Patent ID: 8905005

Claim:
An evaporative fuel treatment apparatus for a vehicle having a fuel tank configured to store fuel therein, comprising: a canister having an absorbent filled therein and configured to adsorb and store the evaporative fuel; a charge channel configured to provide communication between the fuel tank and the canister; a purge channel configured to provide communication between the canister and an air-intake system of an internal combustion engine; an atmospheric air release channel connected to the canister to enable the canister to communicate with an outside, the apparatus further comprising: a direct purge channel capable of supplying the evaporative fuel from the fuel tank to the purge channel without involving the canister; a purge control valve provided in the purge channel and configured to control a communicating state between the canister and the air-intake system of the internal combustion engine by an opening and closing operation; a direct purge control valve provided in the direct purge channel and configured to control the communicating state between the fuel tank and the air-intake system of the internal combustion engine by an opening and closing operation; and a two-way valve provided in the charge channel and configured to open at a predetermined pressure, the evaporative fuel treatment apparatus further comprising: a purge mode in which the evaporative fuel adsorbed in the canister is purged to the air-intake system of the internal combustion engine by bringing the direct purge control valve into a closed state and the purge control valve into an opened state while the internal combustion engine is in operation, and a direct purge mode in which the evaporative fuel in the fuel tank is purged to the air-intake system by bringing the purge control valve into a closed state and the direct purge control valve into the opened state.
