After changing the required values of controlled variables of an inlet system and an EGR system (an air-fuel ratio, an EGR rate, and an intake air amount) into values of a combustion mode after switching with updating a required combustion mode mdcb, the present invention updates a combustion mode mdcbd for injection after waiting for the expiration of a delay period. Besides the update, the present invention updates the required values of a target injection pressure pc and a main injection timing ainjm, and the required values of a torque correction amount qdm, the waviness correction amount qdi, and the cylinder internal pressure correction amount qdp for a main injection amount command value qfinm into the values in a combustion mode after switching. The present invention gradually changes the target injection pressure pc, the main injection timing ainjm, the torque correction amount qdm, the waviness correction amount qdi, and the cylinder internal pressure correction amount qdp towards respective required values in the combustion mode after switching with keeping the gradual change extent of those uniform until a gradual-change period elapses. |
