Measuring cylinder is used on test bench of fuel injection pump all over the world , so manufacture error , sight error etc make the accuracy degree low . the thesis analyses the problem of fuel measurement system of the test bench of fuel injection pump , and the experiments and designs are done according to the problem , and the type and situation of the test bench of fuel injection pump all over the world is refered to 目前国内外喷油泵试验台量油系统普遍采用量筒式计量法,该方法存在量筒的制造误差、沉积误差、液面读数误差、气泡误差、挥发误差以及测量人员的视觉误差等,使得测量精度较低、耗时长,已不能满足对汽车发动机的环保技术要求和节能要求。
