EVAPORATIVE EMISSION CONTROL SYSTEM

7. Evaporative Emission Control System
A: GENERAL
! The evaporative emission control system prevents fuel vapors from escaping into atmosphere.
This system includes a canister, purge control solenoid valve, fuel cut valve, and the lines connect-
ing them.
! Fuel vapors in the fuel tank is introduced into the canister through the evaporation line, and are
absorbed by activated carbon in it. The fuel cut valve is also incorporated in the fuel tank line.
! The purge control solenoid valve is controlled optimally by the ECM according to the engine con-
dition.
