[0002] The EGR valve is a mechatronic product installed on a diesel engine to control the amount of exhaust gas recirculation fed back to the intake system. It is usually located on the right side of the intake manifold, close to the throttle body, and is connected to a short metal pipe leading to the exhaust manifold. 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 a very important and key component in the exhaust gas recirculation device.
