And new viewpoints about the adjust of the fuel delivery advance Angle and fuel-injectionpressure were put forward under the condition of plunger wear.
最后就柱塞副磨报后供油提前角和喷油压力的调整策略提出了新观点。

There are three parameters of fuelinjection system: response pressure, injection-advanced angle, injection valve bulge high degree, the best match was found by adjusting them.
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 fuelinjectionpressure.
