Hyundai Venue (QX): Evaporative Emission Control System / Description and operation
Hyundai Venue (QX) (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 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.
Schematic Diagram Canister Canister is filled with charcoal and absorbs evaporated vapor in fuel tank. The gathered fuel vapor in canister is drawn into the intake manifold by the ECM/PCM when appropriate conditions are set.
