该公式直接反映出关键参数与涡流损失的关系，据此提出了减少涡流损失的措施。
The formulation reflects the relation between the key parameter and the vortex loss, on the basis of which the measure of reducing vortex loss is carried out.
由于喷头中有了导流体，避免了涡流的产生与剪切层的分离，从而大幅度地减少了喷头的能量损失。
In the presence of the flow deflector, the generating of the vortices and the separating of the shear layer are avoided thereby the energy loss of the jet nozzle is reduced considerably.
同时，可以降低对进气涡流的要求，增加气门流通面积，减少流动损失。
Besides, the strength of the intake swirl can be less, that will increase valve area and reduce the loss of flowing. This combustion system also c...
