Abstract
A device for the temporary storage and the pre-measured input of the volatile fuel components located in the free space of a tank into the intake tube of an internal combustion engine. The device includes a ventilator line that connects the free space with the atmosphere, into which line a storage chamber with an absorption element is placed, and a connecting line, which connects the storage chamber with the intake tube. The line may be closed by means of a valve, so that it operates in synchronicity with the butterfly valve of the intake tube.
