Abstract
An active carbon filter intended for the fuel supply system of the internal combustion engine of a vehicle consists of a housing (), inside of which flow paths for the different operating states of the filter are established between the ports () for connection with the top space of a tank, the ambient atmosphere and the intake manifold of the internal combustion engine. Proceeding from the port (), these flow paths are characterized by chambers situated one in back of the other for pre-warming the air, an adjacent chamber () equipped with a first heating unit, an adjacent chamber () that accommodates active carbon particles, and another, adjacent chamber () that accommodates active carbon particles, is equipped with a second heating unit (), and is provided with the ports (). This yields the establishment of optimal, in particular thermal conditions for the regeneration of the active carbon particles.
