<P>PROBLEM TO BE SOLVED: To provide a fuel injection device and a fuel injection system in which the injection state of a fuel injection valve is finely and accurately controlled. <P>SOLUTION: This fuel injection device comprises an injector 20 (fuel injection valve), a pressure sensor 20a which is disposed in a common rail (accumulation container) on the side nearer an injection nozzle and which detects a fuel pressure, and an IC memory 26 (storage means) in which individual difference information indicating the injection characteristics of the injector 20 obtained by tests is stored. The individual difference information stored in the IC memory 26 is the information indicating the relation between the state of injection in which a fuel is injected from the injector 20 and a variation in the pressure detected by the pressure sensor 20a occurring due to the injection. <P>COPYRIGHT: (C)2009,JPO&INPIT |
