1. CRANKCASEEMISSIONCON-
TROL SYSTEM
Whilst the engine is not running, fuel
vapours generated inside the fuel tank
are absorbed and stored in a char-
coal canister. When the engine is
started, the vapours stored in the
canister are drawn into the induction
system through the purge control so-
lenoid valve and are subsequently
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 re-
main 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 subsequently 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 sub-
sequently enters the combustion
chamber and is burned.

tem
Exhaust emission control system
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 authorized Hyundai dealer in
accordance with the maintenance
schedule in this manual.

EVAPORATIVE EMISSION
CONTROL SYSTEM
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the atmo-
sphere through the fuel tank ventila-
tion system.

3. EXHAUST EMISSION
CONTROL SYSTEM
The exhaust emission control system
is a highly effective system which
controls exhaust emission while main-
taining good vehicle performance.
