EVAPORATED FUEL TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device capable of avoiding stall of an internal combustion engine without deteriorating fuel economy and emission of a vehicle. SOLUTION: A CPU of an engine ECU detects external load quantity L (step S2) when determines that the vehicle including an engine is in an idling operation state (Yes in step S1), and carries out control to supply evaporated fuel generated from a fuel tank to the engine (step S4) when the detected external load quantity L is not less than a predetermined threshold Lth (Yes in step S3).
