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
而且當壓力或密度較高時，由於噴霧的空氣卷吸量及動量損失增大，貫穿速度降低及貫穿距減小，為使bump發揮作用，應適當減小二次撞壁距離。
