In this paper,an injector of gasoline direct injection system is used as the research object. The electromagnetic finite element models of the solenoid valve of the injector are created with JMAG. The models are validated by test results. The affects of key construction parameters on its response characteristics are investigated using the simulation model. The optimization of driving voltage and key construction parameters is also discussed aiming at the improvement of its response characteristics. Via the analysis and simulating calculation,the theory base has been provided for the design of drive control and construction parameters on the injector.
