Abstract:
A control apparatus for an internal combustion engine includes phase change means (60) for advancing or retarding phases of an opening timing and a closing timing of an intake valve (62); duration change means (60) for increasing or decreasing a duration of the intake valve (62); and EGR gas amount increase means (50) for increasing an amount of EGR gas, based on an operating state of an internal combustion engine. The control apparatus further includes intake-valve closing timing advancing means (50) for advancing the intake-valve closing timing when the amount of EGR gas is increased. The intake-valve closing timing advancing means (50) advances the intake-valve closing timing by performing a first operation that advances the phases using the phase change means (60), and performing a second operation that decreases the duration using the duration change means (60), and makes a timing at which the second operation is started later than a timing at which the first operation is started.
