Abstract
A multicylinder engine intake system includes: a plurality of intake paths; a plurality of bypasses detouring throttle valves and connected to the intake paths; and a common bypass control valve for opening and closing the bypasses. The bypass control valve is constituted by a valve body and an electrically operated actuator provided above the valve body and operated for opening and closing the valve body. A portion of a bypass upstream path in the bypasses on upstream side of the valve body is placed below the valve body. Idling air paths branch off from the portion of the bypass upstream path to reach the corresponding intake paths. Thus, it is possible to prevent fuel or dater droplets from staying in the bypasses and appropriately control the amount of first idling air by the bypass control valve.
