The invention relates to a fuel supply system (10) for an internal combustion engine of a motor vehicle, comprising a fuel tank (14) and an air supply and venting device (18) for the fuel tank (14), the air supply and venting device (18) having a hydrocarbon retention device (24). In order to facilitate a simpler design of the hydrocarbon retention device (24), according to the invention the air supply and venting device (18) has an air supply and venting path (26), by means of which a gas exchange between the fuel tank (14) and the environment (20) is possible, that the hydrocarbon retentiondevice (24) has at least one filter membrane (28) which can separate hydrocarbons (23) from air (25), that the filter membrane (28) is arranged in the air supply and venting path (26) of the fuel tank(14) in such a way that the air supply and venting path (26) is covered by the filter membrane (28), and as a result hydrocarbons from the fuel tank (14) are prevented from entering the environment (20) through the air supply and venting path (26).
本发明涉及一种用于机动车辆的内燃机的燃料供给系统(10),其包括燃料罐(14)和用于所述燃料罐(14)的空气供给和排气装置(18),所述空气供给和排气装置(18)具有碳氢化合物保留装置(24)。为了有利于所述碳氢化合物保留装置(24)的更简单的设计,根据本发明,所述空气供给和排气装置(18)具有空气供给和排气路径(26),通过所述空气供给和排气路径(26)能够实现所述燃料罐(14)与环境(20)之间的气体交换,所述碳氢化合物保留装置(24)具有将碳氢化合物(23)与空气(25)分离的至少一个过滤膜状物(28),所述过滤膜状物(28)以所述空气供给和排气路径(26)被所述过滤膜状物(28)覆盖的方式布置在所述燃料罐(14)的所述空气供给和排气装置(26)中,并且结果防止碳氢化合物经由所述空气供给和排气路径(26)从所述燃料罐(14)逸入到所述环境(20)中。
