摘要：
Methods and systems for fuel vapor canister purging in boosted engines are described. In one example, vapors are purged from the canister into an engine intake passage downstream of a throttle via an ejector during vacuum conditions, whereas during boost conditions, vapors are purged from the canister into an upstream inlet of a compressor via the ejector, the compressor arranged in the intake passage upstream of the throttle.
