ABSTRACT:
A fuel vapor storage canister includes a vapor inlet for introducing vapor into the canister and a bed of adsorbant material in fluid communication with the inlet for adsorbing vapor within the canister. A vapor purge tube is in fluid communication with the bed for purging fuel vapor from the bed. A thermoelectric cooler/heater selectively cools the inlet tube to promote condensation of vapors therein and selectively and alternatively heats the bed to promote purging of vapors from the bed and the remainder of the canister.
