Kia Optima Hybrid: Evaporative Emission Control System / Description and Operation

Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Emission Control System / Evaporative Emission Control System / Description and Operation

Description

The 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 a canister filled with charcoal.

The canister temporarily holds the vapor in the charcoal. The ECM will control the system in order to draw the gathered vapor into the combustion chambers during certain operating conditions. Engine manifold vacuum is used to draw the vapor into intake manifold.
