| Abstract | High-Pressure Common-Rail Fuel Injection System is the most common technique of fuel injection used in diesel engine of automobiles. High-Pressure Common-Rail Fuel Injection System refers to a new method of fuel supply which can entirely separate the process of generation of inject pressure and the process of fuel inject under the control of a close-loop system which contains high-pressure oil pump, pressure sensor and electronic control unit. During the working process of diesel engine, the time of injection is extremely short which costs only a few milliseconds due to the high rate of rotation of the engine, meanwhile, in the process of injection, the pressure of every point of the high-pressure oil pipe is fluctuated with the change of position and time. Besides, because of the compressibility of diesel itself, the real situation of fuel injection is quite different from the regularity of fuel supply of the ram pump controlled by high-pressure fuel pump. What’s more, the fluctuation of pressure in high-pressure oil pipe may also cause secondary injection which will sharply reduce the performance of emission and economy. If the unusual injection is severe, it may not only cause the non-uniform of fuel injection but also lead to a phenomenon of intermittent inject failure. The engine equipped with common-rail technique can effectively solve these defects that traditional engine may have. |
