Abstract:
1. An intake air control apparatus for an internal combustion engine, comprising: a variably operated valve mechanism which makes at least one of an operating angle of an intake valve and a valve lift thereof variable; a deceleration fuel supply cutoff condition determining section that determines whether a deceleration fuel supply cutoff condition to cutoff the fuel supply to the engine is established; a fuel supply cutoff section that carries out a fuel supply cutoff control in a case where the deceleration fuel supply cutoff condition is established; and a valve lift and operating angle reducing section that reduces at least one of the operating angle of an intake valve and the valve lift thereof via the variably operated valve mechanism to a predetermined extreme minimal value before the fuel supply cutoff control by the fuel supply cutoff section is started in a state in which the deceleration fuel supply cutoff condition is established.
