Abstract
A fuel carbureted in a float chamber of a carburetor is prevented from entering through an air vent path into an air intake path during low velocity running of a vehicle. An outer vent path and an inner vent path are provided on the upstream side of an air vent path which communicates with a float chamber of a carburetor of an engine for a vehicle. The paths are alternatively selected by a solenoid valve. An opening of the inner vent path is opened in the intake duct, and an opening of the outer vent path is opened at a position sufficiently spaced away from the front face air intake. During low velocity running, the solenoid valve is selectively operated so that the outer vent path is in communication with the carburetor. During high velocity running, however, the inner vent path is in communication with the carburetor.
