EMISSION CONTROL SYSTEMS

EMISSION CONTROL SYSTEMS

H010A01A-GAT
(If installed)
Your Hyundai is equipped with an
emission control system to meet all
requirements of the Emission prohibi-
tion rules of your province.
There are three emission control sys-
tems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) 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 maintained by an au-
thorized Hyundai dealer in accordance
with the maintenance schedule in this
manual.

1. Crankcase Emission Control
System
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air in-
take hose. Inside the crankcase, the
fresh air mixes with blow-by gases,
then passes through the PCV valve
into the induction system.

2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmo-
sphere.
Canister
While the engine is inoperative, fuel
vapors generated inside the fuel tank
are absorbed and stored in the canis-
ter. When the engine is running, the
fuel vapors absorbed in the canister
are drawn into the induction system
through the purge control solenoid
valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control Mod-
ule (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After the
engine warms-up during ordinary driv-
ing, the PCSV opens so as to intro-
duce evaporated fuel to the engine.

3. Exhaust Emission Control
System
The Exhaust Emission Control Sys-
tem is a highly effective system which
controls exhaust emissions while
maintaining good vehicle performance.
