In a gasoline engine intake system in which a high-load intake passage that communicates with the next system is provided independently from each other up to at least the vicinity of the intake valve, this occurs when the throttle valve of the primary carburetor system is opened at a predetermined touch angle or more. A valve interlocking mechanism is provided so that a cam that responds to the throttle valve reaches an operating position, and the cam can shift the closing position of the throttle valve of the secondary system of the carburetor in the opening direction by a required kick angle. is set to a smaller value than usual, and the vaporizer 1
An intake system for a gasoline engine, characterized in that the shape of the cam is defined so that the kick angle gradually increases as the opening of a subsequent throttle valve increases.
