Method for recovering vapor during an onboard refueling operation
摘要
A method for recovering vapor during an onboard refueling operation comprising the steps of:
- providing a flow path (28) between a fuel tank (12) and a purge canister (30);
- providing a valve (40) in said flow path (28);
- providing a fuel level sensor (20) for indicating the level of fuel in the fuel tank (12), and a vapor pressure sensor (48) for indicating the pressure of the fuel vapor in the fuel tank (12); and
- actuating the valve (40) to selectively open and close the flow path (28) in response to signals received from the fuel level sensor (20) and the vapor pressure sensor (48).
