摘　　要：本文提出一种工程上可实现柴油机最佳放热规律的研究方法。即以零维工作过程计算为基础，将柴油机整个工作过程当成一个动态的热力学系统，由整个动态系统的最优匹配来辩识燃烧子系统的最优动态响应，获得柴油机的最佳放热率及最佳经济性与动力性，从而为现有机型的改进潜力找到一种全新的判断方式。同时，应用这种方法，对某一中速大功率柴油机进行了实例优化计算。A kind of research method for realising the optimal releasing heat of the diesel engine is put forward in this paper in the engineering.I.e.on the basis of the Z-D cycle calculation,the total cycle of a diesel engine is regarded as a dynamic thermodynamic system,the optimal dynamic response of the combustion subsystem is identified by the optimal mating of the total dynamic system, and the optimal releasing heat, fuel economy and power output of the diesel engine are obtained.A new judgement method improving the existing diesel engines is got by the investigation.In the same time,the practical calculation is carried out in respect to a high output medium speed diesel engine using this method.
