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： With a control apparatus of a multiple cylinder internal combustion engine, external EGR that circulates exhaust gas in an exhaust passage to an intake passage is executed, and an air-fuel ratio is feedback-controlled such that an air-fuel ratio of the exhaust gas comes to match a predetermined target air-fuel ratio. When a rich deviation in which the air-fuel ratio of a portion of cylinders is off to a rich side from the target air-fuel ratio is detected, a parameter indicative of an amount of the rich deviation is calculated. The target air-fuel ratio is corrected to the rich side according to the calculated parameter. A value of a parameter at which the rich correction is started is changed according to whether external EGR is being executed.

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.

摘要： Disclosed is a control device that is for an internal combustion engine with a supercharger and capable of handling an operation resumption request during an internal combustion engine stop period in a situation where waste-gate valve control is exercised in consideration of pumping loss at the time of internal combustion engine stop. The internal combustion engine includes a turbocharger and a waste-gate valve. When the operation resumption request is generated while the internal combustion engine is stopped due to automatic stop control, the waste-gate valve fully opens as far as the engine speed is not lower than a predetermined revolution speed. Further, self-recovery control is exercised over the internal combustion engine (or more specifically, a fuel injection and ignition operation is resumed). Meanwhile, in a case where the engine speed is lower than the predetermined revolution speed when the operation resumption request is generated, the waste-gate valve fully closes. Subsequently, stop control, which has already been initiated, is continuously exercised to bring the internal combustion engine to a complete stop. The waste-gate valve reverts to an open position in preparation for the restart of the internal combustion engine.
