Exhaust Gas RECIRCULATION (EGR) System: Notes
The EGR system used with Electronic Engine Control consists of 3 major components:
- EGR Valve and Sensor Assembly
- EGR Control Solenoids (2)
- EGR Cooler Assembly
Utilizing engine manifold vacuum to operate the EGR valve, the ECA controls EGR gas flow. When EGR valve is open, exhaust gas from exhaust manifold is directed into the intake manifold and becomes part of the combustion cycle, helping to reduce NOx emissions levels.
