Based on the FTA of Electronic-Control Engine Start Fault Diagnosis Analysis

Abstract

Based on the analysis and the induction of electronic control fuel injection engine common failure which can't start, and according to the engine’s working principle and failure mechanism, established the electronic control fuel injection engine’s fault tree, and having made qualitative analysis about the working reliability of the engine by using the fault tree analysis method. This paper offered the electronic control fuel injection engine’s failure form which can’t start in classification, discussed the process of establishing the fault tree at length, even built and mapped the engine’s fault tree which can’t start; According to the natural gas compressor’s fault tree diagram, and applying the descending method to get the fault’s minimal cut sets. By making qualitative analysis, finding out the main influence factors of failure, and putting forward quite perfect methods of removing fault, which providing electronic fuel injection engine maintenance with the beneficial reference.
