1. Crankcase Emission Control
System
When the engine is started, the vapours
stored in  the canister are drawn  into
the induction system through the purge
control solenoid valve and are subse-
quently burned.
The  purge control  solenoid  valve is
controlled by the  ECU; when the en-
gine coolant temperature is low or the
engine is idling, the purge control valve
is  closed  and  fuel  vapours  remain
stored in the canister.   Under normal
running conditions when the engine is
warm, the valve opens and the vapours
are drawn into the inlet tract and sub-
sequently burned  in  the combustion
chamber.
Depending upon the market for which
the vehicle  is destined, the emission
control  system will  comprise one  or
more of the following emission control
devices.
The  positive   crankcase   ventilation
system  is  employed  to  prevent  air
pollution  caused  by  blow-by  gases
being emitted from  the crankcase by
introducing fresh air to the crankcase
through the air cleaner where this mixes
with blow-by gases  and then passes
through the PCV valve into the intake
manifold from  where it subsequently
enters the combustion chamber and is
burned.

In order that the proper functioning of
the emission control systems may be
ensured,  it is recommended that  the
vehicle is  inspected  and maintained
by an Hyundai  authorised repairer in
accordance   with  the   maintenance
schedule in this manual.

Exhaust Emission Con Trol
System
The Evaporative Emission Control Sys-
tem is designed to prevent fuel vapours
from  escaping  into  the  atmosphere
through the  fuel tank ventilation sys-
tem.
The exhaust emission control system
is  a  highly   effective  system  which
controls exhaust emission whilst main-
taining good vehicle performance.
Whilst the engine is  not running, fuel
vapours generated inside the fuel tank
are absorbed and stored in a charcoal
canister.
