The carrier gas is supplied to the instrument at constant pressure from a cylinder. 載氣一般由壓縮鋼瓶供給，并要使載氣壓力恒定。
On the right hand side of the instrument panel, there is a display that indicates boost pressure, water temperature and fuel level. 在儀表板右邊有一個(gè)指示增壓壓力水溫和油位的顯示器。
The system can get very high supercharging pressure when the speeds of the two stage turbochargers are rather low, which ensures the system's security and reliability. 兩級增壓器轉速較低時(shí)能達到很高的增壓壓力，保證了系統的安全性與可靠性。
