What is EGR? It is an electromechanical product installed on diesel engine to control the amount of exhaust gas recirculation in the intake system

EGR valve, also known as exhaust gas recirculation valve, is an electromechanical product installed on diesel engine to control the amount of exhaust gas recirculation in the intake system, and is a very important and key component in the exhaust gas recirculation device. Its function is to control the amount of exhaust gas entering the intake manifold, so that a certain amount of exhaust gas flows into the intake manifold for recirculation.

The EGR valve is usually located on the right side of the intake manifold, close to the throttle body, and connected to the intake manifold and exhaust manifold. The opening dEGRee of the valve is controlled by the vacuum pipe to determine the amount of exhaust gas transmitted to the intake manifold. 

It reduces the combustion chamber temperature, improves the engine working efficiency, improves the combustion environment, and reduces the engine burden by guiding the exhaust gas from the engine combustion to the intake manifold for combustion, effectively reducing the emission of carbon monoxide, reducing knock, and extending the service life of each component.
