Abstract
An evaporated fuel treatment apparatus is provided for reducing a refilling time, ensuring satisfactory adsorption/desorption performance for an evaporated fuel, and reducing the manufacturing cost through a simplified structure. The evaporated fuel treatment apparatus comprises a casing having formed therein a first chamber in communication with the fuel tank, a second chamber in communication with the first chamber, and a third chamber in communication with the second chamber and the atmosphere. Active carbons are contained in the first chamber and second chamber for adsorbing fuel components in an evaporated fuel introduced from the fuel tank. An adsorbent is contained in the third sub-chamber for adsorbing fuel components in the evaporated fuel introduced from the second chamber. The adsorbent has an air-flow resistance which is set smaller than that of the active carbons.
