An Exhaust Gas Recirculation Cooler is used to reduce the temperature of the exhaust gas before it is recirculated back into the engine. It works by cooling the exhaust gas to reduce the concentration of nitrogen oxides in the engine's emissions. Cooler recirculates a portion of the exhaust gas into the engine's intake unit, where it is mixed with fresh air and fuel.

Attributes:
• Helps to reduce the environmental impact of an engine by reducing the amount of harmful pollutants that are released into the air
• Withstands the high-pressure and high-temperature conditions of the exhaust gas

Applications:
An Exhaust Gas Recirculation Cooler acts as an emissions control device that helps to reduce the amount of nitrogen oxides released into the atmosphere. The cooler achieves this by transferring heat from the hot exhaust gas to the engine coolant circulating within the cooler.
