two-stage turbocharging

基本解释

As to the adjustable two-stage turbocharging system with bypass valve, it can make a further bigger pressure ratio so as to a further higher altitude of the engine.
带旁通阀的可调二级增压系统通过在低压级涡轮上增设旁通阀，可以使增压系统获得更大的压比输出，其临界海拔高度得到进一步提升；
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。
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。
