Control device for internal combustion engine

A control device for an internal combustion engine applied to said internal combustion engine, said internal combustion engine comprising:

• a direct injection injector capable of injecting fuel into a combustion chamber formed between an inner surface of a cylinder and a piston reciprocating in said cylinder;
• and
• a port injection injector capable of injecting said fuel into an intake port connected to said cylinder,
• wherein,
• said control device comprises a control unit for driving said direct injection injector and said port injection injector so that a state in which said fuel having an amount required for said internal combustion engine is injected from both said direct injection injector and said port injection injector and a state in which said fuel having an amount required for said internal combustion engine is injected from either said direct injection injector or said port injection injector selectively occurs depending on at least load of said internal combustion engine,
• said control unit is configured to:
• make said direct injection injector inject all of said fuel having an idle required fuel amount required for an idle operation and make said port injection injector inject no fuel from a second time to a third time so that said internal combustion engine executes said idle operation from said second time to said third time, said second time coming at or after a first time at which a predetermined engine stop request condition is determined to be satisfied, said third time coming when a predetermined period of time elapses from said second time;
• execute a fuel cut operation in which said fuel is not injected from both said direct injection injector and said port injection injector from said third time so that operation of said internal combustion engine is stopped at or after said third time;
• and
• make at least one of said direct injection injector and said port injection injector inject said fuel so that said operation of said internal combustion engine is restarted when a predetermined engine restart condition is satisfied under a state where said operation of said internal combustion engine is stopped at or after said third time.
