A mathematical model of the fuel metering system is established on the basis of the numerical analysis and with the help of MATLAB software.The law of variation of non-linear pressure coefficients is obtained,where the pressure distribution changes with the motion of sliding value.An optimized design of important parameters is made by the simulation model,effectively increasing the anti-jamming capability with the back pressure of engine combustion chamber.This model can be used as an important reference to the law of pressure distribution and its systematic study.The products of the design have passed the tests.
