摘要
探索了某涡轮增压柴油机排气能量中可用能的分布情况。使用GT-Power仿真软件建立了发动机的整机仿真模型,通过仿真计算得到排气系统各测点的热力学参数,采用热力学第二定律的分析和量化了发动机排气过程和涡轮膨胀过程中的可用能损失,分析了可用能损失的原因,并提出了这两个过程的耦合参数。
In this paper,the exergy distribution of exhaust system of a turbocharged diesel engine was explored.Firstly,a simulation model of the engine was constructed by using of software package GT-Power and the thermodynamic parameters of measure points were obtained by computational simulation.In addition,exergy loss in exhaust process of diesel engine and expand process of turbine were researched by the second law of thermodynamics method,Corresponding the reason for exergy loss were also analyzed and the estimative parameter coupled with two processes above was put forward eventually.
