Within modern internal combustion engines, Exhaust Gas Recirculation (EGR) is a method to control Nitrogen Oxides (NOx) emissions, produced as a by-product during the combustion process.

The EGR system works by returning a small portion of exhaust gas to the engine's combustion chambers through the intake manifold, lowering combustion temperatures and therefore reducing the amount of NOx emitted.

The EGR valve is the main component of the EGR system and it's normally closed. It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
