COMPONENTS

EGR Gas D elivery Pipe/Mixer

The delivery pipe provides the path for the EGR gases to flow from the EGR cooler to the intake

manifold.

Mixer

Figure 2-14 EGR Mixer

The mixer completes the EGR circuit. See Figure 2-14.

The mixer mixes exhaust gas into the fresh air supply flowing from the charge-air-cooler. Once

the air has past the mixer, the intake manifold defuses E GR gas evenly to each cylinder. Sensors

are mounted in the intake manifold to monitor the air temperature and the boost pressure.
