Abstract
An intake control apparatus for an internal combustion engine includes a variable valve operating mechanism capable of varying a lift and operation angle of an intake valve continuously and a control unit that controls an intake air amount by varying the lift and operation angle of the intake valve in accordance with an operating condition of the engine. The control unit has a learning section that learns a controlled position of the variable valve operating mechanism at a learning position that is a predetermined lift and operation angle located between a minimum value and a maximum value of the lift and operation angle that can be actually realized by the variable valve operating mechanism.
