Hyundai Palisade (LX2) 2020-2026 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 from the fuel
tank, the vapor passes through vent hoses or tubes into canister filled with
charcoal and the canister temporarily holds the vapor in the charcoal.
If ECM determines to draw the gathered vapor into the combustion chambers at
certain operating conditions, it will use vacuum in the intake manifold to move
it.
