Evaporative Emissions System: Description and Operation
PURPOSETo reduce HC emission. evaporated fuel from the Fuel Tank is routed through the Charcoal Canister to the Intake Manifold for combustion in the cylinders.
OPERATION
Schematic View Of Vacuum Hose Connections For The EVAP System:
Fuel vapors inside the Fuel Tank are routed to a canister containing activated charcoal, which absorbs and holds the vapors, preventing them from entering the atmosphere.
EVAP System Components - Operating Conditions:
During certain operating conditions, fresh air is drawn into and through the Charcoal Canister, flushing the vapors into the throttle body and into the intake air stream.
