It shows that the effects ofbackpressure on penetration, spray cone Angle, and decline rateof 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。

At present heat rate calculate of the double backpressure turbine is according to single backpressure turbine, which brings deviation of heat rate calculate.
目前双背压汽轮机是按单背压汽轮机来进行热耗率计算的，由此带来热耗率计算的偏差。

The regenerating process of the DPF system was proven effective through controlling the exhaust flow rate and the backpressureof regeneration point.
