7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
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 accordancewith the maintenance schedule in this manual. 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 the crankcase through the air intake hose. Inside the crankcase, the fresh airmixes with blow-by gases, which then pass through the PCV valve and into the induction system.

2. Evaporative Emission
Control System
The Evaporative Emission Control
System is designed to prevent fuelvapors from escaping into the atmo-sphere. Canister
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 can-ister are drawn into the induction sys-tem through the purge control sole- noid 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 fuelis 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. H010D01A-AAT
3. Exhaust Emission Control
System
The exhaust emission control system is a highly effective system which controls exhaust emission while main-taining good vehicle performance.
