Abstract
This disclosure relates to a separation apparatus for use in a fuel emission control system. The separation apparatus includes a tube being disposed within a conduit of the fuel emission control system and a membrane being disposed within the tube. The tube includes an introduction port for introducing a fuel vapor generated in a fuel tank. The disposition of the membrane increases turbulence of the fuel vapor in the tube and separates the fuel vapor into a fuel-rich mixture and a fuel-lean mixture. The tube further includes a discharge port for discharging the fuel-rich mixture.
