Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine method, comprising: during vacuum conditions, purging canister vapors into a converging side of a nozzle, out of a diverging side of the nozzle, and into an engine intake downstream of a throttle, the throttle downstream of a compressor; and during boost, purging vapors from the canister into a zone between the converging side and a compressor inlet, the vapors not passing through the diverging side of the nozzle before entering the compres…
