Abstract:
1. A control device of an internal combustion engine including a first fuel injection mechanism for injecting fuel into a cylinder, and a second fuel injection mechanism for injecting the fuel into an intake manifold, and being configured to execute purge processing of fuel vapor, comprising: a control unit for controlling the fuel injection mechanisms 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 a purge control unit for controlling the fuel injection mechanisms 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 mechanisms, wherein said purge control unit corrects the fuel injection amount corresponding to the introduced purged fuel amount by causing the fuel injection mechanisms to share the correction according to a sharing ratio between said first and second fuel injection mechanisms, and said purge control unit performs control such that a basic fuel injection amount corresponding to the sharing ratio of each of said first and second fuel injection mechanisms is reduced by an amount depending on the sharing ratio and a fuel injection correction amount corresponding to the introduced purged fuel amount.
