Vacuum Modulator, EGR: Description and Operation
Fig. 7 Exhaust Gas Recirculation System
Fig. 8 EGR System Operating Condition Chart
The EGR system recirculates the exhaust gas into the intake manifold in correct amounts according to driving conditions and engine coolant
temperatures, Fig. 7. Doing this retards the combustion, resulting in reduced amounts of nitrogen oxides (NOx) emissions.
Refer to Fig. 8 for EGR system operating conditions.
