High-pressure common-rail fuel spray system has been widely used in disesel engine but monopolized by foreign countries now.On the basis of researching high-pressure common-rail fuel spray test bench,oil injection characteristic test was carried on to achieve basic lil spraying characteristics and characteristic test of common-rail pressure sensor which were analyzed to gain relation among common-rail pressure,spraying pulse width and distributive value,scavenger oil value,and characteristics of common-pressure sensor output,which lay a foundation to self-developed high-pressure common-rail system and its control unit.
