The model of solenoid valve injector in high pressure common rail system is presented. The model considers the influences of flow limiting valve, T type pipe and the pressure loss caused by fuel flow. The forms and positions of the pressure loss were determined. In the model the fuel density and elastic modulus are only viewed as the functions of fuel pressure. The results obtained by Simulink software were compared with experimental results in order to assess the model. Results show that the simulation error of the model considering flow limit valve and T type pipe influences to the experimental results is less than 6%, while the results without these considerations have larger difference from the experimental results. The simulation difference between the model that views fuel density and elastic modulus as constants and the model that views both of them as the functions of pressure is small. The errors of the two models to the experimental results are less than 6%.
