摘　　要：基于四冲程发动机的工作原理 ,用键合图对一四缸汽油机进行了建模。整个模型分为热力学部分和机械部分 ,机械部分的建模采用真键合图 (即功率键合图 ) ,热力学部分采用伪键合图。伪键合图的几种C元件和R元件根据其实际的物理特性并按照真键合图的习惯进行了定义 ,然后推导出整个系统键合图的 13个状态方程式 。Based on the working principle of the four-stroke engine, we model the four-cylinder gasoline engine using bond graph technique. The entire model is subdivided into mechanical and thermodynamic sections. The latter section is modeled with true bond graphs, i.e. energy bond graphs, while the former section with pseudo bond graphs. Some C components and R components are defined according to their physical properties and the true bond graph tradition. Thirteen state equations of the complete system are deduced, followed by the numerical simulation.
