NOx forms primarily due to the presence of oxygen and high temperatures. By recirculating exhaust gas back into the cylinders, EGR lowers the heat of combustion and thereby reduces NOx. EGR coolers further lower the temperature of the exhaust gas before recirculation, thereby achieving an even greater reduction in NOx.

However, the constant use of cooled exhaust gas results in the engine taking longer to reach optimal combustion temperatures. Incomplete combustion—and the associated emissions—can result during that period.

New EGR cooler has a built-in bypass channel to send exhaust gases directly back to the combustion chambers when the engine temperature is low. Sensors calculate the engine temperature and a pressure valve opens the bypass channel whenever the temperature is below a set value. This helps the engine warm faster, reducing the time for incomplete combustion.
