An Exhaust Gas Recirculation Valve is used to reduce the formation of nitrogen oxides during the combustion process. It is controlled by the engine control unit based on various engine parameters, such as load, speed, and temperature. The exhaust gas recirculation valve achieves this by recirculating a controlled amount of exhaust gases back into the engine's intake manifold, where it mixes with the fresh air-fuel mixture entering the combustion chamber.Attributes:• Improves engine efficiency by reducing the amount of oxygen in the combustion chamber• Helps prevent overheating and potential damage to engine partsApplications:An Exhaust Gas Recirculation Valve acts as a nitrogen oxide emission reduction unit in an engine by recirculating a portion of the exhaust gas back into the intake unit.
