Abstract:
Methods and systems are provided for shared handling of fuel vapor purge and crankcase ventilation in an engine system. Fuel vapors from each of a canister and a crankcase are drawn into an intake manifold in a common direction during both boosted and non-boosted engine operating conditions using vacuum drawn at various aspirators. Compressor bypass flow through a first aspirator is used to enhance vacuum produced during boosted conditions while throttle bypass flow through a second aspirator is used to enhance vacuum produced during non-boosted conditions.
