Crankcase Emission Control
System ; For a Petrol Engine
Whilst 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.
The positive crankcase ventilation
system is employed to prevent air
pollution 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 air
mixes with blow-by gases, then
passes through the PCV valve into
the intake system.
Purge Control Solenoid Valve
The purge control solenoid valve is
controlled by the ECU; when the en-
gine coolant temperature is low, and
during idling, it closes, so that evapo-
rated fuel is not taken into the surge
tank. After engine warm-up, during
ordinary driving, it opens to introduce
evaporated fuel to the surge tank.
Catalytic Converter
H020A01HP-D
The catalytic converter is part of the
exhaust emission control system. Its
purpose is to remove certain engine
emission products from the engine's
exhaust. It looks something like a
muffler and is located underneath the
car in the exhaust system.

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.
