  • Passive evaporative emission control module
    Patent number: 7610905
    Abstract: An emission control module (14) includes a housing (52) that includes an atmospheric air opening (102) and a vapor emission inlet (104) for communication with a vapor region (32) of a fuel reservoir (16). A hydrocarbon filter (56) is disposed between the atmospheric air opening (102) and the vapor emission inlet (104) to passively filter vapor emissions within the vapor region (32). The housing (52) is configured for purging of the hydrocarbon filter (56) due to a low-pressure draw from the vapor emission inlet (104).
    Type: Grant
    Filed: December 21, 2007
