Provided is a fuel filling port device with a protrusion structure having an outer diameter smaller than an inner diameter of a nozzle of diesel lubricator, greater than an inner diameter of a gas lubricator, and smaller than an outer diameter of the gas lubricator, that is, being able to be inserted only into the nozzle of the diesel lubricator and not to be inserted into a nozzle of the gas lubricator, which is installed at the center in a fuel filling port of a diesel vehicle to basically prevent gasoline from filling the diesel vehicle, thereby reducing dispute between a vehicle owner and a gas station as well as loss of time and economic damage. The fuel filling port device of the present invention may help prevent an oil mixing accident occurred in growing diesel vehicles, which occurs particularly in a diesel vehicle with 30 mm fuel filling port since the fuel filling port is easy to be mistaken as a fuel filling port of a gasoline vehicle. Additionally, the fuel filling port device is cheap and can be easily installed by everyone who is not an expert and used compatibly in a large, small, and diesel fuel filling port. However, when manufacturing, it needs to be considered that there are fine differences in fuel filling ports and lubricator nozzles according to the specifications of manufacturers and the stereotypes such that every vehicle use gasoline should be discarded. |
