摘　　要：发动机工作过程的研究不仅是车辆的研究重点方向之一，而且也是热能动力机械行业的研究重点之一。定容燃烧模拟器可以实现对发动机的定容加热燃烧过程的研究。文章就所研究的定容燃烧模拟装置的结构组成、功能和工作原理进行了论述，该结构主要由气源、定容燃烧弹体、燃料／空气混合器、混合气配给系、点火系、控制系统和数据采集等系统组成。可以实现对定容燃烧过程边界条件精确控制，剔除点燃式发动机定容加热过程中众多杂乱影响因素，从而清晰地反映出燃烧过程及其影响因素的作用。The study of engine working process is one of key researches not only in the field of vehicle, but also in the fields of thermal dynamics. By means of the simulation device, the isochoric combustion in engines can be studied. The structure, function and working principle of the designed simulation device for the isochoric combustion are described. This device is mainly composed of gas source, isochoric combustion bomb, fuel/air blender, mixture allocate system, spark ignition system, control system, data acquisition system, etc. The boundary condition of the isochoric combustion process can be precisely controlled. And the disadvantageous influence on the isochoric combustion of the engine is avoided. Therefore, the combustion process and the factors of the influence on it can be clearly found.
