Abstract:

To provide a failure detection method for a control valve provided in a communication passage between a fuel tank and a canister.

This evaporated fuel processing device 1 includes the canister 13 for sucking evaporated fuel from the fuel tank 3, the control valve 11 provided in a vapor passage 9 communicating the fuel tank 3 with the canister 13, and an in-tank pressure detecting means 16 for detecting pressure in the fuel tank 3. The control valve 11 is opened in accordance with a detection value previously detected by the in-tank pressure detecting means 16. When the pressure in the fuel tank 3 is not higher than a predetermined value, a variation in the opening of the control valve 11 is set to be greater than when the pressure in the fuel tank 3 is higher than the predetermined value.
