This is made possible by the variable intake system with a throttle valve enlarged from 76 to 82 millimeters, the optimized cylinder heads and an exhaust system with low backpressure.
这是可能的变量与节流阀进气系统增加到76到82毫米、优化缸盖和排气系统压力较低。

High delivery lift and high backpressure required in fuel throttle valve test were obtained through higher rotation speed of the main pump.
利用长征系列发动机主泵作为动力源,提高其转速,解决了燃料节流阀试验要求的高扬程、高背压等技术难题。

It can also be used as a second stage separator and hold a constant backpressure by using its automatic pressure control valve on the gas outlet.
