Canister
YH040A2-E
For a Petrol Engine;
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
(PVC) 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 (Engine Control
Unit); when the engine coolant tem-
perature is low, and during idling, it
closes, so that evaporated 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
silencer and is located underneath the
car in the exhaust system.

sphere.

Exhaust Emission Control
System
The exhaust emission control system
is a highly effective system which
controls exhaust emission while main-
taining good vehicle performance.
