7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
H010A01A-DAT (If installed) Your Hyundai is equipped with an emission control system to meet all ADR requirements. 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 systemIn order to assure the proper function of the emission control systems, it is recommended that you have your carinspected and maintained by an authorised Hyundai dealer in accor- dance with the maintenance schedulein this manual. H010B01A-AAT
1. Crankcase Emission Control
System
The Positive Crankcase Ventilation
(PVC) System is employed to prevent air pollution caused by blow-by gases being emitted from the crankcase. Thissystem supplies fresh filtered air to the crankcase through the air intake hose. Inside the crankcase, the freshair mixes with blow-by gases, which then pass through the PCV valve and into the induction system. H010C02Y-GAT
2. Evaporative Emission Control
System
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo- sphere. Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the onboard canister. When the engine isrunning, the fuel vapors absorbed in the canister are drawn into the induc- tion system through the purge controlsolenoid valve. Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECM (Engine Control Module); when the engine coolant tem- perature is low, and during idling, it closes, so that evaporated fuel is nottaken into the engine. After engine warm-up, during ordinary driving, it opens so as to introduce evaporatedfuel to the engine.
