摘要:
An evaporative fuel treatment apparatus for a vehicle includes a direct purge channel for supplying evaporative fuel to a purge channel without involving a canister; a purge control valve for controlling communications between the canister and an air-intake system of an internal combustion engine by an opening and closing operation; a direct purge control valve for controlling communications between a fuel tank and the air-intake system by another opening and closing operation; and a two-way valve provided in a charge channel. During a purge mode of the apparatus, evaporative fuel adsorbed in the canister is purged to the air-intake system by closing the direct purge control valve and opening the purge control valve during operation of engine. During a direct purge mode of the apparatus, evaporative fuel in the fuel tank is purged to the air-intake system by closing the purge control valve and opening the direct purge control valve.
