It shows that the effects of back pressure on penetration, sprayconeAngle, 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 results show that bright images used in gray scope can assure the measuring error scope within 5% of sprayconeangle and the measuring error scope within 1% of penetration distance.
