Controllable Filling Technology Relied on Micron Fill-tube

The temperature gradient was employed to inject the fuel under control based on the fuel reservoir and the target chamber temperature controlling respectively, and the filling technology feasibility was verified by using a 5 μm diameter fill-tube. Additionally, influences of initial filling pressure, target chamber and fuel reservoir temperature on the filling processes were discussed. The experiment results indicate that the injection rate can be controlled by adjusting the fuel reservoir temperature when the initial filling pressure is 86 kPa and the target temperature is 19.5 K.
