摘要： PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device for efficiently detecting a closing malfunction of a closing valve to seal a fuel tank without changing the internal pressure of the fuel tank into negative pressure in the regular control. SOLUTION: A closing valve 28 to control the communication state between a fuel tank 10 and a canister 26 is provided. When an internal combustion engine is stopped, the closing valve 28 is in a closed state in general, and the canister 26 is opened to the atmosphere. When the internal combustion engine is stopped, and the differential pressure exceeding a valve opening discrimination value occurs between the tank internal pressure and the atmospheric pressure, the closing valve 28 is opened. The changes in the tank internal pressure occurring before and after opening the closing valve 28 is detected. If the change in the tank internal pressure does not reach the predetermined discrimination value, the closing malfunction of the closing valve is discriminated. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device having a closing valve to seal a fuel tank for reliably preventing evaporated fuel from being emitted into the atmosphere while detecting leakage. SOLUTION: A closing valve 28 is provided between a fuel tank 10 and a canister 26. A purge VSV 36 is provided in a purge passage 34. A negative pressure pump module 52 is communicated with an atmosphere hole 50 in the canister 26. The regular control includes a treatment of setting the closing valve 28 from CLOSE to OPEN while the purge VSV 36 is closed, a treatment of setting the inside of the canister 26 to be negative pressure by a pump 74 while the purge VSV 36 is closed, and the closing valve 28 is opened, and a treatment of inspecting leakage based on the resultant pressure change. The regular treatment is prohibited if evaporated fuel is possibly blown off from the canister 26 in the step of the regular treatment. COPYRIGHT: (C)2004,JPO
