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： An internal combustion engine is provided in which a prescribed amount of fuel is injected over a predetermined period until an air-fuel ratio sensor is activated when fuel cut control of the internal combustion engine is stopped to resume normal engine operation. If an EGR gas is inducted immediately before the fuel cut control is started, the prescribed amount is reduced.

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.
摘要翻译： 在某些汽缸停用模式（例如，虚拟V-4操作模式，其中V-6发动机的两个气缸被停用），点火/燃烧可能以不均匀的间隔发生在操作气缸中。 在这种情况下，输出扭矩在点火顺序的停用气缸之后的紧随其后的操作气缸和其他操作气缸之间变化。 多缸发动机包括点火正时调整单元。 当在汽缸停用期间以不均匀的间隔发生点火时，点火正时调整单元调节每个操作气缸中的点火正时，以平滑操作气缸的输出转矩。
