Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies fresh filtered air to
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.

(If Installed)
(If Installed)
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.

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

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

Catalytic Converter
HFC5013
The catalytic converter is part of the exhaust
emission control system. Its 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.
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 so
as to introduce evaporated fuel to the engine.
