The GMC EGR valve is just a little part on your vehicle that may cause big problems. The GMC EGR valve is one of the most integral parts on your vehicle's emissions and ignition system. In addition, it is also the main emissions control device on your exhaust gas recirculation system. The main use of your GMC EGR valve is to reduce the combustion temperature generated by your engine and as well as helps in controlling or managing the formation of oxides of nitrogen on your vehicle combustion process. It is basically located right on your intake manifold. With its small passageway opening between your exhaust and intake manifold it allows the metered amount of exhaust to flow back into your engine. In this scheme it truly decreases the combustion temperature of your vehicle. There are two types of EGR valves; in general, one works through the use of a vacuum to its control diaphragm, and the other one is activated through the use of an exhaust back pressure or electricity, which is frequently used in most vehicles nowadays. Both types allow the exhaust gas on its lower combustion temperature when it gets too high.
