随着国Ⅲ排放法规在国内的实施,电控高压共轨技术在国产柴油机上得到了广泛的应用。该技术具有节能、减排,使柴油机工作更稳定等优点,现国内多数客车装备了Bosch或Denso的电控高压共轨柴油机。虽然电控高压共轨柴油机具有自诊断功能,可以通过故障指示灯或故障检测仪读取故障代码,但在实际工作中发动机会出现很多无故障代码的故障,这时就有必要通过读取发动机数据流来分析故障原因。发动机数据流可通过故障检 With the implementation of the national emission regulation Ⅲ in China, the common rail pressure-controlled technology has been widely used in domestic diesel engines. The technology has the advantages of energy saving, emission reduction and more stable diesel engine. Most domestic buses are equipped with Bosch or Denso electronically controlled high pressure common rail diesel engines. Although the electronic control of high-pressure common rail diesel engine has a self-diagnostic function, you can read the fault code through the fault indicator or fault detector, but in actual work the engine will appear many fault-free code, then it is necessary to read the engine Data flow to analyze the cause of the malfunction. Engine data flow through the fault check
