Patent ID: 7021285

Claim:
A control device for an internal combustion engine, comprising: a combustion variation detecting section for detecting a combustion variation in the internal combustion engine and digitizing it as a combustion variation value; a computing section for calculating a combustion variation manipulation amount for manipulating said combustion variation in the internal combustion engine based on a combustion variation manipulation correcting amount; a combustion variation determining section for determining a combustion variation state in said internal combustion engine based on said combustion variation value; a combustion-variation-manipulation-correcting-amount changing section for changing said combustion variation manipulation correcting amount based on a result of the determination in said combustion variation determining section; and a combustion variation manipulating section for manipulating said combustion variation of said internal combustion engine based on said combustion variation manipulation amount; wherein said combustion variation manipulation correcting amount is repeatedly changed in said combustion-variation-manipulation-correcting-amount changing section until a determination result in said combustion variation determining section becomes a predetermined determination result, and wherein: said combustion variation manipulation amount includes an exhaust gas recirculation amount and an ignition timing of said internal combustion engine; and said combustion variation manipulating section manipulates said combustion variation of said internal combustion engine based on said exhaust gas recirculation amount and said ignition timing.
