• Effect of Injection Rate Modulation on The Formation of Spray Structure

抄録

The effect of injection rate modulation on the spatial dispersion of fuel droplets and inner structure of fuel spray were investigated by high-speed sectional photographs of fuel spray. To obtain the injection modulation, an electronically controllable fuel injection system developed at this laboratory was used. Through the experiments ranging from OHz to 6.5kHz of modulation frequency, it was confirmed that the shape of spray with injection rate modulation became pulse like one from a specific modulation frequency. It is considered that the pulse like spray is the result of the catching up motion of the high velocity droplets crowd.
