  • System and methods for canister purging with low manifold vacuum
    Patent number: 9279397
    Abstract: A method for purging fuel vapors, comprising: purging fuel tank vapors directly from a fuel tank to an engine intake, bypassing a canister, via a venturi, while drawing canister vapors via the venturi into the purged fuel tank vapors en route to the engine intake. In this way, fuel tank vapors may be used to enable purging of a fuel vapor canister, even under conditions where there is insufficient manifold vacuum to enable a canister purge routine. By increasing the frequency of purge opportunities, bleed emissions from a saturated canister may be reduced.
    Type: Grant
