There are three emission control sys-
tems which are as follows.

tank are absorbed and stored in the

running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.

1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase.This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
In order to assure the proper function of
the emission control systems, it is recom-
mended that you have your vehicle
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manual.
