EMISSION CONTROL SYS- TEMS
DH010B1-E
1. Crankcase Emission Control
System
The positive crankcase ventilation (PCV) 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. In- side the crankcase, the fresh air mixeswith blow-by gases, then passes through the PCV valve into the intake system. When the engine is running, the fuelvapors absorbed in the canister aredrawn into the induction system through the purge control solenoid valve. 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, itcloses, so that evaporated fuel is not taken into the surge tank. After engine warm-up, during ordinary driving, itopens to introduce evaporated fuel to the surge tank.

3. Exhaust Emission Control
System
This system helps control oxides of
nitrogen by recirculating a portion of the exhaust gases into the intake manifold, thereby reducing cylinder combustion temperatures.

2. Evaporative Emission
Control System
The Evaporative Emission Control System is designed to prevent fuelvapors from escaping into the atmo- sphere. Canister Whilst the engine is inoperative, fuel vapors generated inside the fuel tank are absorbed and stored in the canis- ter.
