5) Canister
The canister absorbs the fuel vapor during refueling standby or purge flow control.
In addition to the conventional canister construction, this canister contains a purge buffer, which uses
highly concentrated activated charcoal, in front of the purge side port. The function of the purge buffer
is to moderate the concentrated fuel vapor that is discharged from the fuel tank when the fuel
vapor-containment valve is open.
