Your Hyundai is equipped with an emission
control system to meet all requirements of the
Emission prohibition rules of your province.
There are three emission control systems which
are as follows.
1) Crankcase emission control system
2) Evaporative emission control system
3) Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through the
PCV valve and into the induction system.

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

While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and
stored in the onboard canister. When the en-
gine is running, the fuel vapors absorbed in the
canister are drawn into the induction system
through
the purge control solenoid valve.

The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper-
ature is low, and during idling, it closes, so that
evaporated fuel is not taken into the engine.
After engine warm-up, during ordinary driving, it
opens so as to introduce evaporated fuel to the
engine.

The Positive Crankcase Ventilation System is
employed to prevent air pollution caused by

The catalytic converter is part of the exhaust
emission control system. It's purpose is to re-
move certain engine emission products from
the engine's exhaust. It looks something like a
muffler and is located underneath the car in the
exhaust system.
