7 EMISSION CONTROL SYSTEMS

3. Exhaust Emission Control Sys-
tem
The Exhaust Emission Control System is a
highly effective system which controls ex-
haust emissions while maintaining good
vehicle performace.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tempera-
ture is low during idling, the PCSV closes
so that evaporated fuel is not taken into the
engine. After the engine warms-up during
ordinary driving, the PCSV opens to intro-
duce evaporated fuel to the engine.
CATALYTIC CONVERTER
!
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic
converter temperatures can result
from improper operation of the elec-
trical, ignition or multiport electronic
fuel injection.
o If your engine stalls, pings, knocks, or
is hard to start, have your Hyundai
dealer inspect and repair the problem
as soon as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause
the engine to misfire and result in
damage to the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause
the catalytic converter to overheat
and create a fire hazard.
H020A01A-AAT
All Hyundai vehicles are equipped with a
monolith type three-way catalytic converter
to reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the
exhaust gas. Exhaust gases passing
through the catalytic converter cause it to
operate at a very high temperature. The
introduction of large amounts of unburned
gasoline into the exhaust may cause the
catalytic converter to overheat and create
a fire hazard. This risk may be reduced by
observing the following:
