“数据流”在电控发动机故障分析中的运用

随着电控燃油喷射技术的发展和汽车维修水平的不断提高,使用故障诊断仪检测发动机电控单元(ECU)是判明故障可能发生原因和部位的有效方法。阐述使用故障诊断仪进行数据流的检测,通过研究发动机静态或动态数据状况,找出发动机实时数据流与实际参数的差异,确定故障所在,提出有效解决方案。

Application of data flow analysis in fault diagnosis of electronic control engine

With the development of EFI（Electronic fuel injection） and the rising of vehicle maintenance,The basic faults of the engine and the cause productive of them can be ascertained with the help of the fault diagnosis instrument by detecting engine ECU.In this paper,using the instrument detects dataflow,the abnormalities of the engine real time dataflow and the actual parameters are found by studying the engine state of the static and dynamic data.The fault is confirmed and thus the effective solutions are proposed.
