PROBLEM TO BE SOLVED: To provide a device for controlling a cylinder injection-type internal combustion engine, which optimizes an end timing of fuel injection of a cylinder injection-type internal combustion engine to secure fuel atomization time and improve performance on exhaust emission.SOLUTION: The device for controlling an internal combustion engine includes: a fuel injection valve for injecting a fuel into a combustion chamber of the internal combustion engine; a fuel pump for pumping the fuel to the fuel injection valve; a fuel accumulation chamber for storing the fuel to be fed to the fuel injection valve; a device for detecting an internal pressure of the accumulation chamber; a control device for controlling the internal pressure of the accumulation chamber; and a control device for controlling an injection amount from the fuel injection valve. The device for controlling an internal combustion engine changes at least one of the internal pressure of the accumulation chamber, an air-fuel ratio, and an amount of intake air when the injection end timing comes after a specified crank angle. |
