fuel injection spray 燃油喷雾
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 quality of fuel spray is decided by the structure of nozzle and high-pressure fuel pipe in the pump-tube-nozzle fuel injection system, and it influences the whole diesel combustion.
