<P>PROBLEM TO BE SOLVED: To provide a fuel injection condition analyzing device to improve the arithmetic processing efficiency for the analysis of an injection condition. <P>SOLUTION: The fuel injection condition analyzing device is applied to a fuel injection system provided with: a fuel injection valve 10 for injecting the fuel having a pressure accumulated by a common rail (accumulation container); and a fuel pressure sensor 20 arranged in a fuel passage from a discharge port of the common rail up to an injection hole of the fuel injection valve and detecting the fuel pressure. Also, the fuel injection condition analyzing device includes an injection rate parameter calculation means 31 (analysis means) for analyzing the fuel injection condition based on the variation of the detected value of the fuel pressure sensor 20 accompanying the fuel injection. In the fuel injection condition analyzing device, the analysis by the injection rate parameter calculation means 31 is intermittently executed without continuously executing for each injection when the fuel is sequentially injected from the fuel injection valve 10 of each cylinder. <P>COPYRIGHT: (C)2012,JPO&INPIT |
