blow-by gases  and  then passes  through the
PCV valve into the intake manifold from where
it subsequently  enters the combustion  cham-
ber and is burned.

EMISSION CONTROL SYSTEMS
(Not all models)
Depending upon the market  for which the ve-
hicle is destined, the  emission control system
will  comprise  one  or  more  of  the  following
emission control devices.
Catalytic Convertor Operation
CONTROL SYSTEM
The Evaporative  Emission Control  System is
designed to prevent fuel  vapours from escap-
ing into the  atmosphere through the fuel  tank
ventilation system.
Precautions
; For a petrol engine
Whilst the engine is  not running, fuel vapours
generated  inside the  fuel tank  are  absorbed
and stored  in a  charcoal  canister. 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 subsequently burned.
The purge control solenoid valve  is controlled
by the ECU; when the engine coolant tempera-
ture 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 subsequently burned in the combus-
tion chamber.

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 Hyundai authorised repairer
in accordance with the maintenance schedule
in this manual.

Catalytic Converter
HFC5013
Hyundai Matrix models are fitted with catalytic
convertors  which   require  special  operating
considerations. The catalytic convertor serves
to  oxidize  certain  noxious   elements  of  the
exhaust gases leaving the engine to reduce the
level of pollutants emitted from the vehicle and,
provided that care is exercised to prevent dam-
age, the catalyst will operate efficiently for the
life of the vehicle.

CRANKCASE EMISSION CONTROL
SYSTEM
The  positive crankcase  ventilation system  is
employed  to prevent  air pollution  caused  by
blow-by gases  being emitted from  the crank-
case by introducing fresh air to  the crankcase
