Abstract: 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.

Abstract: A diesel fuel filter for removing foreign substances and water contained in fuel used in a high-pressure fuel pump upon lubricating and cooling the high-pressure fuel pump is provided. The diesel fuel filter includes a lower cap for draining water including a double-lock cover and a double-lock pin to provide a double-lock structure to prevent fuel leakage caused by unfastening of the lower cap due to impact or vibration during driving of a vehicle.

Abstract: 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.
