Abstract (en)

[origin: WO9747874A1] A process and device are provided to supply the air mass flux required to regenerate the adsorption material of an adsorption filter (1) in the fuel tank venting system of an internal combustion engine while the engine is running and independently of a depression in the air intake pipe (12) of the engine. For this purpose, atmospheric air is fed at least partially and temporarily by an air pump (15) through the adsorption filter (1) to the air intake pipe (8) of the internal combustion engine while the engine is running. The air pump (15) integrated in the device makes it possible to obtain a module which is easy to produce and to handle and which contains all units of the venting system.
