| Abstract: | A constant volume bomb(CVB) with high back pressure and wide visualization which can be used for spray experiment was presented.Using this CVB,the key datas affecting spray characteristics,such as back pressure,air temperature,oil pump speed,injection pressure,can be acquired and displayed on the data acquisition and control panel.In order to realize the single injection with constant pulse,the position of stop fuel lever of oil pump was controlled by using rapid electromagnetic valves.The experimental resu... |
