  • Patent number: 6564779
    Abstract: An evaporated fuel treatment device in which performance of a canister can be improved, with the result that efficiency in treatment of evaporated fuel can be enhanced. In the evaporated fuel treatment device, a purge control valve, conventionally disposed on a purge passage, is removed, such that the canister is directly subject to a negative pressure generated on the side of an inlet pipe at the time of starting of an engine. Consequently, a great attraction force acts on the evaporated fuel adsorbed within the canister. Also, by restricting a flow of air introduced into the canister by means of a flow control valve, the negative pressure applied to the canister can further be increased. As a result, in the evaporated fuel treatment device of the invention, the amount of the evaporated fuel which can be desorbed from the canister is larger than that of a conventional device.
