Abstract :
The spray visual system of GDI injector was designed. The GDI injector driver based on L9707 droved the fuel injection into a constant volume chamber. The spray development at various injection pressures, ambient back pressure and at different injection durations was visualized and memorized by high speed camera. By the wall placed at various angle in the chamber, the impinging spray development was also visualized and memorized. The system had high sample frequency, wide applicability and nicety experiment data. The system could be used for combustion chamber design, injector and spark plug distribution.
