crankcase, the fresh air mixes with blow-by
gases, then passes through the PCV valve into
the induction system.

EMISSION CON-
TROL SYSTEM
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-
sion while maintaining good vehicle perfor-
mance.

2. EVAPORATIVE EMISSION
CONTROL SYSTEM (If installed)
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.

EMISSION CONTROL SYSTEM
(If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the
Emission prohibition rules of your province,
There are three emission control systems which
are as follows.
Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and
stored in the canister. When the engine is
running, the fuel vapors absorbed in the canis-
ter are drawn into the induction system through
the purge control solenoid valve.

Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Catalytic Converter
Purge Control Solenoid Valve
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 undemeath the car in the
exhaustsystem.
The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper-
ature is low, and during idling, it closes, so that
evaporated fuel is nottaken into the surge tank.
After engine warm-up, during ordinary driving, it
opens so as to introduce evaporated fuel to the
surge tank.

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. This system supplies fresh air to the
