PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of suppressing increase of a particulate substance number (PN) while suppressing deviation of a cylinder fuel amount to a target fuel amount caused by shortage of a fuel adhesion amount to a wall surface of an intake port, by increasing a fuel injection amount.SOLUTION: Whether correction of a fuel adhesion amount on a wall surface of an intake port is executed or not is determined on the basis of information relating to an operating state of an internal combustion engine. When the execution of the correction of the fuel adhesion amount is determined, the higher an estimated value of a temperature of the intake port is, the more a fuel injection amount of a port injection valve is increased, and the lower the estimated value is, the more the fuel injection amount of a cylinder injection valve is increased. Preferably, in a case when the estimated value is a prescribed determination temperature or more, the fuel injection amount of the port injection valve is increased, but when the estimated value is lower than the determination temperature, the fuel injection amount of the cylinder injection valve is increased for the increase of the fuel injection amount of the port injection valve.SELECTED DRAWING: Figure 2 |
