通过分析缸内热力过程，建立柴油机燃烧冲程微分方程。基于MATLAB工作软件实现柴油机燃烧过程仿真。其中，柴油机结构及运行参数可根据实际需要修改；传热系数的计算采用埃歇尔伯格公式；微分方程求解采用四阶龙格-库塔方法，计算步长为5度曲轴转角（可修改）；采用单韦伯曲线模拟燃烧放热规律；仿真结束后，绘制燃烧过程P-V图和P-phi图。(By analyzing the cylinder thermodynamic process, the establishment of diesel combustion stroke differential equations. Based on MATLAB working diesel engine combustion process simulation software. Among them, the diesel engine structure and operating parameters according to the actual needs modification heat transfer coefficient calculated using the formula 埃歇尔伯格 differential equations solved by Runge- Kutta method to calculate the step is 5 degrees crank angle (modifiable) single Webber curve simulation combustion Law after the simulation, drawing the combustion process PV diagram and P-phi diagram.)
