Examples
- The burning gases can ignite the lean mixture .
燃烧着的气体能点燃稀的混合气。 - The engine will not run well with a lean mixture and may stumble or stall .
使用稀薄的混合气，发动机将不能很好地运转，并会出现加速后坐现象或失速停车现象。 - The carburetor delivers a rich mixture to the precombustion chamber and a lean mixture to the main cylinder .
化油器将浓混合气输至副燃烧室，将稀混合气输送至主气缸。 - The bump height and secondary wall - impingement distance were discovered to play an important role in producing a secondary space jet , reducing the quantity of fuel stuck on the wall and forming lean mixture , and their suitable values being 1 . 0 - 1 . 5mm and 0 - 2 . 0mm respectively
发现bump高度及二次撞壁距离对撞壁油束形成二次空间射流、减少壁面燃油堆积以及形成稀混合气有重要作用，且发现bump的高度和二次撞壁距离分别为1 . 0 1 . 5mm和0 2 . 0mm比较合适。 - Moreover , the secondary wall - impingement distance should be properly reduced in order that the bump play a part in the formation of lean mixture with the increase of environmental pressure or density owing to both the increase of air entrainment , momentum losses and the decrease of the spray tip velocity and penetration
而且当压力或密度较高时，由于喷雾的空气卷吸量及动量损失增大，贯穿速度降低及贯穿距减小，为使bump发挥作用，应适当减小二次撞壁距离。
