Hyundai Santa Fe: Evaporative Emission Control System / Description and operation
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 the 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 during
certain operating conditions, it will use vacuum in intake manifold to move
it.
