The Exhaust Gas Recirculation (EGR) Cooler is an air-to-liquid heat exchanger device that uses engine coolant to reduce exhaust gas temperatures prior to recirculating them through the engineâs intake system. EGR reduces engine combustion temperature, which prevents the formation of Oxides of Nitrogen (NOx) pollutants. Before injecting spent exhaust gas into the engine, its temperature must be reduced, and the EGR Cooler accomplishes this task by reducing as much as 700 degrees F from the exhaust gas.
