Evaporative Emission Control Canister: Description and Operation
EVAP Cannister
PURPOSE
The Evaporative Emission (EVAP) canister is a storage device for fuel vapors that are emitted by the fuel tank in hot soak conditions.
OPERATION
When the vehicle is at normal operating conditions, the vapors are purged from the EVAP canister. The EVAP canister is controlled by the Exhaust
Gas Recirculation/Evaporative Emission (EGR/EVAP) control solenoid. This solenoid sends vacuum to the EVAP canister purge valve (part of the
EVAP canister) which allows the passage of the fuel vapors into the intake manifold where they are mixed with air and burned in the engine. By
storing the fuel vapors and purging them into the engine at a later time, hydrocarbon emissions are reduced, and fuel efficiency is increased.
