摘要： A problem is to provide a formed adsorber having excellent adsorption and desorption performance for fuel vapor (in particular, n-butane) of a wide concentration range from a low concentration to a high concentration.
A formed product including activated carbon fiber, granular activated carbon, and a binder is prepared. A weight ratio of the activated carbon fiber to the granular activated carbon is 5 to 95 parts by weight of the activated carbon fiber to 95 to 5 parts by weight of the granular activated carbon, in a total weight of the activated carbon fiber and the granular activated carbon, a content ratio of the binder in the formed adsorber is 0.3 to 20 parts by weight of the binder to 100 parts by weight of the activated carbon fiber and the granular activated carbon, the granular activated carbon has a total pore volume ranging from 0.90 to 2.50 cm3/g, and the activated carbon fiber has a total pore volume ranging from 0.50 to 1.20 cm3/g.-

摘要： Provided is a canister configured to adsorb and desorb an evaporated fuel originating in a fuel tank of a vehicle. The canister includes an outer case, a coupling port, an inner case, and at least one first protrusion. The outer case includes an inner surface defining an internal space extending in a first direction. The coupling port couples an inside and an outside of the outer case. The inner case is a cylindrical member accommodating therein an adsorbent for adsorbing the evaporated fuel. The at least one first protrusion protrudes outwards from an outer surface of the inner case. A fluid flows through the internal space in the first direction. The inner case is press-fitted inside the outer case so as to be accommodated in the internal space. The at least one first protrusion contacts a part of the inner surface of the outer case extending in the first direction.

摘要： Provided is an evaporated fuel treatment device. The evaporated fuel treatment device includes a main body case and a lid. The lid includes a target port, and is configured to be attached to the main body case on an attachment surface defined in advance in the main body case. The target port is configured to guide a gas in a direction intersecting a flow direction of the gas in a target adsorption chamber. The lid is configured to be rotated along a rotation direction prior to being attached to the main body case, to thereby (i) allow selection of one attachment angle from two or more attachment angles and (ii) be attached to the main body case.

摘要： A canister, mounted in a vehicle with an engine and including one or more chambers, includes adsorbents, an inflow port, an atmosphere port, an outflow port, two or more adjusting portions, and one or more coupling portions. The two or more adjusting portions are elongated members placed in at least one target chamber of one or more chamber togethers, together with corresponding one adsorbent among the adsorbents to the target chamber. The one or more coupling portions couple the two or more adjusting portions to one another. Furthermore, the one or more coupling portions are provided to the two or more adjusting portions at a position distanced from end surfaces of the two or more adjusting portions.

摘要： An evaporated fuel treatment device includes a main adsorption chamber and a sub adsorption chamber. The sub adsorption chamber includes a first adsorption layer, a second adsorption layer and a high-desorption layer. The second adsorption layer is situated closer to an atmosphere port than the first adsorption layer is, and has a lower performance of adsorbing fuel vapor than the first adsorption layer does. The high-desorption layer is situated closer to the main adsorption chamber than the first adsorption layer is, and a higher performance of desorbing the fuel vapor than the first adsorption layer or the second adsorption layer does.

摘要： Provided is an evaporated fuel treatment device including a first coupling portion, a second coupling portion, a first accommodating portion and a second accommodating portion. The first accommodating portion is configured to be disposed so as to be in communication with the first coupling portion and the second coupling portion, and to accommodate a first adsorbent. The second accommodating portion is configured to be disposed so as to be in communication with the first coupling portion via the first accommodating portion, and to accommodate a second adsorbent. The evaporated fuel adsorption capacity of the first adsorbent is lower than the evaporated fuel adsorption capacity of the second adsorbent.

摘要： A canister is provided. The canister includes an inflow port, adsorbents, an atmosphere port, an outflow port, and an adjustment member. The adjustment member includes rod-like members. The adjustment member includes a positioning member configured to enable positioning of the adjustment member in a target chamber by being insertable in a second cylinder and by not being insertable in a first cylinder. The second cylinder has a cylindrical shape, the cross sectional area of which is larger than a cross sectional area of the first cylinder.
