Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To clarify the relationship between a heating value of a heater and the shape of a fuel adsorbing layer 4 to obtain the temperature regulating effect over the whole area of the fuel adsorbing layer 4. SOLUTION: The fuel adsorbing layer 4 formed inside of a canister is defined into an upper adsorbing layer 4A and a lower adsorbing layer 4b by a partitioning plate 13 in which a heater is buried. The relationship between the heating value of the heater and a thickness X of the upper adsorbing layer 4A and the lower adsorbing layer 4B is determined to satisfy that a temperature of a part nearest to a heating face of the heater, of the fuel adsorbing layer 4 is lower than an ignition point of the fuel, and a temperature of a part farthermost from the heating face of the heater is higher than a boiling point of the fuel. Whereby the desorbing performance of activated carbon C can be improved by heating the fuel adsorbing layer 4 by the heater in desorption, and the approximately full amount of the adsorbed fuel vapor can be desorbed.  As a result, as the fuel vapor does not remain in the canister, the fuel vapor flowing in adsorption can be surely and completely adsorbed.
