<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine capable of suppressing favorably a degrading of the adjusting accuracy of fuel injecting amount resulting from a temperature change of the fuel flowing in a fuel injection valve 24. <P>SOLUTION: The intra-INJ fuel temperature as the temperature of the fuel flowing in a high-pressure fuel passage is presumed on the basis of the time in which the fuel supplied from a common rail 18 stays in the fuel injection valve 24, an INJ inlet fuel temperature as the temperature of the fuel flowing into a fuel inlet port 40, a temperature of the fuel injection valve 24, etc. The fuel injecting amount from the fuel injection valve 24 is corrected on the basis of the presumed intra-INJ fuel temperature. The current feed to an electrically operated actuator 62 is controlled on the basis of the corrected fuel injecting amount. <P>COPYRIGHT: (C)2013,JPO&INPIT |
