Abstract
A tank system (1) for a motor vehicle having an internal combustion engine to which fuel is supplied from a tank (2), wherein the tank (2) is assigned, in a ventilation path to the atmosphere (7), a flushable filter device (6, 6) for being loaded with hydrocarbon vapors of the fuel. The filter device (6, 6) has multiple mutually separate activated carbon filters (6). All of the activated carbon filters (6) are connected permanently in parallel. In this way, the ventilation resistance from the tank in the direction of the atmosphere can be kept low.
Claims16
A tank system for a motor vehicle having an internal combustion engine and a tank that supplies fuel to the internal combustion engine, a ventilation path extending from the tank to atmosphere, a flushable filter device for being loaded with hydrocarbon vapors of the fuel in the ventilation path, the filter device having multiple mutually separate activated carbon filters connected permanently in parallel.
