Crankcase Emission Control
Your  Hyundai  is equipped  with  an  emission
control system to meet  all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air  Resources Board.
There are three emission control systems which
are as  follows.
Fuel vapors generated inside the fuel  tank are
absorbed and  stored in  the onboard canister.
When  the engine  is  running, the  fuel  vapors
absorbed  in  the canister  are  drawn  into  the
induction  system  through  the   purge  control
solenoid valve.
System
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, which  then  pass through  the
PCV valve and  into the induction system.

Evaporative Emission  Control System
Exhaust Emission  Control 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 to
introduce evaporated fuel  to the engine.
In order  to  ensure 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.

. Evaporative Emission Control
(IncludingORVR:OnboardRefueling
Vapor Recovery)  System
The Evaporative  Emission  Control System  is
designed to prevent fuel vapors from escaping
into the  atmosphere.

Exhaust Emission Control System
(The  ORVR system  is designed  to  allow the
vapors from  the fuel  tank to be  loaded into  a
canister while refueling at the gas station,  pre-
venting  the  escape   of  fuel  vapors  into  the
atmosphere.)
The  Exhaust  Emission  Control  System  is  a
highly effective system which controls exhaust
emissions   while   maintaining   good  vehicle
performace.
