▎ 摘  要

NOVELTY - The system (10) has a ventilation device (18) provided with a hydrocarbon retention device (24) and a ventilation path (26) in which gas exchange between a fuel tank (14) and an environment (20) is realized. The hydrocarbon retention device is provided with a filter membrane (28), which separates hydrocarbons (23) from air (25). The filter membrane is arranged in the ventilation path of the fuel tank. The ventilation path is covered through the filter membrane to prevent hydrocarbons from the tank through the ventilation path in the environment. The filter membrane comprises grapheme. USE - Fuel supply system for an internal combustion engine of a motor vehicle. ADVANTAGE - The ventilation path is covered through the filter membrane to prevent hydrocarbons from the fuel tank through the ventilation path in the environment. The system has optimized space, and prevents concentration shifts on the filter membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a fuel supply system.
