For injection timing, the fuel movement is controlled by the intensity of the vortex I. For injection duration, the fuel movement is controlled by the value of jet flux. The ideal fuel distribution at ignition timing for high combustion rate is studied. The optimal injection strategy had an increase in the peak pressure and NO emissions.
