Fifth generation HG (2011–2026) / Hyundai Azera 2011-2026 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

into the combustion chambers during certain operating conditions, it
will vacuum into intake manifold.
