COMPONENTS
The primary purpose of the EGR cooler (see Figure 2-10), is to cool the exhaust gases by:
Providing a coolant flow to remove heat from the gas side core.
Delta Pressure Sensor/EGR Temperature Sensor
Figure 2-11
Venturi
Monitoring the pressure differential across the venturi (adjacent to outlet of EGR cooler
see Figure 2-11 and see Figure 2-12) and the temperature of the exhaust gases
(see Figure 2-13) determine precise Mass Flow Rate Measurement.
The ECM uses the delta pressure and exhaust temperature to determine the rate of EGR flow.
