Claims

[Scope of utility model registration request]

A surge tank has an intake inlet opening at one longitudinal end to guide intake air that has passed through a throttle valve into the surge tank, and the surge tank branches from one side wall in the longitudinal direction, curves, and connects to each cylinder. and a control valve for controlling the supply amount of intake air bypassing the throttle valve to the surge tank, and the control valve is provided on a side wall opposite to the side wall where the independent intake passage branches. An intake system for an engine, characterized in that an intake downstream side connection port of the control valve is opened on an inner surface of the side wall.
