ABSTRACT:
This paper is based on the background of China Undergraduate Mathematical Contest in Modeling Competition A in 2019. Corresponding analysis based on the data given in this question, calculated changes in pressure in the high-pressure tubing according to the different operating conditions for fuel entry and spewing out, in order to determine some operating parameters of the fuel injection system, so as to improve engine efficiency and economic efficiency. The differential equation is constructed by the mass conservation formula under the corresponding conditions, and using MATLAB to implement Runge-Kutta methods to find the numerical solution of the corresponding differential equation.
