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。
But because of reduced injection timing and increased exhaust back pressure, the BSFC of the engine will be increased of 8%.
但由于提前角减小，排气背压增大，发动机燃油消耗率上升8%左右。
The effect of back pressure on the weight precision in injection molding was investigated via experiments of injecting to air.
