摘要： A method for recovering vapor during an onboard refueling operation comprising the steps of: providing a flow path between a fuel tank and a purge canister; providing a valve in the flow path; providing a fuel level sensor for indicating the level of fuel in the fuel tank, and a vapor pressure sensor for indicating the pressure of the fuel vapor in the fuel tank; and actuating the valve to selectively open and close the flow path in response to signals received from the fuel level sensor and the vapor pressure sensor.
