<P>PROBLEM TO BE SOLVED: To provide an evaporated fuel treating apparatus that reduces blow-through of an evaporated fuel component to the outside from the atmospheric port. <P>SOLUTION: The evaporated fuel treating apparatus includes: a heat storage material-containing chamber 35 formed of a passage 3, inside which a fluid can flow, and provided with granulated coals or fractured coals 15a and 25a and heat storage materials 15b and 25b filled with phase-change materials, which absorb and discharge stored heat depending on the change of temperatures, in a capsule on one end side of the passage 3; a non-heat storage material-containing chamber 36 in which a granulated coal or fractured coal 30a is provided on the other end side and which does not contain the heat storage material; and a delay diffusion chamber 22 which does not have active charcoal or the heat storage material inside between the heat storage material-containing chamber 35 and the non-heat storage material-containing chamber 36. The adsorption amount of the evaporated fuel of the granulated coal or fractured coal 30a in the non-heat storage material-containing chamber 36 is made 2 vol% or more and 8 vol% or less of the total adsorption amount of the evaporated fuel of the granulated coals or fractured coals 15a, 25a and 30a, and the volume of the delay diffusion chamber 22 is larger than the volume in the non-heat storage material-containing chamber 36. <P>COPYRIGHT: (C)2013,JPO&INPIT |
