7- 2 EMISSION CONTROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEM (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 carinspected and maintained by an au- thorized Hyundai dealer in accordance with the maintenance schedule in thismanual. H010B01A-AAT
1. Crankcase Emission Control
System
The positive crankcase ventilation
system is employed to prevent airpollution caused by blow-by gases being emitted from the crankcase. This system supplies fresh air to thecrankcase through the air intake hose. Inside the crankcase, the fresh air mixes with blow-by gases, which thenpass through the PCV valve and 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 coolanttemperature is low during idling, the PCSV closes so that evaporated fuel is not taken into the engine. After theengine warms-up during ordinary driv- ing, the PCSV opens so as to intro- duce evaporated fuel to the engine. H010D01A-AAT
3. Exhaust Emission Control
System
The exhaust emission control system is a highly effective system whichcontrols exhaust emission while main- taining good vehicle performance.
