Engine Emission Control

COMPONENT LOCATION









INTRODUCTION
The engine emission control system comprises:
- EGR (exhaust gas recirculation) system
- Crankcase ventilation system
The EGR (exhaust gas recirculation) system is controlled by a PWM (pulse width modulation) signal from the ECM (engine control module). The system comprises an EGR (exhaust gas recirculation) valve and a gas transfer pipe.
The crankcase ventilation system is ventilated through a part load and a full load breather. The part load breather is connected through a PCV (positive crankcase ventilation) valve, which prevents air flow back into the engine.
The engine emission control system also features a Secondary Air Injection (SAI) system, comprising a pump, solenoid control valve and associated pipes. The pumps operation is controlled by the engine management system.For additional information, refer to Electronic Engine Controls Electronic Engine Controls
