Abstract
Methods and systems are provided for purging a fuel vapor canister during conditions when purge vacuum is limited, such as during boosted conditions. An exhaust-driven purge pump is used to flow positive pressure air through a canister, and purge the canister to a compressor inlet. The air is heated during the pressurization, improving hydrocarbon desorption from the canister.
