| Abstract: | The AMESim calculation model of the common rail injector has been established in this paper and sensitivity analysis of important parameters affecting common rail injector performance was finished by using MonteCarlo method.Under different conditions, the impact of armature lift,flow rate of the inlet orifice and outlet orifice,angle difference between needle and needle seat,flow rate of the nozzle hole,spring force and spring stiffness on the injector performance,such as the injection quantity,has been studied.The fluctuation range of fuel injected and the regression coefficients of the parameters in common rail injector were obtained. |
