The charcoal absorbs fuel vapors (in the old days the tank was vented to atmosphere). The purge valve allows the vapors to be sucked out of the charcoal and into the engine.
Adding JimLev's information to the diagram in this post #17 of:
- Might we be able to list, with pics (realoem diagrams ok) of ALL E39 vacuum lines?


Note: I'm having trouble finding an E39 charcoal canister photo, in situ.

Do you have one handy?
