| Abstract: | The working principle of electronically-controlled injector is illustrated. Physical model and mathematical model are established. An arithmetic for flux-coefficient which affects veracity of simulation is given. With provided boundary conditions, emulator is designed. With an emulator,the relation between parameters of injector and characteristics of the dynamic response has been found out. A key parameter,the inlet and outlet diameter of the injector, that greatly affects the injector dynamic response has been ascertained. A test equipment of electronic injector response, has been set up, by which the result of the simulation is approved. |
