| Abstract: | Dynamic pressure fluctuation inside common rail directly impaet achievement of inject-fuel rule in diesel engine highpressure common rail system eun＇ently. In this paper, the models of the common rail injection system are built with HYDSIM of AVL company, aiming at stabilizing pressure of common-rail inside and meeting start of system, and performed matching design of common rail pipe, and analyzed and calculated volume, length and diameter of high pressure common rail pipe. According to system requirement, calculated outer diameter of common rail pipe. |
