Fuel vapor storage canister, fuel vapor adsorbent for canister, and method of producing fuel vapor adsorbent |
摘要 |
A fuel vapor storage canister for adsorbing fuel vapor evaporated from a fuel tank of an automotive vehicle. The fuel vapor storage canister includes a casing provided with charge and purge ports at its first end and an atmospheric port at its second end. At least first and second fuel vapor adsorbent layers are respectively located near the first and second ends of the casing. In this arrangement, the first fuel vapor adsorbent layer is larger in cross-sectional area perpendicular to flow direction of fuel vapor than the second fuel vapor adsorbent layer. The first and second fuel vapor adsorbent layers respectively include first and second granular fuel vapor adsorbents. The first granular fuel vapor adsorbent has a microporous structure, while the second granular fuel vapor adsorbent has a macroporous structure.
