PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine capable of more accurately controlling fuel injection quantity on the basis of an output of a cylinder-inside pressure sensor. SOLUTION: Requirement illustrated engine torque IMEPobj is computed in response to engine speed NE and acceleration pedal operation quantity AP, and requirement illustrated fuel injection quantity MFobj is computed in response to the requirement engine torque IMEPobj. Illustrated engine torque IMEPact (expressed in the figure) is computed in response to detected cylinder-inside pressure PCYL, and relative parameters a and b are computed by using sequential statistic algorithm on the basis of the requirement illustrated engine torque IMEPobj and the illustrated engine torque IMEPact (expressed in the figure). Final command fuel injection quantity MFcmd is computed by correcting the requirement fuel injection quantity MFobj by using the relative parameters a and b. COPYRIGHT: (C)2005,JPO&NCIPI
