Evaporating fuel control device for vehicles

摘要

Hydrocarbons (HC) absorbed in a canister are purged fully by correcting and controlling a duty percent from a base map for increasing a rate of purging evaporating fuel from the canister when one or more of the conditions indicative of an increase of evaporating fuel are detected so that degradation of the canister's performance can be prevented, release of hydrocarbons (HC) from the canister to atmosphere can be prevented by eliminating inadequate purge, and durability of the canister can be improved.
