Abstract：The electromagnetic structure model of electronic gasoline injector is established, then using the law of motionto the armature assembly and the changing course of the coil current within an injection pulse is analyzed combining with electromagnetic theory, and this confirms the consistency between the time of the armature assembly movement characteristic curve point appearing and the time of the coil current curve point mutating.By using this correspondence, anindirect measurement method of invalid injection time for an electronic gasoline injector is found, and a measurement system is developed.The result shows: the measurement results of this system for invalid injection time relative error of a variety of electronic gasoline injectors is less than 3%.
