| Abstract: | A new-typed flow control valve was introduced,which was used in high-pressure common rail system.The experiment of common rail pressure control was carried out and the influence of duty cycle on flow control valve performance was analyzed.The results show that the designed flow control valve can satisfy the requirements of common rail diesel engine in the aspects of control precision,which is in the ranges between 3 percent and 5percent,response speed,flexibility and system stability. |
