Abstract:
An evaporated fuel treatment device is provided in a canister including first to third chambers. The first chamber is provided with an inflow port and an outflow port at an end part thereof, and is connected to the second chamber. The evaporated fuel treatment device is configured as the third chamber of the canister. The third chamber has disposed therein activated carbon as an adsorbent material. The side connected to the second chamber in the third chamber is defined as second chamber side, and the side opposite to the second chamber side is defined as atmosphere side. An atmosphere port is provided at an end part on the atmosphere side of the third chamber. The third chamber is provided with a highly adsorptive layer and a low adsorptive layer which are aligned from the second chamber side to the atmosphere side.

Claim (Index 1):
An evaporated fuel treatment device which is provided in a canister,\n wherein the canister comprises: an inflow port; an outflow port; and an atmosphere port, the canister accumulating fuel vapor flowing in from a fuel tank via the inflow port and causing the accumulated fuel vapor to flow out to an internal combustion engine via the outflow port by air flowing in from the atmosphere port, wherein the canister further comprises: a first chamber having a first space which has disposed therein a first adsorbent material that is an adsorbent material for adsorbing the fuel vapor, an end part on one side in the first space being connected to an external space through the inflow port and the outflow port; and a second chamber having a second space which is connected to an end part on the other side positioned opposite to the one side in the first space, extends from the other side to the one side, and has disposed therein a second adsorbent material that is the adsorbent material, wherein the evaporated fuel treatment device is configured as a third chamber having a third space which has disposed therein activated carbon for adsorbing the fuel vapor and is connected to an end part on the one side of the second space, wherein the side on which a part connected to the second space is positioned, in the third space, is defined as second chamber side, and the side positioned opposite to the second chamber side is defined as atmosphere side, the end part on the atmosphere side in the third space being connected to the external via the atmosphere port, wherein the third space is provided with a highly adsorptive layer and a low adsorptive layer which are aligned from the second chamber side to the atmosphere side, the highly adsorptive layer and the low adsorptive layer each having the activated carbon disposed therein, and wherein the highly adsorptive layer has stronger power for adsorbing the fuel vapor than that of the low adsorptive layer, and is positioned on the second chamber side as compared with the low adsorptive layer.
