Abstract
An atmosphere-vented valve (a pressure relief section) is opened in a predetermined amount so as to reduce an inside pressure of a canister to a predetermined negative pressure (S) while preventing an inside pressure in a fuel tank from becoming an excessively negative pressure by closing a charge passageway opening and closing valve (S), and purging is controlled while the canister inside pressure is being reduced, whereby from a similar principle to that of vacuum distillation, the release of vaporized fuel from an absorbent is promoted so as not only to increase the purge efficiency but also to prevent the application of an unnecessary stress to the fuel tank.
