Summary: | A control apparatus for an internal combustion engine includes a controller. The controller determines whether a misfire occurs in any of the plurality of cylinders. If it is determined that a misfire occurs, the controller determines whether an intake valve is unable to open due to the malfunction of a valve lift mechanism. If it is determined that the intake valve is unable to open, the controller stops operation of the fuel injection valve corresponding to a cylinder of the plurality of cylinders, in which the misfire occurs, to stop a fuel supply to the cylinder from a next intake stroke until the malfunction of the valve lift mechanism is corrected, regardless of whether the internal combustion engine stops. |
