SYSTEMS
blow-by gases  being emitted from  the crank-
case.  This  system  supplies fresh  air  to  the
crankcase through  the air cleaner.  Inside the
crankcase,  the fresh  air  mixes  with blow-by
gases, then passes through the PCV valve into
the induction system.

Exhaust Emission Control  System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-
sions    while    maintaining     good    vehicle
performace.

(If Installed)
The  evaporative  emission control  system  is
designed to prevent fuel vapors from escaping
into the atmosphere.
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
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
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 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
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 engine.
After engine warm-up, during ordinary driving, it
opens so as to introduce evaporated fuel to the
engine.
