Abstract
A method, comprising: purging fuel vapors from a fuel vapor canister and/or a fuel vapor bleed element to an engine intake with air routed through a transmission bellhousing. In this way, purge air may be warmed by heat generated in the transmission bellhousing during engine operation, thereby increasing desorption efficiency and reducing bleed emissions. Further, purge air may be pressurized in the transmission bellhousing to allow purging operations irrespective of intake manifold vacuum.
