ABSTRACT:
In an engine with an evaporative emission control system, a main fuel vapor storage canister is vented to a secondary fuel vapor storage canister disposed so as to capture fuel vapor discharged from the main canister and to receive air heated by a heat stove on the engine whereby fuel vapor within the secondary canister can be completely and rapidly purged during engine operation.
