Abstract
A system for processing fuel vapor includes a fuel tank having a pressure gauge, a gas separation membrane module having a gas separation membrane for separating fuel vapor into condensed fuel vapor and fuel lean vapor, a fuel-vapor dissolution device for introducing condensed fuel vapor discharged into the fuel tank and dissolving this condensed fuel vapor in fuel, a canister having an adsorption part adsorbing fuel vapor in fuel lean vapor and a desorption device desorbing fuel vapor from the adsorption part, and an ECU programmed to, when the internal pressure of the fuel tank detected by the pressure gauge is at least a predetermined value, drive the pump to actuate the system so as to process fuel vapor. An objective of the present invention is to provide a fuel-vapor processing system that can process fuel vapor even during periods when the engine is stopped and does not require separation of fuel vapor at multiple stages, complicated control of the flow rate of fuel vapor and the flow rate of permeated gas, or liquefaction of fuel vapor.
