Abstract
A vaporized-fuel processing device for an engine stabilizes the idling operation wherein vaporized fuel within a fuel reservoir is adsorbed to an adsorbing member of a canister. While the engine is in operation, air is sucked from an air inlet into the canister with the intake-air negative pressure produced in an intake-air passage. This air separates the vaporized fuel adsorbed to the adsorbing member of the canister. Purge gas resulting from mixing the vaporized fuel into the air is sucked from a purge-gas sucking port into the intake-air passage. A throttle valve is arranged in a throttle intake-air passage of a throttle body. An intake-air pipe is disposed intake-upstream of the throttle body and is communicated with the throttle intake-air passage. The intake-air pipe has a peripheral wall to which a purge-gas sucking pipe is detachably attached. The purge-gas sucking port is provided within the purge-gas sucking pipe.
