Abstract

See full text

Methods and systems are provided for enhancing purge flow when applying shallow intake manifold vacuum. An alternate purge route that circumvents the more restrictive canister purge valve and directs purge vapors through a branched path via a less restrictive mechanical purge valve is used during low intake manifold vacuum conditions. By enabling higher purge flow rates when manifold vacuum is lower, a more complete canister cleaning is ensured.
