[SanJaxson]

The most obvious phenomenon of a faulty EGR valve in Wuling Rongguang is that it will make the engine idle extremely unstable or even stall. Here is some relevant information about EGR: 1. The EGR valve is the valve of the exhaust gas recirculation control system. A faulty EGR valve may cause symptoms such as extremely unstable idling or stalling, flashing fault lights, failure to meet annual emission inspection standards, burning engine oil, and blue smoke from the exhaust. The EGR valve is a very important and critical component in the exhaust gas recirculation device. 2. The EGR valve is a mechatronic product installed on diesel engines to control the amount of exhaust gas recirculated back to the intake system. It is usually located on the right side of the intake manifold, near the throttle body, and is connected to the exhaust manifold by a short metal pipe. Its function is to control the amount of exhaust gas entering the intake manifold, allowing a certain amount of exhaust gas to flow into the intake manifold for recirculation. The EGR valve is a very important and critical component in the exhaust gas recirculation device, used to reduce the emission of nitrogen oxides (NOX) in the exhaust gas.
