The technology uses deep penetration perforation charge with high perforation density and large perforation diameter and surging perforation with greater pressure differential.
It shows that the effects of back pressure on penetration, spray cone Angle, and decline rate of centerline velocity and concentration of the spray are greater than that of fuel injection pressure.
背压对贯穿距离、喷雾锥角、喷雾轴心速度和浓度衰减率的影响均大于启喷压力。

The pressure wave penetration and reflection properitics at a valve, which is located in a conduit, are discussed, And the Penetration and reflection coefficients are derived.
