ンジンの吸入空気量制御装置。 In an engine intake air amount control device in which a bypass passage for bypassing a throttle valve is provided in an intake passage and a flow control valve for controlling an intake air amount is disposed in the bypass passage, the flow rate control valve is configured to operate when the control amount is zero. 1st less than maximum flow rate
A predetermined flow rate is obtained, and as the control amount increases, the flow rate gradually increases to the maximum flow rate, then gradually decreases to zero, and then gradually increases to a second predetermined flow rate smaller than the maximum flow rate. An engine intake air amount control device characterized by using a control valve having a flow rate characteristic.
