Control device for cylinder direct injection type of internal combustion engine

A control device applied to a cylinder injection type of an internal combustion engine, comprising:

• a spark plug provided with a spark generation part;
• and
• an injector provided with a movable valve body and an injection hole, said injector executing an injection of a fuel into a cylinder of said engine through said injection hole by a movement of said valve body and being provided such that a spray including at least a part of the injected fuel reaches said spark generation part directly,
• the device comprising a control part configured to:
• execute a fuel injection by said injector while changing a penetration force of the injected fuel by changing a maximum value of a lift amount of said valve body in said fuel injection;
• and
• control an ignition timing for generating a spark by said spark generation part on the basis of an operation state of the engine,
• wherein said control part is configured to:
• execute the fuel injection immediately before the ignition timing as a preceding injection while controlling a timing of executing said preceding injection;
• and
• change at least an injection end timing of a said preceding injection such that a time period between the injection end timing of said preceding injection and the ignition timing under a state where a first value is set as the maximum value of the lift amount of said valve body in said preceding injection, is longer than a time period between the injection end timing of said preceding injection and the ignition timing under a state that a second value larger than the first value is set as the maximum value of the lift amount of said valve body in said preceding injection.
