摘　　要：从对共轨喷油器机械过程和液力过程的机理研究入手,总结出影响其液力过程的主要特性值,在机理分析的基础上,对喷油器3个部位处的液压力进行试验,对其液力过程进行了研究和分析,通过试验,比较节流孔参数,控制腔结构,针阀限位方式等因素对喷油器液力过程的影响,总结得到喷油器液力过程的主要影响因素,并为提高喷油器的喷射精度,响应性能等提出了相应的建议。With the mechanism study on mechanical and hydraulic process of the common rail injector,it is summarized that the key characteristics of its hydraulic process value. On the basis of the mechanism research,hydraulic pressure has been measured and analysed on three locations of the injector. To compare the hydraulic process with different structure and parameters of the injector,it can be concluded which is the major factor in injector＇s hydraulic process finally. Some suggestions are thrown out to improve the precision and responsiveness of injector＇s injection at the end of the paper.
