废气涡轮增压与发动机匹配的理论计算研究

Study on Theoretical Calculation of Matching of Turbocharger and Engine

根据废气涡轮增压的工作原理、结构特性,对增压器和发动机的空气流量和其他方面的匹配进行了计算和理论分析,提出了发动机选配增压器的基本过程和注意事项,以及重新为指定发动机设计增压器的基本步骤。

Based on operating principle of turbocharger,structural features,air flow characteristic and other aspects of turbocharger and engine are calculated and analyzed theoretically.The current process was raised for the matching of turbocharger and engine.Accordingly the basic procedure was redesigned for the designated engine.
