Abstract
Methods and systems are provided for purging a fuel vapor canister. In one example, a method may include during boosted engine operating conditions, utilizing regulated compressed air from an engine intake to purge fuel vapors stored in the fuel vapor canister. Further, during non-boosted condition, regulated air from the intake may be utilized to purge the fuel vapor canister. The purged fuel vapors and intake air may be delivered to upstream of a compressor when operating with boost, or to an intake manifold when operating without boost.
