configuration and performance comparisons were conducted between the regulated two-stage turbocharging system with an outside butterfly valve and the other one with an inside wastegate.
对带外置式蝶阀的二级增压系统和带内置式旁通阀的二级增压系统进行了结构和性能比较。
as the uav altitude increasing needs, the single stage turbocharging system can not meet it, so it is essential to do some deep research on the two-stage turbocharging system.
由于小型航空活塞式汽油发动机飞行高度日益提高的需要,单级增压系统已经不能满足要求,因此有必要对二级增压系统进行深入的研究。
in order to study the performances of two stage turbocharging system, the special two-stage turbocharging system test bench was set up and the compressor performance experiment was carried out.
针对重型车用、带有调节阀的可调二级增压系统的涡轮级进行了热力学分析,推导了涡轮级绝热效率的计算公式,给出了高、低压涡轮流量和膨胀比的计算方法。
