DH010B1-E
1. Crankcase Emission Control System ; For a Petrol Engine
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 airmixes with blow-by gases, then passes through the PCV valve into the intake system.
ZH010C1-E
2. Evaporative Emission Control System ; For a Petrol Engine
The Evaporative Emission Control
System is designed to prevent fuel vapors from escaping into the atmo-sphere. Canister
Whilst the engine is inoperative, fuel
vapors generated inside the fuel tankare absorbed and stored in the canis-ter. When the engine is running, the fuel vapors absorbed in the canister are drawn into the induction systemthrough the purge control solenoid valve. 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 surgetank. After engine warm-up, during ordinary driving, it opens to introduce evaporated fuel to the surge tank.
SH010D1-E
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.
Catalytic Converter H020A01HP-D
CATALYTIC CONVERTER ; For a Petrol Engine
YH040A2-E The catalytic converter is part of the exhaust emission control system. Its purpose is to remove certain engineemission products from the engine's exhaust. It looks something like a muffler and is located underneath thecar in the exhaust system.
