Abstract
By an integrated numerical-experimental approach, the injection characteristics of a production high pressure common rail solenoid injector were investigated on kinds of control parameters include rail pressure and energizing time. The characteristics of injection quality, injection rate, needle opening and closure delays, injection temporal length were summarized via experiment carried out on a test bench. A model of high pressure common rail injection system based on AMESim was used to calculate simulation results, compare and approve the experimental injection data. The injector hydraulic process and lift process of needle were simulated and analyzed. The mechanism and rules of injection characteristics depending on rail pressure and energizing time were summarized.
