摘要： A control apparatus for an internal combustion engine is provided, which is capable of suppressing deterioration of exhaust emission due to an unburned fuel contained in oil which enters a combustion chamber during valve stop control while preventing inflow of fresh air to a catalyst, at a time of valve return following return from fuel cut. Variable valve operating apparatuses having valve stop mechanisms capable of changing operation states of an intake valve and an exhaust valve between valve operation states and valve closed and stopped states are included. Valve stop control that changes the operation states of the intake valve and the exhaust valve to the valve closed and stopped states is performed, at a time of execution of the fuel cut. When a return request from the fuel cut with the valve stop control is detected, a fuel is supplied to a combustion chamber before the operation state of the exhaust valve is returned to the valve operation state. The fuel supply amount in this case is corrected in accordance with an amount of the unburned fuel contained in the oil which enters into the combustion chamber from a crank chamber side during the fuel cut with the valve stop control.

摘要： A control device is applied to an internal combustion engine capable of using CNG and gasoline by switching therebetween, and the CNG and the gasoline are associated, as fuel for use, with one and the other of two driving areas respectively, the driving areas being different from each other. The control device exceptionally switches the fuel for use from gasoline to CNG and implements an air-fuel ratio imbalance inspection (S6, S7), when the air-fuel ratio imbalance inspection is required for a CNG mode using CNG (S1), the engine is driving in a driving area (AR2) correlated to gasoline as fuel for use (S2), and gasoline mode using gasoline as fuel for use is ongoing (S3).
