First, an overall analysis of the system is performed to determine the pressure balance conditions of the high-pressure fuel pipe; that is, the mass of fuel flowing out of the high-pressure fuel pipe is equal to the mass of fuel flowing in. This article uses Excel to fit and organize the data in all data processing. When solving differential equations of pressure and density, the fourth-order Runge-Kutta formula is used, and the numerical solution is obtained by MATLAB2017a. %K Fuel Pressure %K 4th Order Runge-Kutta Formula %K MATLAB2017a %K Approximation Method %U http://www.oalib.com/paper/5434403
