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.
