Experimental study on the injection characteristics of a dimethyl ether injector driven by electromagnetic force directly

• 摘要：

  The study is based on FJ-600 pilot injection measuring system. It is found that the injection quantities increase with the fuel injection pressure's decrease or the back pressure's increase in some working conditions, which would affect the fuel supply accuracy and engine performances. This is because the needle movements are affected by the fuel pressure and back pressure directly, the injector's effective flow section and real injection duration change obviously. Increasing the spring stiffness and electromagnetic force will be of benefits to improving the injector's injection characteristic.
