1. Crankcase Emission Control
System
Canister
While the engine is inoperative, fuel
vapors generated inside the fuel tank
are absorbed and stored in the canis-
ter. When the engine is running, the
fuel vapors absorbed in the canister
are drawn into the induction system
through the purge control solenoid
valve.
Your Hyundai is equipped with an
emission control system to meet all
requirements of the Emission prohibi-
tion rules of your province.
There are three emission control sys-
tems which are as follows.
The positive crankcase ventilation
(PCV) system is employed to prevent
air pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air in-
take hose. Inside the crankcase, the
fresh air mixes with blow-by gases,
which then pass through the PCV
valve into the induction system.

Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECM (Engine Control
Module); when the engine coolant tem-
perature is low, and during idling, it
closes, so that evaporated fuel is not
taken into the surge tank. After engine
warm-up, during ordinary driving, it
opens so as to introduce evaporated
fuel to the surge tank.
In order to assure the proper function
of the emission control systems, it is
recommended that you have your car
inspected and maintained by an au-
thorized Hyundai dealer in accordance
with the maintenance schedule in this
manual.

Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmo-
sphere.
