The physical structure of the electromagnetic system used for a pulsatory electromagnetic fuel injector is presented in this paper. The working characteristics of its electromagnetic system is analyzed through the basic theories of electromagnetic, mechanics and hydrokinetics. The contrast for its static characteristics between the theoretical computation result and testing result is also analyzed; the difference is small. So the theoretical data obtained has provided useful information for the controlling parameters and for the design and improving of the structural parameters of the pulsatory electromagnetic fuel injector.
