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.
帶旁通閥的可調二級增壓系統通過在低壓級渦輪上增設旁通閥，可以使增壓系統獲得更大的壓比輸出，其臨界海拔高度得到進一步提陞；
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.
對帶外置式蝶閥的二級增壓系統和帶內置式旁通閥的二級增壓系統進行了結搆和性能比較。
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.
針對重型車用、帶有調節閥的可調二級增壓系統的渦輪級進行了熱力學分析，推導了渦輪級絕熱傚率的計算公式，給出了高、低壓渦輪流量和膨脹比的計算方法。
