An automobile fuel tank comprises a tank body, the upper portion of the tank body is communicated with an air outlet pipe, the side portion of the air outlet pipe is communicated with an oil return pipe, the other end of the oil return pipe is communicated with the tank body, the upper end of the air outlet pipe is open and provided with a filter element, and the periphery of the filter element issealed with the inner wall of the air outlet pipe. The filter element is formed by sintering polyethylene, polypropylene or tetrafluoroethylene, the interior of the filter element is honeycomb-shaped, and the filter element is provided with pore channels which are uniform and unified in pore diameter; the filter element is provided with an oleophobic surface, pores of the filter element allow airpressure to be released, and fuel molecules cannot leak through the filter element, so that pressure in the tank body is released. Air pressure of the fuel tank can be released, fuel molecules cannotescape, and safety of the fuel tank is guaranteed.

    一种汽车燃油箱,包括有箱体,箱体的上部连通有出气管,出气管的侧部与回油管连通,回油管的另一端与箱体连通,出气管的上端呈敞开状态并设置滤芯,滤芯的周边与出气管的内壁密封。滤芯是由聚乙烯或聚丙烯或四氟乙烯烧结而成,滤芯内部为蜂巢状,滤芯具有孔径均匀、统一的孔隙通道;滤芯具有疏油性表面,滤芯的孔隙允许气压释放,而燃油分子不能通过滤芯而外泄,进而释放了箱体内的压力。本发明能释放燃油箱的气压,而燃油分子不能外泄,保证了燃油箱的安全。
