Handbook & Warranty Information  book-
let in your vehicle.
Your  vehicle is  equipped  with an  emis-
sion control system  to meet all emission
regulations.
The
Evaporative
Emission
Control
System   is   designed   to   prevent   fuel
vapors  from  escaping  into   the  atmos-
phere.
(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, preventing the escape of
fuel vapors into the atmosphere.)
There  are  three  emission  control  sys-
tems which are as follows.

(3)
Crankcase emission control system
Evaporative emission control system
Exhaust emission control system
1. Crankcase emission control
system
Canister
The  positive  crankcase  ventilation  sys-
tem is  employed to  prevent air  pollution
caused by  blow-by gases  being emitted
from the crankcase.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
into the induction system.
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  surge  tank
through the purge control solenoid valve.
In order to  assure the proper function  of
the  emission control  systems,  it is  rec-
ommended   that   you   have   your   car
inspected and  maintained by an  author-
ized Hyundai  dealer in  accordance with
the maintenance schedule  in this manu-
al.
Purge Control Solenoid Valve (PCSV)
The purge control  solenoid valve is con-
trolled  by   the  Engine  Control   Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es  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.
