Exhaust Emission Control  System
;
For a Gasoline Engine
The  Exhaust  Emission Control  System  is  a
highly effective system which controls exhaust
emissions   while  maintaining   good   vehicle
performace.
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, which the fresh air mixes
with blow-by gases,  which then pass  through
the PCV valve into the induction system.

EMISSION CONTROL  SYSTEMS
;
For a Gasoline Engine
(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; For a  Gasoline Engine
The Evaporative  Emission Control  System is
designed to prevent fuel vapors from escaping
into the atmosphere.

Exhaust emission control system
Canister
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

H020A01HP
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.
All Hyundai vehicles are equipped with a mono-
lith type  three-way catalytic  converter   to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the  exhaust gas.
Exhaust gases  passing  through the  catalytic
converter may cause it to operate at a very high
temperature. The introduction of large amounts
of  unburned  gasoline  into the  exhaust  may
cause the catalytic  converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:
Purge Control Solenoid Valve
The purge control solenoid valve  is controlled
by the ECM; when the engine coolant tempera-
ture 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.
