Abstract: Abstract The injector is one of the precision components for a diesel engine, and it is inevitable to wear fault during utilization. For the fault of the orifice expansion and the orifice obstruction, they are essentially changing the structure parameters. In order to analyze the effect of the orifices on injection performance, the simulation model of a certain type diesel injector was established based on AMESim. And a simulation for a whole injection cycle of this injector was performed, thus the injection characteristics and the relevant information about motion of the needle valve was obtained. The effect on the velocity of the needle valve, the flow rate and the volume of the fuel oil injection, etc. had been analyzed by changing the number, or the diameter of orifices, and setting different diameters for each orifice. The analysis would provide some references in structure design, optimization, testing data analysis and fault diagnosis.
