摘要： An aeration and deaeration device for the fuel tank (1) of an internal combustion engine (6) in which the aeration and deaeration are performed through an adsorption filter, the adsorption filter can be regenerated by backwashing with atmospheric air, the backwashing air is sent to the air intake area of the internal combustion engine, the composition of the backwashing air is determined and taken into account in control of the combustion process taking place inside the engine, should permit backwashing of the adsorption filter which has an influence on the composition of the engine exhaust gas. To this end, such a device is characterized by the following features: a sensor (9) which detects selected substance data and/or state data on the purging air is provided in a purging air line (5) carrying purging air into the intake area of an internal combustion engine (6), the area of the purging air line (5) containing the sensor (9) can be switched together with the interior of the adsorption filter (4) as a forced flow circulation line, for turning the circulation line on and off, a 3/2-way valve (8) is situated in the purging air line (5) downstream from the sensor (9), its one outlet leading to the outside of the circulation line and its other outlet leading back to the adsorption filter (4) through a bypass line (7) running parallel to the purging air line (5).
