するエンジンの吸入空気量制御装置。 Intake air amount control for an engine, which includes a bypass passage that bypasses a throttle valve disposed in an intake passage, and a control valve disposed in the bypass passage that controls the amount of air flowing through the bypass passage. The device includes a start detection means for detecting the start of the engine, a first explosion detection means for detecting the first explosion of the engine, and from the start detected by the start detection motion detection to the first explosion detected by the first explosion detection means. and bypass air amount control means for controlling the control valve to reduce the amount of air flowing through the bypass passage by comparing the amount of air flowing through the bypass passage with the amount after the first combustion.
