Kia Carens: Emission control system / 2. Evaporative emission control System
The Evaporative Emission Control System is designed to prevent fuel vapors from
escaping into the atmosphere.
Canister
Fuel vapors generated inside the fuel tank are absorbed and stored in the onboard
canister. When the engine is running, the fuel vapors absorbed in the canister are
drawn into the surge tank through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled by the Engine Control Module (ECM);
when the engine coolant temperature is low during idling, the PCSV closes so that
evaporated fuel is not taken into the engine. After the engine warms-up during ordinary
driving, the PCSV opens to introduce evaporated fuel to the engine.
