ABSTRACT:
An intake amount control apparatus of an internal combustion engine in accordance with the invention includes a control portion that controls an opening amount of a throttle valve provided in an intake passageway of the internal combustion engine and operation of a lift amount changing mechanism capable of changing a lift amount of an intake valve. The control portion controls the operation of the lift amount changing mechanism so that, prior to execution of a fuel cut control at the time of an engine deceleration, the lift amount of in intake valve becomes smaller than at the time of a normal engine idle operation where the fuel cut control is not executed.
