two-stage turbocharging

基本解釋

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(diào)二級(jí)增壓系統(tǒng)通過(guò)在低壓級(jí)渦輪上增設(shè)旁通閥，可以使增壓系統(tǒng)獲得更大的壓比輸出，其臨界海拔高度得到進(jìn)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.
對(duì)帶外置式蝶閥的二級(jí)增壓系統(tǒng)和帶內(nèi)置式旁通閥的二級(jí)增壓系統(tǒng)進(jìn)行了結(jié)構(gòu)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(duì)重型車用、帶有調(diào)節(jié)閥的可調(diào)二級(jí)增壓系統(tǒng)的渦輪級(jí)進(jìn)行了熱力學(xué)分析，推導(dǎo)了渦輪級(jí)絕熱效率的計(jì)算公式，給出了高、低壓渦輪流量和膨脹比的計(jì)算方法。
