【摘要】 高压共轨柴油发动机在欧洲发展较为普遍,近几年在国内发展十分迅速,但由于电控高压共轨柴油机普遍采用了高达180 MPa以上的压力和时间控制方式,目前国内对高压共轨柴油机教学设备开发较少。仿真实验台通过设计开发电控高压共轨柴油机线路故障设置装置、信号模拟装置及数据采样系统,实现多点采样,实时编程及对共轨柴油机喷射故障的控制;较好地仿真了高压共轨柴油机的实际故障重显功能,以更好地为电控共轨柴油机课程故障诊断分析的培养创造实训条件。更多还原

【Abstract】 High pressure common-rail diesel engine is very poplar in Europe. And it is developing very quickly in China in recent years. However, the development of training device for high pressure commonrail diesel engine is very seldom in our country because electrically controlled high pressure commonrail diesel engines all adopt time control mode and their work pressures are more than 180 MPa. A simulation training platform for electrically controlled high pressure common- rail diesel engines was developed in this paper. It mainly consists of circuit failure set device, signal simulation device and data sampling system. Based on these, this simulation training platform can realize multi point sampling, real time programming, and control the injection failure of common-rail diesel engine. It can simulate the actual failures of high pressure common- rail diesel engine well and display them. This simulation training platform provides the device foundation for electrically controlled common-rail diesel engine course in better training the failure diagnosis and analysis ability.更多还原
