Abstract:
A control device for an internal combustion engine including an in-cylinder injection fuel injection valve, and a port injection fuel injection valve, has a controller that controls injection amount ratios of the in-cylinder injection fuel injection valve and the port injection fuel injection valve in accordance with a driving condition of the engine. A fuel cut is performed at a predetermined deceleration of the internal combustion engine. The injection amount ratio of the in-cylinder injection fuel injection valve is corrected to be decreased at a fuel cut recovery at which a fuel supply is restarted from the fuel cut state, during a predetermined period from the start of the recovery.
