Patent ID: 7694507

Claim:
A control apparatus of an internal combustion engine including first fuel injection means for injecting fuel into a cylinder and second fuel injection means for injecting fuel into an intake port and/or an intake manifold, comprising: fuel injection control means for performing switching between a homogeneous combustion operation and a stratified charge combustion operation in accordance with an operation state and for controlling a fuel injection ratio of said first fuel injection means and a fuel injection ratio of said second fuel injection means with respect to a total fuel injection quantity required, wherein said fuel injection control means includes: first fuel injection ratio setting means for setting said fuel injection ratios based on information correlated with the operation state of said internal combustion engine in said homogeneous combustion operation; and second fuel injection ratio setting means for setting said fuel injection ratios in place of said first fuel injection ratio setting means during a prescribed period from a switching time point from said stratified charge combustion operation to said homogeneous combustion operation, said second fuel injection ratio setting means includes means for increasing the fuel injection ratio of said second fuel injection means than the setting by said first fuel injection ratio setting means with respect to said information of the same content.
