摘要
本文提供了两级涡轮增压发动机压比和膨胀比合理分配的计算方法.并且给出了涡轮增压器最佳设计参数的确定方法,指出了合理地控制 E_T 和 E_K 值能够改善两级增压发动机部分负荷性能.计算结果与国外公布试验资料吻合较好.
This paper suggests a method for caculating reasonable distribution of total pressure and expand ratio in two-stage turbocharging system,and gives a method for determina- tion of the optimal design parameters in the turbocharger.It points out that to control rea- sonably E_X and E_T value will improve the performance of partial load of the engine.It is shown that caculation results are in good agreement with those obtained in the test abroad.
