<P>PROBLEM TO BE SOLVED: To provide a device for controlling an internal combustion engine which preferably suppresses discharge of unburned HC and dilution of oil due to fuel adhesion to a cylinder wall surface while suppressing deterioration of drivability of an internal combustion engine. <P>SOLUTION: The device for controlling an internal combustion engine includes a fuel injection valve 12 that is provided with respect to each cylinder of a multicylinder type internal combustion engine and capable of directly injecting fuel into each cylinder. The device for controlling an internal combustion engine estimates a cylinder wall surface temperature Tbn for each cylinder, and then configures a setting so that a fuel injection amount Qvn that is injected into each cylinder to generate torque is reduced for a cylinder with a lower cylinder wall surface temperature Tbn relative to a cylinder with a higher cylinder wall surface temperature Tbn. When a difference ΔQvn between the largest value and the smallest value of the configured fuel injection amounts Qvn for respective cylinders is larger than a predetermined value ΔQvreq, the device for controlling an internal combustion engine corrects a fuel injection amount Qvn injected into each cylinder so that the difference ΔQvn is equal to or less than the predetermined value ΔQvreq. <P>COPYRIGHT: (C)2013,JPO&INPIT |
