the air cleaner where this mixes with blow-by
gases and then passes through the PCV valve
into the intake manifold from where it subse-
quently enters the combustion chamber and is
burned.

CONTROL SYSTEM
EMISSION CONTROL SYSTEMS
(Not all models)
Dependinguponthemarketforwhichthevehicle
is destined, the emission control system will
comprise one or more of the following emission
control devices.
The Evaporative Emission Control System is
designedtopreventfuelvapoursfromescaping
into the atmosphere through the fuel tank venti-
lation system.
Whilst the engine is not running, fuel vapours
generatedinsidethefueltankareabsorbedand
storedinacharcoalcanister.Whentheengineis
started, the vapours stored in the canister are
drawn into the induction system through the
purge control solenoid valve and are subse-
quentlyburned.
Thepurgecontrolsolenoidvalveiscontrolledby
the ECU; when the engine coolant temperature
is low or the engine is idling, the purge control
valveisclosedandfuelvapoursremainstoredin
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 cham-
ber.

In order that the proper functioning of the emis-
sion 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
thismanual.

Hyundai Coupe models are fitted with catalytic
convertorswhichrequirespecialoperatingcon-
siderations. The catalytic convertor serves to
oxidizecertainnoxiouselementsoftheexhaust
gases leaving the engine to reduce the level of
pollutantsemittedfromthevehicleand,provided
that care is exercised to prevent damage, the
catalyst will operate efficiently for the life of the
vehicle.
