Abstract: A canister includes a charge port, a purge port, an atmosphere port, a main chamber, a sub chamber, activated carbon, and more activated carbon. The charge port takes in evaporated fuel. The purge port discharges the evaporated fuel. The atmosphere port is open to the atmosphere. The charge port and the purge port are connected to the main chamber. The sub chamber communicates with the main chamber. The atmosphere port is connected to the sub chamber. The activated carbon is stored in a main volume (Vmain) in the main chamber. The more activated carbon is stored in a sub volume (Vsub) in the sub chamber. A ratio of a length L in a gas flow direction to an equivalent diameter D in a section perpendicular to the gas flow direction is 2 or more for the sub chamber. An activated carbon volume ratio (Vmain/Vsub) is 5.5 to 7.

Abstract: A canister includes a charge port, a purge port, an atmosphere port, a main chamber, a sub chamber, activated carbon, and additional activated carbon. The sub chamber communicates with the main chamber. The atmosphere port is connected to the sub chamber directly or via an additional chamber. The activated carbon is stored in a main volume (Vmain) in the main chamber. The additional activated carbon is stored in a sub volume (Vsub) in the sub chamber. A ratio of a length L in a gas flow direction to an equivalent diameter D in a section perpendicular to the gas flow direction is 2 or more for the sub chamber. A ratio of a volume of the activated carbon stored in the main chamber to a volume of the activated carbon stored in the sub chamber (Vmain/Vsub) is more than 7 and equal to or less than 10.

Abstract: 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.

Abstract: 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.
