ABSTRACT:
A fail-safe system and method for automobile fuel tank wherein when the fuel filler cap is opened at fueling and the pressure in the fuel tank goes down to an atmospheric pressure level, the pressure sensor detects the pressure down and the pressure control valve provided between the fuel tank and the canister is automatically closed for a specified time. Therefore, even if a vehicle driver inadvertently forgets to switch the ignition key off at fueling, fuel does not flow out of the canister when the fuel tank is filled up. The system does not need any additional device.
