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.

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.

Canister
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.
