Cooled Exhaust Gas Recirculation

Emission regulations are becoming increasingly stringent. Therefore the emissions need to be reduced. Especially for diesel engines the reduction of the nitrogen oxides (NOx) is taking high priority. The cooled exhaust gas recirculation causes a lower combustion chamber temperature, which avoids the generation of nitrogen oxides.

EGR valves with bypass damper

Many EGR valves are provided with an electric or pneumatic bypass damper. This enables gases to be led past the EGR cooler during the warm-up phase, to get the motor and catalyst to the best operating temperature as fast as possible. The bypass is also used if high exhaust gas temperatures are needed, for example during the regeneration of the diesel particulate filters.
