同时经常怠速行驶，进入发动机的空气流量也就小，这样对积碳的冲刷作用变得也很弱，会促进积碳的沉积。

At the same time often idle speed, the air flow into the engine is small, so that the carbon flushing action becomes also is very weak, will promote carbon deposition.

由于航空发动机转速高，空气流量大，排气温度高，试车时产生的强烈噪声形成大范围的环境污染；

Aerogine has the features of high rev, heavy air flux and high exhaust temperature, fierceness of noise engenders environment pollution largely during aeroengine test.

航空生产商和他们的供应商要求高质量的通道空气流量计量，用于航天和陆地涡轮发动机组件。

Aerospace OEMs and their suppliers require quality air flow measurements of passages in both aircraft and land based turbine engine components.
