【Abstract】 A simulation model based on the theory of magnetic field and the mathematical solution method are developed to optimize the structure and the parameters of the fuel injector magnetic system(FIMS) used in the high pressure common rail fuel injection system of diesel engine. With the model, the simulation results are compared to the measured results, the response of the magnetic system is analyzed. The model has high predictive precision, can be used to design the FIMS, and the drive signal from the ECU.更多还原
