,and the qualitative analysis and quantitative analysis are done. Base on the minimal cut sets got by fault tree qualitative analysis,it is convenient and quick to find the bottom event faults that let to top event,thus providing the analysis method for the automobile serviceman on processing this typical fault. |
