発燃料供給通路と、この蒸発燃料供給通路を絞り弁近傍
の吸気道路内負圧に応動して導通制御する第１のパージ
制御弁と、この第１のパージ制御弁をバイパスして上記
蒸発燃料供給通路をキャニスタと連通させるバイパス通
路と、上記蒸発燃料供給通路に介装され、絞り弁下流の
吸気道路内負圧に応動してその弁開口面積を上記負圧の
増大に伴って減少すると共に、高負圧時の所定値以上で
は最小開口面積を維持する一方低負圧時の所定値以下で
は全閉となる鍔付きピストン体状の第２のパージ制御弁
とを備えた内燃機関の蒸発燃料制御装置。A canister that stores evaporated fuel generated in a fuel tank, etc., an evaporated fuel supply passage that connects this canister and an intake passage downstream of a throttle valve, and a evaporated fuel supply passage that responds to negative pressure in the intake road near the throttle valve. a first purge control valve that controls conduction through the first purge control valve; a bypass passage that bypasses the first purge control valve and communicates the evaporated fuel supply passage with the canister; In response to the negative pressure in the intake road, the valve opening area decreases as the negative pressure increases, and the minimum opening area is maintained above a predetermined value at high negative pressures, while the valve opening area decreases to the predetermined value at low negative pressures. Hereinafter, an evaporated fuel control device for an internal combustion engine is provided with a second purge control valve in the form of a flanged piston body that is fully closed.
