中文摘要：
将整个燃烧室部件（气缸盖-气缸套-活塞组-润滑油膜）作为一个耦合体，在对耦合体进行三维传热数值模拟的基础上，利用分区求解、边界耦合法建立缸内工作过程与燃烧室部件的三维耦合计算模型，从而实现了缸内工作过程与燃烧室部件的耦合三维仿真模拟，以此考察燃烧室部件传热空间非均匀性对缸内燃油雾化的影响。结果表明：喷雾初期和中期燃烧室部件壁面温度的空间非均匀分布对燃油的雾化有一定影响，主要影响燃烧室底部空间和壁面附近区域；在喷雾后期，此时缸内气体温度主要取决于燃油的燃烧，壁面换热的影响本身就极小，故壁面换热空间非均匀性对燃油的雾化几乎没有影响。
英文摘要：
Combustion chamber components （cylinder head-cylinder liner-piston assembly-oil film） were treated as a coupled body. A coupled three-dimensional calculation model for in-cylinder working process and the combustion chamber components was built with domain decomposition and boundary coupling method, which adopts the coupled three-dimensional simulation of in-cylinder working process and the combustion chamber components. The influence of the space non-uniformity in heat transfer among com- bustion chamber components on in-cylinder spray is conducted. The results show that the space non-uniformity in heat transfer among the combustion chamber components has certain influence on fuel atomization at the initial and middle stage of spray, mainly in the bottom space of combustion chamber and near cylinder wall. At late stage of spray, the in-cylinder gas temperature is mainly dependent on fuel combustion, rather than on heat transfer of cylinder wall. Thus, wall temperature space no-uniform temperature distribution of combustion chamber components of wall space has little influence on spray.
