EMISSION CONTROL SYSTEM
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
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 Module (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 driving, the PCSV
opens to introduce evaporated fuel to the
engine.

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 crank-
case. This system supplies filtered fresh air to
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.
H010A01A-AAT
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems
which are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure 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
accordance with the maintenance schedule in
this manual.

3. EXHAUST EMISSION
CONTROL SYSTEM
The Exhaust Emission Control System is a
highly effective system which controls ex-
haust emissions while maintaining good ve-
hicle performace.
H010C01S-AAT
2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station,
preventing the escape of fuel vapors into the
atmosphere.)
