EGR Cooler: Description and Operation

DESCRIPTION

The EGR cooler (7) cools recirculated exhaust gasses to reduce combustion temperature and a greater mass of exhaust gases can thus be circulated.
There is less nitrogen oxides as a result.

The EGR cooler (7) allows the engine and catalytic converter to reach their operating temperature quickly.
