EMISSION CONTROL SYSTEMS
Purge Control Solenoid Valve
The purge control solenoid valve is controlled
by the ECU; when the engine coolant tempera-
ture is low, and during idling, it closes, so that
evaporated fuel is not taken into the surge tank.
After engine warm-up, during ordinary driving, it
opens to introduce evaporated fuel to the surge
tank.

misfire and result in excessive loading of the
catalytic converter.
Avoid idling the engine for periods longer
than 10 minutes.
Your Hyundai should not be either pushed
or pulled to get it started. This can cause the
catalytic converter to overload.
Take care not to stop your Hyundai over any
combustible material such as grass, paper,
leaves or rags.
Do not touch the catalytic converter or any
other part of the exhaust system while the
engine is running.
Remember that your Hyundai dealer is your
best source of assistance.

EXHAUST EMISSION CONTROL
SYSTEM
EGR system ; For a Petrol Engine
This system helps control oxides of nitrogen by
recirculating a portion of the exhaust gases into
the intake manifold, thereby reducing cylinder
combustion temperatures.
Catalytic Converter
H020A01HP
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem-
peratures. As a result, the introduction of large
amounts of unburned petrol may cause it to
overheat and create a fire hazard. This can be
avoided by observing the following:

For a Diesel Engine
YH040A2-E
All Hyundai vehicles are equipped with oxida-
tion type catalytic converter to reduce the car-
bon monoxide, hydrocarbons and particulate
contained in the exhaust gas.
CATALYTIC CONVERTER
;
For a Petrol Engine
The catalytic converter is part of the exhaust
emission control system. Its purpose is to re-
move certain engine emission products from
the engine's exhaust. It looks something like a
muffler and is located underneath the car in the
exhaust system.

Use only unleaded fuel.
Maintain your engine in good condition. Ex-
tremely high converter temperatures can re-
sult from improper operation of the electri-
cal, ignition or M.P.I. system.

If your engine stalls, pings, knocks, or is
hard to start, take your car to your Hyundai
dealer as soon as possible and have the
difficulty corrected.
Avoid driving with a very low fuel level. If you
run out of petrol, it could cause the engine to
This system helps control oxides of nitrogen by

The EGR system helps reduce Nox (Oxides of
Nitrogen) emission gasses.
