In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.GR valve on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines.
EGR operates when conditions exist that cause pinging or valve clatter. A valve opens and circulates exhaust gas into the intake manifold to cool the combustion process. Exhaust gas is very low in oxygen. Adding exhaust gas to the fuel/air mixture, helps lower cylinder temperature.
