Abstract

An intake flow control apparatus for an internal combustion engine eases operation of an air flow regulator and permits use of a short intake passage, thus providing a high output. The intake flow control apparatus includes an air routing member having an intake passage formed therein, and an air flow regulator opposed to an upstream-side opening of the intake passage. The air flow regulator moves in an intake axis direction while being guided by a light-weight guide structure to control the amount of intake air supplied. The air flow regulator may include plural valve elements different in operation timing, in which a valve actuator successively actuates the plural valve elements in accordance with a throttle operation to control the amount of intake air. The apparatus also includes a vacuum moderating structure for reducing the effective strength of a vacuum applied to the air flow regulator.
