介绍了一种柴油机电控喷油器喷射开启控制系统.为实现柴油机电控喷油器的开启、持续喷油、关闭功能,应用STC12系列单片机构成电控喷油器的控制系统.开启时为使喷油器开启迅速,应用单周期控制技术的IR1150S芯片,产生高压为112 V的高压电源为喷油器供电.试验结果表明,开发的柴油机电控喷油嚣控制系统符合X光相衬成像技术研究柴油机喷雾雾化机理的要求,喷油开启迅速、喷油持续稳定、关闭干脆.本系统根据设定可实现电控喷油器的单次及多次连续开启,进一步可以推广应用于柴油机喷油器相关环节教学实验中.%This paper described a control system of diesel electronic control fuel injector, which can achieve the opening, continuous injection and closing of electronic fuel injector with STC12 MCU control system. For the quick opening,one cycle control technique IR1150S chip was supplied to produce 1 12 V high voltages for injector. The experimental results show that the electronic controlled spray system can meet the requirements of diesel spray atomization research with X-ray phase contrast imaging technology. For the control system, the spray starts rapidly, injects steadily and closes immediately- According to the device sellings,this system can achieve single and multiple opening. This system also can be used in the. Diesel nozzle experimental teaching.
