摘要： A fuel vapor recovery system and method for an automotive vehicle are disclosed. The vehicle fuel tank is vented to atmosphere via a passageway having a carbon canister to remove fuel vapors, a bladder, and a normally-closed isolation valve. When fueling the vehicle, the gases in the fuel tank displaced by entering fuel are introduced into the carbon canister where the fuel vapors are stored. The isolation valve is commanded to open to allow such flow through the carbon canister. When the vehicle is parked for a period of a day, it undergoes a diurnal temperature change which causes fuel to vaporize into the fuel system. According to an aspect of the present development, the isolation valve remains closed and the gases are contained within the bladder as it expands or contracts as the volume of gases increases or decreases in response to temperature changes.
