7EMISSION CONTROL SYSTEM
2EMISSION CONTROL SYSTEM
H010A01P-GAT (Gasoline) Your Hyundai is equipped with an emission control system. 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 vehicle inspected and maintained byan authorized Hyundai dealer in ac- cordance with the maintenance sched- ule in this manual. H020A01P-GAT
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 cleaner. Inside the crankcase, the fresh airmixes with blow-by gases, then passes through the PCV valve into the induction system.
H080A01P-GAT PCV Valve The crankcase ventilation system must be kept clean to maintain good engine performance. Periodic servicing is required to re- move combustion products from the PCV valve. H030A01P-GAT
2. Evaporative Emission Control
System (except canister)
The Evaporative Emission ControlSystem is designed to prevent fuel vapors from escaping into the atmo-sphere.If the fuel-vapor vent line is cloggedor damaged, the fuel-vapor mixturewill escape into the atmosphere and cause insufficient emission control. Disconnect the line at both ends, and blow it clean with compressed air. Remove the filler cap from the filler pipe, and check to see if there is evidence that the packing contact to the filler pipe is faulty. The overfilllimiter (2-way valve) installed on the vapor line between the canister inlet and fuel tank outlet must be checkedfor correct operation.
