Abstract
The engine operational region in which the cylinder deactivation operation is performed in the cylinder deactivation control is switched between the cylinder deactivation region APand the cylinder deactivation region APdepending on whether a variable valve timing mechanism is in an operation allowed state and control of the valve timing of an intake valve is being performed, or the variable valve timing mechanism is in an operation inhibited state and the control of the valve timing of the intake valve is stopped. In this way, depending on whether the variable valve timing mechanism is in the operation allowed state or in the operation inhibited state, the engine operational region in which the cylinder deactivation operation is performed can be set so that the engine operational region is made suitable for each of these state.
