Evaporative Emission Control Canister: Description and Operation
Fig. 32 Charcoal canister
The purge control valve on the purge canister is controlled by intake manifold vacuum. When the purge control valve is opened, absorbed fuel vapor is
drawn from the canister into the intake manifold. When the engine is not operating, the purge control valve is opened by a return spring. The vapor
remains in the canister until vacuum is applied to the purge canister and is routed to the intake manifold.
