Abstract:
1. A control device of an internal combustion engine including a first fuel injection mechanism for injecting fuel into a cylinder, and second fuel injection mechanism for injecting the fuel into an intake manifold, and being configured to execute purge processing of fuel vapor, comprising: control means for controlling the fuel injection means to inject the fuel by sharing the injection between said first fuel injection mechanism and said second fuel injection mechanism according to conditions required in said internal combustion engine; and purge control means for controlling the fuel injection mechanism to correct a fuel injection amount corresponding to an introduced purged fuel amount during execution of said purge processing by sharing the correction between said first and second fuel injection mechanism, wherein said purge control unit controls the fuel injection mechanism such that a ratio of the fuel injection amount of said first fuel injection mechanism with respect to a whole fuel supply amount does not change in a region of the fuel injection shared by said first and second fuel injection mechanisms.
