PURPOSE:To surely prevent fuel from flowing into an evaporated fuel passage even if an oil level may be slanted to a great extent by providing one solenoid valve intended in use for treating evaporated fuel and opening the solenoid valve when an engine is driven. CONSTITUTION:An evaporated fuel passage 10 runs to one carburetor C2 of all carburetors in such a way that the starting end of said passage opens to a space (a2) on the fuel face in a float chamber 22, and a canister 11 is connected to its final end. A normally open solenoid valve 14 which includes a valve 13 forcibly opened by a spring 12 is disposed at the starting open end 10a of the evaporated fuel passage 10 to the float chamber 22. With an ignition switch S opened, the normally open solenoid valve 14 opens its open end 10a. When the ignition switch S is closed to operate an engine, the normally open solenoid valve 14 closes the starting open end 10a of the evaporated fuel passage 10. |
