With an EGR removal valve on a vehicle, the combustion temperature can be regulated, so it will not become too hot, thus preventing the nitrogen to react with other compounds. In other words, through the use of the EGR valve, it is possible to lower the combustion temperature to lower the amount of nitrous oxide produced. Therefore, this process prohibits the formation of smog that is a harmful threat to the environment.
