Fifth generation HG (2011–2024) / Hyundai Azera 2011-2024 Service Manual / Emission Control System / Evaporative Emission Control System / Description and Operation
| Description |
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 canister filled with charcoal. The canister temporarily holds
the vapor in the charcoal. If ECM determines to draw the gathered vapor
into the combustion chambers during certain operating conditions, it
will vacuum into intake manifold.
