EVAPORATED FUEL PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an evaporated fuel processing device capable of making a separation to suit the amount of suction air of an engine without impairing the A/F controllability of the engine due to the hot purged, evaporated fuel even in case the amount of suction air of the engine remains small. SOLUTION: The evaporated fuel processing device is structured so that the output of its heater 5 is increased when the amount of air ia large and is made normal when the amount is small, so that there is no risk that the A/F controllability is impaired due to the over-rich of the mixture gas even when the amount of air is small. The incremental output of the heater 5 with greater amount of air will enhance the adsorbing and separating performance of an adsorbent 4 to lead to enhancement of the processing ability of a canister 2.
