摘要： A fuel-mixing prevention filler neck device is provided. The fuel-mixing prevention filler neck device includes a fuel dispensing gun insertion unit that receives a fuel dispensing thereinto and a coupling unit that provides fluid communication with a bottom of the fuel dispensing gun insertion unit. The coupling unit is disposed on an exterior circumferential surface thereof with coupling protrusions for fastening with a plurality of slots formed in a filler pipe. Further, a first side of a lower portion of the coupling unit is open to form a coupling region. A misfueling prevention unit slidably moves to the coupling region to be coupled to the coupling unit. Additionally, the misfueling prevention unit is closed when a gasoline fuel dispensing gun is inserted and being opened when a diesel fuel dispensing gun is inserted.

摘要： A fuel management system for a hybrid vehicle driven by an electric motor and an internal combustion engine is provided. The system includes a check unit that detects a time in which the internal combustion engine was last operated and stores the detected time as an engine driving point in time. A controller receives the stored engine driving point in time and determines that a fuel remaining in a fuel tank is aged when a time period elapsing from the engine driving point in time reaches a set fuel leaving time period, to operate the internal combustion engine while the hybrid vehicle is driven.

摘要： A method for diagnosing fuel leakage of a vehicle includes: measuring a pressure of a fuel tank by a pressure sensor in a closed state of a fuel system during starting-off of the vehicle; measuring an inner temperature of the fuel tank by a temperature sensor; and diagnosing, by a controller, whether or not leakage occurs by performing different leakage diagnoses depending on a pressure condition of the fuel tank. Thus, the controller performs a first leakage diagnosis when a pressure value of the fuel tank, measured in the measuring the pressure of the fuel tank, is within an atmospheric pressure level; performs a second leakage diagnosis when the pressure value is higher than a positive pressure; and performs a third leakage diagnosis when the pressure value is lower than a negative pressure.
