摘要： A control device for a multi-cylinder internal combustion engine executes feedback control such that an air-fuel ratio detected by an air-fuel ratio detecting unit becomes a target air-fuel ratio, carries out external EGR, and, when an abnormal deviation that an air-fuel ratio of at least any one of cylinders deviates from the target air-fuel ratio has occurred during the feedback control, detects the abnormal deviation and an abnormal cylinder. When the abnormal deviation has been detected during feedback control and external EGR, the control device corrects the target air-fuel ratio to compensate for a detection error of the air-fuel ratio detecting unit due to the influence of specific components of exhaust gas. The control device changes the correction mode on the basis of whether the abnormal cylinder causes more intensive gas flow or equal or less intensive gas flow against the air-fuel ratio detecting unit than the other cylinders.

摘要： In some cylinder deactivation modes (e.g. virtual V-four operation mode in which two cylinders of a V-six engine are deactivated), ignition/combustion may take place in operating cylinders at uneven intervals. In this case, the output torque varies between the immediately subsequent operating cylinders after the deactivated cylinders in the firing order and the other operating cylinders. A multicylinder engine includes an ignition timing adjustment unit. When the ignition takes place in the operating cylinders at uneven intervals during cylinder deactivation, the ignition timing adjustment unit adjusts ignition timing in each of the operating cylinders to smooth the output torque of the operating cylinders.
