摘要 采用数值模拟的方法对GDI系统喷油器燃油的流动状况进行了分析,通过设置不同的入口压力条件分析了油嘴内压力、速度、气穴的分布状况,指出了压力对喷油嘴流动状况的影响规律,为GDI系统的燃油喷射压力参数设置提供了参考依据。 The fuel injector flow in GDI system is analyzed by numerical simulation pressure, velocity, cavitation in nozzle is analyzed by setting the entrance pressure pressure on the nozzle flow condition is pointed out and it provides a reference set for the method. The distribution of conditions.The influences of GDI tirol injection system and pressure parameters.
