Kia Sportage: Emission control system / 2. Evaporative emission control (including ORVR: Onboard Refueling Vapor Recovery)
system
The Evaporative Emission Control System is designed to prevent fuel vapors from
escaping into the atmosphere.
(The ORVR system is designed to allow the vapors from the fuel tank to be loaded
into a canister while refueling at the gas station, preventing the escape of fuel
vapors 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.
