Hyundai Sonata: Evaporative Emission Control System / Description and Operation
The Evaporative Emission Control System prevents fuel vapor
stored in fuel tank from vaporizing into the atmosphere. When the fuel
evaporates in the fuel tank, the vapor passes through vent hoses or
tubes to a canister filled with charcoal.
The canister temporarily holds the vapor in the charcoal. The
ECM will control the system in order to draw the gathered vapor into
the combustion chambers during certain operating conditions. Engine
manifold vacuum is used to draw the vapor into intake manifold.
