What is the maintenance method for diesel engine EGR valve?

[Willie]

EGR valve, also known as Exhaust Gas Recirculation valve, is an electromechanical product installed on diesel engines to control the amount of exhaust gas recirculation in the intake system. It is a crucial component in the exhaust gas recirculation device. EGR valve failures are mostly caused by blocked passages, so it should be cleaned or replaced in time to ensure the normal operation of the engine. Information about the EGR valve is as follows: 1. The EGR valve is usually located on the right side of the intake manifold, near the throttle body, and is connected to a short metal pipe leading to the exhaust manifold. 2. The EGR valve improves engine efficiency by directing exhaust gas from the engine combustion back into the intake manifold, which helps lower the combustion chamber temperature, enhance the combustion environment, reduce engine load, effectively decrease NOx emissions, minimize knocking, and extend the service life of various components.
