The EGR valve is a crucial part of the emission control system. Its function is to re-circulate a portion of an engine's exhaust gas back to the engine cylinders. It contains the intermixing of the incoming air with re-circulated exhaust gas dilutes, lowering the peak combustion temperatures, and minimizing the amount of excess oxygen. The temperature of combustion reduction controls the engine's emission of nitrous oxides. Nitrous oxide is formed when a mix of oxygen is exposed to high temperatures and the formation happens when the fuel is burning at over 2,500 degrees Fahrenheit. With this temperature, the nitrogen in the air mixes with other gases in order to form nitrous oxide. This mixture has the capacity of altering a person's bone marrow structure if one is exposed to it in only 3-4 hours. Because nitrous oxide formation happens much faster at high temperature, the EGR valve like the Motorcraft EGR valve serves to limit the generation of it. Now, since exhaust gases do not often burn, it stays and fills up space in the combustion chamber and in the long run lowers the temperature. Older vehicles are equipped with mechanical engine EGR valves while modern vehicles have electronic EGR valves. But still, the function of the EGR valve remains unchanged. EGR systems do not require regular maintenance but, they should be checked regularly in order to ensure that they conform to emission standards. A malfunctioning EGR valve could harm your vehicles' engine if not repaired right away. A replacement is a good move to attain high performance job for the emission control system.
