摘　　要：基于高压共轨电控柴油机分析了柴油机电控单元故障诊断系统的工作原理,结合车载故障诊断系统的国际标准和电控系统模块化的设计思路,提出了针对各子模块的故障诊断控制策略,并完成了故障诊断模块的设计。通过对主要应用参数的标定,利用ETAS公司的ASCET软件实现控制策略的模拟仿真并在某型号高压共轨柴油机上进行台架试验。试验结果表明:采用控制策略可有效地实现柴油机的故障诊断。Analyzed the working principles of the fault diagnosis system for electron-controlled high pressure common rail diesel engine and based on the international standards of on-board diagnosis system and the modularizing design idea of electrical control system,the fault diagnosis control strategies for sub-modules were presented and used for its module design.The control strategies were simulated using ASCET software of ETAS,by calibrating main applied parameters and by bench test of a high pressure common rail diesel engine.The results show that the objective of the engine fault diagnosis is fulfilled effectively by adopting above control strategies.
