An excessively high temperature within the combustion chamber signifies a certain amount of nitrogen oxide is released which could affect environmental surroundings. The nitrogen oxides, also known as NOX, may spread within the chamber and ultimately into the environment if your vehicle isn't equipped with Acura Legend EGR valve. In the 60's, the Exhaust Gas Recirculation or EGR system was initially presented to the public in an effort to encourage environmental awareness.

The main EGR system of your car consists of a valve that is vacuum operated to help direct exhaust gas back inside the engine's combustion chamber. As the degree of exhaust is balanced, generally there will definitely be reduced smog and NOX emissions in the environment. To help during the combustion process, the EGR valve maintains just the right level of air fusion within the chamber. A clogged EGR valve may lead to irregularities with the efficiency, including valve knock and in most situations, even rough idling. A bad valve will also decelerate the velocity of your vehicle.
