【摘要】 研究6V150柴油机有效能量利用情况,采用了发动机性能仿真软件与热力学分析相结合的方法.使用仿真软件BOOST建立了柴油机的仿真模型,并用实验所得数据和发动机的基本特性定义仿真模型的初始值,得出热力学分析所需要的数据;对柴油机的各个组成部分抽象为控制体进行热力学第一定律、第二定律计算,得出柴油机工作过程的损失分布规律,进而从热力学第二定律的角度提出改善柴油机能量利用的方向.更多还原

【Abstract】 In order to evaluate the efficiency of the diesel engine 6V150 based on the second law of thermodynamics, corresponding analyses are carried out by exergy loss calculations on a quasi-dimensional engine model built up in software package BOOST. On the engine model validated by experiment, the data desired by thermodynamic analysis for each component of the engine are computed by the code as an interface of the BOOST. Finally, characteristics of the engine exergy loss distribution are discussed and methods of improving the efficiency of the diesel engine are proposed.更多还原
